The finest antidote to free radical harm is antioxidants, that are electron donors. Antioxidants can break the free radical chain response by sacrificing their very own electrons to feed free radicals with out turning into free radicals themselves. As lengthy as you may have sufficient antioxidants in your physique, it is possible for you to to higher resist untimely getting older and ailments brought on by your on a regular basis publicity to toxins and pollution.

Both are required by the physique to guard your cells because the inside of your cells and the fluid between them are composed of water, whereas the cell membranes are principally product of fats.
- Lipid-soluble antioxidants – examples embrace nutritional vitamins A and E, carotenoids, and alpha lipoid acid.
- Water-soluble antioxidants – examples embrace vitamin C, plant polyphenols, and glutathione (GSH).
2. Enzymatic and non-enzymatic antioxidants
- Enzymatic antioxidants break down and take away free radicals by changing them into hydrogen peroxide, then into water. Enzymatic antioxidants can’t be present in dietary supplements, they’re solely produced by the physique. Examples embrace superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSHpx), and glutathione reductase.
- Non-enzymatic antioxidants interrupt free radical chain reactions by doing a “first sweep” to disarm the free radicals. This helps stop your enzymatic antioxidants from being depleted. Most antioxidants present in meals and dietary supplements are of this sort. Examples embrace carotenoids, nutritional vitamins C and E, plant polyphenols, and glutathione (GSH).
3. Small-molecule and large-protein antioxidants
- Small-molecule antioxidants work by mopping up the free radicals and carrying them away by chemical neutralization. Examples are nutritional vitamins C and E, glutathione (GSH), alpha lipoid acid, carotenoids, and CoQ10.
- Large-protein antioxidants act like “sacrificial proteins”. They “take the bullet” for essential enzymes and DNA by absorbing free radicals and stopping them from attacking your important proteins. instance is albumin, present in blood plasma.
Best Antioxidant-Rich Foods
First, as talked about earlier, you shouldn’t give attention to only one or two antioxidants. It is crucial that you simply absorb all kinds of antioxidants as all of them serve completely different functions.

Whey protein supplies all the important thing amino acids for making glutathione within the physique. Buy solely natural whey from grass-fed cows to keep away from the poisonous chemical substances utilized in manufacturing unit farming. Choose cold-processed since warmth destroys whey’s fragile molecular construction. Only use whey protein focus, not protein isolate because the latter isn’t an entire meals. Other meals that enhance glutathione manufacturing embrace uncooked dairy (not pasteurized dairy), eggs, and grass-fed meats.
Last however not least, train additionally boosts your glutathione ranges. So incorporate some types of bodily exercise on a regular basis.
