Losartan and Zinc, a caution.

Q: Can I take Losartan and Zinc together?

Possibly, but with caution. Losartan and Zinc have a documented caution-tier interaction. A systematic review of antihypertensive therapy and zinc identified increased urinary zinc loss in losartan-treated patients. The effect is smaller than with sulfhydryl-containing ACE inhibitors but is consistent across studies of ARB therapy. Symptoms of zinc deficiency include altered taste, slow wound healing, hair loss, and reduced immune function.

Q: How does this affect a NutriStack Stack Score?

Caution

What is happening. A systematic review of antihypertensive therapy and zinc identified increased urinary zinc loss in losartan-treated patients. The effect is smaller than with sulfhydryl-containing ACE inhibitors but is consistent across studies of ARB therapy. Symptoms of zinc deficiency include altered taste, slow wound healing, hair loss, and reduced immune function.

Mechanism. AT1 receptor blockade alters renal handling of trace minerals including zinc, contributing to increased urinary zinc excretion. Chronic loss can deplete intracellular zinc pools even when serum looks normal.

Recommendation. If you take losartan long term, a modest zinc supplement (15-30 mg/day) or a multivitamin containing zinc is reasonable, especially if you notice altered taste or recurrent infections. Take zinc with food to limit GI upset.
