HelloPharmacist Scorecard of Alpha GPC 600 mg by Nutricost

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

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: Alpha-GPC 600 mg per capsule. Alpha-GPC is a compound that occurs naturally in the brain and helps support cell membranes and nerve function.

The capsule also contains inactive ingredients — rice flour, hypromellose, stearic acid, magnesium stearate, and silicon dioxide — which are fillers and binders.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Alpha-gpc's overall clinical evidence instead.

Moderate

Some clinical evidence supports Alpha-gpc for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Alzheimer disease — rated "Possibly Effective" (Natural Medicines).

The evidence for Alpha-GPC is mixed. It's rated possibly effective for Alzheimer disease based on available research.

For brain tumor, cognitive function, vascular dementia, and stroke, the evidence isn't established enough in our data to rate it either way. If you're considering it for one of those other conditions, talk with your doctor about what the current evidence shows for your situation.

The evidence, ingredient by ingredient Alpha-gpc

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.

Alpha-GPC is generally well tolerated in studies, though long-term safety hasn't been fully established. A small number of people have reported dizziness, headache, insomnia, excitation, nausea, heartburn, diarrhea, or vomiting.

Rarely, oral use has been associated with stroke, particularly when taken for at least two months — the risk was higher in long-term users compared to non-users or short-term users. Because safety data is limited, it's best to take it only if your doctor recommends it.

Side effects, ingredient by ingredient Alpha-gpc

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Alpha-gpc.
  • The most serious interaction on file is rated Minor.
  • For scale: 16 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.

If you use the scopolamine patch (Transderm Scop) for motion sickness or nausea, check with your doctor or pharmacist before taking Alpha-GPC — it may decrease how well the patch works.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Only minor medication interactions are documented, and safety information is well characterized.

Alpha-GPC may be worth considering if you're dealing with Alzheimer disease and your doctor thinks it could help. If you take the motion-sickness patch (Transderm Scop), be aware it might interfere with the patch's effects.

Because long-term safety isn't fully known and stroke has been rarely reported, especially with longer use, talk with your doctor or pharmacist before starting — they can weigh the benefit against the risks for your situation.

Scopolamine (Transderm Scop)

Theoretically, alpha-GPC might decrease the effects of scopolamine.
A small clinical study shows that alpha-GPC can partially counteract the attention and memory impairment effects caused by scopolamine given intramuscularly. Whether alpha-GPC can decrease the beneficial anti-motion sickness effects of the scopolamine patch (Transderm Scop) is unclear.

Alpha GPC 600 mg by Nutricost: Common Questions

Does Alpha GPC 600 mg by Nutricost interact with any medications?
Yes. Based on its ingredients, Alpha GPC 600 mg has a known interaction with 16 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Alpha GPC 600 mg 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 Alpha-GPC do?
Alpha-GPC is a compound that supports cell membranes and nerve function in the brain. It's rated possibly effective for Alzheimer disease, but the evidence for other conditions like stroke, vascular dementia, or general brain function isn't clear enough to rate yet.
Has anyone had side effects from Alpha-GPC?
Most people tolerate it well, but a small number have reported dizziness, headache, insomnia, excitation, nausea, heartburn, diarrhea, or vomiting. Rarely, stroke has been reported, especially in people who took it for two months or longer.
Is it safe to take long-term?
Long-term safety hasn't been fully established in studies. Because stroke risk has been reported in some long-term users, it's important to take it only if your doctor recommends it and to stay in touch with them about how you're doing.
Can I take this while pregnant or breastfeeding?
We don't have safety information on file for pregnancy or breastfeeding. Talk with your doctor or pharmacist — they can help you decide whether it's right for your situation.
Will this work for memory and thinking?
The evidence for general cognitive function and memory isn't established enough in our data to say either way. If that's what you're hoping it'll help with, ask your doctor what the current research shows.
