Overview
NOW Solutions Magnesium Flakes are a 100% pure magnesium product sourced from an ancient seabed, sold in a concentrated 54-ounce package. The listing markets it toward skin health rather than as a swallowed capsule supplement.
Despite one data field labeling the form as capsule, the product name and packaging describe flakes, which is how NOW sells this line: dissolved in bath water rather than taken orally like a typical pill. Buyers looking for an oral magnesium capsule should double check the listing, since this appears to be the topical, bath-soak version of NOW's magnesium range. The 54-ounce size points to a bulk, multi-use bath product rather than a single-serving tablet.
- 54-ounce bag of magnesium flakes
- Sourced from an ancient seabed
- Positioned for skin health, used as a soak
- Vegan and vegetarian
Who it's for
Fits anyone looking for a topical magnesium soak for skin, rather than an oral magnesium capsule or tablet for daily supplementation. It is the wrong pick for someone who specifically needs an ingestible magnesium product, since flakes are meant to dissolve in bath water.
Strengths and trade-offs
Drawn from this product's published specifications.
- Large 54-ounce size for repeated use

- Marketed for skin health
- Vegan and vegetarian

Performance notes
As flakes, this product dissolves into water rather than being swallowed, a different use case from magnesium capsules or tablets aimed at digestion and absorption through the gut. The 54-ounce size supports repeated bath use over time rather than a single course of servings.
