At 5mg per tablet, you're getting **Boron** right in the middle of the 3–6mg range used in clinical research on bone metabolism and hormone support. That's enough to meaningfully reduce urinary calcium loss and support healthy estradiol and testosterone levels, based on the key studies behind boron supplementation. One tablet a day covers it — no stacking multiple capsules to reach a useful dose.

Boron's strongest evidence is for bone mineral retention and hormonal balance, particularly in people with low dietary boron intake (which is common since few foods are rich sources). There's also preliminary research suggesting it supports cognitive alertness, though that evidence is thinner.

The main limitation is that boron research is still relatively sparse compared to major minerals like magnesium or zinc. The evidence is moderate, not deep — so your expectations should match. If you're supplementing for bone or joint support, this pairs well with calcium, vitamin D, and magnesium rather than standing alone.
