Great tonic!
Strath is wonderful. It helped me get over a bad illness which had completely sapped my strength and was on the verge of becoming chronic. I take it fairly regularly now and when I forget I always regret it, as I seem to come down with something or the other. Taken regularly it keeps me well, helps me stay positive and gives me plenty of energy.

It's a great supplement
I was super unsure about whether or not to try this since no one I knew had ever heard about it, and it came from overseas. However, after I got past the taste I feel that it's a great supplement. I used to be the type of person who got sick really quickly and easily, but after taking this for a few months I survived what was one of the worst cold seasons unscathed. Sure there might have been many factors, but I feel that this was one of them. I mostly came to write this review in attempt to describe the taste, texture, color etc. so that people aren't as scared (as I was) to try it since it kind of looks like something Mary Poppins would pull out of her bag... *Texture* Is kind of thick, like a bit thicker than maple syrup but not goopy or chunky. *Color* The color is dark brown, kind of darker and more opaque than maple syrup. *Taste* The taste is reminiscent of wine and beer mixed together with a sweet undertone. I hope this helps someone who is unsure!

Good taste and similar to one I was using with yeast

Bio-Strath originated in 1961
The name Bio-Strath is shortened to Strath in the U.S. for branding purposes. This simplification makes the product name more concise and easier to market while maintaining its identity as a nutritional supplement based on fermented herbal yeast. Strath products are widely recognized for their natural ingredients and health benefits. Bio-Strath originated in 1961 when Fred Pestalozzi founded Bio-Strath AG in Switzerland. Inspired by the herbal yeast preparation developed by Dr. Walter Strathmeyer, Pestalozzi created the company to produce and market this natural supplement. The product has since become a trusted name in nutritional health worldwide.

Welcome to my nightmare
This is the stuff of nightmares...but excellent health. When I was a child my mother used to have to threaten me with my life to take this stuff and I ran oh lord I ran....but not far enough. She would catch me and dang it I had to take it and get well...stamps foot...but I digress, for some reason I thought of this with what the world is going through right now and thought...I want to boost my immune system and this has to be it...something this nasty tasting has to be healthy..right? I will admit it has the same great nauseating taste I remember and it works. It has increased my energy and I feel good. Thanks mom for being abusive and making me take this as a kid and I'm so grateful I can still take this without hurling afterwards. God bless biostrath!

Have used Bio-strath for many years but am having difficulty obtaining it in recent times. I was very pleased to find Bio-strath on Amazon. I hope it will be available ongoing.

This is very healthy very high in B vitamins , 250ml liquid is overpriced, I checked prices at local health stores $24.00 ., Amazon needs to review this pricing.
