Description
The 1,000 mg on the front of this bottle refers to calcium ascorbate, not pure vitamin C. That buffered, non-acidic form is the whole point: Webber Naturals made it for people who get heartburn or cramps from ascorbic acid.
How it compares
Per capsule you get 820 mg of actual vitamin C, a little less than a 1,000 mg ascorbic acid capsule. That is a fair trade for gentleness, and it compares with the buffered Sisu Ester-C at 600 mg. Webber Naturals is Canadian and its NPN is on the bottle.
Large bottles look like the best deal, but vitamin C slowly loses potency once a bottle is opened, especially in humid bathrooms. Store it in a cool, dry cupboard with the lid tightly closed, and check the expiry date printed on the label when the package arrives.
What the label says
Details from the brand:
- Each capsule provides 820 mg of vitamin C and 94 mg of calcium from calcium ascorbate.
- The calcium buffers the vitamin C to help prevent stomach irritation.
- Intended for people who usually have digestive symptoms with vitamin C, or who want a higher dose.
- Vitamin C is water-soluble and needed daily.
- Free of artificial colours, preservatives, sweeteners, dairy, gluten, soy, corn and GMOs.
Who it may suit
Anyone who has given up on vitamin C because of stomach discomfort is the obvious audience. Count the calcium if you also take a calcium supplement.
Tips for taking vitamin C
- Take it with food if you have a sensitive stomach.
- Split doses through the day rather than taking everything at once.
- Stay under 2,000 mg a day for adults, the tolerable upper intake level set out by Health Canada and the U.S. National Institutes of Health, counting fortified foods and other supplements.
- Talk to a doctor first if you have had kidney stones.
- Ask a pharmacist about interactions with your prescriptions.
