Ingredients - For 60 & 120 Calcium For Kids Capsules. Progressive Complete Calcium for Kids contains the finest specialty and active ingredients including: Ester C – Vitamin C assists in the production of collagen, one of the key components of bone. This patented form of calcium ascorbate offers greater absorption and retention than all other forms of vitamin C. It has a neutral pH (non-acidic) and will have a longer lifespan in your child’s system. Vitamin D3 – Also known as the sunshine vitamin, this nutrient is essential for the proper uptake of calcium. Vitamin D3 assists in the passage of calcium from the intestinal tract into the bloodstream. Magnesium – This mineral assists in the absorption of calcium, regulates the transfer of minerals through the cell membrane, aids in the formation of bone and increases the biochemical activity of vitamin D. Mineral Citrates – Only a small percentage of the minerals that we normally consume are actually absorbed and utilized by our bodies. However, minerals in citrate form have a much higher absorption rate and are transported into our cells far more efficiently. Green Food and Vegetable Concentrates – This comprehensive combination of highly alkaline, nutrient-rich green foods includes broccoli, alfalfa, kelp, spinach, and wakame. They improve blood pH and detoxify impurities normally found in a child’s diet. These vegetables themselves are a source of highly absorbable botanical calcium. Digestive Support – These include the plant-based digestive enzymes bromelain and papain, as well as Bioperine®, the patented piperine extract that improves the passage of nutrients across the intestinal wall and into the blood stream, thus increasing the absorption of the entire formula. EFA Complex – The essential fatty acids found in flax seed and sunflower oil (CLA) play a very important role in both bone formation and maintenance. As well, EFAs are beneficial for improving focus, concentration and sharpening mental acuity.
