The Active Ingredient Is: Boron (Sodium Borate)
Boron is a trace element that features in everyday mineral metabolism and hormonal balance, helping essential bodily processes. This form is sold as sodium borate and is suitable for vegetarians and vegans.
This ingredient helps with enzyme activity and mineral transport to support overall health.
What Does Boron Do?
Boron supports bone upkeep, improves the utilisation of calcium, magnesium and vitamin D, and contributes to hormonal balance. This combination lines up with recognised roles in mineral metabolism and endocrine health.
Dr. Nielsen from the National Institutes of Health found that boron may improve bone markers and calcium retention, reinforcing its potential role in maintaining bone-related mineral balance.
