Support your body's need to grow and stay strong.
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.
375mg
of calcium in one serving.

Calcium
Calcium is essential for building and maintaining strong bones. Isotonix Calcium Plus Powder Drink provides the body with an optimal blend of calcium, vitamin D3, manganese, magnesium and vitamin C in an efficient isotonic solution that is readily absorbed by the body. Isotonic supplements bear chemical resemblance to your own tears and plasma, so your body absorbs the nutrients rapidly and more effectively.

Stronger Bones and Better Health
Many calcium supplements exist in the marketplace, but only Market Hong Kong's Isotonix Calcium Plus Powder Drink delivers a potent package of calcium and complementary nutrients through an isotonic system of delivery. This translates into a lower cost overall when compared to calcium supplements in pill form by making more of the active ingredients available to the body. Don't be misled by ingredient amounts. What really counts is the amount of active ingredients that your body can ultimately use.

Frequently Asked Questions
Why should I take calcium?
Everyone needs calcium. Practically no one ingests enough calcium in their daily diet. Besides being helpful in supporting and maintaining bone integrity, calcium serves a dynamic role as a mineral. It's very important in supporting the activity of many bodily enzymes and maintainingproper fluid balance. Calcium also promotes the normal contraction of muscle and skeletal health.
I'm 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 to foster the growth of healthy new cells and for the production of breast milk. Finally, those with poor cardiovascular health have been found to have low levels of calcium intake.
What is the suggested age to begin taking Isotonix Calcium Plus Powder Drink?
Isotonix Calcium Plus Powder Drink is recommended for all adults age 18 or older
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. An isotonic fluid is nature's own nutrient delivery system.
Why is there a sandy residue left 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 Powder Drink 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.
Does this product have “No Detectable GMOs”?
This product is tested with no GMO detected. This product’s raw material may contain genetically modified materials/ingredients, but the finished product does not contain any transgenic DNA fragment or transgenic proteins.
Is Isotonix Calcium Plus Powder Drink safe?
Isotonix Calcium Plus Powder Drink is safe and free of harmful agents. The product is made in the United States in FDA-inspected facilities using Good Manufacturing Practices. Customers can have confidence in the quality and safety of this product.

The size of the words on the web page are too small to read. The picture on the screen cannot be zoomed larger which makes us difficult to read the instructions and Ingredients, etc. The screen shots are the largest size of the words that I could read. It's better to improve for that.
