GNC Super Magnesium is a 300 mg magnesium supplement formulated with three highly absorbable forms to support healthy body function.
Magnesium is an essential part of the product’s stated support for healthy function. GNC Super Magnesium brings that support together in capsule form, making it an option for shoppers looking for a magnesium supplement with a defined strength, a combination of forms, and a stated supply duration. Its listed benefits include both body-function support and support for healthy bones and teeth.
GNC Super Magnesium is formulated to support healthy heart, nerve, muscle, and bone function. These are the specific areas named for its magnesium support, alongside the stated support for healthy bones and teeth. This makes the product relevant to shoppers seeking a supplement with several clearly identified areas of intended support rather than a single-function formula.
GNC Super Magnesium combines three highly absorbable forms of magnesium in one formula. The product is supplied as capsules, with 300 mg of magnesium identified in its name. The combination of forms is the formula’s defining feature, while the capsule format provides a compact way to take the supplement.
Each supply contains 90 capsules and is identified as a 30-day supply. This gives shoppers a clear quantity and duration when choosing a magnesium supplement. The listed supply duration is useful for understanding the product’s intended supply size; no capsule-per-day direction is inferred here.
