Dr. Clark Vitamin B1 Thiamine 500mg Supplement -Thiamine B1 Supplement for Healthy Nervous System & Energy Metabolism, Gluten-Free, Dairy Free - 100 Gelatin Capsules

Good product and value. Not too big.

Excellent vitamin supplement for a healthy body

Good product and on time

I chose this thiamine for its high dose, lack of excipients, and promise of quality. But with my last 4 purchases there have been glaring quality control issues that force me to now tell buyers to steer clear of this product. With each bottle there has been one or more thiamine capsules burst open, and every other pill came coated with foul tasting inner capsule contents. I tried to take the supplements anyway and soldier on but the potency also seemed nowhere near what I remembered, and have since switched to a different, lower dose product that gives me the mental and physical boost i remember. This company has lost my business and should probably be reported for poor quality control practices, I don’t believe their products are safe.

but i dint realize this form of b1 thiamine hcl is a synthetic version of b1 not the natural , good for short term use for getting body healed , with high doses for a short term like several months but need to find a natural version . as usual dr clarke store is pure and high quality .

Good way top get a higher amount of thiamine HCl. Many brands are only 100mg

This high-dose B1 is free if harmful excipients. Most B1 supplements come in 50 mg capsules, so it's nice to have a clean, high-dose option available.

Disappointed after taking this pill for months it had less to no affect, I was previously taking two B 250 mg pills, all I wanted was to take one tablet as I use a number of daily supplements. Found better elsewhere.
