Calcium ascorbate is one such salt of vitamin C. Calcium ascorbate is more easily absorbed into the blood stream than other forms of calcium. Also, this is a neutral salt and hence can be taken in large amounts without any acid upset. Calcium is essential to bone and teeth health and strength.

Calcium deficiencies may result in serious health conditions, such as osteoarthritis. Supplementation is usually recommended to replenish any depleted Calcium reserves and prevent such diseases.

Vitamin C is a water-soluble vitamin, known for its antioxidant properties. This is why it has a large contribution to the immunity function among other benefits.

Calcium Ascorbate Powder is claimed to reduce the severity and the duration of upper respiratory tract infections. It is based on the actions of calcium ascorbate dihydrate and vitamin C.

Calcium ascorbate is a compound made up of calcium and vitamin C. It is commonly used as a preservative in food but is also often included in dietary supplements. It is often taken in supplement form because it allows higher doses of vitamin C and calcium without the unwanted side effects. Calcium ascorbate is less acidic, easier on the digestive tract, therefore, is recommended for those severely ill individuals who are having difficulty absorbing vitamin C and calcium from food. Because it can boost the immune system, it is believed to be effective against colds and fever, reducing both their severity and duration. This, however, may not be true. According to several studies conducted over an extended period, scientists have concluded that vitamin C only slightly reduces the duration of a cold, its effects being unnoticeable most of the time.

Take one level metric teaspoonful 5mL (approx. 3.5g) with water or juice daily, or as directed by your healthcare professional. Although supplementation with calcium ascorbate is safe, overdosing may cause kidney stones and other gastrointestinal problems such as diarrhea or stomach aches.

All other Calcium Ascorbate brands I’ve used had horrible taste. I don’t even feel this one; I take it in a glass of orange juice. I am confident in its benefits, after reading several research studies.
