IV Therapy & NAD+ Infusions

Freeze & Float offers intravenous nutrient therapy alongside NAD+ infusions and vitamin shots, administered by trained staff in a supervised wellness setting. IV drips deliver vitamins, minerals, antioxidants, and hydration directly into the bloodstream, bypassing the digestive system for maximum absorption. NAD+ (nicotinamide adenine dinucleotide) infusions are popular for energy support, cellular recovery, and cognitive performance. Vitamin shots offer a faster, lower-volume alternative for targeted nutrient delivery.

IV therapy at Freeze & Float Spa in Chicago positions the spa within the growing category of integrative wellness centres that pair passive recovery modalities with clinical-grade nutrient administration. The intravenous route offers a pharmacokinetic advantage over oral supplementation: nutrients delivered directly into venous circulation bypass first-pass metabolism in the gastrointestinal tract, achieving near-100% bioavailability compared to the 10–50% absorption rates typical of oral vitamins and minerals. The spa's IV menu includes formulations popular in wellness and recovery settings: high-dose vitamin C for immune support; magnesium for muscle relaxation; B-complex and B12 for energy metabolism and neurological function; and glutathione, the body's master antioxidant, administered either as a standalone push or as an add-on to a drip. Hydration-focused drips containing saline and electrolytes are also offered and are particularly sought after by athletes, travellers recovering from jet lag, and guests experiencing symptoms of acute dehydration. NAD+ (nicotinamide adenine dinucleotide) infusions represent one of the spa's premium IV offerings. NAD+ is a coenzyme central to mitochondrial energy production and DNA repair pathways. Intravenous administration raises cellular NAD+ levels more rapidly than oral precursors such as NR or NMN, and the therapy has attracted attention in longevity and biohacking communities for its purported effects on energy, mental clarity, and cellular resilience. Sessions typically run 60–90 minutes depending on dosage. Vitamin shots — intramuscular injections rather than full IV drips — offer a faster alternative for targeted delivery of B12, vitamin D, or glutathione in a five-minute appointment. These are popular as standalone visits or as an add-on following a float or cryo session. Freeze & Float's River North location, accessible from the Loop and Near North Side, serves both regular Chicago residents and out-of-town visitors seeking wellness services in a premium downtown environment.
