This is What a 20g Megadose of Collagen Every Day Did for Me (within days)

DeLauer explains that collagen peptides provide the amino acid building blocks and signaling peptides, but the body cannot assemble functional collagen without vitamin C. He points out that this is a common mistake: people take collagen but fail to support the synthesis step. Vitamin C is simple and cheap, and he says 'without it, it doesn't work.' He recommended this specifically for skin improvement, where the goal is to rebuild the dermal matrix.

DeLauer describes the mechanism in detail: the timing is crucial because collagen needs to be enzymatically digested into small peptides first. The 30–60 minute window ensures that when you start training, these bioactive peptides are circulating and can be actively pulled into load-bearing tissues. He alluded to an older jump rope study where the mechanical bounce literally drew collagen peptides into the Achilles tendon. He contrasts this with the idea of just taking collagen anytime, noting that strategic pre-workout dosing maximizes the repair signal in the exact tissues that are about to be stressed. This protocol is particularly valuable for older athletes who find that stiffness and prior injuries limit workout intensity.

DeLauer describes his own gut struggles—IBS as a child, recent parasite—and how collagen dramatically reduced bloating and the uncomfortable 'need to go but can't' feeling. He emphasizes that collagen works through its specific amino acid profile, not just as generic protein. He acknowledges that direct clinical trials on collagen for gut barrier function are lacking, but the mechanistic case from glycine and glutamine research is compelling. Taking it in the morning ensures these gut-healing amino acids reach the small intestine quickly and at high concentration, setting the gut up for resilience throughout the day.

DeLauer highlights that his hair became more resilient on collagen, but he knows the science: collagen can't do its job alone. He explains that while collagen provides the raw signals and building blocks, biotin and silica are needed to assemble the collagen into the complex, organized matrices that give hair and nails their strength. He recommends getting these from diet or supplements. This is a common omission—many people take collagen for hair/nails without the necessary co-factors. He cites the 2017 study on nail growth with collagen, implying that the participants likely had sufficient co-factors, but for those not getting enough, results may be suboptimal.

DeLauer notes there is recent evidence distinguishing connective tissue protein synthesis from muscle protein synthesis. He suggests that athletes often neglect the connective tissue component, leading to chronic soreness and injury risk. He himself alternated taking collagen pre- and post-workout, but states that for those focused on recovery, having collagen with your main protein source (like a post-workout whey shake) is effective. He also touches on glycine's role in creatine synthesis and glucose metabolism, suggesting metabolic benefits that further support recovery.

DeLauer found this effect surprising because he was simultaneously taking ipamorelin, a ghrelin agonist that increases hunger. Yet, his appetite was controlled. He cites a study comparing gelatin (cooked collagen) to casein, finding gelatin more satiating despite its lower essential amino acid content. He recommends using this trick strategically before the day's largest meal to naturally reduce calorie intake and avoid energy crashes. The dose of 10–15g is lower than his experimental 20g, suggesting a moderate pre-meal dose is sufficient for appetite modulation without overloading on collagen calories.

DeLauer stresses that most people think only of calcium for bones, but the collagen matrix is equally critical. He uses the concrete-and-rebar analogy to explain that without collagen, bone is brittle. He references a study where postmenopausal women taking collagen peptides for a year improved bone mineral density markers. By adding D3 and K2, you cover both the absorption and the proper destination of calcium, preventing it from ending up in arteries. This stack is a comprehensive, low-cost approach to bone health.

DeLauer designed his 30-day protocol specifically to test a high end of dosing—20g daily. He noticed meaningful results within days to weeks across multiple systems. He suggests that while standard doses (2.5–5g) may be sufficient for maintenance, a megadose approach may be necessary for therapeutic or rapid improvement goals. He mentions knowing people who go up to 40–50g without issues. However, he cautions that collagen lacks tryptophan and is not a substitute for complete protein, so you must still consume high-quality protein sources to support muscle health. He advises starting at 10g and ramping up to avoid digestive discomfort.

Thomas DeLauer, approaching 40, had noticed facial fat loss and loss of elasticity. He started 20g collagen daily, and after about 10 days observed that his skin looked 'plumper' and had a better bounce. He attributes this to collagen peptides providing glycine, proline, and hydroxyproline, which stimulate fibroblasts to produce new collagen and hyaluronic acid — the molecules responsible for skin fullness and hydration. This signaling role is key: the peptides don't just supply building blocks, they activate the body's own synthesis machinery. He cites a 2014 double-blind study in *Skin Pharmacology and Physiology* showing improved elasticity and hydration after 8 weeks, yet he saw changes in half that time. To maximize this benefit, he strongly recommends pairing collagen with vitamin C, a critical co-factor for collagen synthesis (without it, cross-linking fails).

DeLauer spends a lot of time in high-heat sauna, which made his hair 'super brittle' and he could literally break it off. He notes that for many people, thinning hair and brittle nails are markers of nutrient deficiencies. After increasing collagen, 'that didn't happen anymore. It was more resilient.' He references a 2017 study in the *Journal of Cosmetic Dermatology* showing that daily collagen peptides significantly increased nail growth and reduced breakage. The same principles apply to hair follicles. Crucially, he stresses that collagen alone isn't enough; you need biotin and silica as co-factors to organize the collagen into the stable matrices that support hair and nails. Without these, the building blocks may not be effectively utilized.

DeLauer clarifies that he later took ipamorelin (a ghrelin agonist and GH secretagogue) which also accelerates recovery, but he noticed improvements before starting it. The key benefit was a reduction in that 'perpetually sore' feeling that prevents older athletes from training as hard or as often. He explains that collagen's amino acid profile, especially glycine, plays a role in creatine synthesis and glucose metabolism—helpful given his past insulin resistance. He also notes that working out breaks down connective tissue, not just muscle. By pairing collagen with a high-quality whey protein, you get two distinct types of protein synthesis: collagen for tendons and ligaments, whey for muscle. He alternated taking collagen pre- or post-workout but suggests that if recovery is the primary goal, take it alongside your main protein source to support both pathways simultaneously.

DeLauer was using ipamorelin, a growth-hormone secretagogue that is also a ghrelin receptor agonist, making him hungrier. Despite this, he found collagen caused notable satiety and reduced cravings. He references a study where gelatin (a cooked form of collagen) was more satiating than casein, the most satiating dairy protein. He hypothesizes that the high glycine content might modulate appetite signals to the brain, and the gelatinous attribute may affect gut hormones that control hunger. His protocol: take 10–15g collagen in water about an hour before the largest meal to preload the system, potentially reducing intake and helping with energy balance.

DeLauer acknowledges he cannot personally confirm this benefit because he didn't get a DEXA scan. However, he wants to highlight the evidence: a study in *Nutrients* showed postmenopausal women taking collagen peptides for 12 months had a marked increase in bone mineral density markers. He uses the analogy of concrete without rebar—without the collagen scaffolding, minerals alone can't maintain bone integrity. He recommends pairing collagen with vitamin D3 (to ensure calcium absorption) and vitamin K2 (to direct calcium into bones and away from arteries). This trio creates a comprehensive bone-support stack.
