|---|---|---|---|---|
| Primary stackThe core of this protocol | ||||

| Supporting stackListed as additions to the core | ||||
| Vitamin D | Amount listed: 2,000–4,000 IU daily (test and treat deficiency, may need higher doses) | Deficiency very common; critical for bone health (osteoporosis risk high in AN) | Not graded yet | |
| Calcium | Amount listed: 1,000–1,500 mg daily from diet and supplements | Supports bone health; AN causes significant bone loss that may not fully recover | Not graded yet | |

How this protocol works
In plain language
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.
