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 Iron Bisglycinate 25 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.
