“Hydrolyzed collagen” means that collagen has undergone “hydrolysis”.
Hydrolysis breaks up the amino acids in collagen, making their chains much shorter. These shorter chains are called “peptides” (44).
Collagen peptides are much more bioavailable to your body and easier on your digestive system. They’re pretty much odorless, tasteless, and dissolve easily in any liquid because of their tiny size.
Can I Get Collagen From My Diet Alone?
Because the collagen found in food is extremely hard to break down (because it hasn’t been hydrolyzed), it’s nearly impossible to get enough collagen from food alone.
That’s why I recommend taking a grass-fed collagen supplement daily to ensure your collagen levels stay replenished.
Are There Foods That Can Boost My Collagen Production?
Fun Fact: Your body requires other nutrients in order for collagen supplements to work their magic.
With that in mind, here’s a list of nutrients and nutrient-rich foods that promote your body’s ability to make new collagen:
- Vitamin A: Largely found in orange fruits and veggies like carrots, cantaloupe, and sweet potatoes, foods rich in vitamin A help by restoring damaged collagen.
- Vitamin C: This antioxidant-rich vitamin, found in foods like bell peppers, broccoli, and citrus fruits, is extremely important for your body to produce collagen. Vitamin C also helps by neutralizing free radicals, preventing them from breaking down collagen in your body.
- Dark leafy greens: Their high chlorophyll content (what makes them green) promotes collagen synthesis, and their high amount of skin-loving antioxidants helps protect you from free radicals (45).
- Lycopene: Red veggies boost your collagen production because they’re full of lycopene—think red peppers, tomatoes, and beets. They also protect you from the effects of sun damage, or overexposure to ultraviolet rays. Too much exposure to ultraviolet rays is a big factor in the depletion of collagen in your body.
- Berries: All types of berries work by both detoxifying your body of skin-damaging free radicals and boosting collagen levels.
- Sulfur: This mineral is excellent at synthesizing collagen. Garlic is one of the best sources of sulfur you can find, but there are other sources like eggs, onions, cabbage, and broccoli. Your body actually can’t produce collagen without sulfur, so be sure to get enough of this mineral.
- Garlic: In addition to sulfur, garlic also contains taurine and lipoic acid, which help rebuild damaged collagen fibers.
- Bone Broth: Full of glycine and proline, as well as growth factors called glycosaminoglycans, bone broth enhances immunity, gut health, and weight loss while reducing inflammation and joint pain.
Is Collagen Vegan?
It depends on where it’s sourced from.
The majority of collagen supplements are derived from animal sources like pigs, beef, chicken, or fish.
Vegan collagen, on the other hand, is made from genetically modified yeast and bacteria (46). If you’re wanting to skip the GMOs, collagen can also be found in the following foods:
- Legumes: black beans, kidney beans (47)
- Nuts: especially pistachio, peanut, and cashew (48)
- Seeds: especially pumpkin, squash, sunflower, and chia
- Soy products: tempeh, tofu, and soy protein (49)
