Why this happens
Evening primrose oil is a source of omega-6 fatty acids (specifically gamma-linolenic acid), while vitamin C is a water-soluble antioxidant. They are processed by the body through different pathways and do not interfere with each other's absorption, metabolism, or effectiveness. In fact, some evidence suggests that antioxidants like vitamin C may help protect the fatty acids in evening primrose oil from oxidising (breaking down) in the body.
What you should do
You can continue to take both supplements as directed. As with any supplement, it is best to take them with food to reduce the chance of an upset stomach. If you have any underlying health conditions or are taking prescribed medications (especially blood thinners or epilepsy medication), consult your pharmacist or doctor before starting new supplements.

Patient picks for Drug interactions

Tratamiento y medicación
Can I take Esomeprazole and Trazodone together?
Esomeprazole may reduce the amount of trazodone that your body absorbs. This could potentially make trazodone less effective at treating your symptoms (such as depression or sleep issues). Additionally, both medications can rarely affect the electrical activity of your heart, though this risk is generally low.
