This is not a regular B vitamin formula.

The B1 (thiamine), B2 (riboflavin), B6 (pyridoxine), and B12 (methylcobalamin) comes in their physiologically active form, making them easier to absorb. Only 33% of the patients responded with an increased level of blood pyridoxal-5’-phosphate when receiving pyridoxine HCL the most common form of B6, but the level increased in all when given the pyridoxal-5’-phosphate (Labadarios D, et al. 1977).

Blood levels have shown to be higher from using 5-methyltetrahydrofolate, the metabolite of folic acid as compared to using folic acid (Willems FF, et al. 2004).

Benfotiamine, a Form of Vitamin B1

Research has shown that benfotiamine, a form of vitamin B1, raised blood and tissue levels higher and also remained bioavailable much longer after taking it orally when compared to the more common form of B1 (Loew D, et al. 1996). Benfotiamine has shown to decrease the glucose metabolites that lead to the buildup of certain types of detrimental advanced glycation end products, it protects the retina and it may also protect the kidneys and endothelial cells (Thornalley PJ, 2005, Stirban A, et al. 2006).

B-Complex EF

B-vitamins are important for many reasons and especially the nervous systems but also for the cardiovascular system. A deficiency of Vitamin B6, B12, and folic acid have been linked to elevated levels of the amino acid homocysteine. Increased homocysteine is recognized as a risk factor for several serious conditions.

In a study using MRI markers of neuropathy (abnormality), the researchers concluded that elevated homocysteine and low folate were associated with radiological markers of neuropathology (Scott TM, et al. 2004).

Low folic acid and high homocysteine levels are correlated with depressive symptoms in middle aged individuals (Sachdev PS, et al. 2005, Tolmunen T, et al. 2004).

Elevated plasma homocysteine and low serum folate are independent predictors of the development of dementia and Alzheimer’s disease (Ravaglia G, et al. 2005, Quadri P, et al. 2004).

Low levels of vitamin B6, B12, folic acid and elevated levels of homocysteine predicted cognitive decline (loss of memory) (Tucker KL, et al. 2005).

Deficiency of vitamin B12 has been associated with elevated levels of tumor necrosis factor alpha an inflammatory marker (Scalabrino G, et al. 2004, Peracchi M, et al. 2001, Miller JW. 2002).

High plasma homocysteine concentrations and low concentrations of folic acid and vitamin B6 are associated with an increased risk of extra cranial carotid artery stenosis (Selhub J, et al. 1995).

The carotid arteries are blood vessels going up to the brain. Stenosis of an artery means the artery is obstructed to a more or less degree depending on the severity of the stenosis.

Higher folate intake lowers the risk for peripheral artery disease when compared to lower intake (Merchant AT, et al. 2003).

B-complex EF from BioPro, Inc. also includes the metabolite of folic acid, since not everybody metabolizes folic acid properly.

Folic acid supplementation has shown to lower plasma homocysteine levels and improve insulin and lipid metabolism in healthy postmenopausal women, reducing the risk for cardiovascular disease (Villa P, et al. 2005).

Homocysteine and vitamin B12 has shown to be associated with bone mineral density (Morris MS, et al. 2005).

Increased levels of homocysteine have been associated with increased breast cancer risk in women who have below median levels of folic acid (Goodman JE, et al. 2001).

A hypothesis predicts that adequate intake of folic acid, vitamin B6, and B12 may reduce hyperhomocystemia associated risk for hormonal cancer (Zhu BT. 2003).

There is some evidence that a B-complex EF can improve the symptoms of neuropathy, but it is not as effective as alpha lipoic acid (Ang CD, et al. 2008).
