Geranylgeraniol Explained: Benefits, Side Effects & Science Behind It

GG’s Role & Versatility 

GG is ubiquitous. The yellow, red, orange, or maroon hues of carotenoids found in a plant's fruits, seeds, roots, or leaves directly indicate the presence of GG. It means if you see any of these colors in parts of plants, know that it’s because of GG.  

Similarly, when you see the heme color (red) in organs and the vasculature of animals or humans, this indicates that GG is present. It implies GG is present everywhere.  

Geranylgeraniol plays a critical role in producing the pigments plants need for photosynthesis. It acts as a key ingredient in: 

Chlorophyll Production: The green pigment that plants need to capture sunlight. 

Carotenoid Production: GG is also converted into carotenoids, such as carotene and lutein, which give leaves their color and protect them from damage. 

GG can also be transformed into other compounds such as phytol, lycopene, and more carotenoids. When converted into phytol, it helps produce vitamin E (tocopherol) and vitamin K1. Tocotrienol, the potent form of vitamin E, is made directly from GG.  

GG geranylgeraniol also plays a crucial role in animals. In humans, GG and other isoprenoids are synthesized in the mevalonate pathway. Important compounds like cholesterol, vitamin D, vitamin K2, sex hormones (testosterone and progesterone), ubiquinone (CoQ10), and proteins are also produced through this same pathway. Our body primarily uses GG to synthesize these crucial compounds.   

Why Do Geranylgeraniol Levels Decline? 

The mevalonate pathway naturally slows down over time. By now, you know that the path is responsible for producing essential compounds, including cholesterol, CoQ10, Vitamin K2, and sex hormones.   

However, what you might not know is that with age, its ability to produce these compounds decreases due to reduced enzyme activity and a slowdown in metabolism, which impacts GG levels in the body.  

Besides, certain medications like statins (used for lowering cholesterol) and bisphosphonates (used to strengthen bones) inhibit the mevalonate pathway, thereby blocking GG production in the body. 

This decline in  GG levels may contribute to muscle loss, reduced energy, weaker bones, and hormonal imbalances as we get older. 

Geranylgeraniol Benefits for Health & Wellness 

Geranylgeraniol is more than just a building block in the body. It plays a crucial role in various biological processes. From supporting muscle and bone health to enhancing hormone production, GG offers a range of benefits that contribute to overall well-being. Here’s how this powerful endogenous compound can impact your health. 

Vitamin K is an essential nutrient known for its role in blood clotting. However, it is also essential for bone health. The K2 form of vitamin K, known as menaquinone, is especially important as it acts as a calcium regulator. It means it helps direct calcium to where it’s needed, like bones and teeth, while preventing it from building up in soft tissues like kidneys, blood vessels, gall bladder, and joints. It helps reduce the risk of kidney stones, arterial calcification, and arthritis.  

Research done in 1960 discovered that geranylgeraniol is essential for the production of Vitamin K2 (MK-4). Without enough GG, the body cannot efficiently convert Vitamin K1 into MK-4, which is necessary for proper distribution of calcium. 

Statins also lower Vitamin K2 levels, which is why those taking statins have a higher chance of arterial calcification. However, studies have shown that supplementing with GG helps restore Vitamin K2 levels, supporting proper calcium distribution and bone health. 

GG is a building block for protein synthesis and helps maintain the skeletal structure of cells. With age, our body loses muscle strength and mass. This impacts our quality of life and ability to stay active and independent. Gradual loss of muscle mass, strength, and function is termed sarcopenia. 

Proteins are essential for muscle health. Research suggests that geranylgeraniol (GG) may help maintain muscle health by supporting protein production. GG also helps keep proteins attached to cell membranes, helping maintain muscle structure and function. 

 Geranylgeraniol supports nitric oxide production, which helps blood vessels relax and improve circulation. This benefits overall muscle health and performance. A study found that GG prevented statin-induced muscle weakness and fatigue, suggesting that it may help people taking statins maintain muscle health. 

Geranylgeraniol is a key building block for CoQ10 synthesis in the mevalonate pathway. By supporting natural CoQ10 production, GG plays a crucial role in maintaining cellular energy, heart function, and overall vitality, making it beneficial for aging individuals and those taking statins. 

CoQ10  is a vital compound that helps cells produce energy through the electron transport chain in mitochondria. As we age, CoQ10 levels naturally decline.  

Statins also unintentionally reduce CoQ10 levels in the body. This leads to impaired mitochondrial function, lower energy production, and increased muscle fatigue. This reduction is also linked to several age-related illnesses, including type II diabetes and cancer. 

Studies show that geranylgeraniol GG supplements restore CoQ10 production. It also helps reverse the negative effects of statins on mitochondria, improving energy generation. It is worth noting that GG supplementation works without interfering with the cholesterol-lowering benefits of statins. Research also suggests that GG is more effective than direct CoQ10 supplementation in counteracting statin-induced side effects. 

As men age, their testosterone levels decline naturally. Low testosterone levels can lead to infertility, sexual dysfunction, and an increased risk of chronic diseases.  

Testosterone is produced in the Leydig cells of the testicles and synthesized from cholesterol, which is a product of the mevalonate pathway. Geranylgeraniol (GG) plays a key role in testosterone production in men. GG stimulates the steroidogenesis pathway, increasing both testosterone and its precursor hormone, progesterone. 

The steroidogenesis pathway is the biological process by which the body produces steroid hormones, including testosterone, estrogen, progesterone, cortisol, and aldosterone. These hormones are derived from cholesterol and are essential for various functions like metabolism, immune response, reproduction, and stress management. 

Research suggests that GG supplements can significantly boost testosterone levels. GG is also closely linked to Vitamin K2 (MK-4), and together, they help regulate hormone production. Vitamin K2 supports testosterone production by activating enzymes in Leydig cells, reducing oxidative stress, and enhancing mitochondrial function crucial for hormone synthesis. 

An 8-week randomized, placebo-controlled trial suggests that geranylgeraniol supplementation may benefit men with low testosterone levels. The study involved 66 healthy adults aged 30-49. Participants received 150 mg of annatto-derived GG-Gold supplement daily for the first four weeks, followed by 300 mg daily (150 mg twice per day) for the subsequent four weeks.  

The study results showed an increase in total (7.5%), free (15%), and bioavailable (14.8%) testosterone in those using GG, while the placebo group experienced declines. The study confirmed GG's safety, suggesting it as a natural option for supporting testosterone levels.

Statins: Statins are widely known for their cholesterol-lowering ability. However, statins can block an essential pathway (the mevalonate pathway) that produces not just cholesterol but also other essential compounds such as CoQ10, vitamin K2, and geranylgeraniol. The disruption can lead to several side effects, like muscle pain, weakness, and mitochondrial damage, affecting the energy production in cells. Research suggests that it is the depletion of GG that causes statin-induced muscle damage, with CoQ10 reduction playing a lesser role. Loss of GG triggers muscle atrophy by activating a gene called atrogin-1, which causes muscles to break down.   

Statins also unintentionally disrupt the protein prenylation process, in which GG plays a key role. Studies indicate that GG supplementation can reverse the damage caused by statins by restoring cell function and viability. 

While CoQ10 shows mixed results in reducing muscle-related statin side effects, GG has demonstrated positive results in protecting mitochondrial function and supporting cellular processes vital for muscle health. 

What is Protein Prenylation? 

Protein prenylation is a process that helps proteins attach to cell membranes so they can function properly. It is like adding a small "anchor" to proteins, allowing them to stay in place and do their job inside cells. 

This process is essential for many important functions, including cell growth, communication, and energy production. Geranylgeraniol (GG) plays a key role in this process by providing the necessary building blocks for these protein "anchors." 

Bisphosphonate: These drugs are commonly used to treat osteoporosis. Along with the treatment, these medications can have serious side effects. Particularly, the nitrogen-containing bisphosphonates (NBPs) can interfere with the body's ability to produce GG. It does so by blocking a key enzyme, farnesyl pyrophosphate synthase, in the mevalonate pathway.  

A major side effect associated with NBPs is osteonecrosis of the jaw (ONJ). This painful condition occurs when the jawbone begins to weaken and die gradually. Unfortunately, no approved treatment exists for ONJ. 

Research indicates that geranylgeraniol supplements may help prevent and reverse jaw osteonecrosis. GG has the potential to improve blood vessel formation (angiogenesis), which is crucial for healing and bone health. Studies suggest that when GG is given alongside NBPs, it may protect various cells in the jaw, including bone-forming cells, gum cells, and blood vessel cells. It helps keep these cells alive and improves their ability to grow and repair tissues.
