Vitamin B1 turns your food into energy, delivered by live probiotics.

An essential B vitamin that turns carbohydrates into physical energy and supports healthy nervous system function.

What it is

Vitamin B1 (thiamine) is an essential water-soluble nutrient that your body needs every single day. In supplements, it is usually provided as thiamine hydrochloride or mononitrate for high stability.

Once absorbed, your cells turn thiamine into an active coenzyme that breaks down carbohydrates to create vital cellular energy.

Also known as: Thiamine HCl, Thiamine Mononitrate, Vitamin B1

Key benefits

  • Helps convert food carbohydrates into cellular energy, keeping your body fueled.
  • Supports smooth nerve signals and brain function, so your nervous system stays sharp.
  • Promotes healthy heart muscle performance and circulation.
  • Keeps your stomach and gut muscles working smoothly for comfortable digestion.

Amplified by probiotics

You absorb vitamin B1 in your upper gut, but friendly probiotic bacteria in your lower gut can also make fresh thiamine. Microencapsulated probiotics support these beneficial microbes, creating a steady supply of vitamin B1 that feeds your gut wall cells. Healthy gut acid levels created by probiotics help your gut lining absorb thiamine quickly and easily.

Typical dose

1.1–10 mg/day
