Analysis

The orange-flavored tablets provide 1,000 mg of calcium as citrate, a form that does not depend heavily on stomach acid. Calcium directly supports bone mineral intake, but the full amount is too large for efficient absorption in one sitting.

The serving also contributes 7 g of carbohydrate and 30 calories, a meaningful trade-off for a calcium product. No vitamin D or vitamin K is included to support absorption or calcium handling.

Only 15 servings are supplied, making continued use less economical than many capsule or liquid alternatives. The flavored format may improve acceptability, but users should be prepared to divide the serving and account for its carbohydrate load.

Who is it for
  • Adults who strongly prefer flavored calcium tablets
  • People who tolerate citrate better than carbonate
  • Users able to divide the serving across the day
Best for
  • Pill-averse users who want a flavored format
  • Citrate-based calcium supplementation
  • Divided high-dose calcium use

Pros

  • Uses calcium citrate
  • Provides a substantial calcium amount
  • Flavored format may be easier for some users

Cons

  • Contains 7 g of carbohydrate per serving
  • Only 15 servings are supplied
  • Lacks vitamin D and vitamin K

Warnings

  • The 1,000 mg calcium serving is best divided when directions allow; taking it at once may reduce absorption and increase stomach discomfort.

Nutrient quality

74 High impact

Calcium citrate provides favorable form quality and a meaningful mineral amount. The oversized serving and carbohydrate-heavy format weaken balance and purity.

Ingredient transparency

83 Highest impact

Calcium and macronutrient amounts are clearly stated without a hidden blend. Timing guidance and the complete flavored-tablet ingredient list are missing.

Customer satisfaction

65 High impact

The aggregate rating is acceptable and supported by a large evidence base. No specific experience details are supplied to explain weaker sentiment or purpose fit.

Value for money

43 Lower impact

The citrate form provides genuine quality. High recurring cost and a carbohydrate-heavy serving make category value weak.

Calcium · 1000 mg

Calcium citrate supplies the main structural mineral in bone in a form with good absorption potential. The product is directly relevant to filling a calcium gap but does not address mineral placement or the protein matrix.

The full serving is larger than the amount usually absorbed most efficiently at one time, so divided use may improve uptake. The chewable format also contributes a notable carbohydrate load without adding vitamin D or vitamin K.

Report overview
A- Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

Calcium citrate offers good absorption potential. The 1000 mg serving is larger than the amount usually absorbed most efficiently at once, and the chewable format carries a high sugar load. The high cost further limits its practical appeal.
