LDN Boost FAQs

The Plan
Can you buy LDN over the counter?

Low-dose naltrexone (LDN) is available by prescription only. Naltrexone is an opioid antagonist and is used at a higher dose to treat addictions. In lower doses, it acts as an anti-inflammatory and helps modulate appetite by reducing cravings. LDN is specially formulated by compounding pharmacists.

Does naltrexone have side effects?

All medications have side effects. Most side effects associated with naltrexone are mild and self-limiting. Potential side effects of LDN include:

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
Who should not take naltrexone?

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

  • Heart attack
  • Stroke
  • Drug addiction

What is low dose naltrexone used for?

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
Does oxytocin cause weight gain?

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.

How does oxytocin make you feel?

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

  • Trust
  • Empathy
  • Positive regard
  • Positive memories
  • Bonding
  • Positive communication
Does oxytocin help depression?

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

  • Anxiety
  • Aggression
  • Stress
  • Fear
  • Depression
What activities increase oxytocin release?

Oxytocin is released during the following activities:

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

What is LDN Boost?

LDN Boost Combines Naltrexone, Oxytocin, and Vitamin B12 to Support Your Weight Loss Efforts

Oxytocin and naltrexone both help modulate appetite and reduce cravings by acting on receptors in the brain. People who are vitamin B12-deficient have low energy and depressed mood. Restoring vitamin B12 levels to a healthy range can improve energy levels.

Oxytocin Modulates Appetite and Reduces Food Cravings

Researchers are investigating the role of oxytocin in reducing food intake and decreasing impulsive behavior. Studies show that oxytocin reduces caloric consumption and is involved in several eating behaviors. Oxytocin seems to respond to signals from the gastrointestinal tract and energy stores. It acts on reward, homeostasis, and control systems in the brain to reduce calorie intake, especially for more palatable foods. 

Clinical studies also show that oxytocin increases fat breakdown, which induces weight loss separately from its effect on calorie intake. More clinical trials are underway to further explore oxytocin’s weight loss benefits.

In animal studies, oxytocin also seems to reverse declines in muscle strength and mass associated with aging in both men and women. These findings are exciting for their potential anti-aging benefits. 

Vitamin B12 is Important in Carbohydrate and Lipid Metabolism and Red Blood Cell Function

B12 is essential for growth, cellular reproduction, blood formation, neurological function, DNA and protein synthesis, among other things. B12 also aids in red blood cell production and metabolizing carbohydrates. Efficiently metabolizing carbohydrates and producing red blood cells that optimally carry oxygen to hardworking muscle and brain tissue boosts your overall energy and mental clarity.

Low-Dose Naltrexone

Low-dose naltrexone helps with weight loss by targeting insulin resistance, restoring growth hormone levels, modulating appetite, improving sleep patterns, and optimizing thyroid hormone.

  • Insulin resistance is when the body cannot effectively convert carbohydrates into energy.
  • Low-dose naltrexone may help restore growth hormone to physiological levels.
  • Low-dose naltrexone helps you resist cravings for unhealthy foods.
  • Sleep and weight loss are interconnected. Poor sleep causes fatigue, low energy, and lower motivation to exercise and resist unhealthy food choices. Weight gain can increase the risk of sleep apnea, which alters sleeping patterns.
  • Low-dose naltrexone may help optimize thyroid function.

How Does LDN Boost Work?

Oxytocin is Produced in the Brain and Acts on Brain Circuits that Promote Social Bonding

Oxytocin is produced in the hypothalamus in the brain. It has an effect on brain regions that regulate emotions (limbic system and amygdala). Oxytocin also acts on brain circuits that promote social bonding and affiliation with others.

Oxytocin is released from the pituitary gland in response to stress. Oxytocin is an anxiolytic. It decreases anxiety and the body’s response to stress.

Vitamin B12 Absorption is a Multi-Step Process

Vitamin B12 is an essential vitamin because it is obtained entirely through diet. Vitamin B12 is found in animal products and fortified foods in the diet, but it can also be taken as a supplement.

When bound to the food we eat, vitamin B12 is released from protein by hydrochloric acid and an enzyme called gastric protease. When vitamin B12 is added to food or taken as a supplement, it is already in a free form and does not need to be released. Once vitamin B12 is free, it combines with intrinsic factor in the stomach.

Intrinsic factor is a glycoprotein secreted by specialized cells lining the stomach called parietal cells. The combined intrinsic factor vitamin B12 is absorbed into the body in the ileum, which is the most distal part of the small intestine. Vitamin B12 then binds to transcobalamin, and the complex moves through the bloodstream. The complex is absorbed into cells. Approximately two years’ worth of vitamin B12 is stored in the liver.

Low-Dose Naltrexone is Used for Its Ability to Reduce Cravings, Reduce Pain, and Regulate the Immune System

Low-dose naltrexone seems to:

  • Act on opioid receptors to increase the release of beta-endorphins
  • Reduce pro-inflammatory cytokines and increase anti-inflammatory cytokines
  • Regulate opioid growth factor

Naltrexone is an opiate antagonist. It is used at a full dose to treat opioid addiction. Low-dose naltrexone helps regulate the immune system and is used to treat auto-immune disorders.
