As of Jul 2026, Unbox Health has lab tested and rated 6 products in the Shilajit Supplements category.
We buy every product from the open market, with no brand involvement. Every product is tested at up to 3 NABL-accredited labs. Products are then rated D to A+, based on the following dimensions: their label accuracy, their toxicity and their nutritional profile (in the case of food products). All lab reports are published.

Shilajit is a resinous substance formed over centuries from decomposed plant matter in Himalayan rocks. Its primary active component is fulvic acid, which may support cellular energy metabolism and mineral absorption. Some research also associates it with antioxidant and anti-inflammatory properties. ICMR-NIN has not issued specific dietary guidelines for Shilajit or fulvic acid. It is widely used in both traditional Ayurvedic medicine and modern health supplements.
Purified shilajit is generally considered safe for healthy adults at doses of 300 to 500 mg per day, based on available clinical studies. The key safety concern is contamination: raw or unprocessed shilajit may contain heavy metals including lead, arsenic, or mercury. People with kidney disease, liver conditions, or those who are pregnant should be careful about choosing to take it. FSSAI requires heavy metals testing for all shilajit products sold in India.
Yes, women can take Shilajit Supplements. Research on shilajit in women is limited, but some studies suggest it may support energy levels and iron absorption. Women who are pregnant or breastfeeding should avoid it due to insufficient safety data. ICMR-NIN has not issued specific guidelines for shilajit use in women. Those with thyroid conditions or hormonal disorders should consult a doctor before starting.
Some clinical studies have associated purified shilajit supplementation with modest increases in testosterone levels in healthy adult men. However, current evidence is limited and most studies have small sample sizes. Shilajit is not a medical treatment for low testosterone. ICMR-NIN has not issued any recommendations on shilajit and testosterone. If you are considering it for hormonal support, get hormone levels tested and consult a doctor first.
Shilajit is not a weight-loss supplement. Current evidence does not establish a causal link between shilajit use and significant fat reduction. Some research suggests it may support energy metabolism and reduce exercise-related fatigue, which could indirectly support a fitness routine, but this is not the same as causing weight loss. ICMR-NIN has not issued any recommendations on shilajit for weight management.
ICMR-NIN has not established a formal dosage guideline for Shilajit. Internationally, clinical studies have typically used 300 to 500 mg of purified shilajit per day. As a practical guide, most products recommend starting at 300 mg daily and not exceeding 500 mg without medical advice. Doses above this range have not been well-studied for long-term safety. Always follow the dosage instructions on your product label.
Resin is a more concentrated form with higher fulvic acid content, while capsules offer standardized dosing and convenience. Both can be effective if the shilajit is purified and of good quality. The fulvic acid percentage is the key quality indicator, not the form. Before buying, check Unbox Health's lab-tested data to verify whether declared fulvic acid content matches actual tested levels across brands.
Most commonly, shilajit is taken in the morning on an empty stomach or with warm water, which may support absorption. Some people take it before exercise for potential energy benefits. ICMR-NIN has no specific guidance on timing. Consistency of daily use matters more than the exact time. Avoid taking it close to bedtime, as some users report it may interfere with sleep at higher doses.
Genuine purified shilajit resin should dissolve fully in warm water and feel slightly sticky, not brittle. More reliably, look for third-party lab test certificates that show fulvic acid content and confirm the absence of heavy metals. Unbox Health independently tests Shilajit Supplements and publishes results, so you can verify actual fulvic acid content and check whether products contain undeclared contaminants before buying.
There is no single best Shilajit Supplement. Quality varies widely between brands, and the most important factors are fulvic acid content and purity from heavy metals. Lab-tested data shows significant variation across products currently sold in India. Check Unbox Health's independently tested ratings to compare actual fulvic acid percentages and label accuracy across Shilajit Supplements, and identify which brands deliver what they claim.
