Antioxidants are compounds that help protect your cells against the oxidative damage caused by free radicals — the everyday wear that comes with normal metabolism. Providing a source of antioxidants for the maintenance of good health is exactly what most products on this shelf are labelled to do. Some, like vitamin C and vitamin E, are familiar nutrients; others, like CoQ10, NAC and superoxide dismutase, are more specialized ingredients that shoppers often arrive here looking for by name.
Form matters more here than in many aisles. Fat-soluble antioxidants like CoQ10 and vitamin E typically come as softgels and absorb best taken with a meal that contains some fat. You'll also see CoQ10 in two versions — conventional ubiquinone and the "active" ubiquinol form — along with formulas that add black-pepper extract (BioPerine) to support absorption. Water-friendly options include NAC tablets, veggie capsules and even organic acerola juice, a naturally vitamin C-rich cherry pressed into a liquid you measure by the capful.
When choosing, start with the ingredient you came for, then compare the amount per serving, the form and the capsule type — many options here are vegetarian. If you're weighing a straightforward single ingredient against a combination formula, the label's medicinal-ingredients panel tells the real story. And as with any supplement, check with your health-care practitioner before adding something new, especially if you take medications — the Greenbrook team is happy to help you read a label side by side.
