NOW Foods Magnesium & Potassium Aspartate 120 Veg Capsules

NOW® Magnesium & Potassium Aspartate with Taurine brings together two of the body's most important electrolyte minerals — 250 mg of magnesium and 99 mg of potassium, both in the well-absorbed aspartate form — plus 100 mg of free-form taurine. Magnesium and potassium are found throughout the body and are especially critical for healthy heart and vascular function, proper nerve-impulse transmission and muscle contraction.* Taurine further supports neuromuscular and cardiovascular health through its role in regulating normal electrolyte and neurotransmitter balance.* Together they make a targeted formula for people focused on heart and muscle wellness.*

About the key ingredients

• Magnesium (elemental, from Magnesium Aspartate) – 250 mg: A well-absorbed aspartate form of magnesium that supports healthy heart, muscle and nerve function and helps maintain normal electrolyte balance.* Learn more about Magnesium from the NIH.
• Potassium (elemental, from Potassium Aspartate) – 99 mg: An essential electrolyte mineral that works with magnesium to support healthy fluid balance, nerve signaling and normal heart and muscle function.*
• Taurine (Free-Form) – 100 mg: A conditionally essential amino acid that helps regulate normal electrolyte and neurotransmitter balance, supporting neuromuscular and cardiovascular health.*
• 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

Frequently asked questions

What makes magnesium aspartate a good choice?
Both minerals are provided as aspartates — bound to aspartic acid — a form chosen to support absorption, and paired here with taurine for heart and muscle support.*

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

Because this product contains potassium, talk to your doctor before using it if you take blood-pressure medications, potassium-sparing diuretics, ACE inhibitors or other drugs that affect potassium levels, or if you have kidney concerns — excess potassium must be avoided in these situations. Magnesium can also affect the absorption of some antibiotics and bisphosphonates, so separate dosing by a few hours, and larger doses may loosen stools. Keep out of reach of children and consult your physician if pregnant, nursing or managing a medical condition.
