Can taking supplements cause a headache?
No predictable or plausible explanation exists for headaches resulting from use of a multivitamin product. Typically, other confounding factors (such as stress, anxiety, infection or food triggers) are a more likely cause. Occasionally, a drastic change in lifestyle, diet, nutritional supplementation or exercise may lead to transient headaches, but these tend to subside as the body adjusts to the change(s) being made.
If you experience headaches that seem to be linked to the nutritional products, there is no recommendation other than to discontinue and restart slowly to find a tolerable level.
Additional information on headaches can be found at the National Headache Foundation’s Homepage. If you experience recurring severe headaches, please consult a medical professional, as these may be indicative of an underlying medical condition.
