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.
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.*
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.
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.

"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."
"I've been taking NACPRO+ as a recommendation from a friend. I don't know what's in the packet, but I am able to focus and perform better. 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."
“As a physician, I am impressed. I feel relieved and empowered knowing NACPRO+ helps me stay optimally healthy where my diet fails me."
"NACPRO+ gave me my life back. I had been feeling down and tired for more than a year. Day 5 of taking NACPRO+, my confidence returned and I literally cried because I started to feel normal again."
"I'm not a vitamin taker — but I will take NACPRO+ anytime I feel I need energy or feel like I might be coming down with something."
“There’s not much more to say except NACPRO+ is awesome. I’ve been taking it for about two years and have zero complaints. My primary care doctor, endocrinologist, and nutritionist have all reviewed it and were comfortable with me taking it based on my health history. For me, NACPRO+ has become a supplement I trust and truly love."
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.
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.*
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.*
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.
