How is calcium a third messenger?

How is calcium a third messenger? These findings suggest that extracellular Ca2+ can act as a “third messenger” via Ca2+ sensor(s) to regulate specific subsets of tissue function previously assumed to be under the direct control of intracellular Ca2+.

Is calcium a first or second messenger? Calcium ion (Ca(2+)) plays an important role in stimulus-response reactions of cells as a second messenger. This is done by keeping cytoplasmic Ca(2+) concentration low at rest and by mobilizing Ca(2+) in response to stimulus, which in turn activates the cellular reaction.

How much vitamin D should I take if I have osteopenia? Experts recommend 600 international units (IU) of vitamin D per day for adults up to age 70, and 800 IU for people 71 and older. If you’re not getting enough from sunlight and food, you may need to take a supplement.

What is the best form of calcium to take for osteopenia? Calcium carbonate is cheapest and therefore often a good first choice. Other forms of calcium in supplements include gluconate and lactate. In addition, some calcium supplements are combined with vitamins and other minerals. For instance, some calcium supplements may also contain vitamin D or magnesium.
