Overview

['NOW Foods markets this as a highly absorbable magnesium glycinate tablet, dosed at 100 mg per serving and packaged in a 180 count bottle. Magnesium glycinate is generally chosen by shoppers who want a gentler form of magnesium compared to oxide based tablets, and the 180 count size gives a longer runway before a repurchase is needed.', 'At just under 20 dollars, the price sits in the mid range for glycinate formulas, and the brand has a long track record in the supplement space. The listing itself does not detail flavor, diet certifications or specific stated benefits beyond the glycinate form and absorption claim, so shoppers wanting those details may want to check current packaging.', 'Buyer response is strong, with a 4.7 rating from 8,000 reviews and a reported 10,000 units bought in the past month, suggesting reliable repeat demand. As always, it is worth discussing any new supplement with a healthcare professional before starting it.']
