NOW Foods Magnesium 500mg 120 Veg Capsules

NOW® Magnesium 500 mg is a high-potency, once-daily capsule that provides 500 mg of elemental magnesium from a thoughtful blend of magnesium oxide, magnesium bisglycinate and magnesium citrate. Magnesium is a required cofactor for an estimated 300 enzymes, driving reactions that include energy production and metabolism, protein and fatty-acid synthesis, and glucose metabolism.* It is also essential for muscle contraction, nerve-impulse transmission and healthy bone mineralization, and it helps regulate the body's calcium balance through its effect on the parathyroid gland.* The bisglycinate portion binds magnesium to the amino acid glycine to help ease intestinal absorption, while oxide and citrate round out the dose, making this a robust choice for people who want a higher amount of magnesium in a single vegetarian capsule.*

About the key ingredients

• Magnesium (elemental, from Magnesium Oxide, Bisglycinate and Citrate) – 500 mg: A potent 500 mg serving from three forms — including gentle, chelated bisglycinate — to deliver a high amount of elemental magnesium for enzyme, nerve and muscle support in one capsule.* Learn more about Magnesium from the NIH.
• Other ingredients: NOW® uses simple, functional excipients — typically a plant-based hypromellose (cellulose) capsule or a light tablet coating plus flow agents such as stearic acid and silicon dioxide — with no unnecessary fillers, artificial colors or preservatives.

Who it's for

This is a straightforward daily magnesium option for adults who want to top up an essential mineral that is easy to fall short on — especially active people, those who sweat a lot, older adults, and anyone whose diet is light on leafy greens, nuts, seeds and whole grains.* It suits people looking to support relaxed muscles, steady energy and a calm, healthy nervous system as part of their everyday routine.* Because NOW® offers magnesium in several forms and strengths, you can match the format to your preference, whether you like capsules, tablets, softgels or a mixable powder.

Suggested use

Take 1 capsule daily. Store in a cool, dry place after opening.

Frequently asked questions

What makes magnesium blend a good choice?
It pairs concentrated magnesium oxide with well-absorbed citrate and gentle, glycine-bound bisglycinate, so you get a high dose that is still comfortable to take.*

What does magnesium actually do in the body?
Magnesium is one of the most widely used minerals in human physiology. It acts as a cofactor for roughly 300 enzymes involved in producing cellular energy, building protein, and metabolizing carbohydrates and fats, and it supports normal muscle, nerve, heart and bone function.* Many modern diets fall short of the recommended intake.

When and how should I take it?
Most people take magnesium daily with food, and some prefer an evening dose as part of a wind-down routine. Follow the serving size on the label or the guidance of your healthcare provider, and if you are new to magnesium, starting with a lower amount lets your digestive system adjust.

Is this product vegetarian and free of common allergens?
NOW® magnesium products are made without wheat, gluten, soy, milk, egg, fish and shellfish ingredients, and most use a plant-based vegetarian capsule or coating. Check the Supplement Facts panel for the exact form and any product-specific certifications such as Kosher, Vegan or Non-GMO.

Cautions & interactions

Magnesium is generally well tolerated, but larger doses can have a natural laxative effect, so it is wise to start low and take it with food. Talk to your doctor before combining magnesium with prescription medicines, because it can reduce the absorption of certain antibiotics (such as tetracyclines and quinolones) and bisphosphonates — separate these by a few hours — and it may add to the effect of some blood-pressure or diuretic medications. If you have reduced kidney function, use magnesium only under medical supervision, since the kidneys clear excess magnesium. Keep out of reach of children and consult your physician if pregnant, nursing or managing a medical condition.
