Stops hair loss for me

When I switch to other selenium brands I notice hair shedding, but returning to this product stops it. Years ago a clinician suggested selenium for antidepressant-related hair loss; brand choice matters. I avoid products with yeast, so this yeast-free formula suits me and I’ve used it on and off for years.

Using with iodine protocol — positive follow-up

I began taking this selenium alongside an iodine regimen to support breast health and planned to report results later. After six months on the iodine protocol with supporting nutrients (selenium, magnesium, vitamin C) I had a follow-up mammogram: breast density and calcifications reduced, and a previously concerning area shrank. I’ve moved to a maintenance iodine dose and now take selenium three times a week. The tablets are small, low in taste, and feel high quality—I keep returning to this brand. I used an online guide for iodine supplementation to structure the protocol.

Performed as expected

No reactions for sensitive stomach

I don’t see dramatic changes, but I also have no adverse reactions. Works well for someone with multiple food sensitivities.
