Nature Made Magnesium Oxide 400mg vs BetterYou Magnesium Body Spray

Nature Made Magnesium Oxide 400mg: Nature Made Magnesium Oxide is the budget option — cheap, high-dose on paper, but with the worst bioavailability of any magnesium form at roughly 4-5% absorption. The ingredient list includes titanium dioxide (banned in EU food since 2022), soy, and gelatin. It works as a laxative but is a poor choice for addressing magnesium deficiency or improving sleep, muscle function, or stress.

Scores: effectiveness: 4/10, ingredient_quality: 4/10, value_for_money: 5/10, side_effects: 4/10, certifications: 6/10, overall: 4/10

BetterYou Magnesium Body Spray: BetterYou Magnesium Body Spray offers a unique transdermal delivery method, bypassing the digestive system. Sourced from the Zechstein seabed — the purest natural magnesium source — the formula is exceptionally clean with just two ingredients. While transdermal absorption science remains debated, many users swear by it for muscle relaxation and restless legs.
