Primary Deficiency

Primary deficiency is rare because this vitamin is widely available in many foods. SECONDARY DEFICIENCY

This may result from malabsorption syndromes, cancer, liver cirrhosis and alcoholism, hyperthyroidism, congestive heart failure or medicine use, such as OCP, isoniazid, hydralazine, penicillamine, theophylline or MAO inhibitors (Beers & Berkow 2003, Bratman & Kroll 2000, Wardlaw et al 1997).

Although frank deficiency is rare, marginal deficiency appears to be common. One study found that 100% of 174 university students tested had some degree of vitamin B6 deficiency (Shizukuishi et al 1981). A larger survey of 1 1,658 adults found that 71 % of males and 90% of females did not meet the RDI requirements for B6 (Kant & Block 1990).
