1) What is Calcium 500 mg with Vitamin D?

This supplement is based a vitamin and mineral formulation. The formula is based on two active ingredients, which are Calcium and vitamin D3.

Calcium is very important for strong bones and teeth but also brings other important health benefits (helps in weight management, alleviates PMS symptoms). Calcium is commonly lost through nails, hair, sweat and urine on a daily basis. In case of a calcium deficiency, it must be replaced as the body will take the calcium from bones to perform other functions. The main benefits attributed to calcium are in the prevention of osteoporosis (combined with a proper amount of vitamin D), prevention of weight gain (helps the body to burn the fat faster), lowering the risk of cardiovascular disease and reducing symptoms of PMS.

Vitamin D is a fat-soluble vitamin which can be assimilated from certain foods but mostly from dietary supplements. It is also produced endogenously when a person is exposed to sunlight, thus triggering vitamin D synthesis. The vitamin promotes calcium absorption in the gut and maintains normal phosphate and serum calcium levels. This enables normal mineralization of the bone and supports bone growth and remodeling. Doses higher than 4,000 UI per day may cause over absorption of calcium.

These decisions of the Institutes of Medicine may confuse people into thinking they need to take calcium supplements when they do not require supplemental calcium. Not only do bone specialists concluded that most people do not need calcium and vitamin D supplements, but they also warned about the risk of taking too much of these essential nutrients. Unnecessary intake of these nutrients can lead to many health problems including kidney stones and heart disease.

Whether or not you require additional calcium or vitamin D depends on what foods you are eating and how much time you spend in the sunlight. Nevertheless, some studies showed that supplementation with these two nutrients might improve bone mineral density slightly in those individuals who are deficient.

Vitamin D is included in this formula to maximize the absorption of calcium from the digestive tract. This vitamin is naturally produced in our skin when it is exposed to natural sunlight or artificial ultraviolet B radiation. However, you need at least 15 minutes of sunlight exposure daily to ensure the body produces enough of this nutrient. To ensure the absorption of calcium, vitamin D was included in this formula.

The suggested dosage is one tablet two times daily with a meal.

I bought this supplement because I trust this brand and the manufacturer. Also, the price is very good and the tablets are easy to swallow. I feel very good .I can’t say I noticed any side-effects.


This seems to have positive effects on my bones which are pretty fragile. I would definitely recommend this formula.
