10. Best tested vitamin C supplement
NOW Buffered C-Complex Powder
Instead of the typical ascorbic acid, this powder features calcium ascorbate, which is a buffered form of vitamin C, meaning it’s less acidic and less likely to cause an upset stomach.
This supplement is also enhanced with naturally vitamin C-rich plant foods, including rose hips and acerola cherry, plus citrus bioflavonoids to boost absorption. Each 1/4 teaspoon contains 500 milligrams of vitamin C.
NOW Foods is known in the supplement industry for its rigorous testing protocols.
