Analysis

Providing 2000mg of total calcium per serving, this powder uses a blend of carbonate and citrate forms. It includes a small amount of Vitamin D3 to assist with the absorption of these minerals.

This is a very high dose, far exceeding the 500-600mg that the body can typically process at once. It is a clean formula but lacks the balance of magnesium and Vitamin K2 for optimal bone health.

Pros

  • No artificial flavors or fillers
  • Mixes easily into various liquids
  • Includes a maintenance dose of D3
  • Provides both citrate and carbonate

Cons

  • Extremely high dose limits absorption efficiency
  • No magnesium included
  • Lacks Vitamin K2

Warnings

  • Measure carefully as the dose is very concentrated

Nutrient quality

73 High impact

Selection of a citrate and carbonate blend provides a decent variety of mineral sources. However, the total dose of 2000mg per serving is excessively aggressive and likely to result in wasted nutrients.

Ingredient transparency

97 Highest impact

Labeling clearly identifies the multiple mineral forms and total elemental yields for accurate intake tracking. Usage instructions for the powder format are straightforward and appropriate.

Customer satisfaction

82 Highest impact

Ratings reflect high satisfaction with the purity and high-dose potential of the unflavored powder. Review volume is relatively modest, but indicates consistent approval from the current consumer base.

Value for money

87 Highest impact

Price per serving is moderate considering the massive amount of elemental calcium provided. However, the inefficiently high dose per serving reduces the overall practical value of each purchase.

A Goal FitB+ Strength of SupportC CoverageA- Formula Quality

Calcium Carbonate and Citrate provide foundational support for bone mineral density. A maintenance amount of Vitamin D3 is included to assist with structural mineral transport.

Delivering 1000 mg of calcium in a single serving exceeds the physiological absorption ceiling. This unflavored powder is a clean option for mineral support but lacks additional cofactors like Vitamin K2.
