Why it's on our list

Thorne's berberine is the one practitioners recommend and the top-selling berberine online: two capsules give 1,000 mg — 450 mg of berberine HCl plus 550 mg of Berberine Phytosome (Berbevis), a form bound to sunflower lecithin for better absorption. Berberine is a plant alkaloid taken for everyday metabolic and cardiovascular support.

Questions people ask

Softgel, capsule or tablet — does it matter?

Mostly convenience and swallowing: softgels and capsules are usually smaller and smoother; tablets are often cheaper per serving. The amount of the vitamin per serving is what to compare.

Do vitamins expire?

They carry a best-by date and slowly lose potency after it. Keep the bottle closed, dry and away from heat; a bathroom cabinet is the worst place for it.

Should I take Thorne Berberine 1,000 mg with food?

Follow the label. Fat-soluble vitamins (A, D, E, K) are generally taken with a meal that contains some fat; most multivitamins say 'with food' to be gentler on the stomach.
