Scoring criteria

Quantity
75 / 100
The evaluated 300 mg daily butyric-acid dose is a moderate supplemental amount, but adequacy for the stated colon-support role remains somewhat uncertain.
Form
65 / 100
The label names butyric acid but does not clearly identify whether it is supplied as a specific calcium or magnesium butyrate form, leaving relevant form properties unresolved.
Convenience
63 / 100
The smallest labelled routine is one capsule three times daily, providing 300 mg butyric acid, 270 mg calcium, and 255 mg magnesium daily.
Label accuracy
100 / 100
The quantified serving amounts and directions are internally consistent without an established dose contradiction.
Purity
75 / 100
The label lists conventional capsule excipients and provides no product-specific contaminant or manufacturing-control evidence.
Cofactors
0 / 100
Calcium and magnesium are quantified but no established complementary benefit beyond possible salt-counterion or incidental roles is demonstrated for this purpose.
