6 Surprising Ways Collagen Peptides Can Benefit Your Health.

When you think of collagen peptides, you might only think of it in terms of what it can do for your skin. Since the effects of collagen loss on the skin are readily visible (fine lines, sagging skin), it’s the most obvious symptom of collagen depletion. But collagen peptides can do so much more.

Your body and collagen.
No matter who you are, where you live, or what you eat, approximately 30% of your total body makeup is protein. (1) That protein is in the form of a chain of amino acids called collagen. (1) It’s the most abundant protein in your body and responsible for maintaining the health and structure of your bones, muscles, skin, and tendons. 

It’s also true that no matter who you are, where you live, or what you eat, your body’s collagen production will begin to decline at about age 25. And as you age, it continues to slow at the rate of about 1% a year. That may not sound like much, but it becomes a real health challenge—beyond crow’s feet and laugh lines—when you compound it.

As your supply of healthy collagen dwindles, unpleasant things begin to happen in your body. Things you might not think are related to collagen depletion but surprisingly are.

Six important reasons you should consider taking collagen peptides daily:


1. Gain muscle mass, improve weight loss
An amino acid called glycine is an essential component in building and maintaining muscle mass. Collagen (and collagen peptides) contain the glycine your body needs to prevent muscle loss as you age. 

A recent study found that collagen peptide supplementation, combined with resistance training, resulted in a significant muscle mass increase. (2)

As a bonus, it’s also an important component in metabolism. Low glycine levels in the blood are consistently associated with obesity. (3)

2. Improve bone density

Women begin to lose bone density around age 40, and the rate increases after 50 and during menopause. Since our bones' main protein is collagen, a supplement can help you maintain and even increase bone density as you age.

An academic review revealed that “hydrolyzed collagen has a positive therapeutic effect on osteoporosis and osteoarthritis with a potential increase in bone mineral density, and the symptomatic relief of pain.” (4)

Simply put, taking collagen peptides can help you maintain bone density and prevent osteoporosis and osteoarthritis and the pain that goes with it.

3. Heart health

As you age, the buildup of fat in your heart's arteries can begin to block blood flow. This causes stroke, heart attacks, and more (ahem, erectile dysfunction, guys). 

The amino acid proline, abundant in collagen peptides, helps keep the arteries of your heart clear of fat buildup, which helps control your blood pressure. (5) This means it may be time to skip that side order of fries and start supplementing with collagen peptides instead. 

Collagen peptides also contain the amino acid arginine. Arginine helps expand the arteries and improve blood circulation throughout the body.

4. Support better vision

If they aren’t already, it’s likely that once you pass the age of forty, reading glasses are in your future. As you age and collagen breaks down in your skin, it’s also breaking down in other places, including the cornea. (6) (7)

The cornea is your window to the world. It’s what allows light in and the picture you see to come alive in your brain. The cornea is responsible for almost 75% of your eye’s ability to focus. And because it contains collagen (mostly Type 1), as the collagen breaks down, so does the cornea's effectiveness. (6) (7)

5. Collagen peptides can help your liver detoxify

We hate to be the bearers of bad news, but alcohol is one of the most common toxins we ingest. If you have one too many drinks during that Zoom happy hour with your girlfriends tonight, the glycine in collagen peptides can help your liver handle the overload. (8)

6. It’s a joint lubricant

If you’re feeling pretty stiff after what felt like 127 down dogs in yoga class or the extra mile your trainer tricked you into running, collagen depletion may be the reason.

When your joints can’t move as smoothly as they once did, they ache. But you don’t have to live with this (or skip yoga). The proline and glycine in collagen peptides play a significant role in supporting joint health and mobility. (9) Get 20 grams of peptides a day, and your joints won’t even notice an extra mile or two.

Collagen peptides are so much more than a beauty supplement.
To stay healthy, happy, and age-defying in more ways than one, you’d do well to add a daily collagen supplement to your routine.
