Below is general information about the safety of the known ingredients contained in the product Pure L-Serine. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when L-serine is used orally in food amounts. Average dietary consumption of L-serine from combined food and supplemental sources ranges from 3.5-8 grams daily (91405).
POSSIBLY SAFE ...when used orally in medicinal amounts. D-serine 30 mg/kg (about 2 grams) orally daily for 6-16 weeks or 60 mg/kg (about 4 grams) daily for 4 weeks has been used with apparent safety (102202,102206,102214,102215,102237). L-serine up to 400 mg/kg (about 25 grams) daily for up to 1 year has been used with apparent safety (102204,102220,108550).
POSSIBLY UNSAFE ...when used orally in large doses. L-serine in doses greater than 400 mg/kg (about 25 grams) daily has caused reversible side effects including nausea, vomiting, nystagmus, and seizures (102204). D-serine 120 mg/kg (about 8 grams) or more daily might increase the risk of nephrotoxicity (102215).
PREGNANCY AND LACTATION:
Insufficient reliable information available.
Animal research in lactating mice shows that dietary L-serine transfers to milk and increases free L-serine while decreasing glutamic acid, L-alanine, D-alanine, and taurine levels in milk. However, this does not affect serine levels in the offspring (102228). It is unknown what effect supplemental serine may have in humans. Avoid using in amounts greater than those found in food.

General
...Orally, L-serine and D-serine seem to be well tolerated in medicinal doses.
Side effects appear to be dose-dependent.
Most Common Adverse Effects:
Orally: Gastrointestinal distress, including abdominal pain, bloating, dyspepsia, loss of appetite, and nausea.
Serious Adverse Effects (Rare):
Orally: Seizures with high doses of L-serine.
Gastrointestinal ...Orally, D-serine 120 mg/kg (about 8 grams) daily has been reported to cause gastrointestinal distress (102215). L-serine 5-30 grams daily has been reported to cause abdominal pain, dyspepsia, bloating, nausea, and loss of appetite (102204,102220).
Genitourinary ...Orally, D-serine 120 mg/kg (about 8 grams) daily for 4 weeks has been reported to cause proteinuria without glycosuria or creatine elevation. Proteinuria resolved completely after discontinuation of serine (102215).
Hepatic ...Orally, D-serine 120 mg/kg (about 8 grams) daily has been reported to cause asymptomatic transaminitis which resolved after discontinuation of serine (102215).
Immunologic ...Orally, in one very small, exploratory study, patients taking L-serine 400 mg/kg (about 25 grams) daily for one year had a higher rate of localized infections than those taking placebo (102204). Whether ingestion of L-serine caused or increased the risk of these infections is unknown.
Neurologic/CNS ...Orally, D-serine 120 mg/kg (about 8 grams) daily has been reported to cause insomnia after a single dose (102215). Taking L-serine in doses greater than 400 mg/kg (about 25 grams) can cause reversible nystagmus and seizures (102204).
