Formula guide

Two magnesium forms in one formula

The product combines oxide and citrate. The complete Supplement Facts panel remains the right place to confirm serving size and elemental-magnesium quantity.

01

Magnesium oxide

One of the two magnesium compounds named on the current product label.

02

Magnesium citrate

The second named magnesium compound; this makes the product different from a single-form oxide formula.

03

500 mg statement

The front label states 500 mg per serving. Confirm what that amount represents on the current Supplement Facts panel.

Suggested use

One capsule, one to two times daily

The current label says: “1 capsule taken 1 to 2 times daily preferably with meals or as directed by a healthcare professional.”

Supplemental magnesium can interact with some medicines. People with kidney disease or other medical conditions should ask a healthcare professional before use.

Questions & answers

What shoppers ask before buying

Direct answers based on the current label and official Centurion Health product page.

What is Number One Nutrition Magnesium Complex?

It is a dietary supplement that combines magnesium oxide and magnesium citrate in vegetable capsules. The current front label states 500 mg per serving, and the bottle contains 120 capsules.

Which forms of magnesium are included?

The formula includes magnesium oxide and magnesium citrate. It is a two-form magnesium product and does not list magnesium glycinate on the current official product page or front label.

Does each capsule contain 500 mg of elemental magnesium?

Do not infer that from the front label alone. It states 500 mg per serving, while magnesium compounds and elemental magnesium are not the same measurement. Check the current Supplement Facts panel for serving size and the amount listed specifically as magnesium.

Is Magnesium Complex the same as magnesium citrate?

No. Magnesium Complex contains both magnesium citrate and magnesium oxide. A single-form magnesium citrate product contains citrate without the added oxide form.

Does Magnesium Complex contain magnesium glycinate?

No magnesium glycinate is identified on the current official product page or front label. Shoppers specifically seeking glycinate should compare the complete Supplement Facts panel before purchasing.

How many capsules are in the bottle?

The current bottle contains 120 vegetable capsules. The label's suggested use says: “1 capsule taken 1 to 2 times daily preferably with meals or as directed by a healthcare professional.” That provides a 60- to 120-day supply, depending on use.

Is it non-GMO?

The current front label identifies the product as non-GMO. Review the complete current package if a dietary restriction or allergen concern is essential to you.

Can magnesium supplements interact with medication?

Yes, supplemental magnesium can interact with certain medicines, including some antibiotics and osteoporosis medicines. Ask a healthcare professional or pharmacist about timing and suitability if you use medication.

Who should ask a healthcare professional before using it?

People with kidney disease, a medical condition, pregnancy or nursing status, or regular medication use should ask a qualified healthcare professional before taking a magnesium supplement.

Where can I buy the authentic product?

Use the official Centurion Health product page to verify the current package, availability, price, and purchasing options. Centurion Health advises shoppers to avoid unauthorized marketplace resellers.
