HelloPharmacist Scorecard of L-Serine 2000 mg by Double Wood Supplements
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains a single active ingredient: L-serine, a naturally occurring amino acid. The capsules also hold two inactive ingredients — hypromellose (a capsule binder) and rice flour (a filler).
Does it work?
Not established
L-serine is possibly effective for schizophrenia based on the evidence we have on file. For Alzheimer disease, amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease), back pain, post-traumatic stress disorder (PTSD), and cognitive function, the current evidence is insufficient to rate how well it works — meaning we don't have enough reliable data yet to say one way or the other.
How safe is it?
Well-documented data
L-serine appears to be well tolerated at medicinal doses, though side effects tend to depend on how much you take. The most common ones are gastrointestinal — stomach pain, bloating, indigestion, loss of appetite, and nausea.
At very high doses (over about 25 grams daily), seizures have been reported rarely, along with a reversible eye movement disorder (nystagmus). There isn't enough safety data to recommend this supplement during pregnancy, so it's best avoided unless your doctor advises otherwise.
Safety during breastfeeding hasn't been studied, so avoid it unless your doctor directs you to take it. While serine from food is generally considered low-risk, long-term safety of the supplement form is not well established.
Meds to double-check
No known interactions
No interactions are documented for L-serine in our data. Still, if you're on any medications and want to be thorough, use the interaction checker below to search your specific drugs.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
L-serine may be worth considering if you're interested in schizophrenia support, though talk with your doctor first about whether it fits your situation. If you're pregnant, nursing, or taking any medications, check with your doctor or pharmacist before starting.
No interactions are documented with medications we have data for, but that's not a blanket safety assurance — your own provider should review your full picture.
