NIH DSLD label 293714. The hero ingredient (apoaequorin) has no credible independent evidence of benefit at any dose.

This grade is a ceiling: it assumes the label is accurate. Laboratory testing can only lower it.

Supplement formulas change. This verdict reflects the label data on file as of its source date. Always confirm against the physical label before you buy. Unsold grades formulas, not brands - and we're not doctors. This is information, not medical advice; check with a qualified healthcare professional before changing what you take.

Documented quality-control evidence found in public sources — manufacturer claims, facility audits, or independent certification. It does not mean Unsold tested this product, verified its purity, or confirmed what is in the tub in your hand, and it never changes the Formula Grade above.
