The familiar symptoms of head and body aches, sinus and chest congestion, coughing and sneezing are all indications that a cold or flu virus has significantly multiplied and your body is working to expel it and destroy affected cells. Over-the-counter drugs are effective at suppressing only some of the symptoms, and often have negative side effects. A better option is to choose natural health products that stimulate the immune system to kill the virus before full-blown symptoms develop.

Sisu Cold & Flu Rescue delivers a combination of four powerful ingredients, Ester-C®, andrographis, NAC, and echinacea, each of them proven in human research to lessen the severity and duration of cold and flu symptoms and boost immune health.

Product Highlights

  • Ester-C® is a unique, non-acidic and easier to digest form of vitamin C clinically proven to last up to 24 hours in the white blood cells of the immune system
  • NAC (N-acetyl-L-cysteine) protects lungs against respiratory infection and reduces phlegm and symptoms of chronic bronchitis
  • The natural sulphur content of NAC is what gives the product its distinctive odour
  • Andrographis is an anti-inflammatory herb that stimulates the immune system and helps against cold and flu symptoms including sore throat
  • High-potency echinacea extract is a powerful immune stimulant and is most effective when taken at the onset of infection
  • Does not have any of the sedative or other side effects of over-the-counter drugs
