1. What is that heavy metals contamination in shilajit or other food ?
  2. What is the most contaminated products of my daily ration ?
  3. How to understand the numbers from the Certificate of Analyses ?

I answer those questions many times over the phone and email. And recently I saw the consumer warning for Ayurvedic shilajit made by Mike Adams the Health Ranger. Besides that our brand is listed as “far more appropriate” many people start to fear.

Lead in shilajit
Please review our Certificate of Analyses
Some of us fear the horrendous disaster, but when you know the chances, when and how it may happen you have a confidence that it won’t happen to you. You can take control on the situation and avoid that.

Does it Have Toxic Heavy Metals ?

Shilajit rich with trace metals and minerals like a fruit rich with vitamins. It has a full stack of trace elements including the metals with regulated limits for daily intake. Let’s pay attention on the certain metals which is Cadmium, Lead, Arsenic, Aluminum and Mercury.

All metals, except Mercury, naturally exist in our body. Organic plants do contain small amount of heavy metals because they are existing in the earth’s crust. But the industrial pollution nowadays is the most common way of food contamination. The excessive quantities of heavy elements can be toxic and may disrupt the cell functions that can lead to cancer or serious diseases.

Many foods contain heavy metals… Did you ever not buy a chocolate because it may have lead or shrimps because of arsenic ?

Types of Heavy Metals in Shilajit.


Trace metals is not the same as metallic ore or industrial metals. Trace means a small but measurable amount of element with is likely less than 0.1% or 1000ppm (parts per million).

We also call it organic metals because it formed in plant cells and tissues as a necessary part of their nutrition and physiology. (1) Organic metals are always covalently bonded with carbon, while most inorganic metals occur in their pure, metallic form, or in compounds where they bonded to other non-carbon elements.

The EPA regulations based on inorganic metals. The toxicity of the atom stems depends on how it disrupts the complex sequence of metabolic reactions in the body. But, when the metal atom is already bonded to other functional groups, in fact with carbon, it cannot react in the same way. For that reason, most organic metal compounds are far from being as toxic as the pure metal and may leave the body with the urine and feces. (12) (13)

Pure shilajit made from organic metals and that makes a difference. But I must say that being organic doesn’t mean to be safe and we still have to pay attention to the numbers.

Lets Reveal the Horrendous Truth !

The effects of exposure to any hazardous substance depend on the type, the amount or dose and duration or frequency of intake. (Dept. of Health)

PPB – stands for the range of parts per billion. It is equal to the value of one penny compared to that of 10 million dollars.
UG – Microgram, 1000 UG = 1 MG, 1000 MG = 1 GM, 28.3 GM = 1 OZ
USP – The US Pharmacopeia organization that determine elemental impurities in pharmaceutical products.
ATSDR – Agency for Toxic Substances and Disease Registry that determine the minimal risk level of metal for food intake.
California Prop 65 – the Safe Drinking Water and Toxic Enforcement Act of 1986 by the state of California.

Before viewing the actual numbers i would like show how i made the calculation.

First i did the research about any articles with the amount of heavy metal contamination for different products. It is far from ideal and some of the articles is old, please let me know if you can update my data with a better accuracy. You can always double check the results by using the heavy metal calculator.

A candy has 100 ppb (0.1 ppm) of lead with the average serving size of 12 gm so the total amount of consumed lead will be 0.1 x 12 = 1.2 ug. Our shilajit has 1670 ppb of lead with the single serving of 150 mg so the total amount of consumed lead will be 1.67 x 0.15 = 0.25 ug.

Lead - Pb

About 99% of the amount of lead taken into the body of an adult will leave in the waste within a couple of weeks. (ATSDR)

Mercury - Hg

Most mercury poisoning comes from air and water vapors (80%) then through the food. Most of the metallic mercury absorbed into the body and leaves in the urine and feces, while smaller amounts leave the body in the exhaled breath.

Aluminum - Al

A small amount of the aluminum you breathe will enter your body through your lungs. A very small amount of the aluminum in food or water will enter your body through the digestive tract. An extremely small amount of the aluminum found in antacids will be absorbed. A very small amount may enter through your skin when you come into contact with aluminum. Most aluminum in food, water, and medicines leaves your body quickly in the feces. Much of the small amount of aluminum that does enter the bloodstream will quickly leave your body in the urine.

Arsenic - As

Both inorganic and organic forms leave your body in your urine. Most of the inorganic arsenic will be gone within several days, although some will remain in your body for several months or even longer. If you exposed to organic arsenic, most of it will leave your body within several days.

Cadmium - Cd

About 5-50% of the cadmium you breathe will enter your body through your lungs. A small amount of the cadmium in food and water (about 1-10%) will enter your body through the digestive tract. Your body can change most cadmium to a form that is not harmful, but too much cadmium can overload the ability of your liver and kidney to change the cadmium to a harmless form.

How to Cut the Risk from Heavy Metals in Shilajit

Even if our shilajit is way below the warning flag you may still take the following steps to be super safe:

  • Pay attention on the maximum dose
  • Take it once or twice a day
  • Don not take it every day but 4 – 5 times a week, then your body have more time to adjust the certain metals in your blood and store the one it required.
  • Keep it away from the kids, the same way as a fluoride toothpaste or prescription drugs.

Imagine a person who does selective search for heavy metals in all food...

In case of any food but not only shilajit you have to revise the entire shopping list. First, we need to get the COA from all vendors and this would not be an easy task. As of my personal experience most of the companies in USA doesn’t test their products for heavy metals contamination. You either have to spend $150 for self-laboratory analyses or wait if they follow your request to do that.

It may surprise you but some products your family use for many years does have an alarming level of metals. You should avoid that if found but excluding all food with heavy metals would be a hard challenge that might not benefits your health at all. Plus, you have to avoid a lot of organic supplements including shilajit that may give you a benefit.

Many people start to fear shilajit like the horrendous disaster. We know that disasters are hitting certain number of people each ear but can you found a single clinical case or study about shilajit damage?

It is very unlikely to intoxicate yourself with Pure Himalayan Shilajit. Every single day you’ve got many times greater amount of heavy metals by eating food and drinking a water.
