The product description sets out the restrictions as follows:
- Teenagers – the supplement is intended for adults and children over 14; it is not given to younger children, and for teenagers it is best to agree its use with a doctor, as the need for magnesium and B6 during a period of active growth differs from that of adults.
- Pregnant women – pregnancy is listed among the contraindications, and the supplement is not taken during this time.
- Breastfeeding women – breastfeeding is also listed among the contraindications.
The supplement is also not used in cases of kidney failure or individual intolerance to any of the ingredients. If you have a chronic condition or are taking any medicines, consult a doctor before you start taking it: magnesium and B6 can interact with a number of medicines.
The supplement is positioned as a food supplement for adults during periods of increased strain, not as a universal product for all ages and conditions.
