Our advanced beauty support formula combines high-potency biotin (5,000 mcg), hydrolyzed keratin peptides, and saw palmetto berry extract — three of the most widely studied nutrients used in hair and nail wellness protocols. Biotin is clinically recognized for supporting normal keratin infrastructure, while hydrolyzed keratin provides the same structural amino acids found in hair itself. Saw palmetto extract is traditionally used in hair density support formulas, making this a targeted daily capsule for stronger-looking hair, nails, and overall beauty support.

Our clinically proven formula includes:

  • Keratin | 400mg — from sustainably sourced vegetarian lamb wool
  • Biotin, vitamin B7 | 5,000 mcg — a clinically studied B-vitamin essential for keratin production and healthy hair growth cycles
  • Saw Palmetto (Serenoa repens) | 200mg — widely researched for supporting scalp health and helping regulate DHT, a hormone associated with hair thinning

“Collagen is the primary structural protein of the dermis, responsible for skin strength, integrity, and elasticity. With age, endogenous collagen production declines, contributing to reduced firmness and the appearance of fine lines. Hydrolyzed collagen peptides may act as bioactive signals that stimulate fibroblast activity and support new collagen synthesis, helping improve skin hydration and elasticity."

The book 'The Collagen Glow' by Sally Kim, with a cover showing various healthy foods and ingredients.

"The Collagen Glow presents a clear, research-grounded approach to collagen and ingestible skincare. Drawing from years of product development, clinical review, and collaboration with labs and flavor scientists, Sally breaks down collagen beyond surface-level beauty claims and explains its role in supporting skin, hair, nails, joints, and overall wellness. It highlights a key industry gap — that many collagen products fail not because of the ingredient itself, but because of poor quality, bad taste, and low daily adherence."

Unexpectedly Creamy collagen powder!

I was kinda skeptical about buying this pouch since I’ve never had banana milk before. However, the reviews were so consistent that I had to try it. My favorite so far has been the vanilla bean until I tried this one. As someone who doesn’t even eat bananas on their own, this collagen creamer is delicious! It literally smells like a banana nut muffin inside. I have tried it with both espresso and matcha, neither have disappointed me yet. I would recommend any “at home” barista to invest in a bag, not only for amazing drinks but for your own personal health as well.

I love it with my coffee

I stopped using coffee creamer and only use 2 tblsps of the banana milk collagen powder. Gives the right amount of sweetness and I can taste the hint of banana milk in my cup. I need it now and I’m waiting on my refill already 🥲
