Key Benefits and Actions*

  • Immune system support
  • Respiratory and lung support
  • Healthy oxidative stress response

A healthy immune system fights off bacteria, viruses, and fungi. It also responds appropriately to the inflammation created from these defense actions. To do this effectively, your immune system requires specific nutrients.*

Immune Intensive provides a powerful dose of 5 essential immune support nutrients. This unique liquid supplement is emulsified for optimal absorption.*

Each ingredient plays a specific and targeted role to support your immune system:

  • Vitamin A — Plays significant roles in respiratory and lung health, normal inflammatory signaling, and healthy immune system defenses.1*
  • Vitamin C — Supports healthy histamine regulation, inflammatory responses, immune system defenses, and respiratory health.2 *
  • Vitamin D — Plays important roles in cells that control the immune system.3*
  • Zinc Supports the healthy and normal functioning of cells that regulate immunity, inflammatory signaling, and oxidative stress.4*
  • Vitamin K Anytime you consume supplemental vitamin D, you should ensure adequate vitamin K levels to promote healthy calcium regulation. Vitamin K has been shown to support normal calcium balance when taking vitamin D. It also plays important roles in modulating normal immune cell function.5 For a pure vitamin D and K product, check out our best-selling Optimal Vitamin D3+K2 Drops.*

Immune Intensive is formulated as an easy-to-take, bioavailable liquid. The nutrients are emulsified and micellized using non-GMO sunflower lecithin, which may increase your body’s ability to absorb them.*

The convenient bottle makes it easy to travel and take on the go. Start school, work, or a vacation with the confidence and tools you need to support a healthy immune system!*

Immune Intensive is here when you need it. During times of higher stress, such as the changing seasons or when you’re traveling, maintaining healthy immune defenses is critical. Now, it’s easier than ever to support your immune system through anything life throws your way.*

2nd bottle and very happy

I have been switching to Seeking Health products as I run out of other brands, as they were only available at other online vendors. As I am severing my ties from that company, I have chosen to use USA made products and order directly from the manufacture.

I love the consistency of quality, free shipping auto ship and rewards!! This product replaced two others plus gives K. I feel my immune system is running at peak performance thanks to seeking health and Immune Intensive.

Best Stuff Ever!!!

My family and I call Immune Intensive “Liquid Gold”…it’s that valuable! I have it on autoship every 60 days, so my family of 6 will never be without. The worse thing is to not have it on-hand when you need it! Every minute counts when you’re sick! Immune Intensive cuts the amount of sick days in half, at least. I have told several friends about this product and they are in love with the results as well…not in love with the flavor, as it tastes like a mouth full of vitamins. But when you’re sick (or trying to avoid sickness) who cares about the flavor?! I add a drop of orange essential oil to my bottle and all is well. This one bottle has eliminated the need for 5 individual bottles of each immune boosting supplement. Pro Tip: Do NOT take on an empty stomach…eat a banana or something before taking, or else the zinc may induce nausea. ;) Bottom line: You need this in your arsenal to fight any sickness.

Essential product

Really like the ease of having the essentials: Vitamin A,C,D,K, & Zinc combined in one bottle. For my husband who isn’t always consistent w/taking vitamins/supplements this immune support makes it easy for him!
