Qunol Magnesium 420mg, Extra Strength, High Absorption, Vegetarian, 180ct Review
Qunol Magnesium Extra Strength 420 mg is a once-daily dietary supplement expertly formulated to support nerve, bone, muscle, and heart health. Nearly half of Americans (48%, according to an analysis of NHANES 2013-2016 data) do not ingest enough magnesium from food and beverages alone to meet their nutritional needs. To help bridge this nutritional gap, each two-capsule serving of Qunol Magnesium Extra Strength delivers 420 mg of magnesium, providing 100% of the recommended Daily Value in two convenient capsules. The formula is specifically focused on superior absorption, utilizing buffered chelated magnesium glycinate, which offers high absorption compared to regular magnesium composed of 100% magnesium oxide, and provides extra strength potency compared to Qunol Magnesium 200 mg Gummies. As an essential mineral backed by the trusted medical science of Qunol, this high-absorption supplement promotes healthy nerve, bone, and muscle function, while also helping to support muscle relaxation and a healthy response to occasional stress. For daily use, adults are instructed to take two capsules daily, or as recommended by a healthcare professional. The displayed 120-count bottle (with a 180-count option also listed on the page) contains 60 servings per container. In addition to its active ingredient of 420 mg buffered chelated magnesium glycinate, the product is made with a vegetarian hydroxypropyl methylcellulose capsule, silicon dioxide, and magnesium stearate. It is thoughtfully crafted to accommodate dietary restrictions and preferences: the formula is completely gluten-free, vegetarian, made without animal-derived ingredients, and formulated without synthetic dyes. Furthermore, it is free of major food allergens, including milk, egg, fish, shellfish, wheat, peanuts, and their by-products.
