Overview
•Magnesium citrate at 400mg daily is within safe limits (UL 350mg from supplements) for healthy adults, but may cause loose stools in sensitive individuals.
•No major drug interactions in this formulation, though high doses can reduce absorption of antibiotics like tetracyclines; space intake by 2 hours.
•Generally safe for pregnancy at recommended doses, but consult healthcare provider as needs vary; avoid exceeding 350mg supplemental magnesium.
•Vegan capsules reduce allergen risks, but rice flour may affect those with grain sensitivities; no common allergens like gluten or soy present.
•Long-term use supports magnesium needs, but monitor for hypermagnesemia in kidney impairment; product quality from NOW is reputable with third-party testing.
•Elderly or children should use lower doses; this 400mg serving may be too high for kids under 12.
