How much elemental calcium is in Tums?

2 min read

Tums products contain calcium carbonate, a compound that is approximately 40% elemental calcium by weight. This means that the amount of actual, usable calcium your body receives from a Tums tablet depends on its specific strength.

Quick Summary

Different strengths of Tums contain varying amounts of elemental calcium, with Regular Strength having 200 mg, Extra Strength containing 300 mg, and Ultra Strength providing 400 mg per tablet. Elemental calcium is the actual amount absorbed by the body. This guide details the specific elemental calcium content across the product line.

Key Points

  • Elemental vs. Carbonate: The active ingredient in Tums is calcium carbonate, which is only about 40% elemental (usable) calcium by weight.

  • Dose Varies by Strength: Elemental calcium content differs per tablet, with Regular Strength containing 200 mg, Extra Strength 300 mg, and Ultra Strength 400 mg.

  • Take with Food for Absorption: For optimal calcium absorption, Tums (calcium carbonate) should be taken with meals.

  • Limit Dose Size: To maximize the amount of calcium absorbed, do not take more than 500-600 mg of elemental calcium at a time.

  • Check for Vitamin D: Look for products that include Vitamin D, as it helps with calcium absorption.

  • Citrate vs. Carbonate: Calcium citrate is another common supplement type that is better absorbed on an empty stomach and is less likely to cause constipation than calcium carbonate.

Understanding Calcium Carbonate in Tums

Calcium carbonate, the active ingredient in Tums, is a compound where only a portion is elemental calcium, the form your body can absorb. Roughly 40% of calcium carbonate by weight is elemental calcium. This is why a tablet containing 1000 mg of calcium carbonate doesn't provide 1000 mg of usable calcium.

Tums serves a dual purpose: neutralizing stomach acid for heartburn relief and acting as a calcium supplement. For calcium absorption, it's best taken with food, as stomach acid aids the process.

Elemental Calcium in Different Tums Products

The amount of elemental calcium varies by Tums product strength. The Supplement Facts label will show the precise amount. Common strengths include:

  • Tums Regular Strength (500 mg Calcium Carbonate): Contains 200 mg of elemental calcium per tablet.
  • Tums Extra Strength (750 mg Calcium Carbonate): Provides 300 mg of elemental calcium per tablet.
  • Tums Ultra Strength (1000 mg Calcium Carbonate): Delivers 400 mg of elemental calcium per tablet.
  • Tums Chewy Bites (750 mg Calcium Carbonate): Also offer 300 mg of elemental calcium per chew.
  • Tums Chewy Delights (1177 mg Calcium Carbonate): Provide 470 mg of elemental calcium per chew.

Knowing the elemental calcium content is key, especially if using Tums for daily supplementation.

Comparison of Tums and Other Calcium Supplements

When considering calcium supplements, comparing calcium carbonate (Tums) to calcium citrate is helpful. Factors like cost, absorption needs, and side effects play a role in the choice.

Feature Calcium Carbonate (Tums) Calcium Citrate
Elemental Calcium Content Higher (approx. 40%) Lower (approx. 21%)
Absorption Requires stomach acid; best absorbed with food. Can be taken with or without food; good for those with low stomach acid.
Pill Burden Often requires fewer tablets for an equivalent dose of elemental calcium. More tablets may be needed to achieve the same elemental calcium dose.
Cost Typically less expensive. Generally more expensive.
Common Side Effects More likely to cause constipation, gas, and bloating. Less likely to cause digestive side effects.

Tips for Maximizing Calcium Absorption from Tums

To improve calcium absorption from Tums:

  • Take with food: Calcium carbonate absorbs best with meals because stomach acid aids dissolution.
  • Limit your dose: Absorb no more than 500-600 mg of elemental calcium at once. Split larger daily doses.
  • Avoid certain inhibitors: Limit caffeine, high-salt foods, and alcohol when taking supplements as they can hinder absorption.
  • Check for Vitamin D: Vitamin D is vital for calcium absorption. Some Tums include it; otherwise, ensure adequate intake from other sources.

Conclusion

The elemental calcium content in Tums depends on the product strength, ranging from 200 mg in Regular Strength to 400 mg in Ultra Strength. Since calcium carbonate is only about 40% elemental calcium by weight, always check the label for the precise elemental amount. Tums is a cost-effective calcium source, but calcium citrate might be better absorbed by those with low stomach acid. For optimal absorption from Tums, take with food and divide doses if needed. Consult a healthcare provider for personalized advice on calcium intake.

Frequently Asked Questions

Calcium carbonate is the compound listed as the active ingredient in Tums, while elemental calcium is the actual, usable calcium that your body absorbs. Calcium carbonate is roughly 40% elemental calcium by weight.

Each tablet of Tums Extra Strength contains 750 mg of calcium carbonate, which is equivalent to 300 mg of elemental calcium.

Each tablet of Tums Ultra Strength contains 1000 mg of calcium carbonate, providing 400 mg of elemental calcium.

Tums Regular Strength tablets contain 500 mg of calcium carbonate, which supplies 200 mg of elemental calcium per tablet.

To maximize absorption, you should take Tums with food. The calcium carbonate requires stomach acid for proper absorption, and eating a meal stimulates acid production.

Tums can be a good and affordable source of calcium, especially for individuals who need an antacid as well. However, because absorption is tied to stomach acid, other forms like calcium citrate might be better for those with low stomach acid.

To calculate the elemental calcium from a product containing calcium carbonate, multiply the total milligrams of calcium carbonate by 0.40. For example, a 1250 mg tablet provides 500 mg of elemental calcium (1250 x 0.40 = 500).
