This product is generally selected by adults. The source specifically advises asking a doctor or pharmacist if you are pregnant or breastfeeding, if you are choosing the supplement for a child, or if you are taking other products that also contain magnesium or vitamin B6. Children usually have different nutritional needs, so it is better to use a product designed for their age.
It is also sensible for anyone with a chronic condition, especially concerns related to the kidneys, or anyone on regular medication to ask a specialist before starting a food supplement. A doctor or pharmacist can help you check whether this product fits with your particular situation, and whether the combined amount of magnesium and B6 from all sources is appropriate for you.
This product is not intended to diagnose, treat, or prevent any disease. It is a food supplement for people who want to complement their diet, and it should not replace prescribed treatment. If you have any doubts, the best step is to ask a specialist before using it.
