Shilajit is a naturally occurring, dark resin-like substance formed over centuries from decomposed plant and organic matter in mountainous regions, primarily the Himalayas and Central Asia. It contains a complex mixture of fulvic acid, humic substances, over 80 trace minerals in ionic form, and dibenzo-alpha-pyrones. Modern research has investigated its potential role in energy metabolism, cognitive health, physical performance, and healthy ageing. At Aiku, Shilajit is included in Cognition as a concentrated 10:1 extract at 374mg per serving, alongside Lion's Mane and B vitamins.
What Does Shilajit Contain?
Shilajit’ s profile is unlike most supplement ingredients. Key constituents include fulvic acid typically 60–80% of purified Shilajit, which acts as a natural carrier molecule, enhancing the absorption of minerals and nutrients at the cellular level. It also contains humic acid, which supports gut health; dibenzo-alpha-pyrones (DBPs), which have been investigated for their role in mitochondrial energy production; and over 80 trace minerals in ionic forms including magnesium, iron, zinc, copper, manganese, calcium, potassium, and selenium.
It is important not to think of Shilajit simply as a mineral supplement. Its biological properties are thought to arise from the interaction of multiple compounds across different pathways rather than from any one mineral alone. Composition also varies substantially between sources, which is why standardisation and testing matter.
What Is Fulvic Acid and Why Does It Matter?
Fulvic acid has attracted scientific interest because of its ability to interact with minerals and other compounds, and its potential role in nutrient transport across cell membranes. You may see Shilajit products marketed around fulvic acid as though it is the sole active ingredient, the reality is more nuanced. Shilajit is a complex natural material, and researchers are still working to understand how its different constituents contribute to its biological effects. It is more accurate to describe it as a phyto-mineral complex than simply a source of fulvic acid.
What Does the Research Say?
Research has investigated Shilajit for energy metabolism and mitochondrial function. A 2019 study found that Shilajit supplementation supported mitochondrial function in skeletal muscle, with implications for physical energy and recovery. A study published in Andrologia (Pandit et al., 2016) found significant improvements in testosterone levels and sperm quality in men taking purified Shilajit over 90 days versus placebo. Research published in the International Journal of Alzheimer's Disease suggests fulvic acid may help prevent the aggregation of tau proteins; a hallmark of cognitive decline associated with ageing. Laboratory and animal studies have also identified antioxidant activity from fulvic substances and DBPs.
Key Benefits of Shilajit
Support cellular energy and mitochondrial function
Shilajit’ s dibenzo-alpha-pyrones have been investigated for their role in the mitochondrial electron transport chain to the cellular machinery responsible for energy production. This is why Shilajit is included in cognitive and performance formulations targeting sustained energy rather than stimulant-driven output.
Supports mineral bioavailability
Fulvic acid acts as a natural transport molecule, carrying minerals and other compounds across cell membranes. This makes Shilajit valuable not just for what it contains but for how those compounds are delivered and absorbed.
May support cognitive health and healthy ageing
Emerging research into fulvic acid's potential role in tau protein regulation places Shilajit in a growing area of longevity science focused on brain health. Combined with its antioxidant mineral content, it contributes to a broader approach to healthy ageing at the cellular level.
Has antioxidant and cellular activity
Laboratory and animal studies have identified antioxidant properties from several Shilajit constituents. These findings help explain continued research interest in the context of healthy ageing, though laboratory activity does not automatically translate into a demonstrated human benefit.
Why Quality Matters
This is one of the most important things to understand before choosing a Shilajit supplement. Because Shilajit is collected from geological environments, its mineral composition varies and unwanted elements including lead, arsenic, mercury, and cadmium can be present in raw or inadequately processed material. This does not mean all Shilajit is unsafe. It means purification and testing are non-negotiable.
A quality Shilajit supplement should demonstrate: appropriate purification of raw material, heavy metal testing, batch-level testing, clear dosage information, and transparent sourcing. "Pure" on a label is not evidence of safety. Testing is.
What Does "Purified Shilajit" Mean?
Raw Shilajit should not be consumed without appropriate processing. Purification removes unwanted materials and contaminants while retaining the active compounds. The exact process varies between manufacturers, which is why consumers should look beyond label claims and ask what testing supports them.
How Aiku Uses Shilajit
Shilajit is a key ingredient in Aiku Cognition. Aiku uses a 10:1 concentrated extract at 374mg per serving, combined with Lion's Mane and B vitamins as part of a broader cognitive support formulation. A 10:1 extract ratio means the equivalent of ten parts raw material was used to produce one part extract, providing greater concentration than standard powder. Extract ratio is useful context, but not the whole picture: raw material quality, extraction process, standardisation, and testing all determine the final value of the ingredient.
The goal is not to position Shilajit as a magic ingredient or an instant booster. It forms part of a nature-first formula designed around sustained cognitive wellbeing and everyday mental performance.
Is Shilajit Safe?
Purified, standardised Shilajit is considered safe for healthy adults at recommended doses. Raw or inadequately tested Shilajit is a different consideration, heavy metal contamination is a genuine risk with poor-quality products. Shilajit is not recommended during pregnancy. Those with haemochromatosis, kidney conditions, or taking medication should consult a healthcare professional before use.
What to Look For When Buying Shilajit
Don't only look for the word "pure." Look for evidence of purification and processing, heavy metal testing results, batch-level testing, clear extract ratio and dosage information, and transparent sourcing. The manufacturer should be able to explain where the ingredient comes from and how it is processed.
