Our #1 best-seller is the NACPRO+ Triple the Power — 60 Servings Daily Immune Supplement — and it's easy to see why.

Formulated by physicians with 22 carefully selected nutrients, every packet delivers five powerful benefits:

🛡️ Immune Defense — powered by NAC, Quercetin & Elderberry
⚡ Clean Energy — no caffeine, no crash
🧠 Mental Clarity — cellular-level antioxidant protection
🌿 Healthy Inflammatory Response — stay active and comfortable
🔬 Everyday Cellular Protection — antioxidants that defend your cells against oxidative stress

No fillers. No caffeine. Just clean, effective nutrition you can trust.

NACPRO+ is made in the USA in an FDA-registered, GMP-certified facility — formulated with premium, globally sourced ingredients tested for purity and potency.

Our manufacturing meets the highest standards of quality and safety, with every ingredient carefully selected and verified to deliver consistent, reliable results.

NACPRO+ is more than a multivitamin. While most multivitamins are designed to provide general nutritional support, NACPRO+ is a physician-formulated daily immune wellness formula created to support healthy immune function and overall wellness.*

Unlike a standard multivitamin, NACPRO+ combines purposefully selected vitamins, minerals, amino acids, and botanical extracts—including NAC, quercetin, vitamin C, vitamin D3, zinc, turmeric, elderberry, and other key nutrients—into one convenient daily packet.

Each ingredient was selected to work together to support:

✨ Healthy immune function*
🏃 Antioxidant defenses*
❤️ Cellular health*
🌿 Energy production and metabolism*
🧠 Mental clarity and overall wellness*

Many multivitamins focus on providing basic daily nutrients. NACPRO+ takes a more targeted approach by combining complementary ingredients into one physician-formulated daily routine designed for daily immune wellness, not just general nutrition.

Instead of managing multiple supplement bottles, you get one convenient packet that's simple enough to make part of your everyday routine.*

One packet. Every morning. Daily immune wellness made simple.

NACPRO+ is formulated for safe, daily long-term use — it's the immune supplement our own physicians take every day. Using a precise "less is more" approach, key minerals like zinc, magnesium, and selenium are dosed to support healthy immune function, sustained energy, and cellular health consistently, without unnecessary excess.

As with any daily immune supplement, we recommend consulting your physician before starting — especially if you have a pre-existing condition or take prescription medication.*

Some people notice a difference the same day — including smoother, sustained energy and improved mental clarity. Unlike stimulants like caffeine, the effect is subtle because NACPRO+ supports your body's natural immune and cellular systems, not forces them.

Think of it like a smoother ride. You may feel the difference right away, but the deeper immune support benefits build with consistent daily use:

• Days 1–7: Smoother energy, reduced brain fog, improved mental clarity
• Weeks 1–2: Immune and cellular support becomes more noticeable
• Week 4+: Many users report meaningful improvement in daily wellness and how they feel overall

Individual results may vary.*

NACPRO+ was created by two board-certified physicians who saw firsthand how critical daily immune support had become.

Dr. Jia Yia Liu, a board-certified Infectious Disease physician, and Dr. Lisa Ma, a Primary Care Physician with decades of experience treating low-income and elderly patients, developed the physician-formulated immune supplement in early 2020 — first for themselves, their families, and their medical colleagues.

Instead of relying on a scattered stack of supplements, they combined their clinical expertise into one simple daily immune wellness packet — designed to support immune health, sustained energy, mental clarity, and whole-body wellness from a single, convenient dose.*
