Every day your cells produce a kind of internal rust. It is a normal byproduct of turning food and oxygen into energy -- but left unchecked, it damages cell membranes and DNA. Antioxidants are the shield that keeps that rust in balance. This is the deficiency-and-toxicity axis in its clearest form: a normal amount of oxidation is just metabolism running; too much of it, unmatched by enough antioxidant defense, is where the trouble starts.
What free radicals actually are
A free radical is an unstable molecule missing a piece, so it grabs a piece from whatever is nearby -- a membrane, a protein, your DNA. That grabbing is oxidation, the same process that rusts metal and browns a cut apple. A little is normal. A lot, sustained, is what we call oxidative stress -- too much of a normal signal, not a foreign toxin, which is exactly why the fix is building up the shield rather than eliminating oxidation itself.
Where antioxidants come in
Antioxidants neutralize free radicals by safely giving up a piece without becoming damaging themselves. Your body makes some (like glutathione) and gets others from food (like vitamin C, vitamin E, and CoQ10).
The shield is a team, not a single player
This is the part worth slowing down on. Antioxidants are not independent bodyguards each covering their own patch -- research describes them working as a network that regenerates itself. When vitamin E neutralizes a free radical inside a fatty membrane, it becomes spent, and vitamin C appears able to donate back what was lost and regenerate it.[1] Glutathione, the body's own major internal antioxidant, appears to help regenerate vitamin C in turn, and that recycling of glutathione depends on selenium as a cofactor.[3] The colorful plant pigments below, anthocyanins among them, work alongside this same relay rather than apart from it. The practical point: a shield built from one isolated nutrient at a high dose is a weaker shield than a varied one, because the network's whole advantage is members covering and recharging each other.
The colorful plant pigments, in plain terms
A specific family of antioxidant micronutrients, obtained primarily from fruits and vegetables, is what makes carrots orange, tomatoes red, and greens deep green. Those pigments build up in your skin over weeks to months, which is what makes them measurable -- PRYSM iO reads that antioxidant status in about 15 seconds with no blood draw, as a window into your fruit-and-vegetable nutrient status.[4] Take a reading, follow the nutrition plan built from it, and read it again: your score goes up, measurably, or your money back.
How to build your shield
Eat the rainbow, every day. Different colors carry different antioxidants, and they work as a team.
- Reds and oranges -- the antioxidant pigments in tomatoes, carrots, peppers.
- Deep greens -- lutein and folate from leafy vegetables.
- Blues and purples -- anthocyanins from berries.
- Support players -- CoQ10, alpha lipoic acid, and adequate selenium for glutathione.[2]
Key Takeaways
- Oxidation is internal rust -- normal in small amounts, damaging when chronic; the axis is too little shield, not too much oxidation.
- Antioxidants neutralize it; some you make, some you eat.
- Antioxidants work as a regenerating network -- vitamin C helps recycle vitamin E, glutathione helps recycle vitamin C, and selenium keeps that recycling running -- not as isolated soloists.
- The colorful plant pigments are what PRYSM iO reads as an antioxidant status score, with a guarantee the score goes up, measurably, or your money back.
- Eating a full spectrum of colors builds a broader shield than any single supplement.
