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

My husband uses these every night, they help him sleep. They were not available locally so I searched and found your company and we have been very satisfied and appreciate the reminders.
