Analysis

Calcium citrate and magnesium citrate are each supplied at 400 mg, providing a balanced mineral profile in powder form. Both citrate forms are practical choices for absorption and flexible timing.

Vitamin D3 supports calcium use, although five micrograms is a modest amount. The concise formula avoids proprietary blends and lower-quality oxide forms.

Powder allows flexible mixing and may suit people who dislike tablets. Strong value is a clear advantage, while the full magnesium serving may need to be divided for digestive comfort.

Who is it for
  • Adults who prefer powder to pills
  • People seeking equal calcium and magnesium amounts
Best for
  • Balanced bone-mineral support
  • Flexible citrate mineral dosing

Pros

  • Uses calcium and magnesium citrate
  • Includes vitamin D3
  • Strong value and flexible powder format

Cons

  • Vitamin D3 amount is modest
  • Powder requires mixing
  • Equal ratio may not fit every dietary gap

Warnings

  • Four hundred milligrams of magnesium citrate may cause loose stools or cramping
  • Separate calcium from thyroid hormone, bisphosphonates, and some antibiotics
  • People with impaired kidney function should review substantial magnesium use with a clinician

Nutrient quality

95 Highest impact

Calcium and magnesium citrate are practical, reasonably absorbed mineral forms, and cholecalciferol is a useful vitamin D form, and the balanced 400 mg mineral amounts are meaningful, and vitamin D3 adds a useful cofactor. The disclosed amounts show no obvious broad overdosing for typical supplemental use, while calcium, magnesium, and vitamin D form a coherent mineral-support combination.

.

Ingredient transparency

85 Highest impact

The listed active nutrients have specific amounts, and no proprietary blend hides the amount of a listed core mineral. Serving count is supplied, but complete daily-use directions are not provided, while inactive ingredients and excipients are not included in the supplied label details.

.

Customer satisfaction

72 High impact

The supplied average rating is favorable but below the strongest products in this group, and substantial review volume gives the average rating useful credibility. Specific review themes are unavailable, so repeated negatives and real-world fit remain uncertain.

.

Value for money

91 Highest impact

Favorable mineral forms and useful amounts generally justify the product positioning, and the low serving cost provides strong practical value. The listed formula is focused and does not appear padded with low-value active ingredients, while the formula and serving value compare well with similar mineral products.

Calcium and magnesium supply structural minerals, while vitamin D3 supports calcium absorption and magnesium-dependent vitamin D activation. The balanced 400 mg mineral amounts use well-absorbed citrate forms and create a strong bone-focused base.

The vitamin D3 amount is modest, and the formula lacks vitamin K2 or a collagen-related matrix ingredient. Even so, each included pathway receives a clearly disclosed and functionally relevant amount.

Both citrate forms are reasonably absorbed and clearly labeled. Magnesium at 400 mg may loosen stools in sensitive users, especially when taken as a single powder serving.

Magnesium citrate provides substantial support for ATP-dependent metabolism, while balanced calcium and vitamin D3 support neuromuscular function. All forms and amounts are clearly disclosed.

The formula remains a mineral-support product rather than an acute energy aid. Its equal calcium and magnesium amounts are more balanced than calcium-heavy alternatives, though the full magnesium serving may loosen stools.

The 400 mg magnesium citrate amount supports vascular tone, heart rhythm, and normal muscle function. Human cardiovascular benefits are most likely when magnesium intake or status is low rather than as a stand-alone treatment for heart disease.

Calcium and vitamin D3 broadens mineral support but shifts part of the formula toward bone health. Magnesium citrate at this amount may cause loose stools or abdominal discomfort in sensitive users.

A- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyA+ Value

Calcium citrate provides a well-absorbed 400 mg serving that fits the efficient per-dose range. Magnesium citrate and vitamin D3 complement the calcium, while no unwanted additives are shown in the supplied facts. The powder also offers strong cost efficiency for a citrate-based formula.
