leaderboard Score 42.0
An extremely cheap high-dose magnesium oxide, but ineffective for systemic magnesium needs.
Quantity: 500
Swanson Magnesium 200 mg (effectively 400mg per serving based on quantity/servings and ingredient list) utilizes magnesium oxide. This form is known for its poor systemic bioavailability, meaning very little of the magnesium is absorbed into the body for general health purposes, with its main action being a laxative effect. Its incredibly low price point makes it one of the most cost-effective options per milligram of elemental magnesium, though its actual physiological benefit for deficiency is limited.
- Exceptional affordability per serving.
- Delivers a high elemental dose of magnesium.
- Composed of magnesium oxide, which has very low bioavailability for systemic use.
- Primarily useful for its laxative properties rather than correcting magnesium deficiency.
- Potential for laxative effects, especially with regular use.

Categories
Magnesium 42.0
As a magnesium supplement, its primary drawback is the use of magnesium oxide, which limits its systemic benefits, placing it lower in the category despite its very low cost.
Goals
General Health 42.0
Its contribution to general health is significantly hampered by the magnesium oxide's poor systemic absorption, making it less effective for overall wellness compared to other forms.
Energy 37.0
For magnesium to impact energy production, it must be absorbed systemically, which is not efficiently achieved by the magnesium oxide form.
Heart Health 37.0
Supporting heart health requires bioavailable magnesium, which is poorly provided by the magnesium oxide in this supplement.
