Analysis

The capsule combines calcium citrate, carbonate, and hydroxide with 3.3 mcg vitamin D3 and 30 mcg vitamin K1. Citrate broadens flexibility, while D3 and K1 add light bone-support cofactors.

Each calcium form is listed at 350 mg even though the serving is one capsule, creating uncertainty about whether those entries are additive or describe a 350 mg blend. Carbonate and hydroxide are less flexible forms and generally fit better with food.

One hundred single-capsule servings provide excellent convenience. Users should confirm the actual elemental calcium amount and view the vitamin D contribution as modest.

Who is it for
  • Adults seeking mixed-form calcium
  • Users who want D3 and K1 included
  • People able to confirm the package calcium total
Best for
  • One-capsule calcium routines
  • Mixed calcium forms
  • Long 100-serving use

Pros

  • Includes calcium citrate
  • Adds vitamin D3 and vitamin K1
  • Requires one capsule
  • Offers 100 servings

Cons

  • True elemental calcium total is unclear
  • Includes carbonate and hydroxide
  • Vitamin D amount is small

Warnings

  • Vitamin K1 can counter warfarin and related vitamin K antagonists; intake should remain consistent under prescriber guidance.
  • Confirm the elemental calcium total because the three 350 mg entries may not be additive.
  • Calcium can reduce absorption of levothyroxine and tetracycline or quinolone antibiotics; separate dosing according to prescriber or pharmacist instructions.

Nutrient quality

87 Highest impact

Calcium citrate improves a blend that also includes carbonate and less-characterized calcium hydroxide. The blend is coherent and sensibly dosed, but form-level calcium disclosure and modest cofactors limit precision.

Ingredient transparency

74 High impact

Totals are shown, but repeated calcium-form amounts make each form’s contribution unclear. No proprietary blend hides the doses, but full directions and inactive ingredients are not supplied.

Customer satisfaction

73 High impact

The supplied average is exceptionally strong, with large response volume. Complaint patterns and purpose-related experiences are not supplied.

Value for money

94 Highest impact

Formula quality appears strong for the asking price. Each serving offers excellent practical value for its useful active dose.

Citrate partly improves a blend that also contains less-preferred carbonate and calcium hydroxide. The 350 mg serving provides a useful moderate amount but may require divided intake for higher needs. No artificial colors, sweeteners, titanium dioxide, or high sugar are disclosed in the supplied data, while the low serving cost provides excellent collection value.

Cal/Mag 500 mg/250 mg

NaturesPlus
<p>Chelated calcium and magnesium provide a focused, balanced mineral formula with strong form quality. Compared with TriCalcium Complex with D & K, its calcium form and supporting nutrients may be a better fit where citrate improves the mixed salt profile, but the calcium split and vitamin K form are not fully clear, while a simple one-serving format and economical cost make it one of the better value profiles in this set.</p>

Magnesium & Calcium

NOW
<p>Well-regarded calcium, magnesium, and zinc forms support a broad mineral profile, although magnesium oxide weakens the blend. Compared with TriCalcium Complex with D & K, its calcium form and supporting nutrients may be a better fit where citrate improves the mixed salt profile, but the calcium split and vitamin K form are not fully clear, while the listed 800 mg magnesium serving is unusually high and may cause diarrhea or abdominal cramping.</p>

Calcium Citrate

Nature's Way
<p>Citrate and malate improve absorption quality within the mixed calcium formula. Compared with TriCalcium Complex with D & K, its calcium form and supporting nutrients may be a better fit where citrate improves the mixed salt profile, but the calcium split and vitamin K form are not fully clear, while active doses are clear, while missing excipient and full use details limit transparency.</p>

600+D3

21st Century
<p>Calcium carbonate and vitamin D3 provide a focused bone-support pairing at exceptionally accessible value. Its lower recurring cost than TriCalcium Complex with D & K makes it a more economical calcium option, while the calcium amount is reasonably sized, though carbonate works best with food and offers less flexibility than citrate. Calcium should be separated from levothyroxine and tetracycline or quinolone antibiotics because it can reduce their absorption.</p>

Calcium Carbonate

NOW
<p>The pure powder supplies a substantial calcium amount with excellent serving value and no unrelated actives. Its lower recurring cost than TriCalcium Complex with D & K makes it a more economical calcium option, while calcium carbonate is less flexible than citrate because food and stomach acid aid absorption.</p>

Calcium 500 mg with Vitamin D3

Nature's Bounty
<p>A practical oyster-derived calcium amount and vitamin D3 provide focused bone support with exceptional affordability. Its lower recurring cost than TriCalcium Complex with D & K makes it a more economical calcium option, while the likely carbonate source is less flexible than citrate, and duplicate vitamin D wording reduces label clarity.</p>
