IV Therapy and Weight Loss FAQ: Your Questions Answered in Blacksburg, VA

When you swallow a vitamin or supplement, it has to pass through your digestive system before any of it reaches your bloodstream. That process reduces how much your body actually absorbs. With IV therapy, nutrients are delivered directly into the bloodstream, bypassing digestion entirely. This results in higher bioavailability, meaning your body has access to a much greater concentration of the nutrient right away. At Cardinal Hydration, all infusions are delivered in a 1-liter Normal Saline base, which also supports electrolyte restoration alongside the targeted nutrients in your chosen drip.

Yes. All clients are required to complete a brief video telehealth medical screening once per year before receiving any IV therapy services. This screening costs $40 and is a non-negotiable safety requirement at Cardinal Hydration. It allows the clinical team to review your health history and confirm that the treatment you have selected is appropriate for you. This step reflects the practice's safety-first approach, rooted in founder Deana Doby's background in emergency care and pre- and post-operative nursing. Once your annual screening is on file, you will not need to repeat it for 12 months.

Both Semaglutide and Tirzepatide are GLP-1 class medications used in Cardinal Hydration's medically supervised weight loss program, but they work through slightly different mechanisms. Semaglutide targets a single receptor pathway and is available in monthly tiers starting at 0.22 mg. Tirzepatide acts on two receptor pathways and is available in monthly tiers starting at 2.0 mg. Both options require a $60 initial consultation and $40 follow-up visits every 90 days to maintain prescription compliance and clinical safety. The right choice depends on your individual health profile, which is assessed during your consultation.

Vitamin injections at Cardinal Hydration are intramuscular, meaning they are delivered directly into the muscle rather than through an IV line. They are a faster option designed for nutrient maintenance between full IV sessions. Available injections include Vitamin B12, Vitamin B-Complex, Vitamin D3, Glutathione, Lipo-Mino with L-Carnitine, Mineral Blend, Tri-Immune, and NAD+ IM. Each targets a specific concern such as energy, immune support, weight management, or mental clarity. Pricing ranges from $16 to $50 depending on the injection selected.

As of July 2026, Cardinal Hydration no longer offers memberships or packages. The practice has shifted its focus to per-session individualized care, which allows the clinical team to assess each visit on its own merits. IV therapy services are priced individually, ranging from $95 for a basic Normal Saline infusion up to $250 and above for NAD+ Therapy. Vitamin injections are priced separately and range from $16 to $50. The annual $40 telehealth medical screening is required once per year for all IV therapy clients.

Cardinal Hydration offers several options depending on the severity and nature of your symptoms. The Myers' Cocktail at $150 includes Magnesium, Calcium, B12, B-Complex, Ascorbic Acid, and Zinc, making it a strong choice for general fatigue and metabolic support. For deeper cellular energy concerns, NAD+ Therapy starting at $250 supports mitochondrial function and DNA repair, which is particularly relevant for persistent burnout. The Recharge drip at $125 provides B-Complex and B12 for a more focused energy boost. A telehealth screening is required before your first session to confirm the right fit for your health profile.
