HelloPharmacist Scorecard of Glycine 3000 mg Capsules by BulkSupplements.com
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 one active ingredient: glycine, an amino acid your body makes naturally and uses in protein synthesis and nervous system function. Each capsule delivers 3,000 mg.
The capsule itself is made from bovine gelatin, an inactive ingredient that holds the glycine together.
Does it work?
Moderate evidence
Glycine is possibly effective for schizophrenia based on the evidence we have on file. For other uses listed—including 3-phosphoglycerate dehydrogenase (3-PGDH) deficiency, attention deficit-hyperactivity disorder (ADHD), benign prostatic hyperplasia (enlarged prostate, or BPH), and cystic fibrosis—there isn't enough reliable evidence yet to say whether it works.
How safe is it?
Well-documented data
Glycine is generally well tolerated at typical doses, though long-term safety data are limited. Mild sedation has occurred rarely and resolves quickly if you stop taking it.
A small number of users have reported irritability, insomnia, fatigue, memory issues, headache, and sensory changes, though it's unclear whether glycine caused them. Rarely, some people experience soft stools, nausea, vomiting, stomach discomfort, or dry mouth—these also resolve quickly with discontinuation.
There isn't enough reliable safety data to know whether glycine is safe during pregnancy or while breastfeeding. Talk with your doctor or pharmacist before use if you're pregnant, planning to become pregnant, or nursing.
Meds to double-check
Moderate interaction found
Check with your pharmacist or doctor before taking this if you're on clozapine (Clozaril). Glycine may decrease how well this antipsychotic works and could worsen schizophrenia symptoms.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Glycine may help with schizophrenia if your doctor approves it. If you take clozapine, don't start this product without checking first—the two together may work against each other.
For other uses, the evidence isn't established yet. Chat with your pharmacist before you begin, especially if you're pregnant, breastfeeding, or on any medications.
