This product was recommended by Dr Bernstein the eminent diabetes specialist in his book "The diabetes solution." It was on this advice that I started taking Sambucol regularly and I have noticed that I have had significant changes int he way that I respond to catching a cold - if I take it at the start of symptoms I often do not proceed onto getting a cold, if I delay then the cold is minimal and resolves much more quickly than it previously did. I therefore recommend it without hesitation. It does not impact on my blood sugars either.
