NOW Foods Magnesium & Calcium 100 Tablets

NOW® Magnesium & Calcium flips the usual formula, using a reverse 2:1 ratio to provide higher levels of magnesium — 800 mg — alongside 400 mg of calcium for people who specifically want magnesium's nerve, muscle and bone-supporting effects to take the lead.* The magnesium is drawn from five forms (including glycinate and taurinate) plus mineral-rich Aquamin® seaweed calcium. Zinc and vitamin D3 are included for their roles in bone metabolism.* It is an ideal pick for those who feel they need more magnesium than a traditional cal-mag provides.*

About the key ingredients

• Magnesium (elemental, from five forms incl. Aquamin®) – 800 mg: A high 800 mg dose from five magnesium forms — oxide, glycinate, taurinate, citrate and seaweed-derived — to support nerve, muscle and bone health and healthy enzyme function.* Learn more about Magnesium from the NIH.
• Calcium (elemental, from Aquamin® seaweed minerals and Citrate) – 400 mg: A supporting dose of calcium, including mineral-rich Aquamin® seaweed calcium, to round out this magnesium-forward bone and nerve formula.* Learn more about Calcium from the NIH.
• Zinc (from L-OptiZinc® Monomethionine) – 15 mg: A highly absorbable form of zinc included for its role in bone metabolism and overall structural health.* Learn more about Zinc from the NIH.
• Vitamin D3 (as Cholecalciferol) – 25 mcg: Supports the absorption of calcium and magnesium and plays a critical role in bone metabolism.* Learn more about Vitamin D 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 reverse-ratio formula is aimed at adults who want magnesium to lead — active people, those under physical stress, and anyone who feels a standard cal-mag doesn't supply enough magnesium for their nerve, muscle and bone needs.* The added zinc and vitamin D3 make it a well-rounded bone-metabolism formula, while the higher magnesium supports relaxed muscles and a calm nervous system.* Certified Kosher and made without gluten, dairy and egg, it suits many dietary preferences.*

Suggested use

Take 3 tablets daily, preferably in divided doses, with food or at bedtime. Store in a cool, dry place after opening.

Frequently asked questions

Why take calcium and magnesium together?
Calcium and magnesium are partner minerals that work together in the body. Both are needed for normal muscle, nerve and blood-vessel function and for building and maintaining a healthy skeleton, and magnesium helps regulate how the body handles calcium.* Supplying them in one formula is a convenient way to support bone and neuromuscular health.*

Why choose the reverse ratio?
Most cal-mag products give you more calcium than magnesium. This one reverses that — 800 mg magnesium to 400 mg calcium — for people who specifically want magnesium's nerve, muscle and bone-supporting effects to predominate, with calcium, zinc and D3 in supporting roles.*

When is the best time to take it?
Many people split the dose and take it with food, and some prefer an evening serving. Taking calcium in divided amounts through the day can support absorption. Follow the serving size on the label or your healthcare provider's guidance, and take it a few hours apart from any medications.

Is this suitable for my diet?
Check the Supplement Facts panel for product-specific certifications — several products in this family are Kosher, Vegan or Non-GMO and are made without gluten, soy, dairy and egg. The exact capsule or coating and any bovine-gelatin content are listed in the Other Ingredients line.

Cautions & interactions

Calcium and magnesium can both reduce the absorption of certain medications — including thyroid medicine, some antibiotics (such as tetracyclines and quinolones), bisphosphonates and iron — so take this product a few hours apart from them and check with your doctor. Very high calcium intake is not appropriate for everyone; talk to your physician before use if you have a history of kidney stones, high blood calcium or kidney disease, and if you take digoxin or thiazide diuretics. Larger magnesium doses may loosen stools. Keep out of reach of children and consult your physician if pregnant, nursing or taking medication.
