People with kidney or thyroid conditions, pregnant or breastfeeding women, and anyone taking diuretics, NSAIDs or other lithium products should talk to a doctor first.

Our take on the Life Extension Lithium Capsules 1000 Mcg

Life Extension Lithium is a low-dose lithium supplement: 1000 mcg (1 mg) per capsule, 100 capsules per bottle, gluten free. Lithium at this trace dose is marketed for mood and brain support rather than the far higher prescription doses used for psychiatric treatment. It suits people curious about low-dose lithium who want a single-ingredient capsule from an established supplement brand. Compared with prescription lithium carbonate, the dose is a small fraction, so it is not a substitute for medical treatment.
