Vitamin B5 Deficiency Symptoms

Vitamin B5, also known as pantothenic acid, is part of the B-complex vitamins group. These compounds aid in food conversion from carbohydrates into glucose, according to the University of Maryland Medical Center. They also help to metabolize fats and proteins. Vitamin B5, in particular, is critical in the production of red blood cells and sex and stress-related hormones, often referred to as the anti-stress vitamin. A deficiency in this vitamin is rare as it is available in a variety of foods like avocado, broccoli, beef and pomegranate. However, it does occur and will exhibit symptoms.

Fatigue and Acne

According to Elson Haas in the book, "Staying Health With Nutrition," the earliest sign of a B5 vitamin deficiency is fatigue. Individuals who eat highly refined and processed foods are more likely to experience this condition. Teenagers, in particular, are at risk due to their tendency to eat unhealthy foods with little nutritional value. Haas says the deficiency compounds when acne starts to develop in response to the lack of pantothenic acid. A 1995 study published in the "Medical Hypotheses" by L.H. Leung discusses the link between acne vulgaris and a subsequent lack of vitamin B5. In fact, acne is usually first treated with a vitamin B5 supplement, according to MedlinePlus.

Increased Infections

Haas also notes that individuals suffering from a pantothenic acid deficiency are likely to experience frequent upper respiratory infections. This is due to the decreased production of red blood cells, according to Paul Bedson in the book "The Complete Family Guide to Natural Healing." A lack of vitamin B5 inhibits the body's ability to produce antibodies essential in warding off infection. This results in recurring episodes of illness.

Increased Sensitivity To Insulin

An increased sensitivity to insulin can appear in response to a deficiency in pantothenic acid. According to John Kirschmann, in the book "Nutrition Almanac," vitamin B5 supports healthy cholesterol levels. Decreased levels of vitamin B5 in the blood cannot effectively lower blood fats that can lead to sensitivity to insulin. Diabetics, in particular, benefit from regular absorption of vitamin B5 as it can lower triglyceride levels without affecting blood sugar, Kirschmann says.
