Sports Research is better known for omega-3s and collagen, but its high-potency vitamin C follows the same approach: third-party certifications on the front of the bottle and a large count.

Who it may suit

Shoppers who look for third-party seals such as Non-GMO Project and vegan certification will like this one. It also suits gym-goers already using the brand’s other products.

What the label says

Claims from the brand’s listing:

High-potency vitamin C at 1,000 mg, in veggie capsules.
Vitamin C is described as an antioxidant that helps healthy cells.
Non-GMO Project Verified and Vegan Certified.
Made in cGMP-compliant facilities in the United States.

How it compares

The listing states 1,000 mg but does not say how many capsules make one serving, so check the supplement facts panel in the Amazon.ca images. Compared with the CanPrev 240-capsule bottle, it is American-made rather than Canadian, so look for an NPN on the Canadian label before buying. Large counts usually give a good value per serving.

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.

Tips for taking vitamin C

If plain vitamin C upsets your stomach, take it with a meal. Splitting a larger amount into a morning and an evening dose is a common way to make it easier to tolerate. Keep your total from all sources 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. People with a history of kidney stones should be cautious with high-dose vitamin C, and a pharmacist can check it against any medication you take.
