HelloPharmacist Scorecard of Alpha GPC Capsules 150 mg by Nootropics Depot

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 11, 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 (150 mg per capsule), a compound that delivers choline to your brain. The capsules also contain inactive ingredients — microcrystalline cellulose, silicon dioxide, tricalcium phosphate, and cellulose — which are fillers and binders that make up the capsule.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Memory and cognitive function support.
  • We looked for evidence on: Alzheimer disease, Cognitive function, Vascular dementia, Age-related cognitive decline, Memory, Learning.
  • The strongest evidence on file: Alpha-gpc is rated "Possibly Effective" for Alzheimer disease (Natural Medicines).
  • Also on file: Alpha-gpc is rated "Insufficient Reliable Evidence To Rate" for Cognitive function, Vascular dementia.

Alpha-GPC is possibly effective for Alzheimer disease based on the evidence we hold. For cognitive function, vascular dementia, stroke, and brain tumors, the evidence isn't strong enough yet for us to rate it reliably.

If you're thinking about this for one of those conditions, talk with your doctor about what the current research suggests 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, but long-term safety hasn't been fully established. In rare cases, people taking it orally have reported dizziness, headache, insomnia, and excitation.

Very rarely, it's been associated with diarrhea, heartburn, nausea, and vomiting. Importantly, oral use for at least 2 months has been rarely linked to an elevated risk of stroke compared with non-users or shorter-term users.

We don't have enough safety information on alpha-GPC in pregnancy and breastfeeding — talk with your doctor or pharmacist before use if you're pregnant, planning to become pregnant, or breastfeeding.

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, check with your pharmacist — alpha-GPC may reduce its effectiveness. Altogether, these interactions span 16 individual medications.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

Alpha-GPC may be worth considering if you're interested in Alzheimer disease support and want to explore the evidence. If you use a scopolamine motion sickness patch or take any regular medications, check them first on this page.

Long-term safety data is limited, and the rare stroke association warrants a conversation with your pharmacist or doctor before you start.

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 Capsules 150 mg by Nootropics Depot: Common Questions

Does Alpha GPC Capsules 150 mg by Nootropics Depot interact with any medications?
Yes. Based on its ingredients, Alpha GPC Capsules 150 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 Capsules 150 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.
Does alpha-GPC actually work for memory or cognitive function?
The evidence is mixed. It's possibly effective for Alzheimer disease, but for general cognitive function there isn't enough reliable evidence yet to say how well it works. If you have a specific condition in mind, ask your pharmacist what the current research supports.
What are the common side effects?
Alpha-GPC is generally well tolerated. Rarely, people report dizziness, headache, insomnia, or minor digestive upset like nausea or heartburn. Serious side effects are uncommon, but stroke has been very rarely reported with long-term use.
Is it safe to take if I'm pregnant or breastfeeding?
We don't have enough safety information to know either way. Talk with your doctor or pharmacist before taking this if you're pregnant, planning to become pregnant, or breastfeeding — they can give you personalized advice based on your situation.
Can I take this with my motion sickness patch?
Alpha-GPC may reduce how well the scopolamine patch (Transderm Scop) works for motion sickness. If you use one, check with your pharmacist before adding this supplement.
How long does it take to see a benefit?
The facts we have don't specify how quickly you might notice effects. That's a good question for your pharmacist, who can discuss realistic timelines based on the research and why you're taking it.
