Cortisol can be completely stopped with a simple & cheap supplement, according to a fascinating study.

(🧵1/7)Image
Image
This study was published in 2016, evaluating the anti-stress properties of L-THEANINE.

This is an amino acid found naturally in green tea.

People were given either a mix of:

➠ L-theanine (200 mg)
➠ L-alpha glycerylphosphorylcholine (alpha GPC; 25 mg),
➠ Phosphatidylserine (1 mg)
➠ Micronized chamomile (10 mg)

Or placebo, alongside a cognitive assessment.

While the drink did have these other ingredients, they are far below (<1-10%) their typical dosing - so their impacts were likely small or negligible.

(2/7)Image
People consuming the L-Theanine drink reported markedly lower stress within the first hour.

They actually felt less stressed with the L-theanine, than they did prior, even though they were taking this assessment.

(3/7) Image
L-Theanine also completely prevented the rise in cortisol from the assessment.

While those without the L-theanine showed higher cortisol 3 hours after the test,

those with the L-theanine had LOWER cortisol.

(4/7) Image
Those on L-Theanine also had improved cognitive function.

While not statistically significant, there was a clear trend for improvements on the MTF - an assessment of:

◇ Working memory
◇ Attention
◇ Processing speed
◇ Numerical reasoning
◇ Executive function

(5/7) Image
L-Theanine also induced greater alpha waves in the brain.

This type of brain wave is associated with more controlled activity, and less stress / scatterbrained thoughts.

It is a signal of a relaxed alertness.

This was especially apparent in people with anxiety.

Why is L-Theanine so good for stress / cognitive function?

Theanine is structurally similar to the amino acid glutamate, which is a prominent neurotransmitter in the brain.

Glutamate is the primary "excitatory" neurotransmitter, and thus in excess can contribute to stress, OCD, ADHD, anxiety, even depression and other conditions.

Excess glutamate will make you feel wired and scatterbrained.

We do need some glutamate, though. It helps the growth / proliferation of brain cells, it can stimulate dopamine production, and is necessary for clarity / alertness.

Theanine acts primarily by inhibiting the release of glutamate from neurons, thus having a calming effect.

It can actually stimulate the some of the glutamate receptors, though, reaping the dopamine + neurogenesis benefits while keeping us calm.

Additionally, theanine boosts the amounts of GABA - our primary inhibitory neurotransmitter.

GABA is the opposite of glutamate, it'll chill you out, result in deep sleep, and crush anxiety.

Theanine also can raise the levels of glycine in the brain, another neurotransmitter involved in both inhibition and relaxation, as well as the glutamate-mediated formation of new brain cells.

Theanine ALSO has antioxidant and anti-inflammatory effects.

It makes sense why theanine is so effective and safe for so many different things - it really can help to balance things out in the brain, without acting non-discriminately like a drug.

Vinegar drastically reduces blood sugar and insulin levels, according to multiple clinical trials.

(🧵1/7)Image
This first paper is a review article from 2017.

They looked at studies giving people vinegar alongside meals and monitored their blood sugar and insulin responses.

Having high levels of these post meal is highly indicative of insulin resistance and is a risk for heart disease.

Apologies, I do not have the official PDF so I'm working with the raw file here.Image
Here were the included studies.

Most are looking at roughly one tablespoon of vinegar alongside a meal with carbs. Image

Why you SHOULDN'T be hysterical about vitamin C causing kidney stones, and what to do to prevent them (🧵1/10):Image
The idea that vitamin C supplementation can cause kidney stones is not completely baseless, but it does lack context.

Ascorbic acid, or vitamin C, can get metabolized in our cells to create oxalate.

Oxalate is what binds to calcium to form kidney stones in most people.

Seems pretty straightforward, BUT...Image
Ascorbic acid mainly gets converted to oxalate under conditions of high oxidative stress.

That is when ascorbic acid (AA) turns into dehydroascorbate (DHA).

But we have glutathione to help regenerate ascorbic acid from dehydroascorbate.

This depends on your entire antioxidant network.Image

FLUORIDE: The toxin in your water that destroys thyroid function.

Here's how, and what to do about it.

(🧵1/14)Image
Image
In 2024 a massive review of studies was done on the effects of fluoride exposure and markers of thyroid health.

The higher the fluoride concentration in:

◈ Drinking water
◈ Urine
◈ Serum

the higher the TSH level was - a marker of primary hypothyroidism.

TSH rises when the thyroid gland does not respond to stimulation.Image
More importantly, this study showed a marked decrease in thyroid hormones from higher water fluoride concentrations.

The active T3 thyroid hormone and the precursor thyroid hormone T4 both drop off with higher water fluoride concentrations. Image

A recent study showed that vitamin K2 was protective against every single metric of dental health measured.

(🧵1/8)Image
This paper came out in 2023 in Healthcare.

They aim was simple - look at vitamin K2 levels in relation to dental health.

They did this by looking at carboxylated osteocalcin levels - which reflects whole body K2 status. Image
Specifically they were looking at a condition called periodontitis.

This is essentially dental inflammation, especially in the gums but also impacting the teeth themselves.

These are the stages, with gingivitis being early and stage 5 being very severe. Image

An astounding study shows that 1/2 a teaspoon of baking soda lowered inflammation within hours.

(🧵1/9)Image
Study was published in 2018 in The Journal of Immunology.

Some experiment were done in rodents including baking soda in the water.

Some groups had their vagus nerves cut.

Other animals had a surgery to disturb the spleen.

Both surgeries were done to see if these tissues mediated the effect of baking soda.

Then, the human studies were done comparing drinking 2g of baking soda dissolved in water vs 2g of salt.

(2/9)Image
Animals consuming baking soda in the water showed decreased inflammation in several areas.

In both the kidneys and in the spleen, they had decreased inflammatory M1 macrophages, one of the primary immune cells.

Baking soda increased M2 macrophages, signifying that the macrophages turned into a more anti-inflammatory phenotype.

They also had:

↑IL-10 in the kidney (anti-inflammatory cytokine)
↑FOXP3 cells in blood + kidney (Treg cells, anti-inflammatory immune cells)
↓CD4 T Cells (inflammatory)
↓CD44 T cells (inflammatory)
↓TNFα macrophages (primary inflammatory mediator)

MOLD: A silent cause behind your health issues.

Fortunately, there are several tools we can use to directly bind and eliminate their toxins.

Here's 5 of the most useful (🧵1/7):

(IMPORTANT: READ UNTIL END)Image
#1 Humic acids

These are materials formed from organic matter decomposition, and it's found in shilajit.

This study showed that including them in the diet could both bind and prevent the liver cancer from a common food mycotoxin, aflotoxin B1.

Typically dosing starts at 100 mg.Image
#2 Bentonite

This is a clay substance that is highly efficient at binding to mycotoxins.

This paper showed ~50% reductions in key mycotoxins along with reduced organ damage.

Doses are higher, 500+ mg. Image
