What you eat and drink around your EBOO session is simple, and getting it right makes the treatment smoother. Before EBOO, hydrate well the day before, eat a balanced meal with some protein 1 to 2 hours ahead, and avoid alcohol and high-dose antioxidant supplements like vitamin C that day. After EBOO, keep drinking water, eat light and simple, skip alcohol for 24 hours, and wait a day before resuming high-dose antioxidants. The single most important nutrition rule is the antioxidant timing, because strong antioxidants can work against the ozone.
This focused guide covers what to eat and drink before & after EBOO, food and drink only. For the complete step-by-step prep, see our guide on how to prepare for your first EBOO session, and for the full recovery routine, see our EBOO aftercare guide. Below, we go deeper into just the eating and hydration side.
Good preparation the day before and the morning of makes the session more comfortable and easier on your veins. Here is the before-EBOO nutrition checklist.
This is the most useful thing you can do. Aim for roughly 80 to 100 oz of water the day before, and keep sipping on the morning of your session. Well-hydrated blood flows more smoothly through the circuit and, just as practically, makes your veins far easier to access for the two IV lines. Dehydration is the single most common reason a session is harder than it needs to be.
Eat a real, balanced meal one to two hours before you arrive, and include some protein. Ozone can nudge your blood sugar down during the session, so a meal with protein and complex carbohydrates keeps your energy stable and reduces the chance of feeling lightheaded. A protein shake alone isn’t enough; aim for real food. And do not fast; arriving on an empty stomach is the most common cause of feeling faint.
Avoid alcohol for the 24 hours before your session, since it works against the hydration you are trying to build. Caffeine is fine in moderation, but heavy coffee or energy drinks on the morning of can contribute to dehydration and jitters, so keep it light.
This is the one that surprises people. Skip high-dose vitamin C and other strong antioxidant supplements on the day of treatment. We explain why in its own section below, because it is the most important nutrition rule around EBOO.
Aftercare nutrition supports your body gently as it settles. Nothing strict, just sensible.
Continue drinking water steadily for the rest of the day. If you feel a little drained, an electrolyte drink can help you feel more balanced. Good hydration simply helps you feel your best while your body recovers.
For the rest of the day, favor light, simple whole foods: soups, broths, salads, steamed vegetables, and other easy-to-digest meals. Heavy, greasy, or very sugary meals ask more of your body right when you want to keep things easy. This is not a strict cleanse, just a lighter-than-usual day.
Skip alcohol for 24 hours afterward. You can return to your usual supplements, including antioxidants, the next day rather than the same evening. You don’t need special detox products, teas, or protocols; your body only needs simple food and water.
If you remember only one thing from this guide, make it this one, because it is the piece most people get wrong and the one that actually affects your treatment.
EBOO therapy works partly by creating a brief, controlled oxidative signal in the blood. High-dose antioxidants, vitamin C, glutathione, NAC, and similar supplements do the opposite: they neutralize that signal. Taking a big antioxidant dose right before or on the day of your session can blunt the very effect you are paying for. So keep strong antioxidant supplements off the day of treatment, and resume them the following day.
Note: this applies to high-dose supplements, not to eating an orange or a normal balanced meal; ordinary food is completely fine. Interestingly, some guides tell you to “load up on antioxidant-rich foods to prepare,” and then also tell you to avoid antioxidants on the day. That is contradictory. The accurate version is simple: eat normally, and just skip the high-dose supplements on treatment day.
Patients often ask me what to eat before and after EBOO, expecting a complicated answer, and the honest one is refreshingly simple. You do not need special detox teas, binders, or expensive supplements around your session, despite what you will read. Drink your water, eat a real meal beforehand, keep things light afterward, and hold off on the high-dose vitamin C until the next day. That is the whole list. When someone tells you the food part requires a complicated protocol, they are usually selling the protocol.
Eat a balanced meal with some protein one to two hours before your session to keep your blood sugar stable. Do not fast. Hydrate well the day before and the morning of, and avoid alcohol and high-dose antioxidant supplements on the day.
Yes, generously. Aim for about 80 to 100 oz of water the day before and keep sipping the morning of. Good hydration helps your blood flow through the circuit and makes your veins much easier to access for the IV lines.
Keep caffeine light on the morning of, since too much can dehydrate you. Avoid alcohol for the 24 hours before your session, and for 24 hours after, because it works against hydration.
High-dose antioxidants like vitamin C, glutathione, and NAC can neutralize the oxidative signal EBOO relies on. Skip high-dose antioxidant supplements on the day of treatment and resume them the next day. Normal foods, including an orange, are fine.
Eat light and simple: soups, salads, broths, steamed vegetables, and other easy-to-digest foods. Keep drinking water, avoid alcohol and heavy or greasy meals for the day, and add electrolytes if you feel drained.
No. You do not need special detox teas, binders, or protocols. Simple water and light, balanced meals are all your body needs around a session. Anyone insisting on an elaborate food protocol is usually selling it.
