Every day your body responds to training, work, weather and everything else life brings your way. A varied, balanced diet helps you stay resilient and feel your best.
Supplements like AG1 are designed to support your daily routine with a comprehensive blend of nutrients for your immune system – all in one scoop.¹
When your immune system isn’t at its best, you don’t feel your best.
Your immune system is one of your body’s most important foundations – working every minute of the day to keep you balanced, steady and ready for whatever life brings. And when that system feels challenged, it can affect everything: your energy, your focus, your motivation and your ability to show up at your best.
Supporting your immune system means giving your body what it needs to stay strong and responsive, so you can think clearly, move with purpose and be present for the people and moments that matter. Because when your immune system is supported, you feel supported – grounded, capable and ready to take on your day.
Your immune system is always working in the background. And while it’s incredibly capable, it relies on simple, everyday habits to function at its best. The way you nourish your body, how you move and how well you rest all play a role in supporting this essential system.
Your body relies on a wide range of vitamins and minerals to keep its natural defence processes running smoothly – including nutrients like vitamin C, zinc, selenium and others that contribute to the normal function of the immune system.¹
Regular movement helps support overall well-being, circulation and metabolic processes that keep your body functioning at its best. It doesn’t have to be intense – even light, consistent activity can help your body stay resilient and responsive.
Quality sleep is one of the most powerful ways to support your immune system. During rest, your body carries out essential recovery processes that help maintain balance and prepare you for the next day.

To understand what your body needs, let’s first look at how your immune system operates – and why it relies on essential nutrients to do its job.
Your immune system starts with physical and chemical barriers – like the skin, mucous membranes and the gut lining – that block unwanted substances from entering. These surfaces are supported by enzymes, beneficial microbes and immune-active molecules that form your body’s initial shield.
Functioning, intact barriers reduce pressure on the rest of the immune system. Nutrients such as biotin (which helps maintain normal mucous membranes) and zinc and copper (which support normal immune function) help keep these defences working effectively.⁷ ¹
Stay hydrated, support your gut with balanced nutrition and maintain consistent micronutrient intake to support these frontline barriers.
If something gets past its initial barriers, your body reacts quickly with broad, non-specific responses. These mechanisms act fast and don’t need prior learning – helping your body stay steady while other parts of the immune system prepare more targeted support.
These quick reactions give your body time to prepare more specialised support. Nutrients such as vitamin C, zinc, selenium and copper contribute to normal immune function and help protect cells during these high-demand moments.¹ ³
Prioritise rest, manage stress and get steady intake of immune-supporting micronutrients so your body is ready to respond when needed.
Your adaptive immune system learns from experience, builds targeted responses and creates immune “memory” that helps your body respond more effectively in the future. Communication between immune cells helps coordinate these tailored responses across tissues.
This stage is central to long-term resilience. It relies on the formation of new immune cells and precise signalling. Nutrients such as folate, vitamin B6 and vitamin B12 support normal cell division and immune function, helping your adaptive system stay efficient and well-regulated.¹ ³
Support this stage with consistent nutrition, movement, stress management and sleep – and ensure daily intake of nutrients that contribute to normal immune function and cell turnover.
After the immune system responds, it shifts into recovery mode. This phase clears out what’s no longer needed, restores balance and prepares your system for what comes next. Much of this restoration happens during sleep.
Recovery keeps your immune system strong, stable and ready for everyday challenges. Nutrients such as vitamin C, zinc and selenium help protect cells from oxidative stress during this phase and support normal immune function.¹ ³
Prioritise sleep, hydration and steady micronutrient intake to help your body restore, reset and stay resilient.
These Essential Nutrients Support Your Immune System
AG1 includes vitamins and minerals that contribute to the normal function of the immune system – every day.
VITAMIN C
Vitamin C supports various cellular functions of the immune system, helps the ability of immune cells to respond, and protects them from oxidative stress.¹ ³
ZINC
Zinc is crucial for the development and function of innate and adaptive immune cells, supports normal cell signaling in the immune system, and protects cells from oxidative stress.¹ ³
VITAMIN B12
Vitamin B12 plays a key role in the production of new immune cells by facilitating DNA synthesis, and helps maintain normal energy metabolism.¹ ²
VITAMIN A
Vitamin A helps maintain the structure and function of mucosal barriers (like the gut and respiratory lining) and supports the development and function of immune cells such as T-cells.¹ ⁷
VITAMIN D
Vitamin D contributes to the normal function of the immune system by supporting the activity of immune cells such as T-cells and macrophages, and helps regulate immune responses to keep them balanced and effective.
VITAMIN B6
Vitamin B6 is required for the formation and activity of immune cells and supports the production of signaling molecules that help coordinate immune responses.¹
FOLATE
Folate is essential for the production of fast-dividing immune cells and enables DNA synthesis for the body to form new immune cells efficiently and respond to challenges.¹
COPPER
Copper supports the activity of immune cells, contributes to the formation of connective tissue barriers, and plays a role in antioxidant defense.¹ ³ ⁵
SELENIUM
Selenium supports the production of antioxidant enzymes that protect immune cells from oxidative stress and contributes to the normal function of immune cells.¹ ³
