Aloe Vera Inner Leaf Extract (200:1)

Botanicalgut soothingModerate dose evidence

Also known as: Aloe barbadensis, aloe inner leaf, aloe vera gel powder, decolorized aloe, acemannan

Add to a formula

Aloe vera inner leaf extract is the dried, decolorized gel of Aloe barbadensis, supplied as a 200:1 concentrate so that 50 to 200 mg represents 10 to 40 g of fresh gel. Its main constituents are polysaccharides, notably acemannan. It is used in digestive comfort, skin, and glucose-support formulas. Meta-analyses have examined oral aloe in irritable bowel and glycemic studies. Inner-leaf material must be processed to remove aloin and other anthraquinones; non-decolorized whole-leaf extract is a different, laxative material.

Research summary

Polysaccharides studied for soothing and immune-modulating effects on the gut lining.

Dosage

Daily amounts, of extract.

Lowest studiedTypical rangeHighest studiedUpper limit
50 mg50–200 mg

50 to 200 mg of 200:1 inner-leaf powder (equivalent to 10 to 40 g gel) daily. Require a decolorized, aloin-free specification (typically under 10 ppm aloin). Non-decolorized whole-leaf aloe is on the California Proposition 65 list, so documentation of the inner-leaf, decolorized process matters.

Standardization: 200:1 inner-leaf concentrate; aloin ≤10 ppm; often ≥10% polysaccharides

Source material: inner leaf gel, freeze-dried or spray-dried
