I've started taking these alongside my thyroid medication and have seen an improvement in energy levels, not massive but good enough. My mood has improved too, so I'm happy with making this choice.

I cannot give a full review as my first bottle arrived late and I have not finished it yet. However, I can say that I had a very positive reaction within the first two weeks, then,sadly, back to how I felt before starting the first bottle. I did order three more bottles,hoping that I will get that first response as from the first bottle, following your advice. Sadly, it has not happened yet. I will be starting the next bottle in a few days time when the first bottle runs out, so am hoping for a more positive outcome.

It made such a big difference
After taking Lung Detox for a week, noticed a definite improvement in my breathing capacity (I have COPD). Truthfully, I am probably going to have to take it forever since I don't want to go back to my "former" status.

Taking smart protein has helped me to combat my fatigue and also has curbed my appetite so I've been able to lose weight something I haven't been able to do since I was diagnosed with an underactive thyroid. I'd highly recommend smart protein.
