Berberine has blood thinning properties and i was already on xarelto. I'd been plagued with irritable bowel syndrome symptoms for several months. Berbercap is not quite as effective, but still packs a wallop.

Thorne is a grandly high quality product! It works and it works fast. I am a loyal thorne research customer and i love their products but berberine is not for everyone. Works great. I love that this product is readily available from amazon.

Nih has no conclusive evidence on the efficacy of either type of rhodiola herbal supplements.
