## Introduction

**Antioxidants** neutralize free radicals—unstable molecules that damage cells and accelerate aging. Your body produces some antioxidants, but diet is essential for staying in balance. Vitamins C and E, plus minerals like selenium and zinc, are especially important for skin, immune function, and long-term disease prevention.

At **Three Rivers Concierge Medicine in St. Louis**, our concierge doctors use dietary assessments, counseling, and targeted supplementation to help patients build resilient antioxidant defenses.

## 1) What Antioxidants Do—and Why They Matter

Free radical overload (from pollution, UV, smoking, stress, and ultra-processed foods) causes oxidative stress, which contributes to heart disease, cancer, and cognitive decline. Antioxidants donate electrons to stabilize free radicals, protecting cells and slowing damage.

## 2) Key Antioxidant Vitamins & Minerals

- **Vitamin C:** Immune support, collagen synthesis, wound healing; citrus, berries, peppers, leafy greens.
- **Vitamin E:** Protects cell membranes; nuts, seeds, spinach, sunflower oil.
- **Beta-carotene/Vitamin A:** Vision, skin, immune support; carrots, sweet potatoes, mangoes.
- **Selenium:** Enables glutathione peroxidase; thyroid and immune support; Brazil nuts, seafood, whole grains.
- **Zinc:** Immune and tissue repair with antioxidant properties; oysters, beef, pumpkin seeds, chickpeas.

Balance matters—over-supplementing can backfire. We help you find the sweet spot.

## 3) Health Benefits You Can Feel

- **Immune strength:** Antioxidants protect immune cells and can shorten illness duration.
- **Skin vitality:** Vitamin C and carotenoids support collagen and defend against UV-induced damage.
- **Heart protection:** Reduced LDL oxidation lowers atherosclerosis risk; selenium and Vitamin E support vascular health.
- **Brain support:** Vitamin E and polyphenols protect neurons and are associated with healthier cognitive aging.
- **Lower inflammation:** Fewer oxidative triggers can reduce chronic inflammatory load.

## 4) How to Eat More Antioxidants

- **Eat the rainbow:** Mix berries, greens, tomatoes, crucifers, and orange vegetables.
- **Nuts & seeds daily:** Almonds, walnuts, sunflower and pumpkin seeds.
- **Choose whole grains:** Oats, quinoa, brown rice, barley.
- **Use teas & spices:** Green tea, turmeric, cinnamon, cocoa.

We’ll build a plan that fits your routine—grab-and-go, family-style, or restaurant-friendly.

## 5) When Supplements Make Sense

Diet first. But supplements can help when intake or absorption is limited. Examples: Vitamin C during high stress, selenium if intake is low, or zinc for wound healing. Caution: very high beta-carotene is not advised for smokers.

## 6) Long-Term Upside

- **Longevity:** Healthier skin and tissues; slower cellular aging.
- **Lower chronic disease risk:** Better heart, metabolic, and brain outcomes.
- **Faster recovery:** Less oxidative burden after illness or surgery.

## Conclusion

Antioxidants are your body’s everyday defense team. With a colorful diet and strategic supplementation, you can support immunity, heart and brain health, and skin vitality.

Our **concierge doctor** team in St. Louis and Creve Coeur can personalize an antioxidant plan that fits your life.
