7. Riboflavin Deficiency Riboflavin deficiency is known as ariboflavinosis Riboflavin deficiency is known as ariboflavinosisariboflavinosis Riboflavin is continually excreted in urine, making deficiency relatively common (esp. if you consume the minimum needed.) Primary Deficiency- poor vitamin intake Primary Deficiency- poor vitamin intake Secondary Deficiency- intestine has problems absorbing the vitamin; the body being unable to use the vitamin or excessive excretion from the body.
