When pharmaceuticals become "vitamin robbers", their long-term use can result in serious health problems. B vitamins in particular frequently fall victim to drug treatment. But vital minerals such as magnesium can also be washed out of the body in increasing amounts by some medications.
If this results in the gradual development of a deficiency, taking this medication may even develop into a dangerous boomerang effect and counteract the actual goal of the treatment.
In practice, little attention is paid to vitamin and mineral deficits which are caused by medications. For this reason, the Society for Biofactors has published an overview here of the active ingredients and groups of active ingredients which can impair the vitamin and mineral balance in the body when used over a prolonged period.
