SISU Cold & Flu Rescue with Ester-C

SISU Cold & Flu Rescue with Ester-C is for the relief of cold and flu symptoms and of upper respiratory tract infection.


  • 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

Anne: a couple of weeks ago

Best thing ever for stopping a cold 'in its tracks'!

Kelly: a few months ago

Great product. My husband takes it as soon as he feels a cold coming and usually stops it in its tracks if he can get a good nights sleep as well. Best price is on Well when it goes on sale.

Whitney: about a year ago

This product really works, great when you feel a cold coming on and this boosts your immune system! Always have on hand in case!

Simone: more than a year ago

Excellent results. I was so impressed I started taking a higher dose of NAC with Vitamin C alongside this, for serious symptoms. One time this product resulted in prevention of a cold setting in. It usually does not prevent the flu for me, but it does reduce the severity and helps reduce phlegm.

Lucille: more than a year ago

I use this product when I feel a cold coming almost always makes me feel better within a day and the cold never gets started. I've recommended it to friends and family and they agree that it really works!

Arcelyn: more than a year ago

Last winter i started taking 2 of these capsules daily and i havent been sick since then. Love this product! All natural & canadian too!

Susan: more than a year ago

Great product for Canadian winters ... Includes helpful herbs that are not usually found all in one tablet with vitamin c. Echinacea, NAC, and andrographis.

Sandra: more than a year ago

I love this stuff. If you feel a little sniffly take it immediately and you can fight that cold head on. I also use it on a regular basis, one per day to help boost my compromised immune system.

Walter: more than a year ago

Hirmand: more than a year ago

I believe that this helped me get over my sickness in a short period of time without having to resort to antibiotics. All about boosting your body to be able to fight off the cold, and I think this helped.
