Telemedicine appointments are available for patients across Florida, including the Tampa Bay Area, South Palm Beach, and North Broward.
Glutathione is a powerful antioxidant produced naturally in the body and present in nearly every cell. Known as the body's "master antioxidant," it plays a critical role in protecting cells from free radical damage, supporting immune function, promoting tissue repair, and driving detoxification — including the removal of heavy metals and environmental toxins. It is essential for cellular health across virtually every organ system, which is why its decline has such wide-ranging consequences.
Glutathione levels decline significantly with age and are further reduced by chronic stress, poor nutrition, environmental toxin exposure, and ongoing illness. That decline is associated with increased oxidative stress, accelerated cellular aging, chronic inflammation, and greater susceptibility to cardiovascular disease, neurodegenerative conditions, and impaired immune response. A glutathione deficiency also directly impairs the liver's detoxification capacity, which affects every other system downstream.
Because glutathione is involved in virtually every cellular process, its therapeutic applications are unusually broad:
Dr. Rubin's preferred delivery method is subcutaneous (SubQ) injection, which bypasses the digestive system entirely and delivers glutathione directly into the bloodstream for immediate cellular availability. SubQ injections avoid the side effects — nausea, flushing, chest pressure — that can occur with higher-dose IV therapy, and they can be self-administered at home after a brief instruction session with Dr. Rubin.
Other delivery methods exist — intramuscular (IM) injections, liposomal oral supplements, sublingual sprays, and inhalation delivery — and Dr. Rubin will discuss the appropriate approach for your situation during your consultation. Oral glutathione supplements are widely available but have poor bioavailability; the injectable methods Dr. Rubin uses are substantially more effective.
Dr. Rubin begins with a full functional medicine evaluation — physical exam, medical and family history, and any necessary testing — to understand what is driving your health concerns before recommending glutathione or any other treatment. His goal is to identify the root causes of your symptoms, not just address them at the surface level.
Glutathione Therapy can stand alone or be combined with other treatments depending on your evaluation results. It is frequently used alongside NAD+ Therapy — the two work through complementary cellular mechanisms — as well as peptide therapy, medical weight loss, and detoxification protocols where indicated. The plan is built around your specific findings, not a standard protocol.
Increased energy is typically felt within hours of the first treatment. Other benefits — improved skin tone, reduced inflammation, better cognitive clarity — develop gradually over weeks to months of consistent therapy.
Frequency depends on your health goals and how your body responds. Dr. Rubin will establish a schedule at your consultation and adjust it over time based on your results and any returning symptoms.
Duration varies based on individual metabolism, age, overall health, and ongoing lifestyle factors — particularly stress and toxin exposure, both of which deplete glutathione. Regular follow-up allows Dr. Rubin to monitor your levels and maintain therapeutic effect.
Yes. Dr. Rubin uses SubQ injections as his preferred delivery method specifically because they can be self-administered at home after an initial instruction session. This makes consistent, ongoing treatment more accessible than clinic-only IV therapy.
Glutathione is a naturally occurring compound produced by your own body. SubQ delivery is non-invasive, non-toxic, and has a well-established safety profile. Candidacy is assessed individually at your consultation.
Dr. Rubin is ABIM Board Certified in Internal Medicine and Geriatrics Medicine and an Advanced Fellow in the American Academy of Anti-Aging Medicine. He spent the first 25 years of his career in internal and geriatric medicine, earning recognition from Castle Connolly Medical as one of the "Top Doctors" in South Florida for four consecutive years.
After completing a fellowship in anti-aging and regenerative medicine, he transitioned to functional medicine — building a practice that addresses the root causes of chronic conditions and uses therapies like Glutathione to support the body's own repair and detoxification systems.
Free consultations are available at both clinics and via telemedicine for patients anywhere in Florida.
