Mercury and other heavy metals can enter the blood and cause kidney, liver and mental problems, as well as endangering the development of the fetus. The most common cause of high blood mercury levels are large fish, amalgam fillings, and air pollution from coal-fired power plants. Reducing mercury levels is usually a task best left to doctors, but there are some things you can do to remove mercury from your body if your levels have been found to be high.
Steps
Method 1 of 2: Reduce Mercury Through Drugs

Step 1. Make an appointment with your doctor to test your mercury levels
A normal blood count does not test for all types of mercury, but doctors can prescribe a drug that extracts mercury from the body in the urine. The urine will then be tested.
You can purchase a home test for measuring mercury, but if you are concerned about possible poisoning it is highly recommended that you undergo a professional medical examination

Step 2. Get chelation therapy if your mercury levels are dangerously high
The most common therapy is done with the injection of a synthetic amino acid and cannot be done at home.

Step 3. Ask for mercury-free vaccines
Getting flu shots and other preventative treatments is a good idea, as they keep the body in better health by allowing the mercury to drain naturally. However, some vaccines contain mercury and should be avoided with the knowledge of your doctor.

Step 4. Avoid the fish
In general, the larger the product from the sea, the greater the risk. Whales, sharks, tuna and other large fish carry high levels of mercury, due to the pollution of the water produced by the industries.
Method 2 of 2: Reduce Mercury at Home

Step 1. Eliminate certain varieties of fish from your diet
Eat only those fish whose size is smaller than that of your pan. Small reef fish, wild Alaskan salmon and herring appear to contain the lowest levels of mercury.

Step 2. Try cilantro as a detoxifier
Purchase or grow fresh cilantro. Take a large bunch and turn it into a pesto with garlic and extra virgin olive oil. Use it to season pasta and eat it for lunch or dinner.
Repeat for 5 to 7 days

Step 3. Try taking garlic juice every day for a week
A Korean study suggests that fresh garlic juice can help the body eliminate excess mercury.

Step 4. Eat a diet rich in protein and fat
The amino acids in proteins help the body eliminate mercury. Fats can also absorb heavy metals.
Avoid excess sugar, they can slow down the metabolism and weaken the immune system

Step 5. Exercise and eat healthily
In fact, the body is prepared to remove mercury. The healthier you are, the quicker its response will be.

Step 6. Use these methods in moderation
Mercury is slowly removed from the body. Trying to get rid of it too quickly can cause stomach upset and other health problems.
