Thorne Iron Bisglycinate 25mg vs Doctor's Best High Absorption Magnesium 100mg

Thorne Iron Bisglycinate 25mg: Thorne Iron Bisglycinate is the gold standard for gentle iron supplementation. The bisglycinate chelate causes dramatically fewer GI side effects than ferrous sulfate — the form most commonly prescribed by GPs. NSF Certified for Sport ensures purity, and Thorne's pharmaceutical-grade excipients (leucine instead of magnesium stearate) reflect their premium positioning. The main drawback is price.

Doctor's Best High Absorption Magnesium 100mg: Doctor's Best High Absorption Magnesium uses the patented Albion TRAACS chelate, which is considered the gold standard in mineral chelation technology. Bioavailability is excellent and the bisglycinate form is gentle on digestion. The 240-tablet bottle offers good long-term value, though the serving size of 2 tablets for 100mg elemental is less convenient than some competitors.
