The Surprising Role of Vitamin C: More Than Just a Vitamin

Most people associate vitamin C with citrus fruits, believing it to be a simple vitamin essential for health. However, as Dr. Eric Berg DC explains, vitamin C is much more complex and plays a critical role in survival, particularly in times of stress. In this article, we will explore what makes vitamin C unique, its functions in the body, and why maintaining adequate levels is vital for overall health.

Vitamin C: A Stress Survival Molecule

Vitamin C is often misunderstood as just another vitamin, but it acts more like a fire extinguisher in the body. It is utilized during various stressors, including infections, inflammation, injuries, and even emotional stress. Additionally, individuals with high blood sugar or those consuming a high-carb diet may find that vitamin C does not function effectively in their bodies.

The Human Dependency on Dietary Vitamin C

Unlike many animals that can synthesize their own vitamin C, humans have lost this ability and are entirely reliant on dietary sources. Dr. Berg shares his personal experience of being deficient in vitamin C despite consuming foods rich in the nutrient, attributing his deficiency to intense exercise and overtraining, which increases the body's demand for vitamin C.

The Issue with Synthetic Vitamin C

Another important point raised is that 90% of vitamin C supplements on the market are synthetic, often produced from corn sugar in factories, particularly in China. This industrial vitamin C is significantly cheaper to manufacture, leading to a markup in retail prices. When purchasing vitamin C, it is crucial to look for products that contain food complexes rather than just ascorbic acid, which is a synthetic form of vitamin C.

The Chemistry of Vitamin C

Interestingly, vitamin C shares a structural similarity with sugar, allowing it to utilize the same cellular entry points. As a result, high blood sugar levels can interfere with vitamin C absorption, making individuals who consume a lot of carbohydrates prone to deficiency.

Vitamin C and Energy Production

Vitamin C plays a vital role in supporting mitochondria—the energy factories of our cells. It helps manage stress, recycles other antioxidants, and facilitates iron absorption, which is essential for oxygen transport in the blood. Low levels of vitamin C can lead to fatigue, weakness, and decreased endurance.

Oxygen and Vitamin C Connection

Vitamin C is integral in how cells respond to oxygen levels. When oxygen is scarce, the body signals for more vitamin C production. Conversely, low vitamin C can cause cells to suffer from insufficient oxygen, which can exacerbate inflammation and stress in the tissues.

Understanding Subclinical Scurvy

Modern-day vitamin C deficiency often manifests not as the classic symptoms of scurvy, such as bleeding gums, but as what Dr. Berg calls
