Before your first High-C IV, we'll ask for a blood test called a G6PD screening. If you've never heard of it, you're not alone.
Here's what G6PD is, why it matters and what to expect.
Quick answer: G6PD is an enzyme that protects your red blood cells. People with G6PD deficiency can have a serious reaction, called hemolysis, to high-dose IV vitamin C. A simple blood test checks your G6PD level before your first High-C IV to keep you safe.

What Is G6PD?
G6PD stands for glucose-6-phosphate dehydrogenase. It's an enzyme that helps protect your red blood cells from oxidative damage.
What Is G6PD Deficiency?
G6PD deficiency is an inherited condition in which the body doesn't make enough of this enzyme. It's one of the most common enzyme deficiencies worldwide.
Many people with G6PD deficiency have no symptoms and don't know they have it until they're exposed to certain triggers, which can include specific medications, certain foods and high doses of IV vitamin C.
Why It Matters for High-Dose Vitamin C
At high doses, IV vitamin C can create oxidative stress in red blood cells. In people with G6PD deficiency, red blood cells can't protect themselves well and may break down. This is called hemolysis, and it can be serious.
That's why responsible clinics require a G6PD test before high-dose vitamin C infusions.
What to Expect
- A simple blood draw
- Lab processing, so plan ahead
- Results review with our team
- Your first High-C IV once you're cleared
Tip: Schedule your G6PD test ahead of time so you're ready when you want your first infusion, especially before cold and flu season.
What If I'm G6PD Deficient?
If your test shows a deficiency, high-dose vitamin C IVs aren't safe for you. But you still have options. Our team may recommend:
- A standard IV infusion appropriate for you
- IM vitamin shots
- Other wellness services that fit your goals
We'll also recommend you share your results with your doctor, since G6PD deficiency can affect other medications.
Other Safety Checks
Besides G6PD, our medical team also asks about:
- Kidney stones or kidney disease
- Iron overload conditions
- Pregnancy or breastfeeding
- Current medications
