This study was probaby paid for by the manufacturer.
Most Calcium supplements result in poor health, especially when vitamin D is increased
A plant-based supplement with many Vitamin D cofactors is probably better than just Calcium supplements
Bone Mineral Density INCREASED by 7% in 7 years

The Magnesium, Vit D, Vit K, and Boron also help build bones,
and MAY reduce other problems
no consensus on Strontium

Note: Trial used 2 capsules taken twice a day - at a cost of $2.32
Competing products using very similar ingredients are about 1/4 that price

OBJECTIVES:
The objective of this study was to examine the safety and efficacy of a vitamin-mineral enhanced plant-sourced calcium AlgaeCal calcium (AC) in female consumers who had taken the supplement from 1 to 7 years.

METHODS:
Consumers who had completed at least one dual-energy x-ray absorptiometry (DEXA) bone mineral density (BMD) scan (N = 172) and/or blood chemistry test (N = 30) and purchased AC from 1 to 7 years were contacted and offered complimentary repeat tests. Safety and efficacy were examined by annualized changes in a 45-measurement blood chemistry panel and changes in BMD.

RESULTS:
No adverse effects or safety concerns were found in any of the annualized within-group annualized changes in the 45 blood chemistries or in between-group changes in a similar control group (n = 5070) who completed the same measurements. With regard to BMD, consistent and statistically significant within-group increases were found for the 7-year study period and when compared to expected BMD changes in 3 large databases or the combination (N = 25,885) of the 3 databases. Data from this study suggest that AC supplement was associated with a significant annualized and linear increase in BMD of 1.04% per year, 7.3% over the 7-year study period. These results stand in marked contrast to normative or expected changes of -0.4%/y from 3 different databases or in a combination of all 3 databases (N = 16,289).

CONCLUSIONS:
No evidence was found in cardiovascular risk as measured by adverse changes in blood lipids, nor was any evidence found of a diminished efficacy over the 7-year study period because gains in BMD were consistent and linear over the 7-year study period, averaging 1.04% per year over the 7-year study. The results are also consistent with earlier short-term studies suggesting that this supplement can facilitate significant increases in total body BMD in contrast to studies suggesting that calcium supplements can only slow down age-related declines in BMD.
