Choosing the Right Magnesium Supplement
Magnesium Forms and Absorption
Not all magnesium is created equal. The Nutricost Magnesium Complex combines three distinct forms: magnesium oxide, magnesium citrate, and magnesium glycinate. Each has its own absorption profile and benefits. Oxide offers a high elemental magnesium content, citrate is known for its digestive tolerance and bioavailability, and glycinate is often favored for calming effects. This triple blend aims to cover multiple needs in one pill.
If you prefer a single-form, highly absorbable magnesium, our sports research magnesium L threonate review discusses a form that crosses the blood-brain barrier, which may support cognitive health.
Dosage and Potency
Each serving delivers 500mg of magnesium from the three sources. That’s a substantial dose, especially for those with higher needs or active lifestyles. The 240 capsules provide 240 servings, meaning you can take one capsule per day or split the dose as directed. For a standard 8-month supply, it offers consistent convenience.
When considering magnesium for sleep, you might also explore how it pairs with other herbs. Our article on ashwagandha and magnesium for sleep explains synergistic combinations.

Frequently Asked Questions
How does Nutricost Magnesium Complex differ from magnesium citrate alone?
This product includes magnesium citrate along with oxide and glycinate. While citrate is highly bioavailable, the addition of glycinate may promote calming effects and oxide provides a higher elemental dose. The blend aims to cover more ground than a single form.
Is it safe to take Nutricost Magnesium Complex every day?
For most adults, a daily 500mg magnesium dose is within recommended limits, but it’s wise to consult your healthcare provider, especially if you have kidney issues or are on medication. The supplement is designed for daily use and offers a long supply.
Can this supplement help with sleep? In 2026, magnesium glycinate is often linked to better sleep quality due to its calming properties. The glycinate component in this blend may support relaxation, though individual results vary. If sleep is your primary goal, compare it with our sports research magnesium glycinate review for a dedicated glycinate option.
What is the serving size and capsule count?
The recommended serving is one capsule, providing 500mg of magnesium. With 240 capsules per bottle, you get a 240-serving supply, which can last up to eight months if taken once daily.
