We wouldn’t expect any at all for most people, unless you have an allergy / sensitivity to one of the ingredients (which isn’t expected but, in theory, is possible with any food).

You should always check with your doctor, especially if on medication. It appears most doctors advise not to use turmeric if you take Warfarin or have gallstones.

If you are concerned, when first starting the supplement, begin taking just 1 capsule a day for a few days, and then build up the dose gradually from there.  For most adults, in general, we recommend building up to 4 capsules per day (2 in the morning, with food, 2 in the evening, with food), but obviously check with your doctor if you wish.
