Youthful has been centered on discovering remedies from the start
From the start, Jarred Youthful has all the time had his eyes peeled for potential remedies for fibromyalgia, ME/CFS – and now lengthy COVID. Youthful, the truth is, perhaps our most artistic researchers in the case of uncovering new remedies.
The one theme pervading Youthful’s therapy work has been making an attempt to tamp down neuroinflammation. Any therapy Youthful takes on has to have the ability to cross the blood-brain barrier and knock down that central nervous system irritation. Particularly, something that may tamp down the exercise of a receptor known as toll-like receptor 4 (TLR4), which prompts the microglia, is of particular curiosity to him.
Youthful, together with famous ache researcher John Mackay at Stanford, produced the primary LDN low-dose naltrexone research in fibromyalgia again in 2009. The research was notable, partly, as a result of the truth that LDN is compounded means pharmaceutical corporations have no real interest in it; i.e., it required a tutorial like Youthful or a health care provider to get its usefulness throughout in these ailments.
Youthful adopted up that research with three extra LDN research and is within the midst of a fourth. Over time, Youthful has additionally assessed the effectiveness of low-dose dextromethorphan (not efficient at 20 mg), recognized three botanicals (curcumin, stinging nettle, resveratrol) that may assist in Gulf Battle Sickness, and has, I imagine, acquired sufficient funding to discover a probably extra highly effective type of LDN known as a dextro-naltrexone trial.
He additionally has a psilocybin fibromyalgia trial below approach.
The Nalmefene Mission
Discuss engaged on the innovative. Youthful’s newest enterprise – to get funding to evaluate a drug known as nalmefene- may find yourself being one of the best of all of them. Youthful talked about this new challenge in a current video.
Low-dose nalmefene, it seems, does one thing much like LDN however extra successfully. LDN’s effectiveness is hampered by the shortcoming to take it in giant doses – however not so with low-dose nalmafine. Nalmefene lasts longer within the physique (8-10 hour half-life—so that you want much less), has a better bioavailability (40-50%—so once more you want much less), doesn’t have an effect on the liver (LDN can), binds to extra opioid receptors extra successfully, and perhaps 4xs higher at blocking these nastyTLR4 receptors that activate the microglia. Since Youthful believes the microglial cells in these ailments have develop into spectacularly hypersensitive blocking the TLR4 receptors that flip these cells on might be an enormous boon.
THE GIST
- Many times, Jarred Youthful has seemed far and large for remedies for ME/CFS, fibromyalgia (FM, and Gulf Battle Sickness. His aim, all the time, is to seek out medicine that may tamp down the neuroinflammation he’s present in these sicknesses.
- He’s assessed dextromethorphan, uncovered botanicals which will assist in Gulf Battle Sickness, found a extra highly effective type of LDN that (I imagine) he’s presently testing, and has a psilocybin fibromyalgia trial underway.
- His best influence, although, could come from a drug known as nalmefene, which he’s presently making an attempt to get funding for. Low-dose nalmefene does one thing much like LDN however could also be far more efficient; it has elevated bioavailability, hits extra factors within the mind, lasts longer within the physique, and seems to be MUCH simpler at turning down the receptors that flip the microglial cells within the mind.
- Youthful famous that solely full-dose nalmefene is obtainable within the US and elsewhere. He warned that the present dose of nalmefene supplied is so excessive that it’s going to most likely block your endogenous opioid ache system and provide you with malaise and emotions of lowness (each of which we have already got sufficient of!). He advisable ready till the trial outcomes – which can try to seek out the right dose – are in.
- An increasing number of therapy choices are showing. Current prospects embody monoclonal antibodies, checkpoint inhibitors, baricitinib, new antivirals (ensitrelvir), a number of antivirals, nicotine patches, and stellate ganglion blockades. There’s the capnography machine Dr. Natelson just lately discovered that sufferers can use to enhance CO2 ranges and relieve fatigue, and the current profitable inspiratory trial which offers a simple approach to enhance respiration and, probably, oxygenation.
- Most of those usually are not game-changers, and we’re nonetheless not seeing curiosity from the massive pharmaceutical corporations or giant medical trials—besides from the RECOVER Initiative—however we’re seeing extra prospects pop up.
- An fascinating one confirmed up in a case report that reported {that a} treatment-resistant lady with osteoporosis responded terribly effectively to a mix of low-dose naltrexone and rapamycin. Given the elevated charge of osteoporosis present in fibromyalgia and the robust chance that it’s elevated in ME/CFS as effectively (given the shortage of train doable), a simple approach to enhance bone density could be an enormous deal, certainly.
- On the lengthy COVID low-dose naltrexone entrance, a number of methodologically challenged research recommend that LDN could also be useful in lengthy COVID, and a extra rigorous one is underway.
Full-dose nalmefene is used equally to full-dose naltrexone. It’s out there within the US as an intranasal spray (Opvee) and an auto-injector (Zurnai) for emergency therapy of opioid overdose however will not be out there within the oral model Youthful desires to make use of. It’s additionally out there within the European Union and about 39 nations.
Whereas low dose nalmefene reveals actual risk, Youthful warned that the present dose nalmefene is obtainable at is so excessive that it’s going to most likely block your endogenous opioid ache system – and produce malaise and emotions of lowness. He advisable that sufferers look ahead to the outcomes of his trial.
Ought to he get funding, Youthful will deal with figuring out one of the best dose for situations like ME/CFS, FM, and lengthy COVID-19 and clear the best way for a bigger, placebo-controlled trial.
Remedy Prospects Maintain Displaying Up


Remedy prospects preserve exhibiting up.
Youthful’s new challenge highlights an essential issue—how increasingly new prospects for therapy are showing. Sure, they’re exhibiting up in a confusingly haphazard approach, however if you happen to take the time to look, increasingly therapy choices are showing.
Current prospects embody monoclonal antibodies, checkpoint inhibitors, baricitinib, new antivirals (ensitrelvir), a number of antivirals, nicotine patches, and stellate ganglion blockades, to call just a few.
Take stellate ganglion blockades – they had been used for 50 years earlier than somebody determined to attempt them in ME/CFS/FM and lengthy COVID. Take the capnography machine Dr. Natelson just lately discovered that sufferers can use to enhance CO2 ranges and relieve fatigue. Take the current profitable inspiratory trial, which offers a simple approach to enhance respiration and, probably, oxygenation. Take an oldie – vagus nerve stimulation – which is about to get a 50-person trial in individuals with lengthy COVID/ME/CFS (weblog developing).
It’s true that pharmaceutical corporations are nonetheless not embracing long-term COVID or ME/CF and that we nonetheless don’t have the massive medical trials that might flip issues the wrong way up in a single day. With out them, we’re nonetheless nibbling away at these ailments, however there are numerous extra nibbles now, and new prospects preserve exhibiting up.
A current case research demonstrates how little we will predict will occur over the following few years. Who, in spite of everything, may have predicted that LDN + rapamycin may assist with osteoporosis?
Low Dose Naltrexone (LDN) Plus Rapamycin Dramatically Improves Bone Density in Remedy Resistant Girl with Osteoporesis
We predict by way of LDN in fibromyalgia, ME/CFS, and lengthy COVID, however LDN is being studied in lots of ailments, together with vulvodynia, a number of sclerosis, Crohn’s illness, advanced regional ache syndrome, and fairly just a few rheumatological and autoimmune ailments.
With extra eyes than ever testing this intriguing drug maybe it’s not too shocking to see new prospects present up. The most recent, although, may have particular significance for ladies with ME/CFS, FM, and/or lengthy COVID if it pans out.
A just lately revealed case report, “Sudden Improve in Bone Mineral Density With Rapamycin and Low-Dose Naltrexone: A Case Report of a 52-12 months-Outdated Girl With Osteopenia,” means that LDN plus rapamycin could safely enhance bone mineral density in ladies for whom different remedies have failed.
Given the discovering of elevated charges of osteoporosis in fibromyalgia and the shortcoming of many individuals with ME/CFS to have interaction in even near regular quantities of train – an LDN/rapamycin increase in bone density – if it occurred in these situations as effectively, could be an actual boon.
Regardless of the identified – and probably devastating – dangers of hip and vertebral fractures as we age, many individuals, as they become old, nonetheless don’t get bone density assessments.
Numerous therapies – from medicine to train to vitamin – can improve bone density on common from 2-10% over a number of years in some individuals, however many individuals don’t reply; one drug is incompatible with fibromyalgia, and others can have important negative effects.
The Geroprotectors Present Up
Enter low-dose naltrexone and rapamycin—two medicine that the authors of the current case research known as “geroprotectors.” The case report involved a 52-year-old lady with osteoporosis who, regardless of making an attempt a number of interventions (hormone substitute remedy, a Mirena intrauterine gadget (IUD), weight-bearing cardiovascular train and resistance coaching, vitamin D3 supplementation, and excessive dietary calcium consumption), failed to enhance her bone density ranges.
In 2022, she enrolled in a double-blinded, placebo-controlled, 12-month low-dose rapamycin longevity trial, elevated her vitamin Okay ranges (which improve calcium binding to the bone), and a yr later started taking compounded LDN (beginning at 1.5 and progressing to 4.5mg). In November 2023, she additionally started oral progesterone supplementation (100 mg/nightly).
A DXA scan in 2024 revealed an astounding 15.9% improve in her lumbar bone density. (Her cervical bone density went up by about 4%). The authors wrote:
“These findings signify an surprising and substantial enchancment within the affected person’s bone well being, which was notably notable given the standard challenges in reaching important BMD will increase in sufferers with osteopenia, particularly post-menopausal ladies.”
Whereas the consequences of her dietary supplementation and continued train routine could have helped, the authors centered on rapamycin and LDN. They famous that the mTOR pathway that rapamycin impacts “performs an important function in bone transforming.” and believed LDN’s capacity to fight the “low-level, sterile irritation that could be a driver of bone resorption and degeneration” improved her bone well being.
Extra LDN Lengthy COVID Information
A methodologically robust LDN Lengthy COVID research has not but been revealed, however a retrospective Canadian research discovered that LDN was related to “fewer variety of signs, improved medical signs (fatigue, post-exertional malaise, unrefreshing sleep, and irregular sleep sample), and higher purposeful standing.” One other research discovered enchancment in restoration, limitations in actions of every day residing, power ranges, ache ranges, ranges of focus, and sleep disturbance.
An intriguing pilot research discovered that combining LDN and NAD+ produced a pleasant bounce in SF-36 scores and a major drop in fatigue scores in roughly half of the group labeled as responders.
The LDN dose climbed from 1mg for 4 days, 2 mg for the following 4 days, and the complete 4.5 mg dose taken within the night after that. 4 hundred mg/ml iontophoresis patches (IontoPATCH™️ STAT, ST. Paul, MN; supplied by Pharmacy Options, Ann Arbor, MI or Belmar Pharmacy, Golden, CO) using electrodes had been used. The patches (400 mg/mL NAD + resolution) had been worn for 4-6 hours as soon as per week.
A extra sturdy placebo-controlled, blinded LDN research (n=160) is underway in British Columbia. The research will begin with 1 mg and work as much as 4.5 mg (or no matter dose is tolerated).
Advances are being made—not on the tempo anybody would need—however they’re being steadily made. Now, nevertheless, a wild card has proven up. What the Trump administration decides to do with the Nationwide Institutes of Well being, the FDA, and probably the Social Safety Administration within the U.S. has the potential to profoundly influence individuals with lengthy COVID, ME/CFS, fibromyalgia, and dysautonomia. The following weblog critiques the place we’re at at this level.
