67 out of 100

Iron-Free Multminerals Plus Boron supplies minerals that support bone nutrition and normal nutrient functions when intake falls short. The calcium and magnesium mixtures have undisclosed proportions, making their absorption harder to judge.

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

Nutrient Quality79

Several trace minerals have clearly identified forms, while the calcium and magnesium mixtures are harder to compare. Their undisclosed proportions prevent a confident judgment about the combined forms.

Ingredient Transparency80

The mineral amounts and forms are disclosed throughout the formula. The proportions within several mineral mixtures remain unclear.

Value For Money42

Value varies across minerals, with potassium comparing favorably and boron, zinc and magnesium less economically. Each comparison uses the whole formula’s cost rather than a separate price for each mineral.

Customer Satisfaction79

Customer feedback is favorable across hundreds of reviews. The review volume provides a reasonably broad view of satisfaction.

Product Focus50

The broad mineral formula is most relevant to nutritional gaps, including those affecting bones and normal immune function. Higher amounts do not establish extra energy, stress relief or other benefits when needs are already met.
