WHY IS THIS IMPORTANT?

Reduced Ca2+ATPase levels contribute to many diseases including cardiovascular disease, high blood pressure, cancer, obesity, diabetes, and brain dysfunction.

Many toxins such as pesticides, mercury, lead, fluoride, fire retardants, bisphenol, food additives, food dyes and dietary states such as hyperglycemia reduce Ca2+ATPase.

Most importantly, you can help to maintain healthy Ca2+ATPase levels by reducing your exposure to many of the toxins that reduce Ca2+ATPase. In addition to avoiding toxins, controlling your blood sugar, exercising and choosing specific supplements such as green tea, ginger, and vitamin E can support Ca2+ATPase levels.

LEARN ABOUT Ca²⁺ATPase

WHAT IS CA²⁺ATPASE?

Ca2+ATPase is an enzyme found in every cell in the body whose job it is to regulate intracellular calcium. Intracellular calcium is simply the level of calcium within the cells.

What is intracellular calcium?

The body contains approximately 2.2 pounds of calcium in total. 99.5 % of this resides in bones, tissues and teeth (which is likely the calcium you are most familiar with.) The remaining 0.5% of calcium circulates within the blood stream available for use by the cells. This calcium is used by the cells to trigger actions. A rise in intracellular calcium triggers an event to happen.

For example:
1. In muscle cells, a rise in intracellular calcium triggers muscle contraction.
2. In cardiac cells a rise in intracellular calcium triggers the heart to beat.
3. In brain cells, a rise in intracellular calcium triggers neurotransmitter release.

Once the event has occurred, Ca2+ATPase helps return intracellular calcium levels back to resting levels. It does this by pumping excess calcium into storage compartments within the cells. The storage compartment is called the sarcoplasmic or endoplasmic reticulum depending on what type of cell it is.

Why are intracellular calcium levels important?

If you continue the metaphor used in the video below of intracellular calcium serving as a traffic light, imagine if the traffic signals in a city were not working properly. You can imagine the potential problems that this could cause. Then imagine the millions of processes controlled by intracellular calcium in your body every second, every minute, of every day. When calcium levels go awry, we become significantly more susceptible to disease.

Obesity

  • Ca²⁺ATPase is responsible for approximately 40% of calories burned by your muscles and approximately 12-15% of total calories burned.

Blood Clots

  • Blood clots typically occur when you have a cut, the clumping of the blood helps to reduce blood loss. This is called platelet aggregation. However, excessive sustained platelet aggregation can significantly increase your risk of heart attack and stroke. Ca²⁺ATPase, through its stimulation by nitric oxide — a substance the body releases in response to platelet aggregation — is the primary mechanism through which platelet aggregation is reduced and the likelihood of blood clots goes down.

Inflammation

  • When Ca²⁺ATPase is reduced, mast cells release inflammatory substances. The substances released by mast cells are associated with numerous inflammatory conditions, including irritable bowel, arthritis, and other chronic conditions, including diabetes and cardiovascular disease.
