HelloPharmacist Scorecard of Glycine Sticks 3 grams by Metabolic Maintenance
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, a simple amino acid. Each stick delivers 3 grams of glycine in powder form, with no inactive fillers or other ingredients listed.
Does it work?
Moderate evidence
Glycine is rated possibly effective for schizophrenia. For other conditions listed—3-phosphoglycerate dehydrogenase deficiency, ADHD, benign prostatic hyperplasia, and cystic fibrosis—the evidence we hold is insufficient to rate whether it works.
How safe is it?
Well-documented data
Glycine is generally well tolerated at typical doses, but long-term safety data are limited. A small number of trial participants reported mild sedation, though symptoms cleared quickly after stopping it.
Rarely, people have also reported irritability, insomnia, fatigue, memory problems, headache, and sensory changes, though whether glycine caused these isn't clear. Digestive side effects like soft stools, nausea, vomiting, and upper stomach discomfort have occurred rarely and resolved quickly; dry mouth has also been reported.
There isn't enough reliable safety data on glycine in pregnancy or while breastfeeding, so it's best avoided in these situations unless your doctor approves.
Meds to double-check
Moderate interaction found
If you take clozapine (Clozaril) for schizophrenia, check with your doctor or pharmacist before starting this product. Glycine may decrease how well clozapine works.
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 symptoms, though the evidence is still developing and long-term safety isn't fully established. If you take clozapine, talk with your doctor or pharmacist before trying this product—the interaction could affect how well your medication works.
For anyone else considering glycine, a conversation with your own healthcare provider about whether it fits your situation is a good idea.
