Product analysis
Silica Complex combines minerals involved in normal bone processes at a low serving cost, but undisclosed horsetail and bentonite forms make quality comparisons harder.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality39
The manganese form is a positive quality feature, while the boron form offers a less clear advantage. Missing horsetail and bentonite form details limit comparison of the full combination.
Ingredient Transparency88
Amounts and most forms are declared, which helps comparison. Horsetail and bentonite form details are missing, and the usable individual horsetail amount remains unclear.
Value For Money54
The serving cost is very favorable when considered for manganese, and boron offers fair value. Value for the other ingredients remains uncertain.
Customer Satisfaction73
Customer feedback is very positive. The moderate review base provides some perspective on satisfaction without showing bone benefits.
Product Focus44
Boron and manganese take part in normal bone processes, but extra intake does not establish added bone benefits. Calcium and zinc amounts are small, and the horsetail details do not establish a comparable silicon preparation.

Boron and manganese participate in mineral metabolism and bone-matrix processes, but those roles do not establish routine bone benefits from extra supplementation. Calcium and zinc are present at small amounts that are not counted in the saved findings. Horsetail has no resolved individual amount, and its botanical identity does not establish the elemental silicon preparation used in bone studies.
How this product is rated for Bone Health
Ingredient fit68
Boron, manganese and horsetail are counted in the saved findings, though horsetail has no usable amount contribution.
Goal fit
The counted ingredients relate to bone, with a modest reduction in focus from another active and other goal links.
Dose adequacy
Boron and manganese contribute at partial relative amounts; horsetail's unresolved amount adds nothing.
Pathways19
Calcium regulation and matrix formation receive partial contributions.
Depth
Calcium regulation is the strongest route, but remains below the coverage threshold.
Breadth
No route reaches the coverage threshold.
Evidence88
Boron leads the saved evidence finding, although its routine independent skeletal benefit remains unestablished.
Evidence strength
Boron leads the saved evidence category.
Studied preparation
The two contributors with recognized amounts were accepted as studied.
Formulation logic92
Partner requirements are met, but horsetail does not meet the amount threshold; no configured conflict was found.
Partner coverage
All counted contributors can stand alone or have their required partner.
Conflicts
No configured ingredient conflict was found.
Effective doses
Boron and manganese meet the saved amount threshold; horsetail does not.
Horsetail Not classified
No linked studies yet.

Manganese (Manganese Amino Acid Chelate) · 2 mg OverallScore82
Each serving provides 2 mg of manganese as an amino acid chelate. The specific amino acid is not identified in the saved information, limiting comparisons by form.
How this ingredient is rated
Active Ingredient Quality & Bioavailability70
The manganese source is described as an amino acid chelate, but the specific amino acid is not identified in the saved information.
Manganese Chemical Form
The source is an amino acid chelate; the specific chelating amino acid is not established in the saved information.
Dose, Safety & Label Transparency86
The manganese amount is individually listed at 2 mg per serving.
Manganese Dosage Efficacy & Safety
Each serving lists 2 mg of manganese; the evaluation considers the amount per serving.
Elemental Weight Disclosure
