Amy Myers MD Collagen Protein: 6 Things I Noticed After 90 Days

On The Myers Way® Collagen Protein — Daily Use & Gut Formulation:

“This Collagen is one of my absolute favorite supplements and I use it every single day! That's why I custom formulated my own hydrolyzed Collagen powder — sourced from grass-fed, pasture-raised beef, and 100% non-GMO. Collagen is fantastic for those interested in supporting gut barrier function. Collagen is full of amino acids and peptides that help maintain and promote gut lining health. Supporting the gut lining is absolutely paramount for those interested in immune health, thyroid function, and digestive health.”

On Why Collagen Is Central to Leaky Gut and Autoimmune Healing:

“Collagen is essential for a healthy gut lining, strong hair, skin, and nails, connective tissue, and much more. My grass-fed, hydrolyzed Collagen is also rich in conditionally essential amino acids that many of us are lacking in, such as glycine, which supports a healthy mood and restful sleep. The collagen protein powder comes from pasture-raised cows that are grass-fed and never given GMO-feed or antibiotics.”

💊 Amy Myers MD Collagen Protein — At a Glance

① The Post-Meal Digestive Discomfort Reduced by Week Four

I was already taking Leaky Gut Revive and Complete Enzymes, so isolating the collagen's specific contribution was not perfectly clean — but I added the collagen to an otherwise stable routine, and the improvement in post-meal bloating and gut comfort accelerated noticeably within four weeks. The mechanism makes sense: the glycine and proline in hydrolyzed collagen are direct building blocks of the tight junction proteins that maintain intestinal barrier integrity. I had less of the diffuse abdominal discomfort that had been my baseline for years. Not gone, but significantly reduced. By day 60, I could eat meals without the anticipatory awareness of how my gut was going to respond — a mental shift that matters more than it sounds.

② Skin Hydration Changed Around Week Five — Without Changing My Skincare

I didn't start taking this for my skin. The skin changes were a surprise. By week five, the surface texture of my face was noticeably smoother and the under-eye area — which had been consistently dry and slightly crepey — looked more hydrated than it had in months. I had changed nothing in my skincare routine. Type I collagen is the primary structural collagen in skin; its depletion after age 35 is the mechanism behind skin thinning and loss of elasticity. The peptides in hydrolyzed collagen appear to stimulate fibroblast activity — the cells that produce new collagen in the dermis. The timeline I observed (4–6 weeks) is consistent with the clinical study findings for hydrolyzed collagen and skin hydration. It wasn't dramatic. But it was consistent and reproducible across the 90-day period.

③ Hair Texture Improved — Frizz Reduced, Breakage Nearly Stopped

Hair changes with collagen supplementation tend to take longer than skin changes because the hair growth cycle is slower. By week eight, I noticed less breakage when detangling — not dramatically less, but the short broken hairs I was used to seeing on my comb were significantly reduced. By week ten, the mid-shaft frizz that I'd been managing with products was better without any change in my hair care routine. Hair protein is primarily keratin, but collagen provides the amino acids the body uses to synthesize keratin — specifically proline, which the body converts to hydroxyproline as a keratin precursor. This is a slower, more indirect mechanism than the gut or skin benefits, which is why the timeline was later. But at 90 days, the change was real enough that two separate people asked if I'd done something different with my hair.

④ Nails Were Noticeably Harder by Week Six

My nails had been thin and prone to splitting for years — a pattern I'd attributed to my constitution and mostly ignored. By week six, I noticed they were growing longer than usual without breaking. By week eight, the texture was different — harder at the tip, less prone to peeling at the edge. Nails are primarily keratin but require proline and glycine for structural integrity — the same amino acids that dominate the Amy Myers MD collagen profile. I was not expecting this to be the most clearly noticeable change, but it was. The nails are a fast-responding tissue, and the change here was unambiguous and measurable.

⑤ Morning Joint Stiffness in My Hands Improved by Month Three

I'm in my early 40s and had developed the kind of mild morning hand stiffness that makes you pause before typing for the first hour of the day. I hadn't mentioned it to a doctor because it seemed too minor to address. By month three of the collagen, that stiffness was significantly reduced. Not eliminated, but the 20–30 minutes of working through it in the morning had shortened to 5–10 minutes on most days. Type II collagen is more directly linked to joint cartilage health, and the Amy Myers MD Collagen Protein is Type I and III — so this improvement is likely more related to the anti-inflammatory amino acid profile (particularly glycine, which has documented anti-inflammatory properties) than to direct cartilage support. The change was real regardless of mechanism.

⑥ The Unflavored Formula Is Genuinely Invisible in Coffee — Which Changes Daily Compliance

This sounds minor and it's actually the thing that determined whether I took this supplement every day or occasionally. Every collagen supplement I'd tried previously had a taste — usually a slightly chalky, slightly animal-adjacent flavor that made me tolerate rather than enjoy adding it to drinks. The Amy Myers MD Collagen Protein is genuinely tasteless. I've added it to black coffee, green tea, smoothies, and soup without detecting it in any of them. This matters because compliance determines results. A supplement that you take 90% of the time produces approximately 90% of its potential benefit; a supplement that you take inconsistently because it makes your coffee worse produces much less. The tastelessness isn't a premium feature. It's the feature that made the 90-day consistent use possible.

One scoop a day. Gut lining, skin, hair, nails — the amino acids your body stopped making enough of after 35.

• Genuinely tasteless and odorless: Adds to any beverage without altering taste — the single biggest compliance factor for a daily supplement.
• High glycine content (2,470mg per serving): Glycine is the most important amino acid for gut lining repair and is conditionally essential — most adults are chronically deficient. Few collagen products disclose full amino acid profiles; Amy Myers MD does.
• Protocol-integrated formulation: Designed specifically within The Myers Way® gut-healing stack alongside Leaky Gut Revive and probiotics — not a standalone vanity collagen.
• Grass-fed, pasture-raised, non-GMO, antibiotic-free source: Clean supply chain with the sourcing details disclosed — cattle from Brazil, USDA standards, no antibiotics or GMO feed.
• GMP-certified, third-party tested: Consistent quality verification across the Amy Myers MD line.
• Multi-benefit across gut, skin, hair, nails, and joints: At 90 days, all five areas showed measurable change, which is unusual for a single supplement.

• Only Type I and III collagen: The Amy Myers MD Collagen Protein does not contain Type II collagen (primarily found in cartilage, relevant for joint health) or Type V and X. For comprehensive joint support, a multi-type collagen like BioTrust Ageless or Orgain may be more appropriate. For gut and skin health, Type I and III is the right choice.
• Price per gram of collagen is on the higher end: At approximately $65 for 38 servings (11g each), the cost per gram of collagen is ~$0.15. Vital Proteins Collagen Peptides runs about ~$0.10/g and Ancient Nutrition Multi Collagen runs ~$0.08/g. The premium is real — justified in part by the clean supply chain and protocol formulation, but real.
• Results require consistency over weeks, not days: Anyone expecting dramatic changes in the first two weeks will be disappointed. The collagen mechanism is cumulative. The 90-day timeline I observed is realistic, and it requires genuine daily compliance.
• No Type II for dedicated joint support: If joint health is your primary motivation for taking collagen, you'll likely need to supplement with a Type II source separately, or choose a brand with a multi-type collagen formulation.

• If you're following The Myers Way® gut-healing protocol — this collagen is specifically formulated as part of that system, providing the amino acid building blocks for intestinal tight junction repair alongside Leaky Gut Revive and Complete Enzymes.
• If you have leaky gut, food sensitivities, or persistent digestive symptoms — the glycine and proline in Type I and III collagen are critical for gut lining maintenance. This is a more targeted formulation than generic collagen supplements.
• If you want a genuinely tasteless collagen — compliance is the determinant of results. If you've abandoned other collagens because they affected the taste of your coffee or smoothie, this one won't.
• If you're over 35 and noticing changes in skin, hair, and nails — collagen production declines sharply after 35; Type I and III supplementation is the most direct dietary intervention for this.
• If you have an autoimmune condition or thyroid disorder — supporting the gut lining is central to The Myers Way® autoimmune protocol. Collagen is the structural repair component alongside the functional support supplements.

• If joint health is your primary motivation — Type II collagen (found in cartilage) is more directly relevant for joint support. For dedicated joint health, consider a multi-type collagen that includes Type II, or a separate Type II product alongside this one.
• If you're vegetarian or vegan — this is bovine collagen. There are plant-based supplements that support the body's own collagen synthesis (Vitamin C, silica, glycine from plant sources), but they are not equivalent to hydrolyzed bovine collagen peptides.
• If you have a beef allergy — source is bovine collagen peptides exclusively.
• If your budget is under $40/month for supplements — at ~$65 per container for 38 servings (~$1.71/day), this is not the budget collagen option. Ancient Nutrition and Further Food offer comparable collagen profiles at lower price points if the protocol integration is not a priority.

⭐ Final Verdict: Amy Myers MD Collagen Protein Review

Six changes in 90 days of consistent daily use — gut comfort, skin hydration, skin texture, nail strength, hair integrity, and joint stiffness — all in the direction the product claims to work. The mechanism is documented. The amino acid profile is disclosed and specific. The tastelessness is genuine. The A/B test at day 90 (running out, not reordering for a week, noticing the gut changes edge back) confirmed it wasn't coincidence.

The limitations are honest: it's not a multi-type collagen for dedicated joint support, the price is premium, and the results take 4–8 weeks of daily compliance to materialize. If you're not willing to take it every day for at least six weeks without expecting dramatic early changes, this is not the supplement for you.

Rating: 4.6 / 5.0 — For anyone already in The Myers Way® gut-healing protocol or dealing with persistent gut, skin, or hair concerns after 35, this is the collagen I'd recommend. Available at amymyersmd.com.

90 days. One scoop. Gut, skin, hair, nails — from the inside out.
