More in Antioxidant

Other ingredients in the Antioxidant category.

Alpha-Lipoic Acid (ALA)

Universal antioxidant working in both water and fat. Regenerates other antioxidants and supports blood sugar metabolism.

Astaxanthin

Astaxanthin is a carotenoid with potent antioxidant and anti-inflammatory properties, naturally present in krill and microalgae. It crosses the blood–brain barrier and may support eye, skin, and cellular health.

Broccoli

Broccoli powder is a whole-food derived ingredient rich in sulforaphane, glucosinolates, and polyphenols that support antioxidant and detoxification pathways. Evidence supports potential benefits for cellular health and inflammatory response, though most human research uses fresh broccoli or concentrated extracts rather than powder forms.

C60 (Carbon 60 Fullerene)

Spherical carbon molecule with potent antioxidant properties in olive oil. Controversial with limited human data despite promising rodent longevity studies.

CoQ10 (Ubiquinone/Ubiquinol)

Ubiquinol is the reduced, active form of CoQ10 that plays a critical role in cellular energy production via the mitochondrial electron transport chain and serves as a lipid-soluble antioxidant. It is more bioavailable than standard ubiquinone (oxidized CoQ10), particularly in aging populations.

Ergothioneine

Longevity amino acid with unique cellular uptake via dedicated transporter. Potent antioxidant concentrated in mitochondria, potential longevity compound.
