Many customers feel a difference in energy and mental clarity within the first week of consistent use.

How to Take Liquid Thiamine HCl

As a daily supplement, take one full dropper (1 ml) by mouth or mixed into water or juice. Each dropper delivers 100mg of Thiamine HCl. For fastest absorption, hold the liquid under your tongue for 30–60 seconds before swallowing. Take with or without food.

Thiamine HCl vs. Thiamine Mononitrate vs. Benfotiamine

1Herbs offers three forms of liquid Vitamin B1 so you can choose the right one for your goals:

Thiamine HCl (this product) — the most water-soluble and fast-absorbing form. Best for people who want a noticeable energy lift quickly.
Thiamine Mononitrate — a more stable, shelf-friendly form. Best for steady, everyday metabolic support.
Benfotiamine — a fat-soluble form that absorbs differently and stays in the body longer. Often chosen for advanced nerve support.

Not sure which is right for you? Many customers start with Thiamine HCl if they want to feel a difference fast, or switch to Thiamine Mononitrate for long-term daily use.

Frequently Asked Questions

How much Vitamin B1 is in each serving?
Each 1 ml dropper delivers 100mg of Thiamine HCl (Vitamin B1), which is 8,333% of the recommended Daily Value. Vitamin B1 is water-soluble, so any excess is naturally eliminated by the body.

Why is Thiamine HCl faster-absorbing than other forms?
Thiamine HCl (Hydrochloride) is highly water-soluble, which means it dissolves and enters the bloodstream more quickly than fat-soluble forms like Benfotiamine. The liquid format speeds up absorption further compared to pills or capsules.

Can I take Liquid Thiamine HCl every day?
Yes. Most adults take one full dropper daily. Because B1 is water-soluble, your body uses what it needs and eliminates the rest. Always check with your doctor before starting any vitamin supplement, especially if you are pregnant, nursing, or on medication.

What is the difference between Thiamine HCl and Thiamine Mononitrate?
Both are water-soluble forms of Vitamin B1. Thiamine HCl is slightly more soluble and absorbs faster, making it a good choice for those who want quick results. Thiamine Mononitrate is more shelf-stable and is widely used in food fortification.

Is this product vegan?
Yes. Liquid Thiamine HCl from 1Herbs is vegan, non-GMO, and contains no animal-derived ingredients. The sweet taste comes from coconut-derived vegetable glycerin.

Is it safe to take with other B vitamins?
Yes. Thiamine works synergistically with other B vitamins. Many customers also take our Liquid B-Complex with Vitamin C for complete B-vitamin support.
