Description
Natural Factors’ timed-release vitamin C is a long-running staple in Canadian health stores. This 210-tablet value size suits people who already take one a day and want fewer reorders.
What the label says
- Timed release over an 8-hour period, according to the brand.
- Supports immune system function.
- Collagen formation for wound repair, gums, bones and teeth.
- Citrus bioflavonoids are added for extra antioxidant protection.
- ISURA verified clean; vegan, non-GMO, gluten free, formulated and packaged in B.C.
- NPN 00469459.
Who it may suit
Long-term daily users and couples sharing a bottle get the most out of the value size. The slow release is a plus for those who find quick-dissolving forms harsh. Vegans will also note the vegan claim on the label.
How it compares
Dose matches the Webber Naturals and Jamieson timed-release options at 1,000 mg, with the advantage of added bioflavonoids and a stated 8-hour window. At 210 tablets it lasts seven months on one a day, which generally lowers the cost per tablet. The NPN is listed, which confirms Health Canada authorization.
Timed-release products are sometimes larger than ordinary tablets because of the extra matrix material. Taking them with a full glass of water and a meal tends to make swallowing easier, and it also helps with any mild stomach sensitivity.
Tips for taking vitamin C
A few practical points: food in the stomach usually makes vitamin C gentler, and two smaller servings tend to sit better than one big one. The general ceiling is 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; above that, digestive upset becomes more likely. Anyone prone to kidney stones, or on regular medication, should check with a pharmacist before starting.
