What to know
Aloe products do not all contain the same plant material. Inner-leaf gel, latex, whole-leaf material, extracts, and powders differ. Acemannan is associated with the inner gel. Processing and standardization affect how an aloe ingredient is described on a finished-product label. When you compare an acemannan product, check the plant part, amount per serving, other ingredients, and directions. Do not assume research on isolated acemannan proves the same result for a finished commercial formula.
