yes, but you (or somebody else in this topic?) felt the effects from 50 mg, this is about 1,5 g of brewer's yeast so even with 50% conversion should I feel the effects. anyway, you didn't answer my question: when should I feel the effects (whether is yeast, spirulina or UMP, TAU)?
As I've reported several times in this and other threads and forums...I've used 1-2 heaping Tbsps. (20-40 grams) of brewers yeast (for the purported nutritional benefits) every single day for at least the last 10 years and I've never felt any of the uridine effects from brewers yeast. Not until I used 250mg of UMP sublingually (for 5 or 6 days) did I experience the magic of uridine. From my experience, if you are planning on using brewers yeast to gain the benefits of uridine....you will not only be disappointed but wasting your time. I know of nobody that has reported uridine mediated benefits from brewers yeast. Like I said, in spite of using substantial doses of brewers yeast daily for at least 10 years, it wasn't until starting on 250mg of sublingual UMP that the fog was magically lifted for me. Read back through the uridine threads and I have posted much more on my experiences of where I was before uridine and where I am now. And like I said, brewers yeast was no benefit to me in comparison to what I've experienced with uridine over the past couple months....it has been amazing for me...of course I had been struggling for a very long time with mental fatigue, brain fog, difficulty concentrating and focusing...just mentally struggling to stay afloat...and the fog has finally been lifted with uridine...I feel like my old self from 10 years ago...like I want to feel and should feel...and it's been a very long time. My suggestion from my experience...save your time and money...use UMP....and UMP is cheap...cheaper than brewers yeast as far as supposed benefit of uridine gram for gram. Of course, depending on where you're at cognitively now and what you're expecting...YMMV
