Oxidative stress is a very important but far more complicated topic than the average person is made to believe.
Here's what you need to know.
Thread🧵
*Standard disclaimer that this does not constitute medical advice*
Oxidative stress is characterized by the overproduction of reactive oxygen species (ROS), which can induce mitochondrial DNA mutations, damage the mitochondrial respiratory chain, alter membrane permeability, and influence Ca2+ homeostasis and mitochondrial defense systems.
Calcium homeostasis refers to the maintenance of a constant concentration of calcium ions in the extracellular fluid.
It includes all of the processes that contribute to maintaining calcium at its “set point.”
Because plasma [Ca2+] rapidly equilibrates with the extracellular fluid, ECF [Ca2+] is kept constant by keeping the plasma [Ca2+] constant.
Maintaining a constant plasma [Ca2+] is important for things such as nerve transmission and conduction, cardigan contractility, blood clotting, cell to cell adhesion and of course bone formation.
Now a free radical attack occurs directly at complexes in the mitochondrial respiratory chain.
Mitochondria are normally protected from oxidative damage by a multilayer network of mitochondrial antioxidant systems which consist of superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase together with a number of low molecular weight antioxidants such as α-tocopherol and ubiquinol.
These molecules are particularly effective in scavenging lipid peroxyl radicals and preventing free radical chain reactions of lipid peroxidation.
Cumulative oxidative injuries to mitochondria, triggered by endogenous metabolic processes and/or exogenous oxidative influences, cause mitochondria to progressively become less efficient.
As mitochondria progressively lose their functional integrity, ever-greater proportions of oxygen molecules reaching them are converted to ROS.
So the numerous and disparate mitochondrial functions include the synthesis of most of the ATP present in the cell, apoptosis, ion homeostasis, cellular stress response, antioxidant control, redox regulation, mitophagy and the involvement in various biosynthetic pathways.
Oxidative stress occurs when there is an imbalance between free radical production and their detoxification.
Free radicals are unstable compounds that lead to cell destruction and chronic inflammation.
An atom or group of atoms with an unpaired electron is called a free radical.
A free radical can steal electrons from a stable molecule, creating a new free radical and initiating a chain reaction.
This electron-grabbing is called oxidation and can set up a chain reaction, creating new free radicals and damaging important molecules along the way, similar to how one falling domino can bring down countless more.
Antioxidants are molecules that can donate an electron to stabilize and neutralize free radicals.
An antioxidant can "stop" the free radical chain reaction in its tracks by donating an electron and then the antioxidant itself becomes a free radical.
But antioxidants are not very reactive themselves and have processes for quick stabilization.
Free radicals are a natural byproduct of metabolic reactions and of exercise, and it’s normal to have low levels of free radicals in the body.
With enough antioxidants present, free radicals can be kept in check so that they aren’t dangerous.
However, too many free radicals and not enough protection from antioxidants creates a situation called oxidative stress.
Free radical development is unavoidable, but human bodies have adapted by setting up and maintaining defense mechanisms that reduce their impact.
The body’s two major defense systems are free radical detoxifying enzymes and antioxidants.
Free radical detoxifying enzyme systems are responsible for protecting the insides of cells from free radical damage.
An antioxidant is any molecule that can block free radicals from stealing electrons. antioxidants act both inside and outside of cells.
The three major enzyme systems and the chemical reactions they catalyze are:
1)Superoxide Dismutases (SOD).
They are essential for free radical detoxification and these enzymes either have manganese, copper or zinc as a cofactor.
2)Catalase.
These enzymes convert hydrogen peroxide to water and oxygen and finish the detoxification process that SOD starts.
3)Glutathione Peroxidases.
These selenium dependent enzymes also convert hydrogen peroxide to water and oxygen.
The body can synthesize some antioxidants, but others must be obtained from the diet.
There are two antioxidants that the body synthesize:
1) Glutathione (which contains a sulfur group that can donate an electron to a free radical, thereby stabilizing it).
2) Uric acid.
There are many different antioxidants in food as well.
-Antioxidant vitamins (Vitamin E, Vitamin C) donate their electrons to free radicals to stabilize them.
-Antioxidant phytochemicals (beta-carotene and other carotenoids) may inhibit the oxidation of lipids or donate electrons.
-Antioxidant minerals act as cofactors within complex antioxidant enzyme systems (superoxide dismutases, catalase, glutathione peroxidases described earlier) to convert free radicals to less damaging substances that can be excreted.
1)Vitamin E
Functions: Protects cellular membranes and prevents glutathione depletion.
Because vitamin E is fat-soluble, its antioxidant capacity is especially important to lipids, including those in cell membranes and lipoproteins.
For example, free radicals can oxidize LDL cholesterol (stealing an electron from it), and it is this damaged LDL that lodges in blood vessels and forms the fatty plaques characteristic of atherosclerosis, increasing the risk of heart attack, stroke, and other complications of cardiovascular disease.
After alpha-tocopherol interacts with a free radical it is no longer capable of acting as an antioxidant unless it is enzymatically regenerated.
2)Vitamin C
Functions: Protects DNA, RNA, proteins and lipids and aids in regenerating vitamin E. Vitamin C’s ability to easily donate electrons makes it a highly effective antioxidant.
Since it is water-soluble, it acts both inside and outside cells to protect molecules in aqueous environments.
Vitamin C also plays a vital role in regenerating vitamin E after it has acted as an antioxidant, allowing it to be recycled and used again.
3)Selenium
Functions: Cofactor of free radical detoxifying enzymes, maintains glutathione levels, aids in regeneration of vitamins C and E.
Selenium is an essential trace mineral that is part of the structure of at least 25 proteins in the body with functions in thyroid hormone metabolism, DNA synthesis, reproduction and protecting the immune system.
As part of antioxidant enzymes, selenium helps to regenerate other antioxidants, including vitamin C.
These enzymes also protect lipids from free radicals, and, in doing so, spare vitamin E.
4) Carotenoids from sources such as pumpkin, squash, peaches, apricots which function as free radical scavengers.
5) CO2
C02 besides being a great antioxidant, is very essential for our metabolic health since it stabilizes and even activates mitochondria.
CO2 is a great anti-inflammatory, a great tool for someone to protect himself against ammonia and its byproducts, it can speed up the detoxification of polyunsaturated fatty acids and it’s a great tool to boost your performance (both mental and physical) as well.
How to increase CO2?
Two quick ways are:
1)The Buteyko breathing technique which is great for asthma, will help you with increasing CO2 levels.
2) Thiamine (B1) (especially pre workout)
3) Bag breathing
BUT, the most powerful antioxidant is not vitamin C, E or even glutathione.
Even though all of these are extremely important since each one has unique roles within the human body (for example, glutathione is critical for detoxification) the most powerful antioxidant is free and it's called melatonin.
Melatonin, chemically known as N-acetyl-5-methoxytryptamine, is classified as an indoleamine that is derived from the amino acid tryptophan.
It is evolutionarily ancient and present in organisms from bacteria to humans.
Now technically speaking, since it is synthesized in many non-endocrine organs and doesn't target a specific organ it’s not a hormone (melatonin fits this in the pineal context only).
So melatonin also acts as a paracrine and autocrine signaling molecule, influencing cellular processes across multiple tissues without requiring endocrine-specific pathways.
-It inhibits cancer cell proliferation, induces apoptosis, and enhances immune surveillance.
Melatonin is crucial for our immune system, gut health, skin health, brain health and is even linked with erectile dysfunction.
For example:
-Melatonin regulates gut motility, protects the mucosal barrier and modulates the gut microbiota.
-It reduces hypertension, improves endothelial func
But it’s not hard to understand why melatonin has these effects.
For example, melatonin as an amphipathic free radical scavenger (it has hydrophilic and hydrophobic nature and this dual solubility gives it broader reach (it goes through membranes and blood alike for example)), neutralizes free radicals like:
-Hydroxyl radical: A ROS capable of damaging DNA, proteins, and lipids.
Melatonin neutralizes this with a reaction rate constant near the diffusion limit making it one of the most efficient scavengers of this radical.
-Superoxide anion : A precursor to other ROS, produced during ETC leakage.
-Hydrogen peroxide.
-Peroxynitrite.
"Is melatonin that effective?"
Yes.
A single melatonin molecule can neutralize up to 10 ROS/RNS through its metabolites compared to classical antioxidants like vitamin C (1:1 scavenging ratio).
Not only that but unlike other antioxidants, melatonin does not exhibit significant pro-oxidant activity.
After donating electrons, its reaction products such as N1-acetyl-N2-formyl-5-methoxykynuramine, or AFMK are either inert or continue to scavenge radicals, creating a “cascade” effect.
It also enhances the body’s endogenous antioxidant defenses by upregulating key enzymes and molecules such as the GSH system (glutathione) where melatonin increases GSH levels and the activity of GSH-related enzymes such as γ-Glutamylcysteine ligase, glutathione peroxidase, glutathione reductase, superoxide dismutase, catalase and heme oxygenase-1.
Melatonin’s hydrophobic properties also make it especially effective at preventing lipid peroxidation (a chain reaction where ROS damage polyunsaturated fatty acids in cell membranes) where melatonin interrupts the propagation phase of lipid peroxidation by neutralizing lipid peroxyl radicals and stabilizing membrane fluidity.
And finally when it comes to libido and reproduction melatonin can modulate gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus for example.
It also reduces amyloid-beta production by inhibiting β-secretase (BACE1) (an enzyme that cleaves amyloid precursor protein (APP) into Aβ) and enhancing Aβ clearance by upregulating enzymes like neprilysin.
Or, when it comes to the immune system it stimulates the production of several types of immune system cells such as natural killer cells and CD4+ cells but also it inhibits Warburg metabolism by keeping pyruvate flowing into the TCA cycle and when the immune response is overactive, melatonin reduces inflammatory mediators and neutrophil infiltration.
Wrapping up with diving a bit deeper into redox.
When we have an interaction where an oxidizing substance loses electrons and a reducing substance gains electrons, we have a redox reaction.
An easy-to-understand example of a redox reaction is the rusting of iron (where iron loses electrons and oxygen receives electrons (and thus acts as an oxidizing agent)).
So in a redox reaction -> both reduction and oxidation occur.
Also terms such as oxidation, oxidizing agent, reduction, reducing agent and redox are not that hard to understand.
But this transfer of electrons is not a small thing. It's a fundamental process for life itself and when we interrupt it, problems will inevitably happen.
Even when our bodies break down glucose and fat redox reactions occur.
Now, ROS can in fact cause a lot of trouble but here's the deal, some of the them have beneficial roles and are necessary for processes such as apoptosis to run smoothly.
Otherwise we wouldn't adapt to literally having thousands of them.
Or you can think of it in terms of oxidative stress (something that harms the redox state of a cell) and oxidative eustress.
So when it comes to ROS, it's all about balance/the equilibrium.
In this journey redox cofactors or redox pairs (they participate in the transfer of electrons in a number of redox reactions ) such as:
-NAD and NADH
-NADP and NADPH
-Ubiquinone and ubiquinol
-GSSG and GSH
-FAD+ and FADH2
-FMN and FMN2
will be of vital importance.
Wtf are all these?
An easy place to start is with the following: NADH stands for "nicotinamide adenine dinucleotide plus hydrogen (H)" NADH (and FADH2) are generated for example during glucose metabolism via glycolysis and the tricarboxylic acid cycle or β-oxidation of fatty acids and are oxidized to NAD+ (and FAD) while protons are pumped to the inner mitochondrial membrane through respiratory complexes I, III, and IV (NADH is the product and NAD is the reactant)
NAD+ is synthesized from four precursors: tryptophan, nicotinic acid (pyridine-3-carboxylic acid), nicotinamide (nicotinic acid amide), nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR).
So from the get go, two things you can do in order to support redox is trying to get off statins, not over consuming food and getting enough B vitamins.
Especially B2 since it's also essential to the formation of the coenzymes FMN and FAD and the synthesis of the niacin-containing coenzymes, NAD and NADP, from tryptophan involves the FAD-dependent enzyme, kynurenine 3-monooxygenase so a dietary deficiency of riboflavin can decrease the production of NAD as well.
Other things you can do in order to support these include:
-Getting quality sleep in a dark room + all the nutrients that are needed for melatonin such as vitamin D and B vitamins.
You can approach this from multiple angles but we will approach it through OXPHOS since a major function of it is to consume NADH and recycle NAD+.
Guess what increases OXPHOS? Melatonin.
Then supplemental tools regarding the NADH/NAD + ratio in general include:
-Quercetin
-Blackseed oil
-M. Blue
So if you want to add something extra choose the one that's more suitable for you.
Things such as hesperidin and naringenin are also shown to help with it but not a lot and can have a bigger downside in the doses that need to be used compared to these 3.
Now what are potential symptoms of messed up redox?
*First you can test the erythrocyte sedimentation rate if you want.
Then, symptoms include things such as anemia, inability to detox properly that can show in the skin and liver, fatigue, low libido/energy in general, very low LDL, sleep issues, dry skin, high cortisol and getting sick very often are the classic ones.
So what you can do in order to improve your redox potential besides the things already mentioned?
-Get natural sunlight first thing in the morning
-Get enough vitamin K and CoQ10
-Avoid pesticides
-Quality seafood
-Avoid alcohol
-Moderate exercise (just get about and walk every day, lift, run/fight/swim etc 3-4/week)
-Blue light blocking programs/glasses
-Some molybdenum since it also is needed for FAD and FMN
-Remember that zinc and BCAAs are crucial for α-MSH
-Avoid things that have sodium fluoride
-Avoid heavy metals
-Ground
-Get thyroid supportive nutrients such as vitamin D, selenium, zinc, iodine etc since thyroid hormones affect flavokinase activity quite a lot and FAD synthetase a bit.
-Lower stress
-Sweat
-Potassium (very very high redox potential).
-Support acetyl-CoA, GGCX etc with other means could also come into play.
-Magnesium
-Regulate iron properly (besides nutrients such as magnesium, B vitamins, copper, zinc, vitamin D etc you'll have to fix your gut if you've been struggling with anemia for a long time)
-Some cold exposure

It's George.
First and foremost, let's see why multivitamins are a scam and why you should take your hard-earned money and purchase some real food instead.
For starters, realize that the claim for that multivitamins extend lifespan has been debunked for a long time and that you have higher chances of living longer if you are religious (not a joke).
Then, another big problem regarding this is that supplements overall, even though certain ones can be VERY helpful at times, lack transport proteins and all nutrients work synergistically.
For example:
-Selenium, sulfur, iodine, CoQ10, manganese, vitamin E, B2, iron.
-Thiamine, manganese and magnesium.
-B6 and B2.
-Zinc and copper.
-Retinol, DHA, E and B2.
-Vitamin K and retinol.
-Potassium and sodium.
-Choline and B9.
-B5 and K.
-Iron, B2, B12, B9 copper, D, retinol and C.
-Vitamin D, magnesium and retinol.
Etc
So when we eat a piece meat for example, we are not consuming just one or a few nutrients without transport proteins compared to an iron supplement for example.
On the flipside, when we consume a multivitamin that has every single nutrient, this might sound good but it’s really not.
“This pill provides me with every nutrient i need (on paper)”.
Sounds good but it’s not how our body works.
-Calcium, zinc and iron for example compete for absorption in the small intestine through DMT1.
-Then vitamin E in large amounts can interfere with some of the effects that vitamin K has such as its role in blood clotting, high doses of zinc can reduce folate absorption, high doses of vitamin C can reduce the availability of B12 to a great extent and excessive vitamin A can interfere with vitamin D’s ability to regulate calcium.
Jeremy Renner was run over by a 14,300-pound snowplough while trying to prevent it from hitting his nephew.
He was airlifted to the hospital, had more than 30 broken bones and yet somehow he has achieved a remarkable recovery.
This was partly possible thanks to peptides.
So here's the Avengers' peptide stack.
Thread🧵
It’s George.
Peptides can legitimately help with almost every goal people chase today:
-Extreme fat loss
-Improved memory recall, mood, mental clarity, focus etc
-Healing gut issues
-Healing common gym injuries
-Restoring libido and sexual function
-Rebuilding a broken immune system
-Slowing biological aging
And many more…
BUT, peptides are also one of the deepest, most confusing rabbit holes in modern health and performance.
So take 10 minutes to read this before you buy a single vial.
First, the non-negotiable disclaimers: 1. Nothing here is medical advice. 2. Target the root cause of your issues as well.
Peptides are amplifiers, not magic wands. 3. Scams are everywhere in 2025. 4. Talk to an actual doctor. 5. Stacking 5–10 peptides with no bloodwork is playing Russian roulette with expensive water.
Different peptides need different environments (PHs etc), have different half-lives and act on different receptors/sites.
General idiot’s rules of thumb:
-You don’t need more than 3 peptides at a time, most likely unless you are almost dying.
-If the liquid in your syringe turns cloudy once you mix your peptides, they are ruined.
-Cerebrolysin and GHK-CU should not be paired with anything.
-Do not stack BPC-157 or TB-500 with anything related to GH.
-Space injections at least 30 minutes apart.
Jeremy Renner himself has stated that he takes 3 months off peptides and does 2-3 months on.
Here's what i eat in a day to support my:
-Hormones
-Mood
-Gut
-Cardiovascular health
-Immune system
-Libido
-Skin health

It's George.
The purpose of this thread is for you to get ideas and become more interested when it comes to the impact that food has on our bodies.
This is not "the perfect" or "ideal" meal plan.
Coming up with a perfect diet plan is like coming up with a perfect workout plan.
Past a certain point, it will be heavily affected by your goals, training history, current injuries, old injuries, what the person has access to and so on.
The same thing is true for coming up with a “perfect” diet plan.
We need to know the goals of the person, issues that he might be struggling with, how much money he can spend and so on in order to make up a “perfect” diet plan.
So: just take ideas and data from this instead of treating it dogmatically.
Meal 1 (breakfast).
Yes, i eat breakfast since meal timing is NOT irrelevant for our health when every single thing in the human body follows a circadian pattern.
This meal consists of:
-Pasture raised eggs + mushrooms cooked in coconut oil
-Raw goat's kefir with some raisins, one Brazil nut, raw honey (this one has some propolis), kiwis, Ceylon cinnamon, glycine (3 grams), vanilla extract, taurine (1 gram), colostrum, bee pollen, berries and a bit of pomegranate.
-Nettle root gelatine + pomegranate
Supplements: 950mg of magnesium acetyl taurate, 400mg of cistance, 250IUs of full spectrum vitamin E
Here are some supplements that don't and can actually help you in a variety of areas ranging from your brain and gut health all the way to your hormones and skin health.

Note: This is about supplements indeed but if you do not get sunlight, exercise, eat whole foods, try to avoid vices such as excessive alcohol consumption and so on, then supplements will not save you.
Plenty of foods have more benefits that not only compared to the supplements at a low/medium price point but a very high as well. If a supplement, had the history and benefits of kefir for example, it would sell a lot. It’s just that you can only make so much profit from foods. I can’t sell you for example a $30 bottle of kefir yet i can very easily sell someone a $30 bottle of probiotics.
The right supplements CAN be useful and maybe even life saving. I am not dismissing them. At all. This is why we will talk about them.
This is just about having the right priorities.
Also, every single of these supplements that are mentioned will backfire for some people.
It's mathematically impossible not to.
If only 3.000 people read this and out of them 300 choose to use one, it's impossible for one of them to not react badly to it.
Does this fact make the supplement bad? No.
It makes it bad within a certain context.
So, read the studies that are linked.
Now let's talk about the supplements (not presented by order of importance).
Number 1: Magnesium.
Magnesium is involved in over 3700 enzymatic reactions in the body.
So without enough magnesium, nothing really works. But supplement wise, which form should you pick?
Here's a basic breakdown
Form 1: Magnesium citrate
This is a quite bioavailable form (not as much as glycinate or malate though in many cases) that combines magnesium with citric acid but because of this (most commercial citric acid comes from Aspergillus species), you should only use it to resolve constipation and if you have MCAS or histamine intolerance you should not use it.
Form 2: Magnesium oxide.
Throw this in the trash.
This is just a cheap form that results in the creation of pro-oxidant compounds (obviously) with a 4% bioavailability (to put this into perspective, glycinate can reach up to 40% in some cases).
Form 3: Magnesium glycinate.
This is a form where magnesium is bound to glycine and the form that most people should start with since it’s pretty bioavailable, cheap and it’s great for supporting sleep and stress reduction.
Form 4: Magnesium malate.
This is a form where magnesium is paired with malic acid (a compound that’s found in apples).
It’s perfect for people who either battle aluminum toxicity or just focus on overall detoxing.
All forms of magnesium can help by lowering aluminum retention in bones and tissues overall but malic acid can also bind certain heavy metals such as aluminum.
The effects are mild and you can not rely just on this for aluminum toxicity, but it’s something good to know in my opinion. Compared to other oral forms, it seems to be better for muscle recovery as well and support the krebs cycle more.
Form 5: Magnesium threonate
This form, has gained a lot of popularity for the overall benefits it can have on the brain and that’s because it crosses the blood-brain barrier. It’s a form where magnesium is bound to threonic acid (a metabolite of vitamin C).
Form 6: Magnesium acetyl taurate
If you have high blood pressure, anxiety and want to focus on your overall CVD health, this form is for you.
Form 7: Magnesium chloride
This form where magnesium is bound to chloride, is typically used for muscle recovery but it’s also great for people who have serious digestive issues and can’t absorb a lot of things.
Disclaimer: If you are extremely deficient in magnesium and decide to use MgCl, it will sting, a lot.
From 8: Magnesium sulfate (Epsom salts)
This from where magnesium is paired with sulfate is also great for muscle recovery but not ideal for increasing the levels within our bodies.
Note 1: If you have profound gut issues and for whatever reason you also react badly to topical forms of magnesium. Magnesium l aspartate hydrochloride is your best bet since it does not really alter gastric pH or binds hydrochloric acid.
Note 2: When it come to bicarb, it could reduce calcium buildup in soft tissues a bit and help with constipation. But it's quite expensive and if you choose to make it yourself, make sure that it stays cold, not overconsuming in order to not dilute my stomach acid etc.
While almost everyone is looking at expensive biohacks, proper sauna use is still one of the best and proven ways to:
-Reduce fatigue in patients with chronic fatigue syndrome
-Rapidly alleviate depression
-Detox from industrial toxins
-Support the immune system
-Enhance physical performance
-Promote myelination
-Improve cardiovascular health
-Protect against neurodegenerative diseases
-Alleviate chronic pain
-Resolve insomnia
and more.
Here’s the ultimate guide to sauna therapy.
Thread🧵
*Standard disclaimer that nothing in this thread should be used as a substitute for medical advice*
For the few of you who might be unaware, sauna therapy involves controlled exposure to heat, typically in a traditional (hot rock/steam) sauna (160-200°F, 70-100°C) or an infrared sauna (120-140°F, 49-60°C), inducing hyperthermia and sweating.
This triggers a cascade of physiological responses, including activation of the HPA axis, sympathetic nervous system and heat shock protein (HSP) pathways.
These responses drive adaptations in neuroendocrine, cardiovascular, immune and integumentary systems, contributing to the following benefits.
But besides these, saunas have been a cornerstone of wellness practices for centuries, from the sweat lodges of indigenous cultures to the Finnish saunas embedded in modern spa culture.
So let's see some benefits (some of which we've known for 30+ years).
Number 1: Mood enhancement and depression reduction.
In one study, a single infrared sauna session (at 135-140°F for 30 min) reduced depression symptoms by ~50% in patients with major depressive disorder.
Not only that, but the effects persisted for six weeks.
This outperformed SSRIs (3-4x effect size) and exercise (2x effect size).
Another study on mildly depressed patients with fatigue and appetite loss reported significant improvements in appetite and mental complaints after infrared sauna therapy.
