NCCIH says garlic supplements may increase the risk of bleeding. It says this matters especially before surgery and if you take anticoagulants or aspirin. Tell the prescriber before you start a garlic pill. Food amounts of garlic are not the same as a concentrated supplement.

NIH ODS says vitamin E can inhibit platelet aggregation and oppose vitamin K-dependent clotting factors. Large doses taken with an anticoagulant or an antiplatelet medicine, such as warfarin, can increase bleeding risk, especially if vitamin K intake is low. The fact sheet says the supplemental amount needed for a clinically important effect is unknown, but it is probably more than 400 IU a day. Do not start a high dose on your own.
