1

Add one scoop of collagen powder to your morning coffee daily to supply 4–10 g of glycine, supporting skin, joints, sleep, gut, and detoxification.

2

Glycine, which makes up one-third of collagen, is a conditionally essential amino acid that most people are deficient in because modern diets avoid collagen-rich gristly meats and connective tissue.

3

10% of ingested collagen survives digestion as signaling peptides that communicate with fibroblasts to trigger tissue repair—a unique benefit not obtained from muscle meat or whey protein.

4

Collagen production peaks at age 17 and declines with age, stress, sugar, and seed oils, but dietary collagen can restore it; ensure your collagen powder includes vitamin C for optimal absorption.

Daily Collagen in Coffee

WhatAdd one scoop of collagen powder to your morning coffee, stir until dissolved, optionally add a touch of cream.
WhenMorning, daily.
DoseOne scoop (providing 4–10 g of glycine) per day.
For whomAnyone, especially those over 40 or experiencing loose skin, joint pain, poor sleep, gut issues, or signs of collagen loss.
WhySupplies glycine and collagen peptides to improve skin elasticity, joint health, hair quality, deep sleep, gut integrity, detoxification, blood sugar stability, and more.
CaveatsEnsure the collagen powder includes vitamin C for optimal absorption. Avoid products with MSG or unnecessary additives. If using pork rinds as an alternative, choose MSG-free.

The speaker argues that modern diets are severely lacking in collagen because people avoid gristly meat and do not eat nose-to-tail. As we age, collagen production declines, leading to sagging skin, joint deterioration, poor sleep, and leaky gut. Supplementing with collagen powder is an easy, tasteless way to bridge the gap. He personally adds a scoop to his coffee with a touch of cream. The glycine in collagen directly enhances deep delta wave sleep, repairs the gut lining, supports liver detoxification via glutathione, stabilizes blood sugar, and even helps prevent hair graying. The unique collagen peptides also signal fibroblasts to repair tissues. He emphasizes that muscle meats and whey protein do not provide these benefits, making collagen supplementation uniquely important.

Mechanism

Collagen provides glycine, which is a precursor to glutathione (the master antioxidant), supports GABA for sleep, repairs intestinal tight junctions, enhances insulin sensitivity, and fuels catalase to prevent hydrogen peroxide buildup. Additionally, 10% of collagen peptides survive digestion and act as signaling molecules to fibroblasts, stimulating new collagen synthesis and tissue repair. Vitamin C is a cofactor for collagen cross-linking, so pairing them optimizes results.

Personal experience

The speaker, age 60, says he adds a scoop to his coffee with cream and contrasts his current fragility with his teenage resilience: at 17 he could jump off a roof without injury, but now would break a bone, illustrating collagen loss with age. He implies he uses this protocol himself.

I want you to try this tomorrow morning. Just add one scoop of this in your coffee. ... You stir it up, dissolves nicely, there's no taste. I add a touch of cream, but boy, what it does to your body is next level.

Also said
“As far as glycine goes, you want to have between 4 and 10 g per day, and you can easily get that from a scoop of collagen.”— Specifies the target glycine dosage.
“And if you are taking a collagen powder, make sure it comes with vitamin C, because that allows the collagen to work on our bodies much better.”— Adds the crucial caveat about vitamin C co-administration.
“Another way to get collagen is through bone broth, or take a whole chicken, the entire thing, put it in the Crock-Pot, and cook it all day.”— Offers a whole-food alternative for those who prefer not to use powders.

Eat collagen-rich whole foods

WhatConsume bone broth, slow-cooked whole chicken with skin, fish with skin, or MSG-free pork rinds to increase dietary collagen intake.
WhenRegularly as part of the diet.
For whomThose who prefer whole foods over powders or want additional dietary sources.
WhyProvides natural collagen and glycine without supplements, mimicking ancestral eating patterns.
CaveatsAvoid pork rinds with MSG. Slow cooking (e.g., Crock-Pot) maximizes collagen extraction from bones and connective tissue.

Another way to get collagen is through bone broth, or take a whole chicken, the entire thing, put it in the Crock-Pot, and cook it all day. You will have an end product that's loaded with collagen.

Also said
“When you consume fish or chicken, make sure the skin is on it.”— Simple dietary tip to increase collagen.
“Pork rinds, without MSG, is not a bad way to get some collagen, too.”— Unconventional but accessible source.

Collagen peptides as fibroblast signaling molecules

10% of ingested collagen survives digestion as small peptides that act as signaling molecules to fibroblasts, instructing them to repair and rebuild connective tissue—not just providing raw building blocks.

Why this matters: Challenges the common assumption that dietary collagen is simply digested into amino acids for general use; reveals a unique cell-communication role that explains why collagen supplementation is uniquely necessary.

Background

The mainstream view is that all proteins are broken down into amino acids and used wherever needed. The speaker argues that collagen contains specific peptide sequences that resist complete digestion and have hormone-like effects.

The speaker explains that 90% of collagen goes to the scaffolding or raw material for connective tissue, but 10% takes a different pathway. These peptides are not random; they are specific chains that survive digestion and travel to fibroblasts, the cells responsible for synthesizing and repairing collagen and other extracellular matrix components. This signaling function means that without dietary collagen, you miss a critical repair signal, even if you consume plenty of other protein. This insight reframes collagen from a mere structural protein to a functional food that actively directs tissue maintenance.

10% of all the collagen that you consume ends up as these little peptides that actually communicate to something called fibroblasts. These are the cells that help repair your tissues and rebuild collagen.

Also said
“90% of the collagen goes into the scaffolding or the raw material that builds all this connective tissue. But, 10% uses a different pathway. It survives digestion as these smaller little chains of amino acids called peptides.”— Clarifies the dual pathway and the unique fate of the 10%.
“So, unless you're consuming food with collagen, you're not going to get this little thing right here, which is super important for repair.”— Emphasizes that other protein sources lack these signaling peptides.

Widespread glycine deficiency from modern diet

Body protein is 30% collagen, but typical dietary protein is only 1–3% collagen, creating a massive glycine deficit because people avoid gristly, collagen-rich meats and do not eat nose-to-tail.

Why this matters: Quantifies the mismatch between physiological composition and dietary intake, explaining why even high-protein diets may be deficient in glycine and why collagen supplementation is not just for skin.

Background

Ancestral diets included skin, cartilage, tendons, and bone broth, providing ample glycine. Modern preferences for tender muscle meat and processed foods have eliminated these sources.

The speaker points out that 30% of the body's protein is collagen, yet most dietary protein—steak, chicken breast, fish fillet, eggs, whey—contains only 1–3% collagen. Tenderness is inversely related to collagen content; people love tender meat and discard the gristly parts. Because the body can synthesize only limited glycine, this dietary shift results in chronic insufficiency. Glycine is needed for glutathione synthesis, sleep, gut repair, blood sugar regulation, and more, so the deficiency has broad health consequences beyond connective tissue.

Out of all of your body's protein, 30% of it is made up of collagen. That might not mean much to you until you realize that most of the dietary protein you're consuming is only like 1 to 3% collagen.

Also said
“The more tender the meat, because people love tender meat, the less the collagen. People don't like to chew the gristly, tough meat, but in reality, that's where you get a lot of collagen.”— Explains the dietary preference that drives deficiency.
“And yes, it's true that our body can make some glycine, but not very much. And so, most people are very deficient in this thing called glycine.”— Highlights the limited endogenous synthesis.

Glycine prevents premature hair graying via catalase

Glycine is required for the enzyme catalase, which breaks down hydrogen peroxide that can bleach hair pigment; supplementing glycine may slow premature graying.

Why this matters: Connects a specific amino acid to a cosmetic aging concern with a plausible enzymatic mechanism, moving beyond the usual genetic explanation for gray hair.

Background

Hydrogen peroxide is naturally produced by immune cells, but excess can accumulate in hair follicles and oxidize melanin, causing gray hair. Catalase neutralizes it, and its activity depends on glycine.

The speaker explains that catalase, an enzyme that breaks down hydrogen peroxide into water and oxygen, is dependent on glycine. Without adequate glycine, catalase function may decline, allowing hydrogen peroxide to build up and bleach hair from the inside out. This offers a nutritional intervention for hair graying, suggesting that glycine supplementation could support the body's own antioxidant defenses in hair follicles.

There's an enzyme called catalase in your body that helps you break down something called hydrogen peroxide. ... You need glycine for catalase. Catalase is dependent on glycine, or it just can't work.

Also said
“Hydrogen peroxide is made by your immune system and by other cells to help defend itself, and sometimes there's too much hydrogen peroxide, which can actually make your hair lose its pigment and cause graying.”— Explains the graying mechanism that glycine helps counteract.

Glycine supports glucagon to counter insulin and aid weight loss

Glycine not only improves insulin sensitivity but also supports glucagon, the hormone that opposes insulin, promoting fat burning and reducing fatty liver.

Why this matters: Highlights a dual hormonal benefit—enhancing insulin action while simultaneously boosting its counter-regulatory hormone—which is rarely discussed in blood sugar management.

Background

Most blood sugar discussions focus on insulin; glucagon is often overlooked. The speaker notes that glycine helps both, creating a more favorable metabolic balance.

The speaker explains that glycine makes insulin more sensitive, so less is needed to manage blood sugar. Additionally, it supports glucagon, which has opposite effects to insulin: it mobilizes stored energy, promotes fat breakdown, and reduces liver fat. For people with high insulin and weight gain, boosting glucagon can help reverse metabolic dysfunction. This dual action makes glycine a strategic nutrient for metabolic health.

Glycine makes your blood sugar more stable. It also helps make insulin more sensitive... And there's one other thing that's really interesting. There's an opposing hormone to insulin that does the opposite of insulin. It's called glucagon. And glycine supports glucagon.

Also said
“So, those people have too much insulin and they have too much weight gain, it's actually a good thing to support this opposite hormone, glucagon, because it does the reverse actions.”— Explains the practical implication for weight management.

Collagen Powder with Added Vitamin C

Supplement

He advises that any collagen powder should include vitamin C to enhance collagen synthesis.

Vitamin C is a necessary cofactor for the enzymes that cross-link collagen fibers, so taking it alongside collagen improves the body's ability to utilize the amino acids for tissue repair. He doesn't specify a brand, just the feature.

vs alternatives

Compared to plain collagen powders, those with vitamin C may offer better results because vitamin C is often deficient in modern diets and is heat-sensitive.

And if you are taking a collagen powder, make sure it comes with vitamin C, because that allows the collagen to work on our bodies much better.
