What is high dose vitamin C therapy?
Taken by mouth, the amount of vitamin C the body can absorb is limited. Delivered intravenously, vitamin C bypasses the digestive system entirely and reaches blood concentrations that oral supplementation cannot achieve. It supports immune function, provides antioxidant protection, contributes to collagen production for skin and connective tissue, and assists recovery after illness or intense physical demand.
Who it suits
- People who fall ill frequently or are recovering from infection
- Anyone under high physical or oxidative stress
- Patients wanting antioxidant and collagen support
Important safety note
Screening for G6PD deficiency is required before high-dose vitamin C, and the dose is adjusted for kidney function. Our doctors carry out this assessment as part of your consultation.
After your IV drip
- Drink plenty of water afterwards — around one ounce of water per kilogram of body weight.
- Avoid alcohol during and after the infusion.
- Rest properly so the body can use the nutrients efficiently.
- Avoid smoking after treatment, as it reduces the effectiveness of the therapy.
- Repeat the programme consistently — typically once a week, or as advised by your doctor — for clear results.
Medical supervision at LINNA
Blood pressure and heart rate are measured before every infusion. If anything feels unusual during treatment, the infusion rate is adjusted immediately, or stopped if necessary. Vital signs are checked again afterwards, so you leave the clinic knowing everything is normal. A doctor reviews your health history and any allergies before your first drip.
Frequently asked questions
