THE DAILY DIFFERENCE
Your immune system
works around the clock.
Your support should too.
The Stack Problem
To get what's in a single NACPRO+ packet, you'd need a counter full of bottles and the discipline to take them all, every day. We put it in one packet so you don't have to.
The Potency Problem
NACPRO+ is formulated at the levels two physicians take themselves and recommend to peers, patients, and family. Every amount is deliberate - chosen for clinical reasoning, not to pad a label.*
The Trust Problem
Every ingredient in NACPRO+ is named and chosen for a reason a physician can defend. Everything is transparent, with no hidden percentages. The label is the formula.

Our Origin
Before we sold a single unit, we gave away the first thousand - to nurses, doctors, and the elderly, in the worst weeks of 2020.
I'm Dr. JiaYia Liu, a board-certified Infectious Disease physician. My co-founder, Dr. Lisa Ma, is a Primary Care Physician. We didn't build NACPRO+ in a marketing meeting. We built it for ourselves and for the colleagues we watched walk into 14-hour shifts depleted, exposed, and without support.
We brought together 22 of the most clinically validated immune-supporting nutrients we know - NAC, beta-glucans, Quercetin, Turmeric, Elderberry, Cordyceps, Astaxanthin, PEA, and more - at the potencies physicians actually take, in one simple daily packet.
Then we donated the first 1,000+ units to the people who needed them most. That's who we are, and that's where NACPRO+ began.
The 22-ingredient formula
Every ingredient is named,
dosed, and there for a reason.
Two physicians. Twenty-two deliberate choices.
NAC
NAC. The precursor to glutathione - your body's master antioxidant.
NAC is the amino acid foundation your cells use to produce glutathione, the master antioxidant for cellular defense. It's one of the most clinically studied compounds in physician-led integrative practice - and the reason this formula carries its name.*

Got my life back
"For the past year, I've been struggling with nagging symptoms that wouldn't go away. A friend introduced me to NACPRO+ and told me to just try it. I was skeptical at first, but after taking 4 packets a day for 5 days, my senses came back. I can taste and smell again."

The best part is, I don't get jittery like I do when I have coffee and I am able to go to sleep at night without any issues. Definitely recommending this to my friends and family."

Common questions
Frequently Asked Questions
What makes NACPRO+ different from a regular multivitamin?
NACPRO+ isn’t a regular multivitamin. It’s a 22-ingredient daily immune support system designed with nutrients many people may be missing, in meaningful amounts that work together to support oxidative balance, metabolism, energy production, and the daily essentials your immune system needs to thrive.
A standard multivitamin often combines generic nutrients in generic amounts. Some are too low to close real gaps, while others may be too high. The problem is most formulas are not built around how nutrients actually work in the body or how to optimize the amounts people truly need.
Is it safe to take every day?
NACPRO+ is what our physicians take daily. It was formulated with long-term, sustainable support in mind — using a “less is more” approach to minerals like zinc, magnesium, and selenium, so you can support your body consistently without unnecessary excess. As always, speak with your physician before starting any supplement, especially if you have a pre-existing condition or take prescription medication.*
How quickly will I feel a difference?
Some people notice a difference the same day — including smoother energy and mental clarity. But unlike stimulants like caffeine, the effect is subtle because NACPRO+ is supporting your body’s natural systems, not forcing them.
Think of it like a smoother car ride. You may feel the difference right away, but the deeper benefits tend to build with consistent daily use. Over the first one to two weeks, immune and cellular support may become more noticeable. By week four, many people report a meaningful improvement in how they feel day to day.
Individual results will vary.*
Who are the doctors behind NACPRO+?
NACPRO+ was created by two physicians who saw firsthand how important 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 caring for low-income and elderly patients, developed the formula during the early months of 2020 — first for themselves, their families, and their colleagues.
Instead of relying on scattered supplements, they combined their clinical knowledge into one simple, physician-formulated daily system designed to support immune health, energy, mental clarity, and whole-body wellness.
What does the 60-day guarantee cover?
If you're not completely satisfied with NACPRO+ for any reason, contact us within 60 days of receiving your order and we'll arrange a full refund - no lengthy explanations required. Items must be unused and in their original condition. Reach us at info@nacproplus.com to get started.
How does the subscription work?
Our NACPRO+ subscription makes it easy to stay consistent with your daily immune support routine. You can choose to receive your order *monthly* or *every other month*
Your subscription will automatically renew based on the schedule you select, so you do not have to remember to reorder. You can manage, pause, or cancel your subscription anytime before your next order is processed.
Is it vegan, gluten-free and allergen-free?
NACPRO+ is vegan, Non-GMO, gluten-free, soy and dairy-free, and contains no known allergens. It is made in an FDA-regulated facility in the USA.
