I only recently started taking vitamin B-1 which has definitely improved my cognative abilities. But the brand I was using had a horrible taste. I tried adding those pills to my morning breakfast but couldn't hide the taste. Those B-1 pills would only have to just touch my tongue to expose me to that horrible taste.I'm sure there can't be much difference between one major brand of B-1 vs another. All they have to do is just pay attention to the taste.I recommend this brand of B-1

Thiamine hydrochloride has a very poor absorbtion rate at 5 %. Nevertheless, scientific research says clearly that Thiamine hydrochloride is effective as long as you take a large enough dose. Normaly I buy only natural supplements, and being that this product has poor bioavailibility I think it should come in a larger dose per tablet. I take from 500 mg to 800 mg of this product and I must be honest and say that it does have a positive effect on me.

So far good

I take 1/4 to 1/2 a pill when I have a lot of carb food, if I remember. I don't notice any ill effects. I also take a B-12 and a little bit of unfortified nutritional yeast because taking certain B's can deplete other Bs. I ate a lot of sweets (still do sometimes) and those can deplete B's, so this is good insurance. I also thought B1 keeps mosquitos away? Maybe I'm not taking enough but they still like to bite me over my hubby.

Trusted brand with superior quality products.

High quality and potent. I used to have trouble breathing at night when I laid down for bed. Now I take vitamin B1 daily and put 10 drops of thyme extract in my nightly herbal sleep tea before bed, and 15 minutes before my bed-time snack(only eat a light snack before bed), no more breathing problems. "now" is my favorite brand for supplements.

works great if taken right.

I have hypothyroid/ Hashimotos. I struggle with being tired through out the day. My free t3 (active hormone) is always low. After reading and finding out that I should be taking 600mg- 1500mg per day because people with hashimotos are more likely to have issues with low B1, that was a game changer for me. I boosted my b1 to 3 pills a day (300mg), so far along with B complex. I have been able to cut back on taking naps. Its been amazing. I also recently started taking the "now" brand thyroid energy, that seems to help as well. (that one does have zinc in it, as makes my stomach hurt a little if i take it on an empty stomach- zinc always makes my stomach hurt). I actually just ordered 2 more bottles of this b1. This brand seems to work well.
