1

Grass-fed liver is the #1 food for aging skin, packed with vitamin A, copper, zinc, and iron that serve as essential co-factors for collagen production and skin health, far outperforming $80 creams.

2

Most anti-aging facial creams contain plastics and carcinogenic chemicals that absorb through skin, burden the liver, and can actually make skin look older — a reality hidden by the FDA’s lack of cosmetic testing.

3

If eating liver makes you tired, it may be a sign of pre-existing liver damage triggering an immune reaction; taking just one capsule of grass-fed liver supplement before bed can deliver the benefits without daytime fatigue.

4

Protect your skin’s microbiome by avoiding over-cleansing and install a shower filter to remove toxic fluoride and chlorine; also avoid very low-fat, highly refined protein diets that dry out skin and accelerate aging.

Eat Grass-Fed Liver to Support Aging Skin

WhatConsume grass-fed liver regularly as a whole food (or blended, pâté, or supplement) to supply the full spectrum of co-factors — vitamin A, copper, zinc, iron — needed to build and maintain youthful skin.
WhenNot specified; implied as a regular dietary addition.
DoseOne serving size (exact amount unspecified); for those who dislike the taste, blend a small amount into ground meat or try a single capsule of liver supplement.
For whomAnyone aiming to improve skin aging, elasticity, and overall vitality, especially those with nutrient gaps or diets low in organ meats.
WhyLiver provides virtually every nutrient required for collagen synthesis, skin elasticity, healing, oxygenation, and immune protection of skin cells — far more than any topical product.
CaveatsSome people may experience fatigue after eating liver due to pre-existing liver damage (see separate protocol). Taste can be off-putting; preparation methods like soaking in lemon juice, cooking with spices and onions, blending into other meat, or using liver pâté can help mask it.

The speaker challenges the assumption that external creams or even oral collagen supplements are sufficient for skin aging. He argues that producing collagen internally requires a full team of co-factors, and liver naturally provides them in a bioavailable package. He connects the modern reliance on packaged, low-fat, and highly refined foods to nutrient deficiencies that make skin look older, and contrasts that with the dense nutrition found in organ meats. By framing liver as literally the best multivitamin for skin, he prioritizes internal nutrition over any cosmetic product. He also addresses the practical hurdle of taste by offering multiple culinary workarounds that allow people to incorporate liver without suffering through the flavor they dislike.

Mechanism

Vitamin A (retinol) is an essential element for building connective tissue and supports the skin’s immune defense against premature aging. Copper provides the cross-linking needed for skin elasticity. Zinc acts as a powerful skin healer. Iron strengthens red blood cells to enhance oxygen delivery and circulation, feeding skin tissue from within. Together, these co-factors enable the body’s own collagen-producing cells to function optimally — something topical collagen cannot bypass.

Personal experience

‘I don’t like to eat liver… I’ve blended the liver into other meat. I’ve done that where I don’t even taste it. Just put a little bit. That seems to work. Like, I put it in hamburger.’

One serving size of this food has more anti-aging, anti-wrinkle nutrients than most $80 skin products.

Also said
“Grass-fed liver contains literally every co-actor and raw material that you need to keep your skin super vibrant.”— Caps the argument by asserting liver’s comprehensive nutritional profile for skin.
“Vitamin A, retinol. It’s an essential element to building connective tissue. Also, vitamin A is essential for your immune system on the skin to protect the skin cells from getting old.”— Explains why vitamin A is pivotal both structurally and immunologically for skin.
“Copper provides the elasticity to the skin. You also need zinc for many reasons. One being it’s a great healer of the skin. This food is also loaded with iron to strengthen the red blood cells to give you oxygen and to help your circulation.”— Breaks down the trio of copper, zinc, and iron — each addressing a distinct anti-aging mechanism.

Take One Grass-Fed Liver Capsule Before Bed if Liver Food Causes Fatigue

WhatSwallow a single capsule of grass-fed liver supplement at bedtime to obtain skin-supporting nutrients without daytime tiredness, and to potentially improve sleep.
WhenBefore bed.
DoseOne capsule of grass-fed liver in supplement form.
For whomIndividuals with a history of liver stress (from poor diet, alcohol, viruses, chemicals) who notice tiredness after consuming dietary liver.
WhyFor people with pre-existing liver damage, eating whole liver can trigger a mild immune reaction via resident memory T-cells, raising histamines and causing fatigue. A small encapsulated dose at night bypasses this while still delivering nutritional benefits and may enhance sleep.
CaveatsThis is not a treatment for liver damage; it’s a workaround. If fatigue persists or other symptoms arise, addressing the underlying liver issue is important. Start with one capsule to gauge tolerance.

The speaker shares a very personal observation from his own experience and clinical practice. He explains that many people can lose weight on low-fat, high-refined-protein diets but end up with dull hair and weathered skin because they’re missing the fat-soluble vitamins and co-factors found in organ meats. In his own case, years of eating poorly left his liver vulnerable, and when he tried to reap the benefits of liver, the fatigue was counterproductive. The discovery of the capsule-before-bed strategy allowed him to enjoy the skin and overall health benefits without the side effect. He also differentiates this reaction from a typical food allergy — it’s not a permanent intolerance but a consequence of hepatic memory cells.

Mechanism

Pre-existing liver damage leads to the presence of resident memory T cells that can recognize and react to proteins in dietary liver. This triggers an immune cascade that increases histamine levels, resulting in tiredness. By taking a minimal dose in supplement form, the immune reaction may be avoided or minimized, and the small amount can still supply micronutrients. The timing at night aligns with the body’s repair processes and may even promote better sleep.

Personal experience

‘What I found is if I take just a small amount, like one capsule of grass-fed liver in a supplement before bed, it helps me sleep better. It doesn’t bother me through the day, and I actually can get the benefit of that liver without consuming the liver because I don’t like it.’

the liver has these cells called resident memory tea cells and they can actually react to dietary liver when you eat it. And so when you eat liver, sometimes you might get tired and you’re thinking, do I have an allergy to liver or do I have some problem with liver? Why is it making me tired?

Also said
“it has to do with some pre-existing damage that can then create a little bit of immune reaction that can actually increase your histamines and make you tired.”— Pinpoints the histamine-mediated mechanism behind the fatigue.
“if I take just a small amount, like one capsule of grass-fed liver in a supplement before bed, it helps me sleep better.”— Provides the specific, effective dosage and timing that solved his problem.

Install a Shower Filter to Remove Fluoride and Chlorine

WhatAdd a filter to your showerhead to eliminate fluoride and chlorine from the water that contacts your skin.
WhenAs soon as possible, for every shower.
For whomAnyone concerned with skin health, particularly those living in areas with treated municipal water.
WhyFluoride and chlorine are highly toxic and harsh to the skin, accelerating damage and aging.

Fluoride and chlorine, very, very toxic, very, very harsh. So, get a filter for your shower.

Gentle Skin Care to Preserve the Microbiome

WhatAvoid over-cleansing, aggressive exfoliation, and harsh scrubbing; be very light when washing the skin.
WhenDuring daily skincare routines.
For whomAnyone, especially those prone to dry or aging skin.
WhyThe skin hosts a protective layer of beneficial microbes; stripping this microbiome removes a critical defense, making the skin more vulnerable to environmental damage.
Mechanism

The skin microbiome acts as a frontline barrier and communicates with the immune system. Disrupting it through excessive cleansing can lead to inflammation and impaired barrier function.

There’s a layer of microbiome that is there to protect you. So, you have to be very gentle about when you exfoliate the skin. I just recommend that you go really light on the skin because there’s all these microbes on your skin that are beneficial. When you pull those off, now we don’t have the protection.

Avoid Very Low-Fat, Highly Refined Protein Diets for Skin Appearance

WhatDo not follow diets that combine very low fat with lean, highly processed protein isolates — including certain ketogenic approaches that severely restrict fats — because they dry out the skin and accelerate an aged look.
WhenWhen choosing any dietary pattern.
For whomIndividuals who are weight-loss-focused but want to preserve skin vitality, particularly those considering plans like the ‘Ideal Protein’ protocol.
WhyExtremely low-fat intake, paired with low-quality refined proteins and synthetic vitamins, starves the skin of essential fatty acids and fat-soluble nutrients needed for a youthful, moisturized complexion.

The speaker notes that in his clinical practice he observed that people on such diets lost weight but their skin and hair looked depleted and much older, a trade-off he considers unhealthy. He specifically calls out the ‘Ideal Protein’ system as an example where synthetic vitamins and soy protein isolates fail to support true skin nourishment.

Mechanism

Fat is a structural component of cell membranes and is required to absorb vitamins A, D, E, and K. Without adequate quality fats, the skin loses its lipid barrier, leading to water loss, dryness, and a worn appearance.

Personal experience

‘I would notice people that would consume that. It’s just like a bunch of synthetic vitamins with really low quality raw material. And they would lose weight, but they would look old. Their skin would look dried out. Their hair would look dried out.’

they would lose weight, but they would look old.

“it’s really hard on the body and it’ll make you look older.”— Generalizes the aging effect beyond the specific diet he witnessed.

cosmetic-toxicity

Reading the ingredients of top-selling anti-aging creams revealed that many contain plastics and carcinogenic chemicals that absorb through the skin, enter the bloodstream, and accumulate in the liver — undermining skin health rather than helping it.

Why this matters: The speaker personally reviewed popular product labels and was shocked to find that expensive creams rely on toxic chemicals, directly contradicting consumer expectations of safety and efficacy.

Background

The public assumes that premium skincare products are tested and benign, and many believe that topical collagen can be absorbed to fight wrinkles.

The speaker explains that while collagen molecules are too large to pass through the skin, the other chemicals in the creams — plastics, carcinogens — readily absorb into the bloodstream. The liver must then process these toxins, and the cumulative burden can accelerate the appearance of aging skin. He contrasts this with the natural route of supplying skin-supporting nutrients internally, arguing that the creams marketed as anti-aging may actually contribute to the problem by taxing the body’s detox systems. He also notes that this isn’t a fringe issue; it affects major best-sellers that people assume are safe.

Personal experience

‘I actually read the ingredients. It was shocking to me. They’re putting plastics, chemicals, things that cause cancer.’

They’re putting plastics, chemicals, things that cause cancer.

Also said
“Some of them actually have collagen in these lotions. You can’t put collagen topically and think it’s going to be absorbed. It’s not.”— Directly undercuts a common marketing claim that topical collagen improves skin.
“But all these other chemicals in the cream will. It goes right into the skin. It goes into the bloodstream and then it starts to build up in your liver and now the liver has to deal with it. It has to get rid of the toxicity and then the skin starts looking older.”— Describes the toxicokinetics that make these creams counterproductive for skin aging.

fda-cosmetics-regulation

The FDA operates on an honor system for cosmetics with no mandatory third-party testing, allowing thousands of chemicals to remain in U.S. products while the EU has banned 1,600.

Why this matters: A stark regulatory fact that exposes a significant consumer protection gap most people are unaware of.

Background

Many consumers believe the FDA rigorously tests and approves personal-care products before they reach the market.

The speaker points out that the FDA allows the cosmetics industry to self-regulate; there is no pre-market approval or routine third-party validation. He contrasts this with the European Union, which has banned hundreds of chemicals deemed unsafe for cosmetics. This means American consumers using products on their largest organ are unknowingly exposed to substances that other jurisdictions consider too risky. The difference between 30 banned chemicals in the US and 1,600 in the EU illustrates how little oversight exists, making label vigilance essential.

In the EU, they actually banned 1,600 chemicals in cosmetics, but in the US, they only ban 30.

Also said
“You would think that the FDA does third-party testing. Absolutely not. It’s an honor system, so industry has to do their own testing. But with cosmetics, there’s no testing.”— Clarifies the specific failure point — the absence of mandatory testing for cosmetics.

Grass-Fed Liver Capsules

Supplement

The speaker presents this as an alternative for those who dislike the taste of liver or experience fatigue after eating it. He personally uses one capsule before bed to avoid daytime tiredness and improve sleep, while still obtaining the skin-supporting nutrients.

Because whole liver can trigger an immune reaction in people with past liver stress, the capsule form provides a practical solution. The supplement allows for a tiny, controlled dose that circumvents the histamine-related fatigue. He does not endorse a specific brand but strongly recommends the grass-fed label to ensure nutrient density and avoid contaminants. The suggestion is grounded in his own trial-and-error process and clinical observation of diets that fail to support skin health.

vs alternatives

Compared to eating stove-top liver, the capsule eliminates the taste barrier and the fatigue reaction; compared to topical creams, it provides internal co-factors that actually reach skin-building cells.

Personal experience

‘What I found is if I take just a small amount, like one capsule of grass-fed liver in a supplement before bed, it helps me sleep better.’

Or grass-fed liver pills.
