Can I take St john's wort and Vitamin c together?

Why this happens

Vitamin C (ascorbic acid) and St John's Wort (Hypericum perforatum) are processed by the body through different pathways. Vitamin C is water-soluble and does not interfere with the liver enzymes (specifically the CYP450 system) that St John's Wort is known to affect. Furthermore, they do not have overlapping effects on the body's systems that would cause a conflict.

You can continue to take both supplements as directed. However, always inform your doctor or pharmacist about all supplements you are taking, as St John's Wort interacts with many prescription medicines, such as the contraceptive pill, blood thinners, and antidepressants.
