Magnesium Glycinate 100mg
NOW Foods offers the best balance of quality and affordability for those on a budget. Unlike many budget brands, NOW performs extensive in-house testing and is UL-certified for manufacturing quality.
Ingredients & Purity
100mg elemental magnesium per tablet. Uses a highly absorbable glycinate form, though the tablets are relatively large and may be difficult for some to swallow.
Scientific Evidence
NOW is one of the few brands with an in-house lab capable of testing for heavy metals and microbial contaminants on every batch.
Brand Transparency
Publicly available info on their testing protocols and GMP certifications. They are a family-owned company with a long history of compliance.
Value Assessment
Exceptional value. Often available for under $20 for a 180-count bottle, making it the most cost-effective way to get high-quality chelated magnesium.
Why Not Alternatives?
It beats drugstore brands like Nature Made by using a superior glycinate form rather than oxide. However, it loses to Thorne/Pure due to the use of more excipients (stearic acid, silica) and larger tablet size.
