Glow Cow, Glow Strips & Moo-isturize, explained
Biotin, collagen & skin from the inside
TL;DR
Hair, skin and nails are built from proteins (keratin and collagen) that depend on a few key nutrients. Biotin is essential for keratin, vitamin C is required to make collagen, and zinc, vitamins A, D and E support skin renewal and antioxidant defense. Supplements help most when you're low — and consistency matters more than any single dose.

How it works
- 1
Nutrients
Biotin, vitamin C, zinc and vitamins A, D, E reach skin and hair follicles through the blood.
- 2
Build
Biotin supports keratin production; vitamin C is a cofactor for the enzymes that make collagen.
- 3
Protect
Vitamins C and E neutralize free radicals from UV and pollution.
- 4
Renew
Zinc and vitamin A support normal skin-cell turnover.
- 5
Grow
Hair and nails grow slowly — give it 8–12 weeks.
Biotin: essential, but only if you need it
Biotin (vitamin B7) is a cofactor your body needs to make keratin, the protein in hair and nails. A review of the research found clear benefit for hair and nails in people who are deficient — but true deficiency is uncommon, and evidence in people with normal levels is limited. Glow Cow has 6,000 mcg and Glow Strips 5,000 mcg, both well above daily needs.
Heads up: high-dose biotin can interfere with some blood tests, including thyroid and heart (troponin) tests. Tell your doctor you take it, and stop 2–3 days before blood work.
Collagen & vitamin C
Collagen is the main structural protein in skin. A 2021 systematic review of randomized trials found oral collagen improved skin hydration and elasticity over 8–12 weeks — at doses of 2.5–10 g a day. Your body can't make collagen without vitamin C, which is why Glow Cow pairs collagen with 30 mg of vitamin C.
Honest take: the collagen in Glow Cow (12 mg) and Moo-isturize (100 mg) is far below those studied doses. The vitamins do the work in these formulas; if collagen is your main goal, a powder providing grams is the better tool.
The supporting cast
Vitamin E is an antioxidant that helps protect skin cell membranes. Zinc supports wound healing and a clear complexion, vitamin A supports skin-cell turnover, and vitamin D3 and folate support normal cell growth. Glow Cow covers all of these; Glow Strips focus on biotin, folate and D3; Moo-isturize pairs collagen with vitamin E.
