Fortify Your Calcium Intake

5 Salts

Unlike most calcium products that rely on just one or two basic forms, this advanced blend features five distinct calcium salts, each selected for their superior bioavailability and complementary health benefits.

375 mg

of calcium in one serving of Isotonix® Calcium Plus. While leafy greens are healthy, supplements can ensure consistent and bioavailable calcium intake — especially for those with increased needs.

Charge Up with Calcium

Calcium is a cornerstone of everyday health, and Isotonix® Calcium Plus is designed to deliver it better. Our advanced formula blends multiple bioavailable calcium salts in an isotonic form — helping it remain in a charged, ready-to-absorb state as it moves through your body. The result? Faster uptake, better utilization and stronger support for the life you live today and tomorrow. It's calcium, elevated.

Frequently asked Questions

If I am not an elderly woman, why should I take a calcium supplement?
Calcium plays a huge role in regulating many major bodily processes with implications that extend far beyond the age factor. Other than elderly women who may be susceptible to bone loss, younger women, pregnant and lactating women, and men should take a calcium supplement. Younger women need more calcium to build up the strength of their bones. Pregnant and lactating women need extra calcium needs to foster the healthy growth of new cells and of breast milk.
I have heard calcium is great for PMS? How so?
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. So PMS impacts nearly everyone, including men! Supplementation with calcium can reduce PMS symptoms. In a study conducted by the US Department of Agriculture's Human Nutrition Research Center, it was found that women on a high calcium diet had decreased irritability, cramping and bloating associated with PMS. 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 menstruates, her hormones are "all over the place." Clinical trials in women with PMS have found that calcium supplementation helps reduce mood and somatic symptoms associated with PMS.
If we only absorb 300 to 400 mg of calcium at a time, why does one serving contain 750 mg?
There are 750 mg of calcium in 2 capfuls of Isotonix Calcium Plus. Therefore, one capful equals 375 mg of calcium. For this reason, it is recommended to only take one capful at a time: one in the morning and one in the evening.
Why is Isotonix Calcium Plus better than other calcium products?
It is better because of the Isotonix delivery system. The secret of the isotonic process is probably now becoming clear! When an isotonic substance enters the body, it will be absorbed into the bloodstream rapidly. With isotonic fluids, little nutritive value is lost making the absorption of nutrients highly efficient. There is nothing artificial about it. An isotonic fluid is nature's own nutrient delivery system.
Why is there left over powder in the cup after mixing with water?
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 maximized 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.
What is the best way to store this product?
Keep Isotonix stored in a dry, cool place. If Isotonix are stored in the kitchen, keep them away from the stove, sink, heat-generating appliances or window ledges. If you live in a very humid area, you may store Isotonix products in the refrigerator – but not in the fruit and vegetables area.
