Thiamine HCl (Vitamin B1) Powder

Only take 1 a day . No unnecessary additional additives.

Great price for those who like extra B1.

This bulk powder is a real find. Taking extra B1 along with the complete B vitamins really helps with my energy levels.

Good supplement, bad bags.

The zip-locks are too strong, or the connection from lock to bag is too weak. After about 30 times opening, the bag and lock start separating, exposing the product inside to air/moisture, unless you start rolling the top and clipping it. Good service from Bulk Supplements with shipping to Canada, though unfortunately the web site is very slow and buggy.
