Did you know nearly 7% of Americans are unknowingly deficient in vitamin C, compromising their immune health, skin health, and overall well-being? Vitamin C isn't just a humble nutrient you find in oranges; it's a critical antioxidant your body depends on, but can't produce by itself.
With modern diets often falling short on fresh produce (and up to 60% of vitamin C vanishing during cooking), it's clear we've got a nutritional blind spot ripe for addressing.
To bridge this gap, supplementation can be a smart strategy. If you've ever considered supplementing, our complete guide on Vitamin C supplementation explains exactly why this nutrient deserves your full attention and how improving your intake can positively affect your health span.
Key takeaways
- Vitamin C is essential for immune function, collagen synthesis, and antioxidant protection
- Most people struggle to get enough vitamin C through diet alone
- Regular vitamin C can lead to improved overall health and well-being
Why Vitamin C matters
Vitamin C isn't just another vitamin—it's an essential nutrient your body can't produce on its own. It's crucial for your immune system, skin health, and your body's ability to heal.
However, within the National Institutes of Health data set, approximately 7% of Americans are vitamin C deficient.

That translates to millions of people with compromised defenses and slower recovery times.
VitaRx Tip
Unlike most animals, humans can't produce vitamin C endogenously, making it an essential dietary component that must be obtained through food or supplements.
What happens when you fall short?
Common deficiency symptoms include fatigue, slow wound healing, weakened immunity, and joint pain. In severe cases, scurvy can develop.

So why does deficiency remain common in modern diets?
Our modern diets often lack fresh fruits and vegetables—primary sources of vitamin C. Even if you're eating your greens, cooking can destroy up to 80% of the vitamin C content. Add in stress, smoking, and environmental toxins, and you've got a recipe for depletion.
It’s worth knowing that specific groups—including smokers, pregnant or breastfeeding women, and people recovering from surgery or burns—have even higher vitamin C needs.
Smokers, for example, need an additional 35 mg of vitamin C daily due to increased oxidative stress.
Quick recap—here’s why some people need more:
- Smokers: Increased free radicals from smoking use up vitamin C faster.
- Pregnant/breastfeeding women: Extra vitamin C supports baby’s growth and milk production.
- Recovery (surgery/burns): Healing tissues rapidly consume vitamin C stores.
Recommended Daily Allowances (RDA)
Age | Male | Female | Pregnancy | Lactation |
---|---|---|---|---|
0–6 months | 40 mg* | 40 mg* | ||
7–12 months | 50 mg* | 50 mg* | ||
1–3 years | 15 mg | 15 mg | ||
4–8 years | 25 mg | 25 mg | ||
9–13 years | 45 mg | 45 mg | ||
14–18 years | 75 mg | 65 mg | 80 mg | 115 mg |
19+ years | 90 mg | 75 mg | 85 mg | 120 mg |
Smokers | Individuals who smoke need 35 mg/day more vitamin C than nonsmokers. |
Infants’ needs are based on average intake from breast milk.
What if you exceed the RDA? Vitamin C is water-soluble, so your body typically excretes any excess, but mega-doses (over 2,000 mg daily) can cause digestive upset like diarrhea or cramps.
Eating a range of fruits and vegetables each day is a great way to meet your needs—five servings can supply over 200 mg of vitamin C.
