heyhey, I want to bring some calcium managers like boron, K2MK4, magnesium to your attention for osteoporosis Sufficient magnesium is needed for vitamin D and thiamine (B1) to become bioactive Sadly, adequate levels are not in many diets and often supplements used have low absorption levels. Krispin shares her valuable magnesium information in the link below. Boron is often overlooked and the 3 mg mentioned in the article is, I believe, a maintenance level. Health issues like osteoporisis, fibromyalgia and arthritis require up to 20 mg a day from food and supplements.. Always consult your health care professional before using any supplement.
