Your One-Stop Supplement Shop: Immune Support in a Bottle<sup>†</sup>

Seeking HealthA healthy immune system fights off bacteria, viruses, and fungi from your environment and other routes of exposure. But to do all this effectively, it requires a daily supply of very specific nutrients. 

Is your cupboard brimming with immune wellness supplements, leaving you confused about what to take and how to take it? There seem to be thousands of immune support products, herbs, and foods out there, but how do you know which ones are best? Maybe you take vitamin C supplements a few times a year or vitamin D in the winter. Or perhaps you prefer herbal support like echinacea or elderberry. What’s the best option for your times of need?

Seeking Health understands this can all be very confusing and frustrating. That’s why our founder, Dr. Ben Lynch (naturopathic doctor, formulator, and founder of Seeking Health), has created your immune support solution — Immune Intensive.

Nutrients for Immune Health

Let’s start by answering two critical questions:

What nutrients are needed for a healthy immune system?  How can I efficiently get them into my body?

Dr. Lynch has spent years researching the best nutrients for immune system health and what makes the body healthily respond to invaders. His research team discovered 5 specific nutrients that are necessary for optimal immune function.

The Top 5 Immune Support Nutrients 

Amongst the thousands of companies, brands, and products that claim to support your immune system, it can be very confusing knowing what to take! It’s important to understand that immune system health boils down to specific vitamins and minerals. 

It really doesn’t matter what part of immunity you’re trying to support. Whether it’s healthy lung, nasal, and throat support, normal inflammatory reactions, or even a healthy response to oxidative stress, your body relies on specific micronutrients to function. Without enough vitamins and minerals, any additional herbs or detoxes cannot be fully effective.

The following five nutrients are critical for optimal immune function:

  • Vitamin A — Plays significant roles in respiratory and lung health, normal inflammatory signaling, and healthy immune system defenses. 
  • Vitamin C — Supports healthy histamine regulation, inflammatory responses, immune system defenses, and respiratory health. 
  • Vitamin D3  — Plays important roles in cells that control the immune system.
  • Zinc — Supports the healthy and normal functioning of cells that regulate immunity, inflammatory signaling, and oxidative stress.
  • Vitamin K — Plays an important role in modulating normal immune cell function. 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.

Essential Daily Immune Nutrients

These five nutrients (vitamins A, C, D, K, and zinc) are also classified as essential vitamins and minerals. Each of them has an assigned Recommended Dietary Allowance (RDA) by the National Institute of Health. Your body cannot manufacture essential nutrients on its own — you need them from dietary sources on a daily basis — in amounts of at least 100% of the RDA to prevent deficiency issues.

Consistency here is key; the RDA is recommended daily consumption. It is important to have a regimented way of getting these nutrients every day to support healthy immune system function. (1) Without proper amounts of essential vitamins and minerals, your immune system takes a hit. And in this modern age where stress and toxins abound, they are used up faster than ever. 

Each of these five nutrients wears multiple “hats” in your body, beyond supporting your immune system’s basic function. They also play roles in gut health, hormone balance, energy, and much more. Your body even has built-in receptors for essential nutrients.  Yes — it expects them to be present. This makes it that much more important to look at possible deficiencies in vitamins and minerals first, before defaulting to any other immune remedy, such as herbal remedies and detoxes. Your body knows how to run its immune system naturally — it just has to be nourished correctly! (2, 3, 4, 5, 6)

What is the Best Immune System Support?

Research shows that micronutrient deficiencies are worldwide and can compromise the immune system. (7, 8) A Standard American Diet consists of high amounts of processed foods, which can contribute to the problem. (9) However, there are also high levels of toxins and stress in our daily lives, which require essential nutrients for detoxification: another path of depletion. 

Ensuring that your daily diet contains adequate nutrients is crucial. The best way to determine if you have a deficiency is to get lab testing through your qualified health care professional. There are multiple ways to test for micronutrients, including urine, blood, and even saliva tests for markers that indicate deficiency. Once you get your results, your health professional will be able to evaluate what nutrients you might need most. If you want to learn about your immune health status, you can request tests specifically for vitamins A, C, D, K, and zinc.

Though you always want to ensure you're eating a healthy, balanced diet, the fastest and most efficient way to get nutrients to your system is through a high-quality, well-absorbed dietary supplement. This is exactly why we offer Immune Intensive.

Potent Immune Support in a Bottle

Immune Intensive is an optimally-absorbing emulsified liquid with potent doses of the top five immune-support nutrients. Each teaspoon is packed with immune nourishment, going above and beyond the daily Recommended Daily Intake (RDI) for those who desire a high-strength formula:


  • Vitamin A (1,500 mcg or 5,000 IU) 
  • Vitamin C (500 mg) 
  • Vitamin D3 (125 mcg or 5,000 IU) 
  • Zinc citrate (20 mg)
  • Vitamin K (150 mcg) 

And wow, is it an efficient way to get these nutrients! This formula utilizes sunflower lecithin to create a “micelle” (shell) which allows for optimal absorption of the fat-soluble nutrients (A, D, K). Sunflower lecithin emulsifies both the water and fat-soluble ingredients, preventing separation, and providing a consistent amount of each nutrient in every serving. Rosemary extract is added as a natural preservative to prevent any microbial contamination and rancidity.

This product is gluten-free. It’s also free from milk, egg, fish, shellfish, tree nuts, peanuts, wheat, soy, GMOs, artificial colors, artificial flavors, and artificial preservatives. It is clean, pure, and third-party tested for label claims, microbials, and heavy metals.

If you’re tired of guessing, researching, or fumbling with multiple bottles in your cupboard, then Immune Intensive was designed for you! This one-in-all supplement is perfect for those needing high-strength immune support any time of year.

Can Kids Take Immune Intensive?

Immune Intensive is high-strength: this product is intended for adults. Though the FDA classifies children four years and older as “adults,” we highly recommend talking to your child’s healthcare provider for medical advice before using this product for a child of any age, especially younger ones. Fat-soluble vitamins, such as vitamins A, D, and K can present side effects and even become toxic when too high of an amount is consumed. You can see the Tolerable Upper Limits of these nutrients here. Keep in mind that Tolerable Upper Limits also include the amount you are getting from food and other dietary sources in a single day.

How to Take Immune Intensive

Due to its potency, Immune Intensive is intended to be used short-term. Fat-soluble nutrients (vitamin A, D, and K) have Tolerable Upper Limits assigned to them, which should be safely considered.  Immune Intensive should always be taken with food to avoid stomach upset from the zinc. Take 1 tsp (5 ml) by mouth and swallow.  You can immediately follow it with water or your favorite drink mix to enhance taste!

Purity, cleanliness, potency, and intention are behind every step of this product. Now, you can feel confident knowing you have a powerful tool for immune system support in the comfort of your own home.

Other Immune Support Supplements

There are additional supplements that can be supportive of healthy immunity. These include:

Probiotics A healthy gut equals a healthy immune system because the majority of the immune system is located in the gut!  Probiotics can help to support a healthy gut and immune response. Dr. Lynch recommends ProBiota HistaminX, which contains probiotic species that have been carefully selected to exclude those that are known to increase histamine in the gut.

GlutathioneGlutathione is your body's most important and most powerful antioxidant, playing so many different roles in your body. It supports your body’s natural ability to eliminate toxins, chemicals, and free radicals. Seeking Health offers four different glutathione products; learn which one is right for you here.
