This forum will allow you to share and review the various vitamins and minerals. Each student will have 1 vitamin and 1 mineral to review and share in this discussion board. All students should have reviewed the various vitamins and minerals with emphasis on the assigned vitamin and mineral. Share the details you discovered with your vitamin and mineral but be sure to discuss the others with your fellow students. As always, the bulk of the points will come from your initial post with additional points from your discussion with a minimum of 3 other students. The more interaction, the more you all will benefit from the information about vitamins and minerals. Don’t forget to identify if the micro-nutrient you are discussing is a vitamin or a mineral. Discuss the functions of the micro-nutrients, food sources and toxicity, deficiency symptoms. The more detail, the better the discussion and of course the points will follow. Enjoy learning about micro-nutrients.

· Around 99% of the calcium in human body is found in the bones and teeth. Calcium continues to strengthen bones until they reach 20-25 years of age, which is when the bone density is high, as part of the aging process that after the bone density declines, calcium still continues to maintain bone and slows down the process of bone density loss.
· Phosphorus is a mineral that makes up 1 % of body’s total weight, which is present in every cell of the body, most of it can be found like for calcium in bones and teeth.
· If people are not getting enough calcium in their diet, the body takes calcium from the bones to ensure normal cell function which can lead to weakened bones, as a person grows older the bone breaks down faster that it rebuilds, which can lead to osteoporosis, which is a risk for people over 50 years of age, which is more common for females after menopaused because of sudden decrease in estrogen.
