Yes, when properly administered. A peer-reviewed clinical review reports a complication rate of just 0.7 per 100,000 treatments, with nearly all reported issues linked to improper administration rather than the therapy itself. The most common method is major autohemotherapy, where a small volume of blood is drawn, mixed with a precise medical-grade ozone concentration, and reinfused — a closed, controlled process that avoids the risks associated with direct gas injection. At Elysium, ozone therapy is delivered under strict dosing and clinical supervision.

Both aim to improve oxygen availability, but through very different routes. Hyperbaric oxygen therapy saturates the whole body with oxygen via pressurized breathing in a chamber. Oxyvenation instead administers medical-grade oxygen intravenously, in small, carefully controlled doses — working more directly on blood oxygen carrying capacity and microcirculation, without the need for a pressurized chamber. The choice between them depends on what your diagnostics indicate and your specific treatment goals.

For certain nutrients, yes — significantly. Vitamin C is the best-documented example: oral absorption saturates around 500–1000mg per dose due to limited gut transport capacity, while intravenous administration bypasses this limit entirely, achieving plasma concentrations far higher than oral intake alone can reach. This is why IV delivery is used specifically for nutrients where higher tissue concentration is clinically meaningful, not as a blanket replacement for all supplementation. At Elysium, IV protocols are built from your diagnostic panel, targeting the specific nutrients where IV delivery offers a genuine advantage.

There's a growing evidence base for this. A systematic review and meta-analysis of 10 studies (299 subjects) found hyperbaric oxygen therapy significantly accelerated recovery from exercise-induced muscle injury. That said, results are more mixed for general delayed-onset muscle soreness specifically, with some earlier trials showing no added benefit — the strongest evidence is for injury recovery rather than routine post-workout soreness.

It depends on the therapy and the goal. IHHT is typically most effective with a structured course rather than a single session — a controlled clinical trial in Long COVID patients used sessions three times per week over a rehabilitation period to build cumulative gains in walking distance and physical function. IV therapies and single HBOT sessions can produce more immediate, session-specific effects, but sustained results typically require a defined course rather than an isolated visit. At Elysium, frequency is set individually based on your diagnostics and response, not a fixed schedule.
