L-Cysteine E920 is an essential amino acid protein supplement used in nutraceutical, nutritional supplement, and food additive applications. Though L-Cysteine E920 is considered safe, some are convinced it has potentially dangerous health effects.
What Is L-Cysteine E920?
L-Cysteine E920 is an amino acid that is used in food processing. This product appears as white crystals or crystalline powder with a strong acidic taste. L-Cysteine is used for bread fermentation and is used to prevent ageing in the food industry.
Possible Side Effects of L-Cysteine E920
Although L-Cysteine E920 generally regarded as a very safe and effective supplement, there can be some minor side effects. The side effects may:
- upset stomach, nausea, vomiting, diarrhea, persistent stomach cramps, body aches, headache, and general gastrointestinal discomfort.

L-Cysteine is considered safe.
Suggested Dosage
NA.
Special Populations Precaution
There is a lot of concern about diet and nutrition for these population, like Newborns, children, pregnant, sensitive to L-Cysteine populations. Better consult to your doctor if you would like to intake L-Cysteine.
