Frequently asked questions

How do I know if Andrographis is suitable for me?

We recommend seeking advice from your healthcare professional if you are concerned. Andrographis may cause allergic reactions and / or taste disturbances (including loss of taste) in some people. If you have a severe reaction (i.e. anaphylaxis) or develop any adverse symptoms, stop use and seek immediate medical attention.

How long does it take to notice benefits from Immune Active NK ?

Immune Active NK begins working at different speeds depending on its ingredients. Andrographis may help ease symptoms such as sleeplessness, runny nose, sore throat, and fatigue within 2 to 4 days.¹ Zinc combined with Vitamin C can accelerate recovery by 1 to 3 days, especially when taken within 48 hours of symptom onset.²,³ For longer-term support, green tea extract (EGCG) contributes to immune resilience when taken consistently over a 12-week period, making it ideal for seasonal protection.⁴

What are the key ingredients in Immune Active NK and how do they work?

Andrographis, EGCG, Vitamin C, and Zinc work together to strengthen immune defences in three main ways. First, they stimulate immune cells, helping your body rapidly respond to invading bacteria and viruses. Second, they reduce inflammation, which can otherwise leave you feeling weak and fatigued during immune responses. Lastly, they help block viruses from entering and infecting your cells.⁵⁻⁸
