Aloe Leaf
Also known as: Aloe vera, Aloe barbadensis, aloe gel, aloe latex, acemannan, aloe leaf extract, aloe inner leaf gel
Effective Dosage
No established dose from provided studies
What the Science Says
Aloe leaf is a succulent plant whose inner gel contains polysaccharides (including acemannan) used in supplements, beverages, and cosmetics. Lab studies suggest the gel may support wound closure in skin cells, and animal studies hint at possible anti-tumor and antioxidant effects. One small human trial found aloe-containing glyconutrient supplements were well-tolerated but showed no statistically significant improvements in immunity, gut health markers, or psychological well-being compared to placebo.
What It Doesn't Do
Not proven to boost immunity in humans — the one clinical trial found no significant effect. No human evidence it heals wounds when taken orally. Anti-cancer claims are based entirely on animal and lab studies, not human trials. Don't expect it to detox your body or cure digestive disease.

Absorption & Bioavailability
Unknown — no pharmacokinetic data provided in the available studies. The active compound acemannan is a large polysaccharide; absorption and bioavailability in humans are not well characterized from the provided evidence.
Red Flags to Watch For
- Aloin (found in aloe latex and some improperly processed products) has been linked to carcinogenicity in animal studies at high concentrations — check that products use inner leaf gel with low or undetectable aloin levels
- 25% of commercial aloe-based personal care products tested positive for aloins that should be absent — quality control is inconsistent across brands
- Aloin can disrupt gut bacteria and intestinal permeability at certain doses, based on animal and in vitro data
- The only human clinical trial provided showed no statistically significant benefits over placebo for immunity or gut health
- Whole-leaf extracts carry higher risk than inner-leaf gel products due to higher aloin content — labeling is often unclear
