Natural Vitamin B1(60 capsules)


Boost your energy production and mood with Dr. Berg Natural Vitamin B1. This formula is made with highly bioavailable allithiamine, a unique lipid-soluble form of vitamin B1 found in onion-family vegetables. Whether you have a B1 deficiency or you need a boost of mental and physical energy, Natural Vitamin B1 is a perfect tool for the job. Each bottle contains 60 capsules.




Vitamin B1 is essential for a healthy body. It helps promote energy production, normal blood sugar levels, a healthy cardiovascular system, concentration, and a lifted mood. Food and beverages with tannins and sulfites—including tea, coffee, red wine, and dried fruit—can block the absorption of vitamin B1. In turn, this can lead to vitamin B1 deficiency.

Synthetic vitamin B1 supplements are difficult for your body to absorb and utilize. This makes replenishing vitamin B1 a serious challenge for those using cheap, low-quality supplements. That’s why we created an all-natural source of vitamin B1 that actually works.


Dr. Berg Natural Vitamin B1 formula is made with highly bioavailable allithiamine, a unique lipid-soluble form of vitamin B1 derived from vegetables in the onion family. Allithiamine is superior to thiamine because it can be easily transported through cell membranes, allowing for faster and better absorption and benefits.

Each bottle contains a 60-day supply of easy-to-swallow vegan-friendly vitamin B1 capsules. Our products contain zero fillers, unnecessary additives, or harmful chemicals. Whether you have a B1 deficiency or you want to boost your mental and physical energy, Natural Vitamin B1 is a perfect supplement for you.

Boosts energy production

You need vitamin B1 to produce ATP, the body’s primary energy-carrying molecule. The superior bioavailability of allithiamine in Natural Vitamin B1 gives you an incredible boost of energy.

Regulates blood sugar levels

Vitamin B1 supports normal blood sugar levels by boosting glucose metabolism. Natural Vitamin B1 is perfect for those who need extra blood sugar regulation.

Supports optimal heart function

Vitamin B1 is key to the production of acetylcholine, a neurotransmitter that helps the body to pass messages between nerves and muscles. Without this communication, the heart can’t function the way it should.

Regulates blood pressure

Vitamin B1 helps regulate blood pressure levels. It can potentially increase blood pressure levels in those with low blood pressure due to vitamin B1 deficiency.

Protects nerves

Vitamin B1 helps with the development of the myelin sheath, a coat that wraps around nerves to protect them from damage and death.

Improves memory and concentration

Vitamin B1 is important for reducing brain fog, increasing concentration, and supporting memory. The allithiamine in Dr. Berg Natural Vitamin B1 more easily passes through the blood-brain barrier to help you reach optimal levels quickly.

Stabilizes mood and may reduce depression risk

Low vitamin B1 has been linked to low moods and an increased risk of depression and anxiety. Allithiamine helps support normal levels of vitamin B1.

Supports healthy vision

Low vitamin B1 is associated with cataract development and diabetic retinopathy. Allithiamine is a great way to help support healthy eyes and vision.

Promotes normal digestion

Vitamin B1 regulates the production of hydrochloric acid in the stomach, which is crucial for maintaining healthy digestive function.
