HelloPharmacist Scorecard of Cognitex Basics by Life Extension

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
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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Cognitex Basics contains two active ingredients. Alpha-Glyceryl Phosphoryl Choline (alpha-GPC) is a compound that may support memory and cognitive function.

Sharp-PS Green Phosphatidylserine is a phospholipid — a type of fat found in cell membranes — thought to help with brain cell signaling and age-related cognitive decline. The softgel also contains inactive ingredients including safflower oil, gelatin, glycerin, sunflower lecithin, and a few others that help hold the capsule together and preserve freshness.

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 support.
  • We looked for evidence on: Age-related cognitive decline, Cognitive function, Attention deficit-hyperactivity disorder (ADHD), Memory, Mental clarity, Brain health.
  • The strongest evidence on file: Phosphatidylserine is rated "Possibly Effective" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Phosphatidylserine is rated "Insufficient Reliable Evidence To Rate" for Attention deficit-hyperactivity disorder (ADHD), Cognitive function.
  • Also on file: Alpha-gpc is rated "Insufficient Reliable Evidence To Rate" for Cognitive function.

For alpha-GPC, the evidence suggests it's possibly effective for Alzheimer disease, but the data isn't strong enough to rate it for brain tumors, general cognitive function, vascular dementia, or stroke. For Sharp-PS Green Phosphatidylserine, it's possibly effective for age-related cognitive decline and Alzheimer disease, though the evidence is insufficient to rate it for athletic performance, ADHD, general cognitive function, or dementia.

Overall, the strongest evidence is for both ingredients in Alzheimer disease, but neither has been proven to work for broader cognitive support.

The evidence, ingredient by ingredient Alpha-gpc Phosphatidylserine

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both ingredients are generally well tolerated in studies, but long-term safety hasn't been fully established. Alpha-GPC rarely causes dizziness, headache, insomnia, nausea, heartburn, diarrhea, vomiting, or excitation.

A small clinical observation suggests that taking alpha-GPC for at least 2 months may be linked to an increased stroke risk compared with non-use. Phosphatidylserine commonly causes flatulence, gastrointestinal upset, headache, insomnia, and nausea — with higher doses or daily amounts of 200–300 mg being more likely to cause stomach upset, and doses around 600 mg more likely to trigger insomnia.

The safety data for both ingredients during pregnancy and breastfeeding is insufficient; the product's facts recommend avoiding phosphatidylserine during pregnancy and breastfeeding due to lack of safety information.

Side effects, ingredient by ingredient Alpha-gpc Phosphatidylserine

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?
  • 2 of the 2 matched ingredients can interact with medications — Phosphatidylserine, Alpha-gpc.
  • The most serious interaction on file is rated Moderate.
  • For scale: 219 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.

Before taking this product, double-check any anticholinergic drugs (used for overactive bladder, Parkinson's, and certain poisonings) or cholinergic drugs — phosphatidylserine may change how they work. Also check if you use a scopolamine motion sickness patch; alpha-GPC might theoretically reduce its effects.

Use the medication checker on this page for your exact drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Cognitex Basics may be worth considering if you're concerned about memory or cognitive decline, especially in the context of Alzheimer disease, though the evidence is modest. If you take anticholinergic medications, cholinergic drugs, or a scopolamine patch, check with us before you start.

Anyone pregnant or breastfeeding should talk to their doctor or pharmacist — the data on safety isn't there to give a clear answer.

Cognitex Basics by Life Extension: Common Questions

Does Cognitex Basics by Life Extension interact with any medications?
Yes. Based on its ingredients, Cognitex Basics has a known interaction with 219 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cognitex Basics contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 is alpha-GPC, and what's it supposed to do?
Alpha-GPC is a compound your brain naturally makes. It's included because evidence suggests it may help with Alzheimer disease, though we don't have solid proof it works for everyday memory or brain fog. Long-term safety data isn't complete yet.
What about the phosphatidylserine — is that the same stuff in other brain supplements?
Phosphatidylserine (PS) is a fat molecule found in cell membranes, and it shows promise for age-related cognitive decline and Alzheimer disease. This product uses Sharp-PS Green, a plant-based form. Again, evidence is modest, and long-term safety isn't fully known.
Can I take this if I'm pregnant or breastfeeding?
The safety data for both ingredients during pregnancy and breastfeeding isn't there. The facts recommend avoiding phosphatidylserine during pregnancy and breastfeeding unless your doctor directs otherwise. Talk with your doctor or pharmacist about what's right for your situation.
What side effects should I watch for?
Most common are stomach upset, headache, nausea, insomnia, and gas — especially if you take higher doses of the phosphatidylserine. Dizziness and excitation are rare. Alpha-GPC used for 2 months or longer has been rarely linked to stroke in one observation, so don't take that lightly.
Does this product have fillers or other inactive stuff?
Yes — it contains safflower oil, gelatin, glycerin, sunflower lecithin, and a few other inactive ingredients that help form and preserve the softgel capsule. If you have allergies to any of these, check the label or ask us.
Is this product safe to use with my medications?
It depends on what you take. Both ingredients can theoretically interact with certain drug types — anticholinergic drugs, cholinergic drugs, and scopolamine patches. Use the medication checker on this page with your exact medications, and talk to your pharmacist if anything flags.
