LDN – Could it be a “magic pill”?

LDN is a little known, life changing & very affordable medication with more and more success stories in the integrative and Functional Medicine world. It may just be the ‘magic’ pill many with chronic and Autoimmune conditions, difficulty losing weight and parents of Agitated Autistic children have long searched and prayed for.

LDN is an abbreviation for “Low Dose Naltrexone”.
You may know its (full dose) brother Naltrexone as the ‘anti-overdose’ drug used for reversing accidental overdose with opiates such as morphine, heroine, oxycontin etc.   Full dose Naltrexone is typically administered in doses up to 50mg, however about 20 years ago it was found that in very low doses (1.5 -4.5mg), it has profound effects on modulating the immune system and reducing chronic, miserable and deteriorating conditions.

Bear with this moment of science class…

LDN boosts the levels of a natural occurring chemical in our body called endorphins.
Endorphins got their name because they are “Endogenous (made in the body) Morphines” and totally different than the synthetic opiods (such as those mentioned above).

Most chronic conditions are a “too much or too little” cellular behavior.  Endorphins known as Opiod Growth Factors (OGF) are produced naturally in our body and bind to every cell in our body through an Opoid Growth Factor “receptor” or OGFR (think of this action like Velcro).  This Velcro action helps to control cellular growth (not too much, not too little).  For this binding action to work properly we must appropriately produce OGF and then it must bind to the OGFR (the ‘Velcro’).

Naltrexone is an OGFR blocker.
Have you ever had the experience when a toddler’s Velcro sneaker fails to fasten because the Velcro no longer ‘sticks’.  As it always does so well, the body’s response to this lack of OGF binding is to compensate and rebound by supercharging the signal and pushes more and more OGFR and more and more OGF.  The cells make more OGFR (more sticky Velcro) to try to get the higher amounts of OGF in as well as increasing the sensitivity to the OGF (now the Velcro is longer, thicker and stickier).

To help visualize this, the picture to the right shows the a cell covered in pink receptors (OGFR- the Velcro).  The yellow and green represent the OGF binding to the receptors. With Naltrexone (and LDN), this cell would be covered with many more pink, green and yellow molecules. Any dose of Naltrexone will produce this increase in receptors and growth factors. For any of this to occur, the body must first metabolize the medication; however, the higher the dose, the longer it takes to occur and experience the benefits.

Low dose Naltrexone works exactly the same way, however the ‘blocking’ of the OGFR lasts only a couple of hours as the lower dose is quickly metabolized and excreted from the body. In this case, it’s a good thing as the short term blockade allows for a higher level of natural opiod (feel good) hormones for the following 18-20 hours.

LDN also prevents the immune system from working overtime.
Our bodies have an amazing ability to overcompensate for balance. By increasing the number of pink (OGFR), green and yellow (OGF), the immune system now works at a more appropriate rate (not too much as in AutoImmunity and not too little as in poor immune system not fighting appropriately).
The body working ‘overtime’ (or attacking what it shouldn’t) is something many suffering from Autoimmunity know too well as the culprit for many miserable and life altering symptoms. As explained above; when taken at bedtime, LDN attaches to opioid receptors in the brain and in all types of immune cells, temporarily blocking endorphins’ ability to attach to the immune cells.
OGF & OGFR are joined by the immune system guys – specificallty the T-regulatory cells (aka T-regs).  Think about T-regs as the police in our body. They are there to keep peace and help out when needed, but also enforce the law to ensure balance in our community. T-regs keep the immune system in balance in our body by turning inflammation on and off, depending on the body’s needs.  They also prevent the immune system from getting stuck or “freaking out” in patients with overactive immune systems, such as those with allergies or asthma or Autoimmune conditions (ie: attacking things it shouldn’t such as the thyroid in Hashimoto’s Hypothyroid or myelin sheath on the brain in Multiple Sclerosis).

 

What is the connection between the OGF, OGFR and the Immune system?
People with Autoimmune conditions often have low levels of the OGF and OGFR. White blood cells (our ‘fighting’ immune cells) drive the immune response and they have receptors for these opioids. LDN also blocks a receptor on white blood cells called Microglia which is responsible for inflammation in the body. If the Microglia are constantly on alert, we have symptoms of inflammation such as pain, fatigue, insomnia, mood disorders and cognitive disorders (such as brain fog, dementia, etc).  LDN blocks the receptors on the Microglia cells and in turn reducing Central Nervous System infllammation. This reduced inflammation has been shown to reduce ESR (erythrocyte sedimentation rate), which is an inflammatory marker that’s elevated in many AutoImmune conditions.

Ok – enough science! What does this mean and who might benefit from LDN?

Who might benefit from LDN? 

Where can I get LDN? 
LDN is not available from most traditional medical providers or at chain pharmacies because it is a Compounded medication (ie: made in a compounding pharmacy). Most Functional Medicine providers (like 4 Better Health) are prescribing LDN when appropriate for their patients. We do not recommend you purchase these from overseas pharmacies.  There are no safety standards and not knowing what you are really getting and should you be not getting LDN, health issues could increase dramatically.

 

What is the dose?
The suggested dose is 1.5–4.5 mg per day in a capsule or liquid, taken orally at bedtime. The medication should not be in a ‘slow release’ formula. As mentioned above, we want the fast metabolism for the best response.  Some people have found that the best formula are those made without Calcium Carbonate (a filler for many pharmacies).

Is LDN addictive? LDN does not have any known abuse potential. It’s not an addictive medication.

 

Are there Contraindications?  
LDN blocks the Opiod receptor = Narcotics will not be effective. Anyone who needs a Narcotic medication (whether it be for an acute reason such as injury or surgery or those who are using them chronically) would not be a candidate as their narcotics will not offer the pain relief they require. LDN may interfere with the efficacy of immunosuppression medications (such as those who’ve had an organ transplant).
LDN does not effect NSAIDs (ibuprofen, Aleve, Naproxen, etc) or Tylenol & acetaminophen.
LDN is well tolerated. The biggest side effect is sleep disturbance and vivid dreams at first, but these typically go away after time. To avoid this, start with a dose of 1.5 mg and build up slowly over two months. Some patients have complained of nausea.

“Prior to working with Lisa I’d have to be home-bound one day every other weekend in order to deal with my problem. Now that I don’t need to do that anymore I’m back to hiking/mountaineering, kayaking, bike riding, snow-shoeing, being with friends, and spending time in the White Mountains. I am soo thankful for all 4 Better Health has done for me. You had a MAJOR hand in getting me back into this kind of shape [and I’m looking forward to getting even stronger and more fit]. I feel in command of my life again and I am enjoying doing all the outdoorsy, active things I love to do! What a gift you have given me!”

John Curcio

jenweightloss“My weight has always been a fight. I was having trouble sleeping  and walking upstairs because of pain in my hip and knee. I have tried a million diets but in the end I never felt in control of what I ate. When I made the decision to do the cleanse/detox I had my reservations. But it changed me. What I want
to eat and what my body craves. I feel better than I have in years. I am  sleeping better than ever and taking the stairs every chance I get. In 6 months I’ve gone from 265# to 180#. It’s all planning and consistency!”

Jenn

I was exhausted and in pain- aching from my neck to toes and waking up 4 or 5 times a night. My doctors told me it was just old age. Within a week of taking a few supplements and small changes to my diet recommended by 4 Better Health; my pain was drastically reduced and I began sleeping so much better. I am doing much more than I had been able to do in a very long time, my spirits are better, my outlook is better and I couldn’t ask for anything more. I would recommend this practice to everyone.
