Not a reaction. A routine.
Stop playing catch-up with your health.
Your immune system needs its nutrients every day, not just on the days you feel run-down.*
From scramble to routine.
Most of us only think about immune support once we already feel off. Then it's a rush for whatever's in the cabinet, a few days of it, and back to forgetting. Meanwhile, your immune system needed its nutrients every single day.*
- The scramble: reacting after you feel run-down, with whatever's on hand.
- The routine: one packet a day that gives your immune system its daily nutrients, consistently.*
- Why it sticks: no pills to swallow. 60 seconds and you're done.
Why every day matters.
Your immune system works around the clock, and it runs on nutrients. Some of the most important ones are hard to keep topped up from food alone.*
- Vitamin C and B vitamins are water-soluble, so your body doesn't keep a large reserve.
- Zinc has no dedicated storage system in the body.
- Vitamin D is found naturally in very few foods.
NACPRO+ covers all of these within its 22 physician-selected nutrients, in one daily packet.*
Who made it
Made by two doctors. For their own families first.
As doctors, they kept seeing the same pattern: most people only think about immune health once they already feel off.
So they built NACPRO+ as a daily habit instead: 22 nutrients in one packet, not a handful of pills.
Before selling a single box, they shared the first 1,000 packets with fellow healthcare workers.
Dr. Liu is also the Healthy Immune Doc on YouTube, followed by 660,000+ subscribers.

Frequently asked questions
Straight answers about our formula, testing, and subscription.
Why take immune support every day?
Your immune system works every day, and it relies on nutrients like vitamin C, vitamin D3 and zinc to support normal function.*
Several of these aren't stored in large amounts: vitamin C and B vitamins are water-soluble, and the body has no dedicated storage system for zinc. Vitamin D is found naturally in very few foods. That's why steady daily intake matters more than reaching for something once you already feel run-down.
NACPRO+ puts 22 physician-selected nutrients into one 60-second daily habit, so consistency is easy.
Not a reaction. A routine.
Is NACPRO+ worth the price?
On a subscription, NACPRO+ works out to $2.35 to $3.16 a serving for your first order, depending on box size. The popular 60-serving box is $2.44 a serving. That covers 22 nutrients that would otherwise mean several separate bottles.
And with our 60-day money-back guarantee, even on opened boxes, you can find out risk-free.
What does NACPRO+ taste like?
Bright citrus up front, with a slightly earthy finish. That earthiness comes from real botanicals in the 22-nutrient blend, like cordyceps, turmeric and bromelain.
We use only natural flavors and don't mask the ingredients with artificial ones, so the taste can take a few days to get used to.
Tip: 🍊🍍 Mix your packet with orange juice, pineapple juice or your favorite drink for a smoother taste.
What goes into your body matters most. That's why we put physician-formulated nutrition ahead of artificial flavoring.
Not a reaction. A routine. 💛
