Holistic Health from Easy-to-Digest Collagen

But, with the right collagen peptides, you get a multitude of benefits in a few scoops. Key is to find a product with all the 5 major sources of collagen.

We found clear standouts – and many that you should avoid at all costs. Ready to discover which is right for you?

The Older You Get, The More Collagen You Need

Here’s the unfortunate biological reality though: the older you get, the less collagen your body produces. By your mid-20s it starts to decline. By 40, it’s down 25% and, by 60, it will decrease by more than 50%.

So, as your body produces less collagen each day that goes by, your skin becomes less firm, your hair thins, your joints, bones and muscles lose strength, and your digestive system function decreases.

Collagen Peptides – The Simple Way to Give Your Body the Vital Collagen it Needs

So, research makes it crystal clear why collagen is vital to whole-body health. But getting enough in your body from food alone is extremely difficult. That’s why health practitioners around the world are recommending collagen peptides.

Just one look at the incredible benefits makes it easy to see why collagen peptides are considered a revitalizing, “whole body” supplement.

Help glowing skin health and elasticity, minimizing fine lines and wrinkles

Boost and balance gut health and support appetite control

Promote healthy, strong hair and nails

Encourage lean muscle and faster metabolism

Strengthen immune function and reliance

What To Avoid:

Artificial Sweeteners & Added Sugar

These nasty additions can cause all kinds of damage and cause weight gain.

"Natural" Flavors

The ugly truth is, most “natural flavors” are chemically made and disguised as healthy by marketers.

Artifical Preservatives

Added to extend shelf life, artificial preservatives fill your body with unwanted, harmful chemicals.

Soy-based Fillers

Used to bulk up products, soy fillers can negatively impact important vitamins and minerals in your body.

Must Haves

Choose only grass-fed, pasture-raised bovine or sustainably-sourced seafood collagen.

Purity & Quality

Hydrolyzed collagen peptides mean the amino acids have been broken down for super easy digestion and absorption.

Hydrolysed Collagen Peptides

A Full Spectrum Collagen Combination (Type I & III)

The best combination for overall health benefits that make up 90% of the collagen in your body.

Look for at least 8g of collagen per serve with no additives or flavors!

Potency & Strength

Flavour & Mixability

Most of the Off-the-shelf collagen supplements tend to taste bad and do not mix well. Try to find a collagen you'll be glad to consume every morning!.
