Review: Great for after extended fasting. - I used this after extended fasting and found it to be a good product. I will buy it again.
Review: Excellent for helping with recovery from alcoholism. - After several years of heavy alcohol abuse, a few weeks ago I was able to get sober with the help of my physician. I did a lot of research on how to correct any damage or deficits caused by the alcohol and found that, among other things, I had many of the symptoms of thiamin deficiency. I also read that alcoholics don't absorb it through the intestines very well, and so I bought this pure powder supplement, hoping to overcome that problem. I rubbed the powder under my tongue because I know that from there it can be absorbed directly into the bloodstream, bypassing the GI tract. It is very bitter on the tongue but by rubbing it under the tongue, holding it there for a couple of minutes, and then washing it down with a sweet drink I can avoid tasting it. The first thing I noticed, the very first day, was that that evening I felt sleepy and for the first time in months? years? I fell asleep quickly and naturally without the aid of alcohol, sleeping pills or melatonin. I slept soundly for nine solid hours and woke up feeling refreshed and energetic. The second thing I've noticed (after three days of use) is that I have a lot more energy, and that the chronic swelling that had developed in my feet and ankles has disappeared despite the fact that, if anything, my intake of sodium has increased since I became sober. I can't wait to see what the next few weeks bring!

### ⭐⭐⭐⭐⭐ Using It For My Pygmy Goat With Thiamine Deficiency
*by C***S on January 18, 2017*

I'm so glad I found this store on Amazon! I have a sick goat. She is 12 yrs old and all of her teeth are loose. Goats only have a bottom layer of teeth, only gums on top, no teeth. She has been unable to chew hay properly, and goats need hay for digestion and proper function of their rumen (they have multiple stomachs). And if the rumen doesn't function properly the goat ends up with a Thiamine deficiency. And that in turn causes bloat, a large distended belly. For years I've been buying thiamine injections from my veterinarian on an emergency basis. Recently I decided to research giving her a daily thiamine supplement and ran across BulkSupplements. After reading reviews and realizing this powder is very potent and clean, I decided to give it a try. I also bought B12 powder since the vet always sends an injection with that too. I've been giving "Lily" a quarter teaspoon of each powder mixed in with powdered nursing milk and she loves it. She's been bloated for about a week and had not responded to injections, but after giving her the powder once a day for the past two days she seemed to be more active today. I'm not positive this will alleviate the problem with my goat, but I can definitely say I'm very pleased with the quality and price of these powders. This is a great option for those of us who prefer to take charge of our (and our pets) health, and take advantage of quality supplements. Five stars for a clean, quality and affordable option! Pic of Lily attached.
