Longevity Medicine

The phrase “anti-aging” is the application of advanced biomedical technologies focused on the early detection, prevention and treatment of aging-related disease. Chronic disease by definition does NOT occur suddenly rather result of recurring detrimental factors over a length of time.


Chronic diseases (Cancer, Diabetes, Heart disease) and their underlying factors (ex.obesity) account for 3 out of every 4 dollars of U.S Healthcare spending affecting 1 in 3 Americans to the tune of over $1.5 million in annual spend (Miliken, 2014)

Our current model of predicting chronic disease is NOT effective in identifying ROOT cause & often utilizes symptomology or late stage biomarkers in a binary manner to determine health status. We at PHC have identified the key diagnostics to better predict and isolate the pathways of aging so we can target these and promote optimal longevity. We are not about just living longer, but living longer and better.

What if there was a compound that could turn back time, restore energy, improve athletic performance, bring back clarity of thought, reverse depression and help detox alcohol and other toxins in our cells?

There is such a substance. It is called NAD+, and it occurs naturally in every cell in your body.

NAD+ may actually prolong life, protect DNA, slow down aging and help restore function in neurodegenerative illness due to its effects on the genes that govern aging.

Unfortunately, drugs, alcohol, stress, medications, chronic illness and age all contribute to a decrease in our NAD+ stores. As NAD+ goes down, so does our energy. Cells age and deteriorate. Your health falls apart at the very root.

This IV aims to undo that process by replenishing NAD+. Using IV infusion therapy we administer this anti-aging compound directly into your blood circulation so your cells have access to as much as they need.

Between 3-14 consecutive days of NAD+ therapy combined with amino acid infusions, minerals, and B-Vitamins are typically recommended for full effect. Treatment is tailored to your individual needs after a detailed consultation.

PHC uses a premium product of NAD+ called Brain Restoration Plus (BR+) which targets brain health.

Pump up your focus, clarity, and energy so you can tackle anything. Feel great and accomplish more with the ultimate high dose NAD+ experience.
Saturate and support your NAD+ intake by optimizing the function of every cell in your body.

Support on-the-go maintenance and easy access to replenishing NAD levels.  We help you choose what’s best!
