Product analysis

50 out of 100

Chewable Tablets Bone Restore Chocolate Flavored can help fill calcium and magnesium gaps relevant to normal bone maintenance. Magnesium oxide is a less favorable source for absorption.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality31

Calcium combines carbonate and citrate in unknown proportions, while magnesium uses less favorable oxide. The horsetail source also does not establish the particular silicon preparation behind the more specific findings.

Ingredient Transparency69

The ingredient amounts and most sources are stated. Some forms and the calcium-source proportions are missing, limiting a full comparison.

Value For Money39

Calcium has a moderate value comparison and silicon a reasonable one. Magnesium and boron are relatively costly, while several other contributions remain uncertain.

Customer Satisfaction69

Customer ratings are positive, but the number of entries is small. The limited pool leaves the picture of satisfaction less settled.

Product Focus57

The clearest purpose is mineral support for normal bones when dietary intake is low. Numerous secondary uses do not establish added joint, hair or cardiovascular benefits beyond their nutritional roles.

Magnesium · 300 mgCalcium · 700 mgVitamin D · 25 mcgManganese · 1 mgBoron · 3 mgZinc · 2 mg

Calcium supplies bone mineral, vitamin D supports calcium absorption, and magnesium contributes to normal bone metabolism when intake is low. Together they address mineral supply and its regulation, without establishing fracture prevention. The 700 mg calcium serving can fill a meaningful intake gap, though total daily needs include food and absorption is more efficient at smaller amounts. Horsetail-derived silicon does not establish equivalence to the choline-stabilized orthosilicic acid used in the exploratory bone study.

How this product is rated for Bone Health

Ingredient fit76

Calcium, vitamin D and magnesium provide the clearest nutritional fit; silicon's preparation limits its interpretation.

Calcium provides a substantial contribution toward bone-mineral needs when dietary intake falls short. Magnesium adds nutritional availability related to energy and mineral metabolism, while vitamin D also helps fill a nutrient gap. Their amounts do not establish extra benefit in adequately nourished adults, and the supplied evidence does not establish a special combination effect.

Zinc supports normal testosterone production when low zinc intake or deficiency is corrected; extra zinc has not shown a testosterone benefit when intake is adequate. Magnesium has limited hormone findings from a small study involving exercise, which do not establish a routine testosterone increase. Vitamin D findings are mixed and any benefit may depend on initial deficiency. Boron has inconsistent, short-term hormone findings.

How this product is rated for Testosterone Support

Ingredient fit61

The main relevant ingredients are Zinc, Vitamin D, Magnesium. Their amounts and the broader formula determine how closely the product matches this goal.
Goal fit
The formula centers more closely on zinc and vitamin d and magnesium, though its hormone benefits remain conditional.
