At Vital Wellbeing, we view the body not as something to be “fixed” but as a dynamic, intelligent system always working toward balance. One of the key players in your body’s self-regulating system is the Natural Killer T cell—a unique type of immune cell that bridges two essential arms of your body’s communication network: the innate and adaptive systems.
Let’s unpack that in a simple way…
Natural Killer T (NKT) cells are a rare hybrid of immune cells that combine features of traditional T cells (which help coordinate and remember responses) and natural killer (NK) cells (which provide a rapid response to potential threats). Think of them as the early responders with a deep memory—ready to act swiftly and wisely when your body creates a health challenge.
Unlike other immune cells that target specific “invaders,” NKT cells can identify a wide range of signals, especially those related to cellular stress or imbalance. They’re crucial for helping your body self-regulate during times of need—whether you’re navigating physical, chemical or emotional stressors; the 3Ts we often refer to.
Why Are They Important?
NKT cells are important because they:
- Help balance immune expression during moments of imbalance or change
- Support the body’s natural ability to maintain cellular harmony
- Contribute to immune surveillance—observing changes at the cellular level
- Respond quickly to imbalances before they become deeply rooted
When NKT cells are well-supported, the body is better equipped to express optimal health—one of the key outcomes we aim to facilitate through all our products, teachings and chiropractic care.
So, how can you support these incredible and vital cells?
Chiropractic adjustments in rhythm. Being healthy means your body can adapt readily and appropriately to stressors – physical (MOVE), chemical (EAT) and emotional (THINK) acting on you. Most people numb themselves with drugs, doing nothing to change their circumstances and hope all will change. This further erodes your health. The question to ask is what is all this stress doing to your body? Well, it’s causing irritation and interference to your nerve system disrupting your innate ability to adapt and function optimally. Taking care of your nerve system with adjustments, in rhythm, will in turn support optimal function of your natural killer cells. Remember a body that can communicate with itself can heal itself!
What about food? Food isn’t just fuel—it’s a communication tool. The nutrients in the food we eat nourish the cell helping to maintain its internal coherence. Choosing foods to support the activity of the Natural Killer T cells is wise.
Here are some whole, real foods known to support the activity of Natural Killer T cells:
- Mushrooms (Shiitake, Maitake, Reishi)
Mushrooms contain beta-glucans—naturally occurring compounds that help support immune expression. They may help activate NK and NKT cells, guiding them to respond more effectively.
How to enjoy: Add shiitake to soups or have both shiitake and reishi in powdered form as a tea or in broths.
- Blueberries
Rich in polyphenols and antioxidants, blueberries are known to support cellular health and optimal immune expression. They help create a nourishing environment for NKT cells to thrive.
How to enjoy: A handful fresh in the morning or blended into a smoothie with magnesium-rich greens like spinch or pumpkin seeds.
- Camu Camu
Yes, one of our foundational Vital Wellbeing products! Raw, organic Camu Camu is the most Vitamin C-rich food on the planet. Vitamin C plays a role in modulating immune cell activity, including that of NKT cells.
How to enjoy: A daily ½-1 teaspoon in a smoothie, water or a freshly squeezed juice supports immune communication while nourishing the body on a cellular level.
- Green Tea
Green tea contains epigallocatechin gallate (EGCG), a compound that has been shown to influence immune function, including the expression of NKT cells.
How to enjoy: Brew 1-2 cups daily and enjoy warm or chilled with a squeeze of lemon.
- Fermented Foods (Sauerkraut, Kimchi, Probiotics)
Fermented foods support gut health, and the gut is a major communication hub for the immune system. A healthy gut environment encourages more balanced immune responses—including the activity of NKT cells.
How to enjoy: A spoonful of raw sauerkraut with lunch or make our kimchi pancakes.
- Magnesium
Our All Natural Liquid Magnesium is a great place to start! It can be ingested, used topically or substituted in baking. Dark leafy foods like kale, chard, and spinach are also rich in magnesium and chlorophyll—two nutrients that assist in cellular communication and immune regulation.
How to enjoy: Lightly steam or sauté with olive oil, or blend into a morning green smoothie.
- Nuts & Seeds (especially Brazil nuts and sunflower seeds)
These contain selenium and vitamin E—nutrients essential for antioxidant protection and immune balance. They help NKT cells stay in a state of readiness without tipping the balance too far.
How to enjoy: A small handful as a snack or sprinkled onto salads
8. Ginger & Tumeric
The curcumin in turmeric can boost the immune system and enhance the production of T-cells. Ginger has anti-inflammatory and antioxidant properties that can help boost immunity.
How to enjoy: Add some garlic and tumeric (along with some black peper to activate the tumeric) to your favourite dishes.
Rather than seeing immune expression as something to “stimulate” or “boost” in a mechanistic way, we focus on supporting the body’s innate intelligence to restore and maintain balance. When your NKT cells are supported with the right inputs—like adjustments in rhythm and nutrient-rich foods—they are better able to carry out their role.
And remember: it’s not just about adjustments and food. Movement, connection, breath, sleep, and the way we respond to life all play a part in creating an environment where NKT cells thrive.
You don’t need extreme measures to support immune health. You simply need to tune in to what your body is asking for. NKT cells are already part of your internal blueprint for balance—let’s support them with adjustments and foods that speak the body’s language. If you’re using our raw, organic Camu Camu or All Natural Liquid Magnesium, you’re already giving your body key minerals and nutrients that help set the foundation for immune resilience. Keep tuning in, keep choosing well, and trust that your body has the capacity for remarkable balance and renewal.
