The absolute cheapest magnesium product, but entirely composed of poorly absorbed magnesium oxide, making it primarily a laxative and ineffective for systemic benefits.
Quantity: 100
This Nature's Bounty Magnesium 500 mg product is identical in formulation to ID 159715, containing only Magnesium Oxide. It distinguishes itself by offering an even larger quantity at an incredibly low price per serving, making it the cheapest option. However, its effectiveness for systemic absorption remains critically low (around 4%), rendering it largely useless for addressing magnesium deficiencies or supporting core health goals like energy, stress, or bone health. Its primary and almost sole utility is as an osmotic laxative. The exceptionally high review count reflects its widespread availability and affordability, not its systemic efficacy.
- Unbeatable low price per serving, making it extremely budget-friendly.
- Highly accessible and widely available from a major retail brand.
- Effective as a laxative.
- Solely contains magnesium oxide, which has extremely poor bioavailability for systemic absorption.
- Provides minimal actual magnesium for the body's metabolic or physiological needs.
- Ineffective for addressing true magnesium deficiencies or providing broad health support.
- Primarily functions as a laxative; likely to cause loose stools or digestive discomfort if taken for systemic effects.
