Good to know
- Tums Regular Strength is 500 mg and Tums Ultra Strength is 1000 mg — compare by milligrams, not by tablet count.
- Each Tums Extra Strength 750 tablet provides about 300 mg of elemental calcium, per its label.
- Kirkland Signature's antacid is a 1000 mg (ultra strength) tablet, so it is not listed in this group.
