If you buy supplements off of Amazon, you need to read this: Image
One of the biggest problems Amazon has is counterfeit products, specifically supplements.

Increased reports of fake vitamins, protein powders, and other health products being sold on the platform have surged in recent years. Image
Why is this happening? A major culprit is Amazon's commingled inventory system.

This means products from different sellers, whether they be authentic or not, are pooled together in the same bins at Amazon warehouses. Image
This means that if you order a supplement for Amazon, you might think you're getting it from your chosen seller.

But with co-mingled inventory, Amazon ships whichever unit is closest regardless of which seller provided it. Image
This is serious shit.

Counterfeit supplements have been found to contain everything from harmless fillers like rice and flour to dangerous substances, sometimes including undeclared pharmaceuticals, allergens and heavy metals. Image
Brands like Now Foods and Fungi Perfecta have discovered multiple counterfeit versions of their supplements sold on Amazon, sometimes by dozens of different storefronts.

Some fakes even tested positive for drugs like Viagra. Image
For us consumers, this means that you can't always trust the label or the seller rating you see on Amazon.

Even products that say "sold by Amazon" can be affected if commingled inventory is used.
To fight this, Amazon has introduced product programs like Project Zero and product serialization to help brands fight counterfeits.

Sellers can opt out of commingled inventory by using Amazon-specific barcodes, but many products are still at risk. Image
The best way to get around this? Buy direct from the seller.

Until Amazon fully addresses the risk of commingled inventory counterfeit supplements will always remain a threat.

Also, always check for third-party testing and be wary of deals that seem to be too good to be true.
I hate to be the bearer of bad news, but it's better that you hear this now instead of blindly ordering your next supplement off of Amazon.

One more thing to add is that if this is happening to supplements, you can be damn sure that this is happening to other items that Amazon sells as well.

Stay safe out there and make sure that you are buying from the actual seller's account or from the seller themselves.

The Top 4 Most Underrated Supplements

1) CoQ10
2) Glycine
3) L-theanine
4) Psyllium husk

Here's why 👇🏼
1) Coenzyme Q10 (CoQ10)

Your mitochondria need this to produce energy.

Without it, your cells run on fumes.

Here's the issue: CoQ10 levels drop as you age. And if you're on a statin, they drop even faster.

Supplementing can improve energy, heart health, and exercise recovery.
How to take CoQ10:

Take 100-200mg daily with a meal containing fat. Fat increases absorption significantly.

Use the ubiquinol form if you're over 40. It's more bioavailable than ubiquinone.

Most people notice improved energy within 2-4 weeks.

If I woke up 20 pounds overweight and needed to lose it all by summer, this is EXACTLY what I'd do:

1. Stop eating at least 3-5 hours before bed. Set a hard stop. This prevents horrible food decisions and improves the quality of your sleep, which regulates hunger the next day.
2. Multiply your bodyweight by 12. That will be your daily calorie intake.

3. Multiply your bodyweight by .7, and that will be the daily grams of protein you need to eat to maintain/build muscle while burning fat.

4. To keep it easy, focus on hitting your calories and protein.
5. Fill your daily nutrition with these foods:

Greek yogurt
Water, coffee, and tea
Lean ground beef (extra-lean if you can)
Chicken breast and thighs
Turkey (ground or breast)
Fatty fish
Eggs and egg whites
Cottage cheese
Leafy greens
Potatoes​
Shellfish
Beans and lentils
Berries
Apples, oranges, kiwi, and grapefruit for higher-fiber fruit
Green cruciferous vegetables
Other high‑volume veg (cauliflower, zucchini, mushrooms, peppers, asparagus, cucumbers)

8 health trends that need to die in 2026:

1) Cold plunging.

Good for dopamine but studies show it blunts muscle growth and it doesn't improve recovery in a meaningful way.

For most people it's become a virtue signaling marathon on Instagram rather than an actual health tool.
2) Extreme "clean eating."

The moment you label food "clean" or "dirty" you've started a war with your plate.

I've watched this push people into disordered eating and social isolation.

You can be lean and healthy eating whole foods diet with room for your favorite foods.
3) Obsessive biohacking gadgets.

CGMs when you're not diabetic. 4 wearables on your wrist. Biofeedback devices on your nightstand.

You're turning normal body variation into anxiety.

Steps. Sleep. Weights. Nature. That covers 90% of the game. Stop overcomplicating it.

1 in 3 Americans are insulin resistant and it's silently killing them from the inside.

What most don't realize is you can reverse it in 3 to 6 months without a single medication.

Here's the exact protocol on how to do it (bookmark this): Image
8 Warning Signs of Insulin Resistance

1. Excess belly fat
2. Brain fog
3. Constant hunger
4. Low energy
5. High inflammation
6. High blood pressure
7. High blood sugar
8. High Triglycerides
It's a sign of high glucose and high insulin.

Your cells ignore insulin's signal to absorb glucose thus your body pumps out more insulin to compensate.

The result is fat storage, chronic fatigue, brain fog, and type 2 diabetes.

The good news is this is fixable with the right systems.

If you want to live to 100 or longer track these 6 key metrics:

1. Cardiorespiratory fitness

What to track: VO₂max, one mile run times or 3 mile cycle times.

Your cardio system is one of the best predictors all-cause mortality.
2. Muscle strength and lean mass

What to track: grip strength, FFMI, basic strength standards.

Low strength and muscle mass are hallmarks of frailty and higher death risk as we age.

High strength and muscle mass equal a better quality of life.
3. Autonomic nervous system health

What to track: heart rate variability (HRV) and resting heart rate trends.

These reflect stress resilience and recovery capacity, not just “fitness.”
