Plant-based Calcium probably better than rock-based

Calcium and Vitamin D category contains

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

Calcium hazards and bioavailability has the following

• All items with Calcium in VitaminDWiki 226 items
• Calcium from food or supplements associated with more deaths (US Cohort of 31,000 people) – April 2019
• More Calcium absorbed with more vitamin D – 6.7% more with 4000 IU – RCT March 2014
• Decrease Calcium and Increase Magnesium when increasing vitamin D
• Calcium supplements proven to NOT reduce fractures, but are proven to INCREASE heart problems – July 2015
• More than 1.4 grams of Calcium increased male death rate by 1.4 X – Sept 2018
• 10,000 IU of Vitamin D is too much if you also take Calcium supplements – RCT Sept 2018
• Calcium Essential to Limit Osteoporosis but Avoid Excess, Say Europeans - Nov 2017
• Hypercalcemia can result from excess Vitamin D (if not reduce Ca or increase water) Oct 2016
• Must balance co-factors when increasing vitamin D 500 Ca, 500 Mg - which has the following concept graph

• More than 800 mg of Calcium increases Cardiovascular events by 85 %– Nov 2011

Amazon (US) has >400 plant-based Calcium supplements

Amazon

Personally, I use the Algae Calcium powder from Amazon I put the powder in a modified salt shaker, and shake in on my morning cereal

Nice 7 year trial of Algae Calcium - 2016

A 7-Year Longitudinal Trial of the Safety and Efficacy of a Vitamin/Mineral Enhanced Plant-Sourced Calcium Supplement
Problems with the study

1. Not a controlled trial
2. Great decrease in participants during the trial
3. Funded by the supplier

But the results are most promising

Plant Calcium has smaller crystals and is 1.5X more bio-available than synthetic Ca - Sept 2021

Comparative characterization study of plant based calcium versus synthetic calcium

Background: Calcium is an essential mineral which supports bone health as well as serves as a major
therapeutic intervention that can prevent and delay the incidence of osteoporosis. Multicellular aquatic
plants like Lithothamnion calcareum are a rich source of plant based calcium.

Aims/Objective: To characterize Plant based calcium and Synthetic calcium sources using sophisticated
analytical techniques.

Material and Methods: Plant based Calcium and Synthetic Calcium sources were subjected to
instrumental analysis such as SEM, ICP-OES and XRD, and comparisons were done followed by
interpretation.

Results and Discussion: In this study, three different instrument techniques like SEM, ICP-OES and XRD were used for the characterization of plant based calcium and synthetic calcium. The results showed that plant based calcium were smaller isotropic crystals as compared to synthetic calcium crystals which were larger and anisotropic. Further, in case of XRD results, plant based calcium is shown to possess two 2θ values, whereas in case of synthetic calcium, it showed a single 2θ value. Further, Magnesium and Boron content were higher in case of plant based calcium as compared to synthetic calcium.

Conclusion: Both Plant based and Synthetic Calcium can be distinguished using SEM, ICP-OES and XRD techniques. Outcomes of this study enlightens the probable reasons for enhanced bioavailability in case of plant based calcium sources as compared to synthetic calcium sources.
