Analysis

This tablet provides 100 mg of Thiamin, which is a standard amount for daily health. It also includes 35 mg of calcium, which helps with the structure of the tablet and adds a small amount of that essential mineral.

While it is very affordable, the lack of form specificity (like HCl or Mononitrate) on some labels makes it a bit harder to compare to other brands. However, it is a reliable choice for simple, daily B1 maintenance.

Pros

  • Very low price
  • Includes 100 tablets
  • Includes a small amount of calcium
  • Trusted legacy brand

Cons

  • Form of thiamin is not clearly specified
  • Tablet format can be chalky
  • Lacks high-absorption benfotiamine

Warnings

  • Take with water
  • If you have a sensitivity to binders, check the full ingredient list
  • Keep in a cool, dry place
