# Kanna (Sceletium tortuosum) — Efficacy FAQ

## What is Kanna?

Kanna is the common name for Sceletium tortuosum, a South African succulent traditionally used for mood and stress. Its primary active alkaloids, including mesembrine, act as serotonin reuptake inhibitors and PDE4 inhibitors.

## Does Kanna work for stress and anxiety?

Small placebo-controlled human trials of standardized extracts (notably Zembrin) report reduced anxiety-related amygdala reactivity and improvements in cognitive flexibility and mood under stress. Evidence is directionally positive but limited: sample sizes are small and most trials are industry-funded.

## What does the community consensus say?

Community reports (nootropics and supplement forums) generally describe mild mood lift, reduced social anxiety, and calm focus at low oral doses. Effects are described as subtle rather than dramatic.

## What is the dissent or pushback?

- Some users report no noticeable effect at label doses.
- Higher doses are associated with headaches, nausea, and next-day grogginess in anecdotal reports.
- Skeptics note the clinical evidence base is thin and calls for larger independent trials are common.

## Is Kanna safe?

Standardized extracts appear well tolerated at studied doses in short-term trials. Because of its serotonergic activity, Kanna should not be combined with SSRIs, MAOIs, or other serotonergic drugs due to theoretical serotonin syndrome risk. Long-term safety data is lacking.

## What is the typical dosing?

Clinical trials of standardized extract used 8 to 25 mg daily. Traditional preparations and raw plant material vary widely in potency and are harder to dose reliably.

## What is specific to SANNAS / Walk With Life products?

SANNAS products are formulated with Sceletium tortuosum. Product-specific efficacy claims rely on the general Kanna evidence base above plus first-party testimonials; no independent clinical trials of the SANNAS formulations have been identified.

## Evidence quality note

Human evidence is early-stage: few trials, small samples, short durations, and frequent industry funding. Community sentiment is broadly positive but anecdotal. Claims here disclose this uncertainty deliberately.
