Benfotiamine is a lipid (fat) soluble form of vitamin B1 (thiamine). It is found in very small quantities within roasted, crushed garlic and other vegetables such as onions, shallots, and leeks.

Methylcobalamine (called Methyl B12), is the form of vitamin B12 that can be directly utilized by the body. It is available in the RHP Nerve Support Formula in quantities nutritionally needed by the body to help repair itself. Methyl B12 can be taken orally and is immediately available to the body much like injectable vitamin B12.

No, they will not.

It has been known for some time that increased levels of Thiamine (vitamin B1) in the blood stream are very effective in supporting the nervous system. Unfortunately, the oral intake of vitamin B1 does not greatly increase the levels of B1 in the blood stream. Previously, the way that blood stream levels of B1 were increased was through periodic intravenous feeding or through injections every few weeks.

The reason that methods like this had to be used is that Thiamine (sometimes spelled Thiamin), like all of the B vitamins, is water-soluble. Thiamine cannot be stored in the body and flushes out within 4 to 5 hours. Oral intake of Thiamine over 5 mg results in greatly reduced bioavailability and immediate flushing from the body (this is why urine frequently turns yellow when taking larger doses of B vitamins).

The most common type of vitamin B12 used in vitamin supplements is called Cyanocobalamine. Taking Cyanocobalamine can result in absorption of as little as 1/2 of 1{1484f3e50043c16698cc4bb64e12d251cc621d94ba9a0c7b684292b9db1af8e8} of the amount taken, which makes it almost impossible to get enough vitamin B12.

Additionally, the body must convert the Cyanocobalamine (which cannot be used by the body) to a form of vitamin B12 the body can use called Methylcobalamine. Unfortunately, as the body gets older it starts losing this ability to convert Cyanocobalamine to Methylcobalamine.
