Balanced Milk Mineral Complex for Bone Support

TruCal® Provides Bones with Much More than Just Calcium.

Calcium in the form of calcium carbonate leads in the type of calcium that appears in most nutritional supplements. However, it and other forms of calcium are limited and do not fully provide the body with what bones need for proper support. Consumers are generally aware that calcium sourced from milk is good for the body but it also contributes a host of other beneficial minerals that provide balanced mineral support for bone health. TruCal is a balanced milk mineral complex delivering 6 minerals (Calcium, Phosphorus, Magnesium, Potassium, Zinc, and Copper) all at similar levels to the normal mineral composition of bone.

TruCal® Provides Minerals at the Right Balance

Bones need a mineral balance, not just calcium. 

MineralRole in Supporting Bone Health
  • 99% stored in bones/teeth to provide structure and strength.
  • The majority of Phosphorus is present in bone and teeth (85%), with the remainder distributed between other tissues (14%) and extracellular fluid (1%). 
  • Phosphorus is crucial for bone growth and mineralization. 
  • Supports bone building but improper balance of phosphorus may block the generation of new bone and may increase risk of osteoporosis.
  • The majority of total Magnesium is stored in the bone (60%) and is responsible for supporting bone strength and growth.
  • Critical to activating enzyme systems
  • Magnesium is necessary for the proper utilization of vitamin D and calcium, contributes to energy production and helps regulate calcium levels.
  • Helps to maintain bone density.
  • Potassium may alter bone metabolism by promoting calcium retention at the kidney.
  • Zinc takes part in the growth and maintenance of healthy bones.
  • In bone metabolism, zinc is needed to produce the matrix of collagen protein threads upon which the bone-forming calcium – phosphorus compound is deposited.
  • Copper is an essential trace mineral that has only recently been found to play an important role in bone health maintenance.
  • Copper helps inhibit bone resorption through a copper- and zinc-containing antioxidant called superoxide dismutase. This antioxidant neutralizes superoxide radicals produced by the bone-breakdown cells called osteoclasts during bone resorption.


TruCal® provides a balanced milk mineral complex for optimal bone health.

  • Scientifically shown to help improve bone density and strength8
  • Contains minerals sourced directly from cow’s milk, delivering them in ratios similar to the composition of bone.
  • This natural balance supports the growth and maintenance of the bone structure8.


Mineral Bone Content TruCal Milk Minerals
Calcium 25% 24%
Phosphorus 12% 12.5%
Magnesium 0.37% 1.5%
Potassium 0.7% 0.8%
Zinc 0.009% 0.008%
Copper 0.0005% 0.0004%

Other common forms of calcium lack the additional essential minerals necessary to support bone health.

  • Calcium Carbonate
  • Tricalcium Phosphate 
  • Calcium Phosphates
  • Calcium Lactate
  • Calcium Citrates
  • Calcium Gluconate
  • Calcium Lactate Gluconate

See why TruCal® is such an integral source of calcium and minerals for your supplement and food products. 

Studies Show Superior Results Compared to Calcium Carbonate

TruCal® Showed Superior Results to Calcium Carbonate for Bone Breakdown8

  • TruCal significantly lowered Urine Helical Peptide (UHP), which indicates a reduction in the level of bone breakdown and resorption.
  • Calcium carbonate induced no change. 

TruCal® Showed Superior Results to Calcium Carbonate for Bone Turnover8

  • TruCal significantly lowered Bone Alkaline Phosphatase (BAP), which indicates a reduction in the level of bone turnover. 
  • Calcium carbonate induced no change. 

Ideal for a Wide Range of Applications

Frequently Asked Questions

Bones need a balance of minerals to support growth and the maintenance of bone structure, density and strength. Fortification with only calcium cannot provide the full support needed. 

TruCal contains 25% calcium, 12% phosphorus, 0.37% magnesium, 0.7% potassium, .009% zinc and .0005% copper. 

In a clinical study, TruCal was shown to significantly lower the markers of bone resorption and turnover when compared to calcium carbonate.8

TruCal is a versatile ingredient that can be included in powder drink mixes, ready-to-drink beverages, tablets, capsules, snacks, bars, cheeses and yogurts.
