Mark’s said it before: He advocates for collagen to become the fourth macronutrient. Collagen supports collagen-based structures in the body, such as fascia, ligaments, tendons, cartilage, skin, nails, and hair, and most of us just don’t get enough of it from meat, dairy, eggs, or plant proteins. Learn more about the important role glycine, the primary amino acid found in collagen protein, and check out our creative culinary ways to include more collagen in your diet.
Reasons to Include Collagen in Your Diet
Most people regard amino acids in one of two ways: essential, meaning our bodies can’t synthesize them, or inessential, meaning our bodies can. There’s also a third category of amino acids: conditionally essential, which become essential in times of illness and heightened stress. One such conditionally essential amino acid is glycine.
A research review published in the journal Oxidative Medicine and Cellular Longevity found that glycine plays a crucial role in controlling epigenetics as well as anti-inflammatory, cryoprotective, and immunomodulatory functions. Researchers found that oral supplementation of glycine in the proper dose can successfully decrease metabolic disorders in those with cardiovascular and inflammatory diseases, diabetes, cancers, and obesity.
Glycine, the primary amino acid in collagen, is synthesized from the amino acid serine. Foods that contain glycine include meat, fish, eggs, and dairy—abundant in the Primal diet, depending on whether you can tolerate eggs and dairy. A typical daily diet synthesizes about 2–3 grams of glycine. But that’s not nearly enough; the human body requires at least 10 grams per day for basic metabolic processes.
An easy way to get more glycine each day is to supplement with collagen. Get a good collagen supplement (Primal Kitchen happens to make a few) and mix it into water, coffee, or tea, and down the hatch it goes. Or, you could get more creative and add collagen to smoothies, stir it into chia pudding or plain yogurt, use it in savory applications such as sauce or soup, or add it to the occasional Primal treat.

Mexican hot chocolate is a rich mug of velvety chocolate, wintry spices, and a hint of heat from cayenne pepper or chili powder. It’s the perfect way to thaw after coming inside from a blustery snow storm, a day on the slopes, or to relish an evening cozied close to a sputtering fireplace.
