How to Take Liquid Thiamine Mononitrate

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

Thiamine Mononitrate vs. Thiamine HCl vs. Benfotiamine

1Herbs offers three forms of liquid Vitamin B1 so you can choose what works best for you:

Thiamine Mononitrate (this product) — the most stable, widely used form. Best for everyday energy and metabolic support.
Thiamine HCl — slightly faster-acting and water-soluble. Good for people who want quick absorption.
Benfotiamine — a fat-soluble form that absorbs differently and stays in the body longer. Often used for advanced nerve support.

Not sure which is right for you? Most customers start with Thiamine Mononitrate because it is gentle, affordable, and effective for daily use.

Frequently Asked Questions

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

Can I take Liquid Thiamine Mononitrate every day?
Yes. Most adults take one full dropper daily. 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 Mononitrate and Thiamine HCl?
Both are water-soluble forms of Vitamin B1. Thiamine Mononitrate is more shelf-stable and is commonly used in food fortification. Thiamine HCl is slightly more soluble in water and can absorb a bit faster. Both are effective; many people choose Thiamine Mononitrate for its stability and reliability.

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

How long until I notice results?
Many customers report feeling more energy and mental clarity within 1–2 weeks of daily use. Because liquid drops absorb faster than pills, results often come sooner than with traditional B1 tablets.

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.
