Calcium often causes major health problems
- Many studies have identified many health problems with Calcium supplementation
- Less than 750 mg of Calcium supplement daily - VitaminDWiki has recommended for 7 years
- Some believe that the health problems are due to the spike in blood Calcium from taking the Calcium only once per day - Dr. Greger - March 2018 text and short video
- Perhaps there would be a shorter Calcium spike (and less of a problem) if take Calcium multiple times a day
- Perhaps also less of a problem if the Calcium is plant-based
- Calcium from milk also causes 5+ major health problems 2015 Dr. Greger
- No apparent health problems from processed dairy products (cheese, yogurt, etc)
- Calcium supplements are less of a problem if have adequate Vitamin K
- which keeps Calcium from forming blood-system plaque
- 2.7X increase in rate of Colon polyps in 6-10 years RCT March 2018
- Calcium from food or supplements associated with more deaths (US Cohort of 31,000 people) – April 2019
