Tablets are easy to swallow, and at 100 mg I get a good dose without any stomach upset. Started taking them for energy support and definitely notice a difference in my mood.

I’ve been taking these B-1 tablets for a month now and my energy feels more stable throughout the day. The 100 mg dose is just right for my needs, and the tablets are easy to swallow.

These tablets are a great value for the dosage—100 mg of thiamin hydrochloride is exactly what I was looking for. I’ve noticed a real difference in my energy levels since starting them.
