HelloPharmacist Scorecard of Glycine (Free Form) Powder by Herbadiet

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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: glycine, a simple amino acid. That's it — there are no other active ingredients, and no inactive fillers or binders listed.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: energy production.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Glycine is possibly effective for schizophrenia according to the evidence we hold. For other uses listed — 3-phosphoglycerate dehydrogenase (3-PGDH) deficiency, attention deficit-hyperactivity disorder (ADHD), benign prostatic hyperplasia (BPH), and cystic fibrosis — the evidence is insufficient to rate it.

That doesn't mean it doesn't work; it means the reliable data we have isn't enough yet to say either way.

The evidence, ingredient by ingredient Glycine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Glycine is generally well tolerated at typical doses, but long-term safety data are limited. Mild sedation, irritability, insomnia, fatigue, memory impairment, headache, and sensory impairment have been reported rarely, as have soft stools, nausea, vomiting, upper abdominal discomfort, and dry mouth — though associations with glycine aren't always clear.

Symptoms like sedation and stomach upset resolve quickly if you stop taking it. We don't hold enough reliable safety data to know whether glycine is safe during pregnancy or while breastfeeding.

Talk with your doctor or pharmacist about whether it's right for you in those situations.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Glycine.
  • The most serious interaction on file is rated Moderate.
  • For scale: 1 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check before starting if you take clozapine (Clozaril), an antipsychotic for schizophrenia — glycine may reduce its effectiveness. No other medication interactions are documented in our data for the ingredients we hold.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Glycine is a straightforward single-ingredient supplement that's possibly effective for schizophrenia and generally well tolerated at typical doses, though long-term safety data are limited. If you take clozapine, you'll need to check with your doctor or pharmacist before starting — the supplement may interfere with how well it works.

For any other medications you're on, use the search tool on this page to confirm there's no interaction.

Glycine (Free Form) Powder by Herbadiet: Common Questions

Does Glycine (Free Form) Powder by Herbadiet interact with any medications?
Yes. Based on its ingredients, Glycine (Free Form) Powder has a known interaction with 1 medication. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Glycine (Free Form) Powder contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What does glycine do in the body?
Glycine is a simple amino acid — one of the building blocks your body uses to make proteins and other compounds. In this supplement form, it's taken as a standalone ingredient, though the facts we hold focus mainly on its use in schizophrenia rather than everyday metabolic roles.
Can I take this if I'm pregnant or breastfeeding?
We don't hold enough reliable safety data to know whether glycine is safe during pregnancy or while breastfeeding. Talk with your doctor or pharmacist to weigh the pros and cons for your situation — they know your health details and can give you personalized advice.
What side effects might I notice?
Mild sedation, nausea, vomiting, soft stools, and upper belly discomfort have occurred rarely and clear quickly if you stop taking it. Other symptoms reported include irritability, insomnia, fatigue, headache, and dry mouth, though a clear link to glycine isn't always established.
Is glycine proven to work for ADHD or other conditions?
The evidence we hold is insufficient to rate glycine for ADHD, benign prostatic hyperplasia, cystic fibrosis, or 3-phosphoglycerate dehydrogenase deficiency. It's possibly effective for schizophrenia, but for those other uses, we just don't have reliable data yet.
How long can I safely take this?
Glycine is generally well tolerated at typical doses, but long-term safety data are limited. If you're thinking of taking it for weeks or months, talk with your doctor or pharmacist about what the research says for your specific situation.
