What Is Collagen (And Why Does Your Skin, Hair & Nails Love It)?

Collagen is the most important protein in your body. It's what keeps your skin firm, your hair strong, and your nails from breaking.

As we get older—especially after age 25—our bodies make less collagen. This leads to fine lines, thinning hair, and weaker nails. That’s where collagen supplements come in. They give your body the support it needs to stay youthful, glowing, and strong.

But with so many products out there, which one should you choose?

Let’s break down of some of Proto-col’s top collagen supplements and whether they’re best for skin, hair, or nails.

Beauty Collagen

Best for: Skin & Nails

This is your all-in-one beauty booster. It’s packed with 5,000mg of VERISOL® collagen peptides—a clinically studied type of collagen known to:

  • Reduce wrinkles
  • Improve skin elasticity
  • Strengthen nails

It also contains vitamin C, zinc, and biotin—key nutrients your body needs to build healthy skin and nails.

 If you're starting to notice dullness, fine lines, or peeling nails—this one’s your go-to.

Marine Beauty Collagen

Best for: Skin (especially if you're pescatarian)

Prefer a fish-based collagen? This marine option delivers 8,000mg of hydrolysed collagen from wild caught white fish. It’s light, clean, and easy to absorb.

It also includes hyaluronic acid for deep hydration, plus vitamins B6, C and E to support glowing skin from within.

Perfect for anyone wanting radiant skin with a marine-friendly formula.

Hair Support

Best for: Hair Strength & Growth

Formulated with clinically proven Anagain™ Nu, this advanced blend of key amino acids (cysteine, methionine, arginine, lysine, glutamine, and proline) works at the root level to:

  • Stimulate keratin production for stronger, fuller strands
  • Reduce hair shedding and improve density in just 8 weeks*
  • Maintain your natural hair pigment with PABA, a powerful anti-greying ingredient
  • Support scalp health for optimal hair growth

While it doesn’t contain collagen, it works hand-in-hand with collagen supplements to give you fuller, healthier hair.
