Intravenous Vitamin C Improves Quality of Life

Intravenous vitamin C infusions have a measurable positive effect on people’s quality of life when they are ill or under stress. This is especially welcomed by people living with cancer.

For many years our clinic has been administering a validated international survey for our clients receiving treatment. Our aggregated results mirror the findings of clinical research papers, which mostly happen to use the same survey.

Consistent results across studies

Patients report improved mood, alertness and ability to connect meaningfully with their family and other people around them. Appetite is better. Symptoms like fatigue, pain, insomnia, and nausea are reduced.

Vitamin C offers several likely mechanisms of action for these effects, including its antioxidant properties and involvement in mitochondrial energy production and synthesis of neurotransmitters.
