Analysis

Nature's Bounty Magnesium 500 mg exclusively contains Magnesium Oxide. As extensively discussed, this form has very poor absorption rates (around 4%), meaning that a minimal amount of the stated 500mg elemental magnesium will actually be absorbed and utilized by the body for systemic benefits such as nerve function, energy production, or bone health. Its primary utility is as an osmotic laxative. While the product is exceptionally inexpensive and widely available from a popular brand, it is a poor choice for individuals seeking to effectively increase their systemic magnesium levels or address a deficiency for broader health support.

Pros
  • Extremely low price per serving, making it very budget-friendly.
  • Widely available and accessible from a major retail brand.
Cons
  • Composed entirely of magnesium oxide, which is poorly absorbed for systemic benefits.
  • Primarily functions as a laxative rather than an effective magnesium supplement for health goals.
  • Provides minimal actual magnesium for the body's metabolic or physiological needs.
Warnings
  • Primarily functions as a laxative; frequent or high doses may cause digestive discomfort, cramping, or loose stools.
