Taking Calcium with Multivitamin: Is it SAFE or Not?

Short Answer: It is generally safe to take calcium and multivitamin together or one after another.

Calcium and multivitamin both are healthy supplements.

Calcium contains calcium carbonate or calcium citrate, which are essential for bone health and muscle function.

Multivitamin has various vitamins and minerals, such as vitamin A, B, C, D, E, K, iron, zinc, magnesium, etc., which are important for overall health and immunity.

According to Ayurveda, calcium and multivitamin should not be taken together or one after another, as they may interfere with each other’s absorption and cause imbalance in the body.

Ayurveda believes that calcium is a cold substance and multivitamin is a hot substance, and they should be taken separately with a gap of at least two hours.

Ayurveda also suggests that calcium and multivitamin should be taken with natural sources of these nutrients, such as amla, moringa, sesame seeds, and milk.

But according to science, calcium and multivitamin can be taken together or one after another, as long as the total daily dose of each supplement does not exceed the recommended upper limit.

Science says that calcium and multivitamin do not have any significant adverse effects on each other’s absorption or metabolism.

However, some studies suggest that taking high doses of both supplements may increase the risk of hypercalcemia (too much calcium in the blood), which can cause kidney stones or heart problems.

As a nutritionist, my advice is to try first.

If after taking calcium and multivitamin together or one after another can cause side effects, such as nausea, vomiting, constipation, diarrhea, headache, or irregular heartbeat, then stop combining them. And if you can tolerate them, then continue.

However, you should be mindful of the quality and quantity of calcium and multivitamin you consume.

Because too much or too little of either supplement can have negative consequences on your health.

Whether you take them together or not, you should always choose high-quality supplements that are tested for purity and potency.

Because some supplements may contain contaminants or additives that can harm your health.

You should also consult your doctor before taking any supplements, especially if you have any medical conditions or are taking any medications.

You can store calcium and multivitamin in a cool, dry place away from sunlight and heat. Do not store them in a bathroom or near a window.

Keep them in their original containers with tight lids. Do not use them after their expiration date.

Finally, remember, calcium and multivitamin are supplements that can help you meet your daily nutritional needs.

But they are not substitutes for a balanced diet that includes a variety of foods rich in these nutrients. You should also exercise regularly and drink plenty of water to maintain your health.
