Foods and supplements claimed to help antioxidant defence and ageing
65 of them, ranked by strength of evidence. None reach grade A or B.
At a glance
65 foods and supplements marketed for antioxidant defence and ageing, each graded one by one against clinical trial evidence. Grade spread: C 26 · D 10 · F 1. None reach grade A or B.
The grade measures how strong the evidence is, not how good something is for you. Grade A means independent research groups replicated a reduction in real clinical events in humans; grade F means well-designed trials established there is no effect. See Methodology.

What does have evidence for antioxidant defence and ageing
Not foods or supplements: drugs and procedures graded A or B. Chamgap recommends nothing. It only shows where the evidence is strong. Any treatment decision belongs with your doctor.
| B | 74 | Topical tretinoin (prescription all-trans retinoid cream) | Improved fine wrinkles, mottled pigmentation, and rough texture of facial photoaging |
| B | 72 | Walking about 7,000 to 10,000 or more steps per day | Lower all-cause mortality through a special 10,000-step threshold |

How to read this list
A grade of C or D does not mean "do not take it." It means the evidence is not yet strong enough to promise the effect. Equally, A or B does not mean it works for everyone.
