B-1 High Potency 500 mg
Posted by Reviewer1344414 on May 09, 2011
Recommended by my doctor for leg cramps. I cannot tell you enough about this product. Since I have been taking these 3 times a day for quite a while I do not have leg cramps. If on really hot days and I do too much and sweat a lot I will sometimes need to take an extra tablet, and the leg cramps are gone. No sleepless nights walking the floors anymore. I recommend them to anyone I talk to that has leg cramps and cannot get quinine anymore.
For fibro energy

I have fibromyalgia and have been testing various possibilities of supplements that are said to help with the fatigue. I have found that taking high dose vitamin b1 has made a marked difference. I take 4 tablets a day, divided throughout the morning, and it took around 3 weeks to clearly notice the improvement.

Vit B-1 is very valuable for mental stresses. I take 250-500mg daily. Take an equal of Vit C to avoid tooth brittleness. The tablets are pretty large but can be split into 1/2's or 1/4's. Works well for me.

Good quality, high dosage of B-1 and magnesium with no additional vitamins. If you're avoiding b-6, you can take this product. Vegetarian as all Source Naturals products. Pills are compressed, not capsules, and pretty large, which could be a problem for some, but I haven't had any trouble personally.

Using for diabetic nutritional support. If you need a hi-potency B-1..S. Naturals delivers an affordable one.
Great for anxiety

2-3 of these a day is great for anxiety. I also like that they use magnesium citrate because magnesium oxide tends to give me gastrointestinal problems.

I bought this to repel mosquitos, it seems to work so far & the great thing about these is the pills & mg are big enough to cut in two! Makes the bottle last longer. great price cant beat it
