Vitamin B vs. Vitamin C — What's the Difference?

Difference Between Vitamin B and Vitamin C


Key Differences

Vitamin B encompasses a group of eight water-soluble vitamins, each with unique roles, particularly in energy metabolism and nervous system health. Vitamin C, also water-soluble, is primarily known for its role in immune function, collagen synthesis, and as an antioxidant.
Deficiency in Vitamin B can lead to various issues like anemia, fatigue, and neurological problems. Each B vitamin (like B12, B6) addresses specific health aspects. Vitamin C deficiency, famously resulting in scurvy, impacts skin health, wound healing, and immune resistance.
Dietary sources of Vitamin B vary: B12 is found in animal products, while others like B6 are in nuts, bananas, and potatoes. Vitamin C is abundant in citrus fruits, berries, and vegetables like bell peppers and broccoli.
Vitamin B vitamins are key in breaking down carbohydrates, fats, and proteins for energy. Some, like B12, are vital for producing red blood cells. Vitamin C is essential for synthesizing collagen, enhancing iron absorption, and protecting cells from oxidative damage.
Supplementation of Vitamin B is common for those with dietary restrictions (like vegans for B12) or specific health conditions. Vitamin C supplements are popular for general health, particularly for boosting the immune system and skin health.
