Benfotiamine Dosage

Benfotiamine is a manufactured supplement of vitamin B1 (thiamine), which has five times more bioavailable than regular thiamine. The closest form of thiamine, which is similar to benfotiamine is found in genus Allium plants like onions, garlic and leeks.

The configuration of benfotiamine allows it to transverse cell membranes readily, making its antioxidant abilities more usable for the body. Latest research indicates that benfotiamine is valuable in averting a number of oxidative-stress related ailments.

Realistically speaking, the body can only use around ten milligrams of vitamin B1 in thiamine form, in a day. Benfotiamine however, can be taken safely at much higher dosage as it is fat-soluble, not water soluble like thiamine. Most people take 600mg daily, two 150 mg capsules in the morning and two in the evening.

However some people get better results by increasing the dosage as high as 1200mg. In a study to determine the effect of benfotiamine and formation of Advanced Glycation End Products, human participants were given 600mg a day to get a 40% in AGE formation.

People simply have to work out what is best for them, higher or lower dosages, and by being prudent and monitoring their own reactions to the supplement, they can determine the dose which works best for them. Benfotiamine has no side effects at all reasonable daily dosages.

The best way to approach the dose question is to start with the typical recommended amount. The first signs of the supplement working appear two to three weeks after you begin using it, at which point the dose can be adjusted according to needs.

Important: Individuals with thiamine sensitivity need to proceed with caution, if at all. And should consult a medical professional before taking benfotiamine.

Never the less, symptoms of over dosing might include weakness, nausea, sweating, restlessness, feeling of warmth and breathing problems. The skin may also exhibit a bluish colouration. If any of these symptoms are experienced, it is best to discontinue at once.

  1. Hi Andy, I am a 60 year old female who suffers from joint pain, excessive fatigue, fibro mialgia, type 2 diabetes, I have never had extremely high glucose numbers, high for me is 120-150. So I believe I am pre- diabetic. I started taking benfortamine 150 mg after reading about the positive effects on diabetes. I am noticing at I do not feel as tired and my joint pain is less. But best of all, I am enjoying less swelling through out my body. 😊
