Can you take calcium and magnesium together?

Short answer: Many supplements combine calcium and magnesium, and taking them together is common. Some people choose to space larger amounts apart because minerals can compete for absorption, but for typical daily amounts taking them at the same meal is usually fine. A pharmacist can tailor this to you.

Together is common, spacing is optional

Plenty of products pack calcium and magnesium into one tablet, which tells you that taking them together is a normal choice. Minerals can compete for absorption when amounts are large, which is why some people separate them.

For everyday amounts, taking both at the same meal keeps your routine simple, and simple routines are the ones people actually keep.

Making minerals part of your day

If you do decide to space them, a reminder for each time makes it effortless. Pillog lets you set separate times, check each off from the notification, and see your month as a card — all on your phone, no account, no ads.

Because ideal amounts and combinations depend on your diet, your doctor or pharmacist is the best guide.
