evidence for boron
Our honest take
One capsule gives 3 mg of boron as sodium borate, a modest amount that sits well under the UK safe upper level of 9.6 mg a day. Boron is not a proven essential nutrient, it has no authorised health claims, and the research on bones, joints and hormones is small and inconsistent, so most people do not need it. If you do want it, this is a clean label: just sodium borate, inulin and a plant capsule.
- You want a vegan boron capsule and understand the evidence is limited
- You are expecting a noticeable effect on hormones, joints or bones
- You are pregnant, breastfeeding or trying to conceive
- You already take a multivitamin or bone formula containing boron
The science
Boron· evidence: Insufficient
Boron is a trace element found in fruit, vegetables, nuts, pulses, wine and coffee. Most adults take in about 1 to 3 mg a day from food. It has no set daily requirement and no NRV, because it has not been shown to be essential for humans.
Small studies have looked at boron and bone, joints and hormone levels, but the evidence is limited and inconsistent. Claims that boron raises testosterone come from a handful of tiny short studies. There are no authorised health claims for boron.
Most people do not need a boron supplement.
Typical dose: Supplements usually give 3 to 10 mg a day.
Safety: The UK Expert Group on Vitamins and Minerals set a safe upper level of 9.6 mg a day from all sources, and EFSA's upper limit is 10 mg a day for adults. Higher doses may harm fertility and development, so avoid in pregnancy and breastfeeding. Keep away from children.
