Hi Paul,
To be honest, this comes off like a bit of a scam. The simplification of the science of nutrition and metabolism is just too much and I am not sure that these claims are supported by the science or by reputable societies (e.g. American Heart Society, American Diabetes Association, etc.). I also don’t find much in terms of recent research articles from him, which throws up a lot of red flags.
I mean, I’m sure he is a decent cardiothoracic surgeon, but that’s not who I would go to for advice on stuff that concerns my metabolism or nutrition. It’s really a completely different system: I would definitely not be commenting on, say, IBS, even though it’s in the same realm of gastroenterology.
While I’m happy that you have had a reduction in your GI flare-ups, it looks like the major component of this stuff is fibre. It might be cheaper for you to increase the amount of fibre in your diet or fibre supplements.
Regarding vitamins, I’m actually finding it difficult to understand what specific vitamins are in there, which makes it hard to tell if they could be liver toxic or not. This is the problem with supplements like this: they are very poorly regulated, so anything could be in there.
Hope this helps,
Thomas
