The Many Wonders of Glycine: Is Collagen Good for You? Is Gelatin Good for You?
My last few posts provide a different perspective around hormones we thought were happy, proteins we thought were anti-inflammatory and supplements we thought helped us sleep better. One amino acid (protein) that’s definitely overlooked but a TRUE hero is glycine.💪
▪️
⅓ of the protein in our body is collagen, which is ⅓ glycine.
▪️
Glycine is INCREDIBLY important for detox - it has the ability to neutralize toxins and protect cells against harmful agents. Food additives like sodium benzoate and compounds from the salicylate family like aspirin MUST be “glycinated” to be detoxed. We also need it to create the antioxidant glutathione, also involved in detoxification.🔄
▪️
Glycine is incredibly important for the formation of collagen, which is a huge part of connective tissue formation like cartilage and bone. Preggo mommas' need for glycine skyrocket.🦴
▪️
Glycine is amazing for our metabolism because it’s “one of the few amino acids that helps spare glucose for energy by improving glycogen storage.” - Staying Healthy with Nutrition⚡
▪️
We need glycine to create hemoglobin. Additionally, it can be used to make creatine, which is used to make DNA and RNA. It also acts as a neurotransmitter in the brain and has a calming effect, making it great for sleep.💤
▪️
This simple protein “has been found to protect against carcinogenesis, inflammation, fibrosis, neurological damage, shock, asthma, and hypertension.” - Dr. Ray Peat🦸
▪️
Glycine is considered “non-essential” because we can make it from choline or other amino acids. But we need B6 and copper to do so, and in a deficiency, glycine becomes essential.💥
▪️
Unfortunately, herbicides like glyphosate cause glycine to be swapped with alanine. This is connected with many health issues, which I’ll talk about.🧴
▪️
The traditional diets eaten by our ancestors ate things like tendons, ligaments, cartilage, skin and connective tissue - very high in glycine - alongside their muscle meats.🍲
▪️
How to get more amazing glycine? Eat:
▪️
Organic
Bone broth
Jello
Hydrolyzed gelatin
Hydrolyzed collagen
Some fish + shellfish
▪️
I like having some bone broth or a smoothie with collagen powder before bed to really get relaxed.💆
