If you've never heard of Low Dose Naltrexone (LDN), prepare to meet one of the most versatile and promising therapies in both functional and integrative medicine. Originally developed in the 1980s for opioid and alcohol addiction, naltrexone at its full dose (typically 50mg) acts as an opioid receptor blocker. But when dosed much lower–usually between 0.5mg and 4.5mg–this compound takes on an entirely different personality. That's where LDN shines, and that's where compounding pharmacies like ours come in.
What Is Low Dose Naltrexone (LDN)?
LDN works by temporarily blocking opioid receptors for a short period. During this time, the body compensates by increasing its own production of endorphins–our natural feel-good chemicals. This boost can help regulate the immune system, reduce inflammation, and improve mood, pain tolerance, and overall resilience. In essence, LDN nudges the body toward balance, gently and naturally.
Why Is LDN Compounded?
LDN is not commercially available in low doses, which means compounding pharmacies are the only way patients can access it. At Apothecary & Co, we compound capsules and liquid forms of LDN in a range of dosages to meet your provider's recommendations.
Many patients need alcohol-free, dye-free, or filler-free versions of LDN due to sensitivities or dietary restrictions. That's where personalized compounding makes all the difference.
Functional Uses of LDN
LDN has been used off-label in a wide range of chronic and autoimmune conditions. Here are some of the most exciting areas of application:
Autoimmune Conditions
LDN has immune-modulating effects, making it especially helpful for autoimmune conditions like:
- Rheumatoid Arthritis
- Lupus
- Multiple Sclerosis
- Inflammatory Bowel Diseases (Crohn's and Ulcerative Colitis)
- Psoriasis
Patients often report fewer flares, reduced pain, and improved energy levels with consistent use.
Neurological & Mental Health Conditions
LDN's effects on inflammation and endorphins make it helpful for:
- Fibromyalgia
- Chronic Fatigue Syndrome
- Anxiety and Depression
- PTSD
- Migraines
- Parkinson's Disease
Its gentle nature and low risk of side effects make it a great addition to holistic care plans when other medications haven't worked–or caused too many side effects.
LDN and Thyroid Health
One of the most talked-about uses of LDN in functional medicine is for Hashimoto's Thyroiditis, an autoimmune condition that attacks the thyroid gland.
In Hashimoto's, the immune system becomes confused and begins attacking healthy thyroid tissue. LDN may help calm this immune overreaction, support the body's natural endorphin levels (which are often low in autoimmune disease), and reduce inflammation-all of which can help people with Hashimoto's feel better overall. Many patients report:
- Less brain fog
- Improved energy
- Reduced joint pain
- More stable thyroid antibodies over time
While LDN is not a replacement for thyroid hormone replacement therapy, it can be a powerful complementary therapy when added under the guidance of a healthcare provider.
What to Expect with LDN
LDN is typically started at a low dose and gradually increased. A common starting point is 0.5mg to 1.5mg, titrating up slowly to the typical target dose of 3mg-4.5mg daily, depending on the patient's condition and tolerance.
It's generally well tolerated, though some people may experience vivid dreams or initial sleep disturbances-especially if started too quickly. That's why we often say, “low and slow wins the race” with LDN.
Improvement can be gradual, often taking several weeks to a few months to fully notice the benefits.
