At Phoenix Men’s Health Center, nutrient IV therapy is used to support general wellness, immune function, and cellular energy. One of the most commonly utilized formulations is the Myers’ Cocktail, a blend of vitamins and minerals administered intravenously for efficient absorption.
What’s in a Myers’ Cocktail IV Therapy?
A standard Myers’ Cocktail typically includes:
- Magnesium
- Vitamin C
- Zinc
- Selenium
- Calcium
- B-vitamins (varies by preparation)
These nutrients are delivered directly into the bloodstream, bypassing the digestive system and allowing for rapid utilization by the body.
The Role of Vitamin C in IV Therapy Immune Support

Vitamin C is frequently added in higher doses for immune-focused IV therapy. Also, research has shown that this plays a significant role in immune cell activity. Immune cells absorb vitamin C and use it in several defense mechanisms, including pathways that generate reactive oxygen species like hydrogen peroxide—compounds used by the immune system to help neutralize harmful microbes.
While different concentrations of IV vitamin C may serve different purposes, general wellness formulations often use moderate doses to support normal immune function.
Vitamin D and Immune Function
Vitamin D is another nutrient often used at Phoenix Men’s Health Center, especially for immune support. In addition, adequate vitamin D levels have been associated with the production of antimicrobial peptides which contribute to the body’s natural defense against viral pathogens.
For patients with low vitamin D levels or increased immune demands, vitamin D injections may be recommended.
NAD for Cellular Energy
NAD is sometimes added to treatment plans as well. It plays a central role in mitochondrial function and cellular energy production. Supportive NAD therapy may help optimize energy levels by enhancing mitochondrial efficiency.
A Comprehensive Approach to Wellness
The clinic emphasizes that vitamins and nutrients often work synergistically, meaning they rely on one another for optimal function. For example:
- Vitamin C functions alongside various B-vitamins.
- Vitamin D’s actions are influenced by other micronutrients.
- Whole foods naturally provide multiple nutrients that interact to support overall health.
Because of this, Phoenix Men’s Health Center highlights that IV therapy is just one tool within a comprehensive wellness plan, and foundational health still begins with a nutrient-dense, whole-food diet.
Nutrition First
While IV therapy can offer targeted support, whole foods remain the most effective long-term strategy for general wellness. Foods rich in vitamins, minerals, and antioxidants provide complex nutritional profiles that are difficult to replicate through supplements alone.
