Vitamin C is much more than a cold remedy. It's one of the most scientifically studied vitamins and a key ally in keeping your body functioning in balance. Although most people know its importance, few understand how fundamental it is for functions ranging from immunity to collagen production, energy metabolism, and protection against cellular aging.

What exactly is vitamin C?

Vitamin C, also known as ascorbic acid, is an essential water-soluble vitamin, meaning our bodies don't produce it on their own or store it to any significant extent. This means we must obtain it regularly through diet or supplements to stay healthy.

It was discovered in the early 20th century after years of research on scurvy, a disease that affected sailors due to a lack of fresh fruit during long voyages. Today we know that vitamin C is essential for more than 300 biochemical functions in the human body.

Rosehip: The natural and effective form of vitamin C

One of the richest and most stable sources of vitamin C is rosehip, the fruit of the rosehip plant. It provides not only natural ascorbic acid, but also polyphenols and plant antioxidants that enhance its effects. This plant form is more bioavailable and remains active longer in the body, making it an ideal option compared to conventional synthetic supplements.

Furthermore, rosehip has been traditionally used in herbal medicine for its immunomodulatory and anti-inflammatory properties. Its inclusion in a formula is no coincidence: it's a decision based on science and centuries of medicinal use.

Key functions in the body

Vitamin C acts on multiple fronts:

• Immunity : Strengthens the function of defensive cells such as T lymphocytes, neutrophils and NK cells.

• Antioxidant : Neutralizes free radicals and protects cells from oxidative damage.

• Collagen production : It is vital for the synthesis of collagen, a structural protein that keeps skin firm, joints flexible, and blood vessels strong.

• Iron absorption : Improves the absorption of non-heme iron (of plant origin), reducing the risk of anemia.

• Energy metabolism : Participates in the biosynthesis of carnitine, a molecule that helps convert fat into energy.

What are the symptoms of a vitamin C deficiency?

Although scurvy is rare today, a moderate vitamin C deficiency is still common and may manifest as:

• Constant fatigue

• Increased susceptibility to infections

• Swollen or bleeding gums

• Dry or dull skin

• Slow healing

• Joint pain

These signs can be easily ignored or attributed to stress, poor diet, or aging, when in fact they indicate a deficiency of this essential micronutrient.

Where is it found naturally?

Vitamin C is found in fresh fruits and vegetables, especially in:

• Citrus fruits (orange, lemon, grapefruit)

• Kiwi

• Strawberries

• Red peppers

• Broccoli

• Rosehip (one of the most concentrated natural sources)

However, its concentration can decrease during storage, cooking, or exposure to heat, oxygen, and light. Furthermore, stress, tobacco, alcohol, and environmental pollution increase our daily needs.

Are all vitamins C the same?

No. Although ascorbic acid is the most common form, the effectiveness of a vitamin C supplement can vary greatly depending on its formulation. Factors such as bioavailability , the presence of natural cofactors , and digestive tolerance make the difference between a functional product and one that goes unnoticed by the body.

For example, recent research has shown that combining vitamin C with zinc, bioflavonoids, and rosehip extract improves its absorption, enhances its antioxidant action, and prolongs its active presence in the body. It's the synergy of these ingredients that transforms a supplement into a true health tool.

How do you know if you need a supplement?

If your diet is low in fresh fruits and vegetables, if you live under high stress, or if you experience frequent fatigue, you may not be meeting your daily vitamin C needs. Smokers or those who engage in intense physical activity also have increased demands.

In these cases, a high-quality supplement can help you maintain optimal levels without relying solely on diet. However, it's important to choose a formula that offers effective absorption and enhanced action , avoiding incomplete products that may have limited effect.
