Which supplements can increase bleed risk when taken with warfarin?

Magnesium, calcium, and potassium
Garlic, ginger, and ginkgo
Vitamin D, C, and B12
Protein powder and creatine

The correct answer is: Garlic, ginger, and ginkgo

Garlic, ginger, and ginkgo have anticoagulant properties which can increase the risk of bleeding when taken with warfarin. The other options, such as magnesium, calcium, and potassium, do not have direct anticoagulant effects and therefore do not increase bleed risk when taken with warfarin. Vitamin D, C, and B12 also do not have anticoagulant effects and therefore do not increase the risk of bleeding. Protein powder and creatine may increase the risk of bleeding indirectly by affecting kidney and liver function, but this is not as significant as the anticoagulant effects of garlic, ginger, and ginkgo. Therefore, option B is the correct option in this question.
