In the fresh Aloe vera plant there are more than 200 various compounds.

Some of these compounds have strong laxative impacts.

Other substances might trigger allergic reactions.

Properly extracted, the recovery compounds of Aloe vera are without these laxative effects and without the allergic reactions that can occur with fresh Aloe vera gel and other poorly prepared Aloe supplements.

Vera-mannan™ includes only the extracted beta-mannans and beta-glucans which have been shown to possess the recovery advantages associated with Aloe vera with not one of the possible adverse effects.

These pure beta compounds are in the carbohydrate group.

Just protein compounds, not carbs, are known to cause allergic reactions.

For that reason an allergic reaction to these beta extracts is probably unknown.
