HelloPharmacist Scorecard of Stem Cell by Life Extension GeroProtect

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 3 active ingredients.
  • “Presveratrol Proprietary Blend” is a proprietary blend — the label gives one combined amount (378 mg) without saying how much of each component you get.

Life Extension GeroProtect Stem Cell has three active ingredients. Japanese Knotweed extract is included in the formula — we have interaction data on file for it but no documented effects on common drugs.

The other two actives are Livinol Kokum extract and Passion Fruit extract, and we don't hold detailed monograph information for either of those. The product also contains several inactive ingredients — microcrystalline cellulose, cyclodextrin, vegetable cellulose, rice concentrate, and silica — which are fillers and capsule materials with no active role.

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: promotes healthy cellular renewal.
  • We looked for evidence on: cellular health, cellular aging, senescence.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The data we have covers Japanese Knotweed extract only, and for that ingredient the evidence isn't established. We rate it as having insufficient reliable evidence for gingivitis.

We don't hold effectiveness information for Livinol Kokum extract or Passion Fruit extract, so we can't speak to what those might do.

The evidence, ingredient by ingredient Knotweed

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Japanese Knotweed extract appears to be reasonably tolerated in the short term, but human safety data are limited and it can cause digestive side effects in some people. The safety information for Livinol Kokum extract and Passion Fruit extract isn't on file, so we can't tell you what to expect from those.

For pregnancy and breastfeeding: Japanese Knotweed extract isn't recommended during pregnancy because some of its compounds may affect the uterus, and there isn't enough information to recommend it while breastfeeding. We don't have pregnancy or breastfeeding data for the other two actives, so if you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist before taking this product.

Side effects, ingredient by ingredient Knotweed

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented for the ingredients we could check. That said, we couldn't verify two of the three actives, so use the medication search below to check your exact drugs before you begin.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.

This product might interest you if you're looking into stem cell support, but the evidence for its ingredients is limited. If you're pregnant, planning pregnancy, or breastfeeding, check with your pharmacist or doctor first — Japanese Knotweed extract has specific cautions for those times.

It's always smart to run your medications through the tool on this page before you start.

Stem Cell by Life Extension GeroProtect: Common Questions

Does Stem Cell by Life Extension GeroProtect interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Stem Cell. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Stem Cell contains 3 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.
Can I take this while I'm pregnant?
Not recommended. Japanese Knotweed extract in this product can affect the uterus, and there isn't enough safety data on the other ingredients either. Talk with your doctor or pharmacist before use if you're pregnant or planning pregnancy.
Can I take this while breastfeeding?
There isn't enough safety information for any of the three active ingredients during breastfeeding. Check with your pharmacist or doctor for personalized advice.
Will this cause digestive side effects?
Japanese Knotweed extract can cause digestive upset in some people, though it's generally tolerated short-term. We don't have side-effect data for the other two actives.
Does this actually work?
We only have effectiveness data for Japanese Knotweed extract, and the evidence isn't established — it's rated as insufficient for gingivitis. We don't have data on whether the other two ingredients work for their intended purpose.
