Overview
This capsule pairs chelated magnesium glycinate with vitamin D3, B6 and zinc, marketed by Dr. Berg as a 4-in-1 formula. The brand states it is lab-tested and GMP-certified with no fillers, formulated in the USA, positioning it toward buyers who want reassurance around manufacturing standards alongside the ingredient list.
At 150 capsules per bottle, this is a larger supply than many comparable magnesium glycinate products, which can mean fewer reorders for regular users. It is unflavored, so there is no taste consideration with this capsule format.
Feedback is strong here, with a 4.8 average rating across 4,600 reviews and a reported 20,000 buyers in the past month, making it one of the more actively purchased listings in this range. Since it combines several active ingredients, it is worth talking to a healthcare professional before starting, especially if you already take D3, B6 or zinc separately.
