Analysis

This supplement provides a robust 1300mg of calcium sourced from eggshells. It includes Vitamin D3 and a small amount of Vitamin K2 (MK-7) to help direct the calcium into your bones rather than your arteries.

The eggshell calcium is a natural source of calcium carbonate that many find easy to digest. While it is more expensive than basic salts, the inclusion of signaling vitamins makes it a more comprehensive choice for skeletal health.

Pros

  • Uses natural eggshell calcium
  • Includes Vitamin K2 as MK-7
  • High 1300mg dose of calcium
  • Provides 20mcg of Vitamin D

Cons

  • Very high price per serving
  • Vitamin K2 dose is quite low
  • Tablets are large

Warnings

  • Check for egg allergies
  • Drink plenty of water when taking high-dose calcium

Nutrient quality

90 Highest impact

Using natural eggshell calcium and Vitamin K2 (MK-7) is a significant quality driver for skeletal health. Potent dosages for all active ingredients support multiple functional pathways.

Ingredient transparency

98 Highest impact

Labeling clearly specifies the weights and chemical forms for every active ingredient. This comprehensive disclosure provides consumers with clear information regarding the supplement's composition.

Customer satisfaction

84 Highest impact

High ratings indicate that users are satisfied with this comprehensive bone health formula. A smaller review volume still provides evidence of consistent quality and performance.

Value for money

64 Moderate impact

The cost per serving is higher than average, reflecting the use of premium ingredients and cofactors. It represents a fair value for individuals seeking comprehensive skeletal support.

A- Goal FitB Strength of SupportC+ CoverageA Formula Quality

Eggshell calcium provides a high-density structural source of calcium carbonate for bone mineral density. Cholecalciferol and menaquinone-7 offer essential signaling for directing those minerals into the skeletal matrix.

The 1,300mg calcium dose is robust but may exceed the optimal single-dose absorption efficiency for many users. While provide signaling cofactors, the MK-7 dose is relatively low compared to therapeutic benchmarks for bone health.

B+ Goal FitD+ Strength of SupportD- CoverageC+ Formula Quality

This formula includes calcium, Vitamin D3, and Vitamin K2 (as MK-7) to support mineral metabolism and structural health. Vitamin K2 appears well aligned with the goal of managing calcium distribution and protecting the arteries from calcification.

While MK-7 is the correct form for arterial support, the 20 mcg dose is very low and considered sub-therapeutic for clinical heart benefits. The primary focus is on skeletal health, which may not translate into significant cardiovascular protection at these levels.

C+ Goal FitF Strength of SupportF CoverageC- Formula Quality

This formula primarily targets bone health through high-dose Calcium and Vitamin D3, but also includes a minimal 20 mcg dose of Vitamin K2 (MK-7). While K2 is relevant for vascular health, this dose is far below the levels used in clinical cardiovascular research.

The inclusion of Calcium in such high amounts (1300 mg) could potentially be a concern for vascular health if not properly balanced by higher doses of Vitamin K2. This product is not well aligned as a primary cardiovascular support tool.

Report overview
C+ Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyF Value
This bone support formula includes Vitamin K2 as MK-7, but at a very low dose that acts only as maintenance. The tablet format is also not optimized for the absorption of these fat-soluble nutrients.
C+ Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value
This bone support supplement utilizes eggshell calcium along with vitamins D3 and K2. While the ingredient quality is good, the extremely high dose and price per serving make it a less efficient choice.
