HelloPharmacist Scorecard of Sceletium 100 by Big Tree

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 supplement contains one active ingredient: sceletium tortuosum, a plant extract. The rest of the capsule is made up of inactive ingredients — microcrystalline cellulose, vegetarian cellulose capsule material, silicon dioxide, and magnesium stearate — that hold the supplement together and make it easy to swallow.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Sceletium's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: mood and stress support.
  • We looked for evidence on: Anxiety, Stress, Depression, Mental well-being, Mood elevation.
  • The closest evidence on file: Sceletium is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Sceletium is rated "Insufficient Reliable Evidence To Rate" for Depression, Stress.

The evidence for sceletium tortuosum isn't established yet in the data we hold. We have insufficient reliable evidence to rate it for anxiety, depression, stress, alcohol use disorder, athletic performance, or weight management.

That doesn't mean it doesn't work — it means we don't have solid proof either way. If you're thinking about it for one of these reasons, talk with your pharmacist about what the research actually shows.

The evidence, ingredient by ingredient Sceletium

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.

Sceletium appears generally well tolerated in small studies, but long-term safety hasn't been studied enough to know how it holds up over time. The most common side effects reported with oral use are anxiety, headache, insomnia, irritability, and nausea.

There are also anecdotal reports of depression, listlessness, elevated blood pressure, and euphoric effects at higher doses — but these come from individual reports rather than formal trials. The safety data advises against use during pregnancy and while breastfeeding.

If you're pregnant, planning to become pregnant, or nursing, this isn't the right choice.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Sceletium.
  • The most serious interaction on file is rated Moderate.
  • For scale: 248 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 your medications against this product if you take CNS depressants (Moderate interaction) — sedating drugs like benzodiazepines, sleep aids, opioids, and some antidepressants. Sceletium can add to their drowsy effects.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Sceletium might interest someone curious about traditional plant remedies, but the evidence for it isn't solid yet. If you take any sedating medications — sleep aids, anti-anxiety drugs, opioids, or certain antidepressants — check with us before starting.

Pregnant and breastfeeding people should avoid it. Talk with your pharmacist about whether it fits your situation.

How can one product interact with so many drugs?

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 sceletium tortuosum, and what is it supposed to do?
Sceletium tortuosum is a plant extract used in traditional medicine. It's marketed for anxiety, depression, stress, and a few other conditions — but we don't have reliable evidence that it works for any of these yet.
Can I take this if I use a sleep medication or anti-anxiety drug?
Not without checking first. Sceletium has sedative properties and could add extra drowsiness or impaired thinking if you combine it with CNS depressants like benzodiazepines, sleep aids, or opioids. Run your specific medications through the checker on this page.

The most common reported side effects from sceletium are anxiety, headache, insomnia, irritability, and nausea. There are also anecdotal reports of headache, depression, listlessness, and elevated blood pressure — though these haven't been studied formally.
Is it safe to take while pregnant or breastfeeding?
No. The safety data advises against use during pregnancy and while breastfeeding. If you're pregnant, planning to become pregnant, or nursing, avoid this product.
How much has sceletium been studied for safety?
It appears generally well tolerated in small studies, but long-term safety data are limited. A thorough evaluation of safety outcomes hasn't been conducted, so we don't have a full picture of how safe it is over time.
