Health Concerns BioStrong offers 680 mg of strontium, supplied as strontium carbonate, along with 5 mg of BioPerine black pepper fruit extract. While the elemental strontium dose is substantial, the carbonate form is sometimes seen as less bioavailable than citrate, though BioPerine is often included to support nutrient absorption.
The product's price per serving is on the higher side compared to many other strontium supplements, and it has a relatively small number of customer reviews. This suggests it might be a more niche option, potentially appealing to those specifically seeking a strontium carbonate with an absorption enhancer.
