What the Science Says

Kanna is a succulent plant from South Africa (Sceletium tortuosum) used for centuries by indigenous Khoikhoi and San peoples to reduce stress, elevate mood, and suppress hunger. Its active compounds, particularly mesembrine, are thought to act as serotonin reuptake inhibitors and PDE4 inhibitors, which may explain mood-lifting and calming effects. While traditional use is well-documented, rigorous human clinical trials are largely absent, so the full scope of its effects in modern supplement doses remains unclear.

What It Doesn't Do

Not proven to treat depression or anxiety disorders — don't replace prescribed medication with it. No solid evidence it reliably suppresses appetite or aids weight loss. Not a substitute for therapy or lifestyle changes. Marketing claims about 'cognitive enhancement' are far ahead of the actual science.

Red Flags to Watch For

  • May interact with antidepressants (SSRIs, MAOIs) due to serotonergic activity — potentially dangerous combination
  • No standardized dosing exists; potency varies widely between products
  • Limited safety data for long-term use or use during pregnancy and breastfeeding
  • Some products may be adulterated or mislabeled given the 1,000+ registered supplement products with minimal regulatory oversight
