Overview
Nutricost's Magnesium+ combines magnesium oxide and magnesium glycinate into a single 420 mg extra-strength serving, blending a common high-dose form with a form often chosen for better tolerability.
The 240-capsule bottle is sized for 120 servings at two capsules each, roughly a four month supply at one serving a day. Blending oxide with glycinate is a middle-ground approach, since oxide delivers more elemental magnesium by weight while glycinate is generally gentler on the stomach.
- 420 mg magnesium per serving from oxide and glycinate
- 240 capsules, 120 servings, about a four month supply
- Non-GMO and gluten free
- Vegan-friendly formulation
Who it's for
People wanting a higher 420 mg magnesium dose who are comfortable with a two-capsule serving and a blended oxide-glycinate formula. Less suited to someone who wants a single, purely glycinate-only or citrate-only magnesium product.
Pros and cons
- 420 mg extra-strength dose per two-capsule serving
- Blends magnesium oxide with glycinate for a tolerability balance
- 120 servings, roughly a four month supply
- Non-GMO, gluten free, vegan-friendly
- Two-capsule serving means more pills per dose than a single-capsule product
- Blended formula means buyers cannot isolate one magnesium form alone
Performance notes
Magnesium oxide provides a higher percentage of elemental magnesium per milligram but can be harder on the digestive system, while magnesium glycinate is typically better tolerated. Combining the two in one capsule balances dose strength against tolerability rather than choosing one extreme.
