Everyone needs calcium. This product should be taken by women, especially those over the age of 20 to protect against the onset of osteoporosis. It is great for those who may be predisposed to bone loss or those who do not have an adequate intake of dairy products. It is necessary for growth and may be of special necessity for adolescents and pregnant females. Younger women need more calcium to build up the strength of their bones. Pregnant and lactating women need extra calcium to foster the healthy growth of new cells and of breast milk. Finally, those with poor cardiovascular health have been found to have low levels of calcium intake. Studies have confirmed the positive impact of calcium supplementation on heart health.

Calcium plays a pivotal role within the body's cells, regulating both the storage and breakdown of fat. The more calcium there is in a fat cell, the more fat it will burn. Consuming dairy products has been shown to thwart weight gain.

PMS is an undesirable influence on physical and psychological peace of mind. Recent studies have found that over 70 percent of relationships are affected in some way by PMS. Supplementation with calcium can significantly reduce PMS symptoms. Ovarian hormones affect calcium, magnesium and vitamin D metabolism. Estrogen regulates calcium metabolism, intestinal calcium absorption and parathyroid gene expression and secretion, triggering fluctuations across the menstrual cycle. As a woman is menstruating, her hormones are "all over the place". Clinical trials in women with PMS have found that calcium supplementation effectively alleviates the majority of mood and somatic symptoms.

Studies have shown that the most calcium absorption occurs in the early teen years.

Everyone's water is different; some tap water has a higher concentration of minerals, and the pH level of water differs depending on geographic location and the quality of the tap water, which can lead to inconsistencies with the saturation point of a solution. To ensure that our solutions reach the point of saturation, regardless of the pH or mineral levels in water, we have maximised the formulation amounts so that every serving of Isotonix Calcium Plus contains the correct amount of calcium. The residue left in the cup is due to over-saturation which is common in tap water with a higher pH level or a higher mineral content.
