Benfotiamine

What is benfotiamine?

Benfotiamine is a derivative of vitamin B1 (thiamine) that is fat-soluble, which means it is better absorbed and utilized by the body than traditional thiamine supplements. It is used for treating and preventing various health problems.

How does it work?

Benfotiamine works by boosting the levels of thiamine in the body. It improves the functioning of the nervous system and helps to prevent damage to the nerves and blood vessels caused by high blood sugar levels.

What are the active ingredients that are important for its medicinal properties?

The active ingredient in benfotiamine is benfotiamine.

What forms does it come in?

Benfotiamine comes in capsule or tablet form.

What if there’s an imbalance or deficiency?

A deficiency of benfotiamine can cause nerve damage and other health problems, particularly in people with diabetes.

When was it first used for medicinal purposes?

Benfotiamine was first used for medicinal purposes in the late 1960s.

What does Benfotiamine help with?

• Diabetic nerve pain (peripheral neuropathy): This is benfotiamine's best-supported use. High blood sugar over time damages the nerves in your feet, legs, and hands — causing pain, burning, and tingling. Benfotiamine helps shield those nerves by blocking the sugar-related damage pathways that cause the problem in the first place. Multiple clinical trials show meaningful reductions in pain and symptom scores with consistent use.
• Numbness and tingling in hands and feet: Whether from diabetes or alcohol-related nerve damage, benfotiamine helps restore nerve signaling by ensuring nerve cells have enough active thiamine to function properly. Users often notice gradual improvement in sensation and reduced pins-and-needles over several weeks of use.
• High blood sugar complications: Chronically elevated blood sugar triggers several damaging processes in blood vessels and organs. Benfotiamine is one of the few compounds shown in human studies to block multiple of these pathways simultaneously, helping protect blood vessels, nerves, and kidneys from long-term sugar damage.
• Kidney stress from diabetes: Early research suggests benfotiamine may help protect kidney cells from the inflammatory and structural damage caused by high blood sugar. It appears to reduce markers of kidney stress in people with diabetes, though this area needs more large-scale study.
• Alcoholic neuropathy: Heavy alcohol use depletes thiamine and damages peripheral nerves. Benfotiamine has been used clinically — particularly in Europe — to restore thiamine levels and ease nerve pain in people with alcohol-related neuropathy, with some controlled trial evidence supporting benefit.
• Memory and cognitive decline: Thiamine deficiency is linked to cognitive decline, and some Alzheimer's research suggests that thiamine metabolism is disrupted in the brain. Early clinical work with benfotiamine shows it may help slow cognitive decline in people with mild impairment, likely by improving energy metabolism in brain cells.
• Vitamin B1 deficiency: For anyone struggling to correct a thiamine deficiency through regular supplements, benfotiamine is a practical upgrade — it achieves much higher tissue thiamine levels at similar oral doses and is well tolerated long-term.
• Eye damage from diabetes (retinopathy): High blood sugar can damage the tiny blood vessels in the retina, risking vision over time. Animal studies strongly support benfotiamine's protective effect on retinal vessels, and the same mechanisms are thought to apply in humans, though large human trials specifically for retinopathy are still limited.

What can it help prevent?

• Diabetic retinopathy
• Diabetic nephropathy
• Diabetic peripheral neuropathy

Which foods are rich in it?

Benfotiamine is not found in significant amounts in foods. It is synthesized in a laboratory.

What are possible side effects?

• Nausea
• Headache
• Diarrhea
• Constipation

What’s the recommended daily dose?

The recommended daily dose is 300 to 600 mg per day, divided into two or three doses.

How many days does it take to work?

It may take several weeks to several months to see improvement in symptoms.

What time of day is best to take it?

It is best to take Benfotiamine with a meal in the morning or afternoon.

Is it best to take it with or without food?

It is best to take Benfotiamine with food.
