Cal-Ma Plus® supports endocrine, cellular, and metabolic functions.*

  • Encourages healthy blood calcium levels
  • Contains key ingredients from Calcium Lactate along with bovine parathyroid to support healthy parathyroid function, which is required for the proper regulation of calcium metabolism*
How does this product help support cellular function?

Calcium and magnesium play important roles at the cellular level; for example, both calcium and magnesium serve as a second messenger in many cell-signaling pathways.1,2 Adequate calcium consumption appears to be important in maintaining healthy blood pressure.3 Calcium and magnesium work in tandem to promote normal nerve function.4*

How does the calcium in this product support health?

Calcium and magnesium are of critical importance to human health, especially bone health.5,6 Bones and teeth contain 99 percent of the calcium found in the human body, while bones alone contain 50-60 percent of the magnesium present in the body.7 Both calcium and magnesium are essential in the maintenance of bone structure and body function.8,9,10 Cal-Ma Plus provides 15 percent of the recommended daily value for calcium in each three-tablet dose.*

How does Cal-Ma Plus support endocrine function?

The endocrine system’s parathyroid gland produces parathyroid hormone to regulate calcium levels in the body. When serum calcium levels are too low, the parathyroid gland releases more parathyroid hormone, causing bone resorption (breakdown) to re-allocate calcium from bones to the blood.11 Parathyroid hormone also increases the formation of active vitamin D to increase the absorption of calcium.12 Magnesium can also exert similar effects on pararathyroid hormone.13 Additionally, the level of cellular calcium affects the release of insulin from insulin-producing cells in the pancreas.14,15*

Whole Food Nutrient Solutions

Since 1929, Standard Process has been the visionary leader in whole food nutrient solutions. We apply systems thinking to holistic nutrition that empowers practitioners to transform lives. Dedicated to the whole food philosophy of our founder, Dr. Royal Lee, our goal is to carry on his mission to provide nutrients for the body that are as close as possible to how they are found in nature.

Our products include foods that are prepared in a way that safeguards their nutritional value. The majority of these ingredients are grown locally on our certified organic farm and may require chopping, dicing, juicing, and/or drying for use in our products. The resulting whole food ingredients are then added to a formula that may include whole food extracts, animal tissue extracts and concentrates, botanicals, whole food isolates, and synthetic ingredients. These highly complex combinations contain a variety of elements designed to trigger trophic effects that support the body’s healthy balance and wellness.*
