This site's headline reads: a few drops a day for steadier blood sugar. Worth reading closely, word by word.
"Steadier" is a comparative word, not an absolute one. The site pairs it with its own framing that GlucoPril supports blood sugar levels already within a normal range, so the headline is about steadiness, not about correcting a problem.
The headline does not mention amounts, and this site states elsewhere that individual milligram amounts are not disclosed. Read the headline as positioning, and check the detail on your own bottle.
