In the realm of natural medicine, few substances captivate attention quite like Shilajit. This ancient remedy, long revered in Āyurveda for its myriad health benefits, has recently drawn the interest of the scientific community for its potential to enhance cognitive function and combat neurodegenerative diseases, including Alzheimer’s. This article delves into the profound relationship between Shilajit, its key component fulvic acid, and their promising roles in the prevention and treatment of Alzheimer's disease.
Understanding Tau Proteins and Their Significance in Alzheimer's Disease
To comprehend why Alzheimer’s disease happens, it’s essential to first understand tau proteins. These proteins are vital helpers in the brain, maintaining order by supporting the structure and transportation within brain cells. They function like railway tracks, guiding essential materials to their destinations within the brain. However, when tau proteins become tangled and clump together, they disrupt their usual functions. This disruption can impair brain cells, leading to issues such as memory loss and confusion—common symptoms of Alzheimer’s disease and Dementia.
Shilajit can be likened to a specialised cleaner, preventing these tau proteins from sticking together and forming harmful tangles. It even has the potential to break apart already-formed tangles. This is crucial because preventing or dissolving these clumps could help protect the brain and maintain its functionality for longer. While scientists are still exploring the exact mechanisms in real-life scenarios, the idea is that Shilajit plays a significant role in brain health by managing these tau proteins.
The Ancient Wisdom and Composition of Shilajit
Shilajit holds a revered status in Āyurveda, recognised as a "rasayana"—a classification denoting substances that promote longevity, rejuvenation, and overall well-being. Traditionally, it has been used for centuries to boost physical strength, enhance cognitive function, and prevent aging. Additionally, the Herbal Medicine Division of the Indian Defence Research and Development Organization has experimentally proven Shilajit to be an antistress, antianxiety, antiepileptic, and adaptogenic agent.
According to a peer-reviewed paper titled Shilajit: A Natural Phytocomplex with Potential Procognitive Activity, “Shilajit is composed mainly of humic substances, including fulvic acid, that account for around 60% to 80% of the total nutraceutical compound plus some oligoelements including selenium of antiaging properties”. This unique composition, rich in essential minerals and fulvic acid, endows Shilajit with potent antioxidant properties, making it a formidable defence against oxidative stress—a key factor in aging and cognitive decline.
Shilajit is also revered as a “yogavaha,” a term in Āyurveda which signifies an ‘enhancer of other medicines’. The organic components of Shilajit, particularly fulvic acid, play a critical role as carrier molecules, facilitating the transport of various minerals to their cellular targets. This optimises nutrient delivery to deep tissues at the cellular level while also aiding in the removal of deep-seated toxins. This attribute is particularly significant in the context of cognitive health, where nutrient absorption and cellular rejuvenation are vital for maintaining brain function and preventing neurodegenerative diseases. Beyond Alzheimer's disease, humic acid, another key component of Shilajit, has been proven to enhance the delivery of certain anti-epileptic drug treatments for similar reasons.
Shilajit and Alzheimer’s: The Role of Fulvic Acid
Alzheimer’s disease is one of the most prevalent neurodegenerative disorders, characterised by the abnormal accumulation of tau proteins in the brain. This buildup leads to the formation of tau fibrils, which disrupt neuronal function and eventually cause cognitive decline and memory loss. According to the UK Alzheimer’s Society, there are currently estimated to be 982,000 people living with dementia in the UK, a number projected to rise to 1.4 million by 2040. While pharmaceutical treatments exist to manage Alzheimer’s in its early and mid-stages, there is currently no cure for the disease. Nonetheless, the relationship between Shilajit, particularly its fulvic acid content, and Alzheimer’s is especially compelling.
A study entitled Fulvic Acid Inhibits Aggregation and Promotes Disassembly of Tau Fibrils Associated with Alzheimer’s Disease, co-authored by the Laboratory of Cellular and Molecular Neurosciences and the International Center for Biomedicine, highlights the potent effects of fulvic acid on tau proteins. The study demonstrates that “fulvic acid is a promising molecule able to inhibit and disassemble tau fibrils,” which are critical in the development and progression of Alzheimer’s disease. By preventing the formation of these harmful fibrils and even disassembling existing ones, fulvic acid helps protect neurons from the damage typically seen in Alzheimer’s patients.
Furthermore, the study explains how “fulvic acid inhibits heparin-induced tau aggregation in vitro” and promotes the disassembly of preformed tau fibrils. This dual action is crucial in slowing down or potentially reversing the early progression of Alzheimer’s, making fulvic acid a key natural compound in the fight against this debilitating disease. The ability of fulvic acid to reduce hydrophobic interactions in tau proteins, thereby diminishing their aggregation, offers new insights into developing natural treatments for Alzheimer’s.
Shilajit as a Yogavaha and Enhancing Existing Treatments
In Āyurveda, the term "yogavaha" refers to a substance that acts as a synergistic enhancer, amplifying the effects of other drugs or nutrients it is paired with. The word is derived from two Sanskrit words: "yoga," meaning union or combination, and "vaha," meaning carrier or vehicle. Shilajit, a powerful natural compound, is celebrated for its yogavaha properties. This unique characteristic allows Shilajit to work in harmony with other substances, enhancing their bioavailability and effectiveness.
According to research from the Herbal Medicine Division of the Indian Defence Research and Development Organization, "Shilajit contains active organic molecules such as fulvic acid along with minerals (in their ionic forms). The fulvic acid helps in the transportation of these minerals into cells for maintaining and restoring their electrical potency, which prevents their decay and death." This means that Shilajit not only delivers vital nutrients to your cells but also ensures they are utilised in the most efficient manner possible.
Additionally, in the aformentioned article entitled: Shilajit: A Natural Phytocomplex with Potential Procognitive Activity, the authors highlight that "Shilajit has been claimed in India to be used as yogavaha, that is, as a synergistic enhancer of other drugs. Organic components of Shilajit play a role in transporting different mineral substances to their cellular targets." This reinforces that Shilajit doesn’t just work alone; it enhances the performance of other therapeutic substances, making it a valuable addition to any health regimen.
Through its fulvic acid content, Shilajit has shown potential in slowing the progression of Alzheimer's disease and might even help in preventing its onset by combatting the harmful aggregation of tau proteins in the brain. However, as of 2024, while Shilajit offers promising natural benefits, it is not a standalone treatment for Alzheimer's. Other treatments and interventions have been studied more extensively and are currently more effective.
Some of the most prominent treatments for Alzheimer's include:
Cholinesterase Inhibitors: Drugs like Donepezil, Rivastigmine, and Galantamine work by increasing levels of acetylcholine, a neurotransmitter associated with memory and learning, which is often reduced in people with Alzheimer's.
NMDA Receptor Antagonists: Memantine regulates glutamate activity, another neurotransmitter that can contribute to brain cell damage when produced in excess.
Monoclonal Antibodies: Newer treatments like Aducanumab and Lecanemab target beta-amyloid plaques, another key pathological feature of Alzheimer's. These drugs aim to slow down the progression of the disease by reducing plaque buildup in the brain.
While Shilajit is not a replacement for these established treatments, it can certainly be used in conjunction with them to potentially enhance their effectiveness and provide a holistic approach to brain health. As a 'Yogavaha', rich in fulvic acid, Shilajit has the dual effect of combatting the irregular aggregation of tau proteins and boosting the efficiency of other anti-Alzheimer’s treatments.
Shilajit’s Broader Health Benefits and Future Applications
The benefits of Shilajit extend far beyond cognitive health. Its rich composition of minerals and fulvic acid contributes to various health improvements, from boosting immunity and enhancing metabolism to improving heart health and increasing physical endurance. The traditional use of Shilajit in Āyurveda as a remedy for a wide range of ailments, including digestive disorders, respiratory issues, and even chronic fatigue, underscores its versatility as a natural medicine.
For example, a 2020 study conducted at the Indiana University School of Medicine delved into the potential skin health benefits of Shilajit. The findings highlighted that Shilajit and its active compounds may offer various pharmacological advantages, such as adaptogenic, antioxidant, anti-inflammatory, and neurological effects. These properties contribute to healthier, smoother, and more youthful-looking skin, with Shilajit positively influencing skin microperfusion.
Another example of Shilajit’s multi-faceted benefits is that Shilajit has been shown to support immune system health and may enhance the effectiveness of conventional HIV treatments. The study revealed that when Shilajit was administered to HIV patients, it not only boosted their immune cell counts (CD4 and CD8 cells, which are crucial for immune function) but also led to noticeable improvements in their symptoms. This suggests that Shilajit is a valuable supplement in supporting the body's defences, particularly in challenging health conditions like HIV.
In essence, Shilajit is a special and extremely safe dietary supplement, potentially able to combat the development of several diseases, but its main medical application now appears to come from its actions in benefit of cognition and potentially as a dietary supplement to prevent Alzheimer’s disease.
