4. Boosts Metabolism, Muscle Mass and Energy Output

A boost in collagen may help increase your metabolism by adding lean muscle mass to your frame and helping with the conversion of essential nutrients. One of glycine’s most important roles is helping form muscle tissue by converting glucose into energy that feeds muscle cells. And remember that retaining muscle mass is crucial as you age, since it helps support posture, bone health and burns more calories than fat. When consuming collagen, you can benefit from also consuming vitamin C to ensure your body can convert the collagen into a useable protein. This can begin to restore the source or your energy and vitality.

That’s not all that glycine can do for your metabolism. Research shows glycine also has important roles in both functions of the digestive and central nervous systems, which play big roles in maintaining a healthy, youthful body. Glycine seems to help slow the effects of aging by improving the body’s use of antioxidants and is also used in the process of constructing healthy cells from DNA and RNA.

In addition, it’s been found that arginine boosts the body’s ability to make protein from other amino acids, which is important for repairing muscle tissue, healing wounds, sparing tissue wasting, boosting the metabolism, and aiding in proper growth and development. And glutamine also helps maintain adequate energy by facilitating the synthesizing of many chemicals. This amino acid provides “fuel” to our cells, including carbon and nitrogen.

5. Strengthens Nails, Hair and Teeth

Ever had peeling and splitting nails? Well, a lack of collagen could be to blame. Collagen protein is the building block of your fingernails, hair and teeth. Adding collagen into your diet regimen can help keep your nails strong and possibly reverse signs of hair loss.

A study published in the Journal of Investigative Dermatology found that there’s an “essential relationships between extracellular matrix (ECM) and hair follicle regeneration, suggesting that collagen benefits could include being a potential therapeutic target for hair loss and other skin-related diseases.”

6. Improves Liver Health

If you’re looking to detox your body of harmful substances, improve blood flow and keep your heart young, collagen is extremely helpful. That’s because glycine helps minimize damage your liver experiences when it absorbs foreign substances, toxins or alcohol that shouldn’t be passing through it.

One of the easiest ways to cleanse your liver is with a bone broth fast. I often recommend a three-day bone broth detox to rapidly repair leaky gut. This may help your body rid itself of chemicals and “reset” your gut, improving overall immune function. Studies have even found that glycine can be used to help reduce alcohol-induced liver damage and other forms of acute or chronic liver injury.

7. Protects Cardiovascular Health

The amino acid proline helps your artery walls release fat buildup in the bloodstream, shrinking the fat in the arteries and minimizing fat accumulation. Proline is needed for tissue repair within the joints and arteries, plus it helps control blood pressure. As part of collagen found within joints, it buffers our bodies from the effects of vibration or shock and helps us hold on to valuable cartilage as we get older. It’s also linked with the prevention of arteriosclerosis (hardening of the arteries) since it helps our arteries stay clear of dangerous plaque buildup.

In addition, arginine helps with nitric oxide production, which allows for better vasodilation — meaning the widening of arteries and relaxation of muscle cells and blood vessels that allows for better circulation.
