Anna Dorothea Hoeck

Dr. Anna Dorothea Hoeck MD (also spelled Anna Dorothea Höck or Anna Dorothea Höeck), is a retired physician in Cologne, Germany. She believes that prolonged vitamin D deficiency or insufficiency coupled with calcium depletion may trigger chronic fatigue syndrome and has found that many mild or moderately fatigued patients improve with supplements of vitamin D3 and other micronutrients. However, she concedes, patients who have had to reduce their activity level greater than 50% due to fibromyalgia and chronic fatigue syndrome have poor treatment outcomes with vitamin D and micronutrient supplemention.
