Aspartic acid, also known as aspartate, is an α-amino acid that is used in the biosynthesis of proteins. Similar to all other amino acids it contains an amino group and a carboxylic acid. Though it’s considered safe, some are convinced it has potentially dangerous health effects.
What Is D-Aspartic Acid?
D-Aspartic Acid is a White or white crystalline powder with the molecular formula (C4H7NO2). Primarily used as a nutraceutical, it is considered to be a nutrition enhancer and can be found in many nutritional supplements or as an additive in many foods.
Possible Side Effects of D-Aspartic Acid
D-Aspartic Acid is generally considered a safe ingredient. The side effects may:
- Mood Swings
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. D-Aspartic Acid is considered safe by FDA.
Special Populations Precaution
There is a lot of concern about diet and nutrition for these population, like Newborns, children, pregnant, sensitive to D-Aspartic Acid populations. Better consult to your doctor if you would like to intake D-Aspartic Acid.
