Ashwagandha (Withania somnifera) is an herb traditionally used extensively in Ayurveda. This supplement contains a root extract, standardized to 2.5% withanolides. The extract form ensures consistent quality.
The vitamin C in this supplement comes from magnesium ascorbate, a compound of magnesium and ascorbic acid. This form is gentle on the stomach and is often used in complexes where multiple nutrients are combined.
Bonusan Stress B Complex Pro contains folate instead of regular folic acid. 5-MTHF-glucosamine was chosen, under the brand name Quatrefolic®. This form is more common in supplements containing active B-vitamins.
It contains methylcobalamin and adenosylcobalamin, both natural forms of B12. These are often combined in B-complex formulas to provide broad supplementation. Cyanocobalamin, a synthetic form, is not used in this product.
Inositol is often classified as a pseudovitamin because it is chemically related to B-vitamins, although it is not an official vitamin. It is found in foods such as fruits, beans, and grains, and is regularly added to supplements with multiple B-vitamins.
