Some supplements may have side effects, specifically if taken before surgery or with other medicines. Supplements can cause problems if you suffer from some health conditions.  Most supplements haven’t been tested in children, pregnant women, and other vulnerable groups.  So always do your own due diligence and find a superior tested and approved quality ‘multinutrient’ supplement.
