Anorexia Nervosa
Anorexia nervosa is an eating disorder that leads people to be underweight due to an intense fear of gaining weight and distorted body image. People with anorexia nervosa often restrict their food intake, exercise excessively, and develop severe malnutrition, resulting in various complications.

ℹ️ Quick Facts
Quick Facts: Anorexia Nervosa
- Supplements Studied:0
Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
Deficiency common in AN; zinc supports appetite, taste perception, and mood; supplementation may improve weight gain
Addresses multiple micronutrient deficiencies that develop with severe caloric restriction
Supporting Stack (Tier 2)
Deficiency very common; critical for bone health (osteoporosis risk high in AN)
Supports bone health; AN causes significant bone loss that may not fully recover
Support brain health and mood; often deficient due to fat restriction
Support energy metabolism and mood; deficiencies common with restricted eating
Supports cardiac function, bone health, and mood; deficiency can cause serious cardiac arrhythmias
Anemia common in AN; supplement if deficient
How It Works
Anorexia nervosa is a serious eating disorder characterized by severe restriction of food intake, intense fear of weight gain, and distorted body image. It has the highest mortality rate of any psychiatric illness due to both medical complications and suicide. Chronic starvation leads to multiple nutritional deficiencies and medical complications affecting virtually every organ system, including heart, bones, brain, hormones, and immune system.
CRITICAL: Anorexia nervosa requires professional treatment including specialized psychotherapy (particularly Family-Based Treatment for adolescents and CBT-E for adults), nutritional rehabilitation, and medical monitoring. Refeeding must be done carefully to avoid potentially fatal refeeding syndrome. THIS IS NOT A CONDITION TO MANAGE WITH SUPPLEMENTS ALONE. Professional treatment at an eating disorder program is essential. These supplements address nutritional deficiencies that develop but don't treat the underlying psychiatric illness.
* Zinc deficiency is nearly universal in AN and contributes to loss of appetite and taste changes. Zinc supplementation has been shown to improve rate of weight gain and help restore normal appetite.
* Multi-Vitamin/Mineral supplementation addresses the multiple micronutrient deficiencies that develop with severe caloric restriction.
* Vitamin D deficiency is extremely common in AN patients. Combined with the hormonal changes from starvation, this contributes to severe bone loss. Many AN patients develop osteoporosis at young ages.
* Calcium is essential for bone health. AN causes significant bone loss that may not fully recover even after weight restoration.
* Omega-3 Fatty Acids are often deficient because AN patients typically restrict fat. These support brain health and mood.
* B Vitamins support energy metabolism and mood. Deficiencies can contribute to fatigue and depression.
* Magnesium is critical - deficiency can cause dangerous cardiac arrhythmias. Monitor closely during refeeding.
* Iron - anemia is common in AN and may require supplementation.
Expected timeline: Nutritional rehabilitation typically takes months to years. Zinc may improve appetite within weeks. Bone density improvement requires weight restoration and may take years. Psychological recovery often takes longer than physical recovery.
