Increase antioxidant capacity

What this outcome means

Antioxidant capacity is your body's measured ability to neutralize reactive molecules and keep oxidative stress in check. On DoseRank it maps to a defined health outcome built from human studies on total antioxidant capacity assays, oxidative stress markers, and lipid peroxidation levels – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

High oxidative loadHeavy training, pollution, or smoking that raises oxidative stress.

Metabolically stressedConditions where reactive molecules outpace the body's defenses.

Prevention-mindedPeople tracking oxidative markers as part of long-term health.

Stack buildersAlready taking supplements such as Ascorbic Acid or Selenomethionine and want the dose right.

Evidence level

85Strong

Selenomethionine – has strong public evidence, and Ascorbic Acid adds supporting evidence. DoseRank looks at both evidence quality and formula fit. A DoseFit Score of 67 means this product's ingredient forms and doses are close to what was used in the studies behind this ranking - DoseRank weights each product ingredient.

Best ingredients

Antioxidants & Bioactive Compounds

4.2k products

Molecules that neutralize free radicals and tune cell signaling. Helpful in balance; mega-doses can blunt the body's own adaptive defenses.

Typical: , , , ...

Vitamins

5.1k products

Essential micronutrients the body can't make in sufficient amounts. Fat-soluble ones (A, D, E, K) store up; water-soluble ones need regular topping-up.

Typical: , , , ...

Amino Acids & Derivatives

1.2k products

The building blocks of protein, taken singly for targeted effects – leucine for muscle, theanine for calm. Free-form versions absorb fast on an empty stomach.

Typical: , ,

Minerals & Trace Elements

2.5k products

Inorganic nutrients from calcium to zinc. The chemical form drives absorption – chelates and citrates usually beat cheap oxides.

Typical: , , , ...

Botanicals/Herbal Extracts

5.4k products

Concentrated plant and herbal extracts standardized to actives. Potency depends on the extract ratio and marker content, not raw weight.

Typical: , , , ...

Enzymes

41 products

Proteins that speed specific reactions, from digesting food to thinning fibrin. Taken with meals for digestion or away from food for systemic effects.

Typical:

Hormones & Hormone-like Compounds

618 products

Compounds that signal like the body's own hormones — melatonin, DHEA, pregnenolone. Powerful at tiny doses and easy to overdo; timing matters more than potency.

Typical:

Glandulars & Animal-Derived Extracts

124 products

Animal gland and organ-tissue extracts used traditionally for targeted organ support. Purity and grass-fed sourcing are the key quality markers.
