Reduces cravings
A preliminary study found that men who are overweight or had obesity experienced a decrease in food intake and impulsive behavior after taking oxytocin.
Supports weight loss
Naltrexone may increase growth hormone release in people with obesity, leading to an increase in lean body mass and a decrease in body fat mass. Another study found that naltrexone enhanced insulin sensitivity and insulin release in women with polycystic ovary syndrome. Healthy changes in body composition and insulin sensitivity can support weight loss. Researchers are also investigating the potential of oxytocin to decrease body weight and body fat, as well as enhance glucose utilization.
Boosts energy levels
Vitamin B12 deficiency is common. Restoring vitamin B12 supports red blood cell formation. Red blood cells transport oxygen to the body’s tissues. Optimal levels of vitamin B12 can enhance energy levels by improving energy use and oxygen supply to body tissues.

Potential side effects from low-dose naltrexone:

  • Skin rash
  • Stomach ache
  • Headache
  • Joint or muscle pain
  • Nausea or vomiting
  • Fatigue
  • Chest pain or pounding heartbeat
  • Pain with urination
  • Confusion
  • Hallucinations
  • Itching
  • Depression

Low-dose naltrexone is safe for most people.

Low-dose naltrexone should not be prescribed for those who have/are:

  • Uncontrolled high blood pressure
  • Seizures
  • An eating disorder
  • An opioid addiction
  • Pregnant
  • Allergic or hypersensitive to naltrexone

Do not take opioid medication for a minimum of seven to 10 days after starting naltrexone. Do not use a MAO inhibitor within 14 days before or after starting this medication.

Low-dose naltrexone should be used with caution or not at all by those who have:

  • Depression
  • Bipolar disease
  • Mental illness
  • Suicidal thoughts or actions
  • Head injury
  • A brain or spinal cord tumor
  • Diabetes or low blood sugar
  • Low sodium levels
  • Liver or kidney disease
  • Heart disease

  • Heart attack
  • Stroke
  • Drug addiction
  • Alcohol misuse

Low-dose naltrexone (LDN) is used off-label to treat many medical conditions. LDN was first used clinically in 1985 by Bernard Bihari, M.D., a Harvard University physician and director of the Division of Alcoholism and Drug Dependence, SUNY/Health Science Center at Brooklyn, to treat addiction. He noticed that LDN increased endorphins and immune function and began researching its use for patients with HIV.

People use LDN for:

  • Modulating appetite
  • Reducing cravings
  • Decreasing inflammation and pain
  • Improving mood
  • Reducing pain

Actually, the opposite seems to be true. Oxytocin is being tested as a potential treatment for obesity because it:

  • Reduces food consumption
  • Increases energy consumption
  • Reduces cravings for high-carb, high-fat foods

Researchers have found that people with dysfunctional oxytocin signaling may be more prone to obesity.

Oxytocin plays a major role in forming human connections. Under the right circumstances, oxytocin increases:

  • Trust
  • Empathy
  • Positive regard
  • Positive memories
  • Bonding
  • Positive communication

Oxytocin has many potential effects on the brain, including modulating:

  • Anxiety
  • Aggression
  • Stress
  • Fear
  • Depression

Oxytocin is released during the following activities:

  • Childbirth
  • Breastfeeding
  • Sexual activity
  • Light, stroking touch
  • Hugging
  • Cuddling
  • Talking
  • Making eye contact
  • Laughing
