Common Vitamin Found in Nuts and Seeds: In recent years, the spotlight on nutrition and disease prevention has only grown brighter. But now, a major new study is adding a surprising twist: a simple snack of nuts and seeds may play a role in reducing the risk of skin cancer. Researchers have found that a common vitamin found abundantly in foods like almonds, pistachios, sunflower seeds, and cashews not only boosts overall health but may also protect the skin from harmful UV damage.
The vitamin in question is Vitamin B3, also known as niacin or nicotinamide. This essential nutrient has long been recognized for supporting healthy nerves, skin, and digestion. But recent research shows its role could be far more powerful — potentially reducing the risk of skin cancer and helping people with a history of the disease prevent recurrence.
The findings, published by researchers at Vanderbilt University Medical Center, tracked over 33,000 U.S. veterans. The results were striking: participants who took Vitamin B3 supplements had a 14% lower risk of developing skin cancer, and among those who had previously battled the disease, the risk reduction soared to 54%. This remarkable connection highlights how an accessible and affordable nutrient could make a meaningful difference in the fight against one of the most common cancers worldwide.
What is Vitamin B3?
Vitamin B3, commonly referred to as niacin or nicotinamide, is part of the B-vitamin complex that supports:
- Healthy nervous system function
- Energy metabolism
- Digestive health
- Skin repair and protection
Unlike many nutrients that are harder to source naturally, Vitamin B3 is found in a variety of everyday foods — particularly nuts, seeds, meat, and fish. It can also be taken in supplement form, making it widely available and cost-effective.
The Link Between Vitamin B3 and Skin Cancer Prevention
Skin cancer, including basal cell carcinoma and squamous cell carcinoma, is among the most common cancers globally, often caused by long-term exposure to ultraviolet (UV) radiation. The study found that Vitamin B3 works by supporting DNA repair processes in the skin and reducing the damage caused by UV exposure.
Specifically, nicotinamide:
- Enhances the skin’s ability to repair UV-damaged DNA
- Reduces immune suppression caused by sunlight
- Decreases the risk of abnormal cell growth that leads to cancer
This makes Vitamin B3 a potential game-changer in preventive dermatology.

Study Findings: Numbers That Matter
The Vanderbilt University study involving over 33,000 participants revealed:
- 14% reduction in overall skin cancer risk among Vitamin B3 users.
- 54% reduction in recurrence risk for those with a prior history of skin cancer.
- Stronger protection when combined with regular sun safety habits like sunscreen use.
The results highlight that while Vitamin B3 should not replace conventional protective measures, it may offer an extra layer of defense.
Best Natural Sources of Vitamin B3
If you’re wondering how to get more Vitamin B3 through your diet, here are some of the richest sources:
- Almonds
- Sunflower seeds
- Cashews
- Pistachios
- Peanuts
- Tuna and salmon
- Chicken and turkey
- Fortified cereals
Supplements are also widely available, but incorporating whole food sources ensures additional benefits like fiber, healthy fats, and antioxidants.
Practical Tips for Skin Protection
While Vitamin B3 supplementation shows great promise, experts stress that it should be part of a comprehensive skin protection plan, which includes:
- Applying broad-spectrum sunscreen daily
- Wearing protective clothing and hats in direct sunlight
- Avoiding peak sun hours (10 AM – 4 PM)
- Scheduling regular skin checks with a dermatologist
- Maintaining a diet rich in vitamins, antioxidants, and hydration
Conclusion
This groundbreaking study demonstrates that Vitamin B3, a simple nutrient found in nuts and seeds, can play a powerful role in lowering skin cancer risk. For those who have never faced the disease, it may reduce the odds of developing it; for survivors, it could cut recurrence rates dramatically.
What makes this discovery especially exciting is accessibility: nuts and seeds are affordable, widely available, and already part of many people’s diets. Pairing dietary Vitamin B3 intake with medical supplements (if advised by a doctor) and consistent sun protection measures may offer one of the most effective yet simple strategies in cancer prevention.
In the broader conversation about lifestyle and cancer risk, this study reminds us that sometimes the answers lie not in expensive treatments but in the foods we eat every day. Protecting your skin may be as easy as adding a handful of nuts or seeds to your routine.

FAQs
1. How does Vitamin B3 help prevent skin cancer?
Vitamin B3 (niacin or nicotinamide) supports the skin’s natural ability to repair DNA damage caused by UV rays. It also reduces immune suppression triggered by sun exposure, lowering the chances of abnormal cell growth that can lead to cancer.
2. Can eating nuts and seeds provide enough Vitamin B3 for protection?
Nuts and seeds are excellent natural sources of Vitamin B3, but the amounts may vary. For therapeutic benefits, especially in preventing skin cancer recurrence, supplements are often recommended. A healthcare provider can guide on dosage.
3. Should Vitamin B3 replace sunscreen or other protective measures?
No. While Vitamin B3 can lower cancer risk, it is not a substitute for sunscreen, protective clothing, or avoiding peak sun hours. It should be seen as a complementary measure, not a replacement.
4. Are there any side effects of Vitamin B3 supplements?
Niacin in high doses may cause flushing, headaches, or digestive discomfort. Nicotinamide, however, is a gentler form of B3 and generally well-tolerated. Always consult a doctor before starting supplements.
5. Who benefits the most from Vitamin B3 supplementation?
Those with a history of skin cancer, frequent sun exposure, or weakened immune systems may benefit the most. However, anyone concerned about skin health can consider adding more B3-rich foods or supplements to their routine.
