caroline2,
I am taking strontium citrate for help with bone density. It must be taken on empty stomach and no calcium within past 2-3 hours. Am looking into brands such as Vitalitus, peaCURE, Mirica (non-micronized, has PEA + luteolin), Nootropics (available on Amazon), and Lake Avenue Nutrition (an i-herb exclusive brand, however it seems to have several fillers). Difficult to know which is best. Major cost differences, but don't want to decide by cost alone. Cheapest could be poor quality.
