Gelatin is largely composed of the amino acids glycine and proline, which many people don’t consume in adequate amounts as they are found in the bones, fibrous tissues and organs of animals and as a population, we don’t consume these parts as much anymore. These amino acids are needed not only for proper skin, hair and nail growth, but for optimal immune function and weight regulation!
Glycine, which makes up about 1/3 of the amino acids in gelatin powder is anti-inflammatory and evidence is finding that it can help speed wound healing. Glycine in gelatin can also help improve sleep ease and quality.
Good for joints and can help joint recovery
Can help tighten loose skin (like the kind you get after having four babies in five years…)
Can improve digestion since it naturally binds to water and helps food move more easily though the digestive tract
Rumored to help improve cellulite
Great source of dietary collagen (side note: collagen is too large to be absorbed by the skin, so those skin creams are pretty useless… get it internally and use coconut oil for lotion!)
Source of protein (though not a spectacular one) but its specific amino acids can help build muscle.
For a long time, gelatin’s therapeutic effect in arthritis was assumed to result from its use in repairing the cartilage or other connective tissues around joints, simply because those tissues contain so much collagen. Some of the consumed gelatin does get incorporated into the joint cartilage, but that is a slow process, and the relief of pain and inflammation is likely to be almost immediate, resembling the anti-inflammatory effect of cortisol or aspirin.
