L-Serine is an amino acid, which is produced by fermentation and turned into white crystals. It is commonly used as nutritional enhancer found in nutritional sport drinks. Though it’s considered safe, some are convinced it has potentially dangerous health effects.
What Is L-Serine?
L-Serine is a white crystalline powder. Secondly, L-Serine is also widely applied in food. Few lysine could help to promote cerebrum growth, body strengthening and intelligence improvement. Thirdly, L-Serine could work in feed. This product could enhance organism resistance to disease promote growth, strengthen animals appetite and then increase the output capacity of lean meat. What’s more, L-Serine could be used as the biochemical reagents, food additives, accessorysubstance (eg. skin nutrition additives in cosmetic) and the natural moisturizing agent in some cosmetics and skin care products.
Possible Side Effects of L-Serine
Although L-Serine generally regarded as a very safe and effective supplement, there can be some minor side effects. The side effects may: Tiredness, Anxiety, Chronic Fatigue, Neurotoxicity, Depression.
GRAS Affirmation: Yes
Generally recognized as safe (GRAS) is an American Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. L-Serine is considered safe.
Special Populations Precaution
There is a lot of concern about diet and nutrition for these population, like Newborns, children, pregnant, sensitive to L-Serine populations. Better consult to your doctor if you would like to intake L-Serine.
