Question

Quizplus · Accepted Answer

Calcium gluconate contains the lowest percentage of calcium, with only 9% elemental calcium. This may make it a good choice for individuals who need lower levels of calcium supplementation, or who have a higher risk of side effects from other forms of calcium supplements. However, for most people, it may be more beneficial to choose a supplement with higher percentages of elemental calcium, such as calcium citrate or calcium carbonate.
