5 top tips to boost the whole family's immune health  

  1. Support and maintain good gut health with friendly bacteria supplements.

  2. Get more sleep and laugh lots; a lack of sleep and being stressed can suppress the immune system making it easier to succumb to infections.

  3. Vitamin D, the ‘sunshine’ vitamin, facilitates the normal immune system function and could help to reduce your likelihood to get the flu.

  4. Vitamin C is known to be effective in supporting a healthy immune system in both children and adults.

  5. Practice good hygiene by regularly washing your hands and covering your mouth and nose when sneezing or coughing.
