If you happen to’ve been following my work, you might have lately learn my article on geranylgeraniol (GG) and its remarkable ability to reverse statin-induced muscle pain the place CoQ10 has failed. Immediately, I need to share one other essential software of this identical compound — one that might assist stop a devastating situation that has left many sufferers with useless jaw bone and no efficient therapy choices. The situation known as bisphosphonate-related osteonecrosis of the jaw, or BRONJ for brief. And the answer, as soon as once more, is GG.
What Are Bisphosphonates and Who Takes Them?
Bisphosphonates are a category of medication prescribed primarily for osteoporosis and for stopping bone issues in most cancers sufferers. Chances are you’ll know them by model names like Fosamax (alendronate), Boniva (ibandronate), Actonel (risedronate), and Zometa or Reclast (zoledronic acid).
These medicine work by inhibiting osteoclasts, the cells chargeable for breaking down outdated bone. By suppressing bone resorption, bisphosphonates can improve bone density and cut back fracture threat. For most cancers sufferers with bone metastases, they may also help stop skeletal issues.
Hundreds of thousands of individuals take these medicines. Actually, bisphosphonates are among the many mostly prescription drugs for postmenopausal ladies with osteoporosis. However like all medicine, they arrive with dangers, and one of the vital severe is osteonecrosis of the jaw.
The Horror of Jaw Bone Demise
Osteonecrosis actually means “bone dying.” When it happens within the jaw, the bone tissue dies and turns into uncovered by way of the gums, failing to heal. Sufferers develop painful, uncovered bone of their mouth that may change into contaminated, result in tooth loss, and in extreme instances require surgical elimination of parts of the jaw.
The situation is recognized when a affected person has uncovered jaw bone that does not heal inside eight weeks, has a historical past of taking bisphosphonates or related medicines, and has no historical past of radiation remedy to the jaw space.
What makes BRONJ significantly insidious is that there’s at present no dependable remedy. As soon as the jaw bone dies, therapy choices are restricted to managing signs, controlling an infection, and in some instances surgical debridement or elimination of useless bone. Prevention is the one really efficient technique.
The situation usually develops after dental procedures — tooth extractions, implant placement, or different invasive dental work. Because of this dentists now routinely ask sufferers about bisphosphonate use earlier than performing procedures, and why some advocate “drug holidays” earlier than dental surgical procedure.
However what if there was a method to shield the jaw bone whereas nonetheless taking these medicines? What if the identical compound that reverses statin muscle harm may additionally stop bisphosphonate jaw harm?
Similar Mechanism, Similar Resolution
Here is the important thing perception that connects these two seemingly totally different circumstances: bisphosphonates and statins work by way of the identical biochemical pathway.
Each drug lessons inhibit enzymes within the mevalonate pathway. Statins block HMG-CoA reductase on the high of the pathway. Bisphosphonates — particularly the nitrogen-containing bisphosphonates like zoledronic acid — block farnesyl pyrophosphate synthase additional down the pathway.
The tip outcome is identical: depletion of geranylgeranyl pyrophosphate (GGPP), the activated type of GG. And when GGPP is depleted, the method of protein prenylation — important for regular cell operate — is impaired.
In muscle cells, this manifests because the muscle ache, weak point, and fatigue that statin sufferers expertise. Within the jaw bone, the place there’s fixed transforming exercise and publicity to oral micro organism, this manifests as impaired therapeutic and eventual bone dying.
A 2022 evaluation printed in Frontiers in Pharmacology1 defined the connection clearly: “Nitrogen-containing bisphosphonates suppress osteoclastic resorption by inhibiting farnesyl pyrophosphate synthase within the mevalonate pathway, resulting in deficiency of the substrate for GTPase prenylation. The bone transforming course of is uncoupled, subsequently impairing bone therapeutic and inflicting ONJ.”
The evaluation went on to notice that “focused administration of geranylgeraniol (GGOH) represents a promising strategy to mitigate BRONJ as a result of GGOH is a substrate for GTPase prenylation.”
GG Reverses Bisphosphonate Injury to Jaw Cells
A number of research have demonstrated that GG can reverse the mobile harm brought on by bisphosphonates in precisely the cell varieties which are essential for jaw bone well being.
A 2011 research printed in Oral Oncology2 was among the many first to indicate that GG may reverse the adverse organic results of nitrogen-containing bisphosphonates on endothelial cells (which type blood vessels), fibroblasts (which type connective tissue), and osteogenic cells (which type bone). The researchers discovered that GG restored the viability and migration capability of those cells after bisphosphonate therapy.
A 2021 research printed in Frontiers in Cell and Developmental Biology3 investigated the particular mechanism by which bisphosphonates trigger jaw bone issues. The researchers discovered that zoledronic acid (a potent bisphosphonate) each promoted the dying of osteocytes (bone cells) and inhibited the flexibility of macrophages to clear useless cells — a course of referred to as efferocytosis that is important for correct therapeutic.
Critically, the research discovered that “complement with geranylgeraniol (GGOH), a substrate analog for geranylgeranylation of Rac1, may restore Rac1 homeostasis and rescue macrophage efferocytosis.” Rac1 (together with a intently associated protein referred to as Rac2) acts like an on-off swap that helps immune cells transfer, connect to broken tissue, and clear away useless cells so therapeutic can happen.
These proteins want to connect to cell membranes to work correctly, and so they want geranylgeraniol to do this. When bisphosphonates block this course of, Rac signaling breaks down and immune cells can not clear up broken tissue. In different phrases, GG restored the conventional therapeutic course of that bisphosphonates had disrupted.
A 2020 research4 examined the consequences of zoledronic acid and GG on angiogenic (blood vessel-forming) gene expression in human osteoclasts. The researchers discovered that bisphosphonate therapy altered the expression of a number of genes concerned in blood vessel formation — a key consider bone therapeutic. Addition of GG resulted in discount of those altered gene expressions, suggesting it may assist normalize the angiogenic response.
GG in Bone Cement Promotes Therapeutic
Maybe most fun is a 2024 research printed within the Journal of Oral Biology and Craniofacial Analysis5 that examined GG in an precise mannequin of medication-related osteonecrosis of the jaw.
Researchers integrated GG into bone cement pellets and examined their results each in cell tradition and in animals. They discovered that GG launched from the bone cement elevated osteoclast survival and metabolic exercise and promoted resorption of calcified substrate — basically restoring regular bone transforming operate.
Within the animal mannequin, launched GG “restricted the consequences of the bisphosphonate and promoted therapeutic.” The researchers famous that “GGOH from the infused cement service stabilizes bone construction and restores the flexibility of osteoclasts to rework.”
The conclusion was encouraging: “These preliminary findings level to GGOH in a bone cement service as a helpful therapeutic strategy to stop or mitigate the pathogenesis of MRONJ.”
Whereas this particular supply methodology (bone cement) is a scientific software that may have to be carried out by a dental surgeon, the underlying precept is obvious: GG can reverse bisphosphonate-induced harm to the cells chargeable for jaw bone well being and therapeutic.
The Connection to Statin Myopathy
If you happen to learn my earlier article on GG for statin-induced muscle issues, you will acknowledge the sample. Each statins and bisphosphonates:
1. Inhibit the mevalonate pathway
2. Deplete geranylgeranyl pyrophosphate (GGPP)
3. Impair protein prenylation
4. Trigger tissue harm (muscle or bone) by way of this mechanism
5. Might be counteracted by GG supplementation
This is not a coincidence — it is biochemistry. These medicine work by way of the identical basic mechanism, which is why they trigger associated issues and why the identical answer addresses each.
The analysis on GG for statin myopathy is extra superior, with a number of in vivo research and meta-analyses confirming that CoQ10 would not work whereas GG does. The analysis on GG for BRONJ continues to be growing, with most research being in vitro (cell tradition) or in animal fashions. However the consistency of the findings throughout each circumstances strongly helps the underlying mechanism.
Who Ought to Think about GG Supplementation?
Primarily based on the obtainable proof, GG supplementation makes specific sense for:
• Individuals taking bisphosphonates for osteoporosis — If you happen to’re on Fosamax, Boniva, Actonel, or related medicines, GG supplementation might assist shield your jaw bone, particularly in the event you want dental procedures.
• Most cancers sufferers receiving bisphosphonate remedy — Excessive-dose intravenous bisphosphonates like Zometa carry a better threat of BRONJ. Supplementation with GG may present protecting advantages.
• Anybody planning dental work whereas on bisphosphonates — Tooth extractions and implant placement are identified triggers for BRONJ. GG supplementation earlier than, throughout, and after dental procedures might assist assist regular therapeutic.
• Individuals taking statins who additionally take bisphosphonates — Many older adults take each drug lessons. Each deplete GG by way of the identical pathway. The mixed depletion makes supplementation much more essential.
Sensible Suggestions
The sensible suggestions for GG supplementation within the context of bisphosphonate use are much like these for statin use:
• Dosing — 150 mg to 300 mg each day seems to be the vary utilized in analysis.
• Type — Trans-geranylgeraniol from annatto seeds (usually bought as “GG-Gold” or related branded varieties) has been essentially the most studied.
• Timing round dental procedures — If you happen to’re planning dental work, think about beginning GG supplementation a number of weeks earlier than the process and persevering with throughout therapeutic. Focus on this along with your dentist and doctor.
• Period — Not like some dietary supplements which are taken solely when symptomatic, GG supplementation could also be most precious as ongoing assist whereas taking bisphosphonates, on condition that these medicine can persist in bone tissue for years.
• Security — GG has demonstrated a wonderful security profile in analysis. It doesn’t seem to intrude with bisphosphonates’ bone-building results, much like the way it would not intrude with statins’ cholesterol-lowering results.
A Unified Method to Mevalonate Pathway Help
The story of geranylgeraniol can be a story about understanding biochemistry reasonably than simply treating signs. Once we acknowledge that each statins and bisphosphonates deplete the identical essential compound — and that this depletion causes issues in several tissues relying on which drug you are taking — we will undertake a unified strategy to safety.
• For statin customers — GG addresses the foundation explanation for muscle signs that CoQ10 could not remedy.
• For bisphosphonate customers — GG helps the jaw bone well being that these medicine compromise.
• For folks taking each — GG replenishes what each drug lessons deplete.
That is the sort of integrative considering that standard drugs usually misses. Quite than treating statin myopathy and bisphosphonate jaw necrosis as fully separate circumstances requiring separate options, we will acknowledge their frequent trigger and handle them collectively.
If you happen to’re taking both statins or bisphosphonates — or particularly in the event you’re taking each — GG deserves severe consideration as a part of your complement routine. The analysis is obvious, the mechanism is known, and the security profile is superb. Focus on it with a healthcare supplier conversant in integrative approaches, and take management of defending your muscular tissues and bones from pharmaceutical negative effects.
