3. Vitamin C

Vitamin C is an essential nutrient involved in immune function, collagen production, wound healing, and antioxidant protection.

People with diabetes may have increased oxidative stress, although the relationship between vitamin C and diabetes complications is complex.

Eating vitamin C-rich foods is a practical way to support overall nutrition.

Good sources include:

A varied diet usually provides vitamin C for most people.

Although vitamin C supplements are widely available, taking large doses does not necessarily provide additional benefits.

Very high doses may cause digestive discomfort and may not be appropriate for everyone.

People with a history of certain kidney stones should discuss high-dose supplementation with a healthcare professional.

Vitamin C and Wound Healing

Vitamin C is involved in collagen formation.

Collagen is an important structural protein found in skin and connective tissue.

Because diabetes can affect wound healing, adequate nutrition is important.

However, vitamin C alone cannot prevent or treat diabetic foot ulcers.

Any wound, especially on the feet, should be taken seriously and evaluated when necessary.
