At 3 mg, this **Boron** supplement matches the most common dose used in clinical research, so you get a full studied amount in one capsule. Boron is a trace mineral your body uses to help retain calcium and magnesium and to support steroid hormone activity, the basis for its use in bone and hormone routines. The 3 mg here sits at the bottom of the 3 to 6 mg studied range.

Keep expectations grounded. The evidence is preliminary, mostly small, older trials, several in people eating low-boron diets, showing modest shifts in markers like calcium retention and free testosterone. Boron is part of these pathways, but it is not a proven testosterone booster, and most diets already supply some from fruit, nuts, and vegetables. The label also includes 25 mg of riboflavin. This is a low-cost, well-dosed option if you want targeted bone or hormone support and eat little produce.
