The product information advises checking with a specialist before use for pregnant or breastfeeding women and before giving supplements to a child. This is not because the ingredients are known to be harmful; it is simply standard caution for food supplements in these groups, because nutritional needs and safety margins can differ. The same applies if you are already using products aimed at mood or sleep.
For children, the lozenge form can be convenient, but a specialist can help determine whether the amount of glycine and B vitamins is appropriate for a particular child. For pregnant or breastfeeding women, a doctor or pharmacist can assess whether additional B vitamins are needed in the diet. Evalar Glycine Forte is a food supplement, not a medicine, and should not be used as a substitute for professional care or for a varied diet.
If you decide to use the product, keep the packaging so you can show it to a specialist if needed. This makes it easier to give accurate advice about interactions with other supplements or dietary circumstances.
