Decision summary

CONSIDERAVERAGE

A middling option. It may be usable, but weaker ingredient form quality makes better alternatives worth comparing.

Best for

Buyers comparing price and availability and okay with a middle-of-the-pack option.

Consider another option if

You care a lot about label clarity and want fewer unknowns.

Score breakdown

Tap a module to see what it measures. A 0 can reflect missing disclosure, not just a negative result.

Dosage quality

6.2/10

Acceptable dosing, but not standout

Checks whether labeled ingredient amounts fall within clinically studied ranges (not just regulatory minimums). Low/0 can reflect under-dosing or missing amounts (e.g., proprietary blends).

Score summary

The supporting evidence profile is relatively strong. The main limitation is that proprietary blend prevents independent dose verification.

Strengths

The supporting evidence profile is relatively strong
The formula stays relatively clean on excipients
The safety profile looks solid

Weaknesses

Proprietary blend prevents independent dose verification
Calcium: below clinically studied range
Calcium: chemical form not specified on label

Final verdict

A middling option. It may be usable, but weaker ingredient form quality makes better alternatives worth comparing.

Clinical dosing guidance

Based on established dosing ranges used in clinical practice.

⚠ Strong evidence exists, but dose is below effective threshold

A clear drag on the formula: Dose is likely below clinically useful levels. The label does not specify the form, so absorption quality cannot be verified.
