Dr. Jia-Yia Liu is a double board-certified infectious disease physician and the Healthy Immune Doc on YouTube, followed by 660,000+ subscribers. Dr. Lisa Ma is a board-certified family physician.
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: 22 physician-selected nutrients in one 60-second packet, instead of a handful of pills.
Before selling a single box, they gave the first 1,000 packets to frontline healthcare workers.
Your immune system works around the clock, and it runs on nutrients. Your body doesn't keep a big reserve of vitamin C, B vitamins or zinc, and vitamin D is found in very few foods. That's why a steady daily routine matters more than a burst after you already feel run-down.*
✅ Ready for your week: Vitamin C, D3 and zinc support normal immune function.*
✅ Energy without caffeine: B vitamins and magnesium support normal energy metabolism.*
✅ Clear-headed through a long day: B6 and B12 support normal nervous system function.*
✅ Antioxidant support: NAC supports glutathione production, one of your body's key antioxidants.*
