Hemp Oil Side Effects: The Dark Side of Hemp Seed Oil

hemp oil side effects


We all know how beneficial hemp oil is and how it positively affects our body. It cures and prevents a number of diseases; it is used for cosmetic purposes and as a food supplement. But is it so safe to use and are there any side effects of hemp oil?

Polyunsaturated fatty acids can be up to 70% in the hemp oil. If to add this number to the number of PUFAs consumed daily (for example, an average American diet), this may affect your health negatively. PUFAs include Omega 3 and Omega 6, which also may be unhealthy, much to the surprise, because we all know that it is good to consume Omega 3. Yes, it is good, but only in moderate amounts. Speaking about Omega 6, our body cannot take too much of it, and inaccurate consumption may cause serious imbalance.

  • Brain development problems

Child and Family Research Institute discovered that for developing in culture, neurons require Omega 3. However, Omega 6 is not recommended, and thus, the consumption of hemp seed oil may result in fatty acid imbalance, which can lead to brain development problems.

IMPORTANT! 6 Fish Oil Side Effects You Should Be Aware of


  • Cardiac dysfunction

The University of British Columbia stated that a high-fat diet, rich in Omega 6, may develop cardiac dysfunction.

  • Immunosuppression

Dr Newsholme from Oxford University thinks that PUFAs greatly suppress our immune system, meaning the effectiveness and its activation is decreased. Even though PUFAs are considered to treat inflammatory symptoms, linked to cardiovascular diseases and arthritis, at the same time the suppression of immune system increases the receptivity to bacteria and infections.

  • Reproduction of tumor cells

Hemp seed oil is known to increase the reproduction of the cells, which normally help the body to heal. Therefore, it is effective for treating skin and other diseases. However, if a diet is rich in PUFAs and especially linoleic acid, promotion of cancer cells can also be observed (particularly prostate cancer). More research on this issue is still needed, but it is advised that if you have a risk of prostate cancer, you rather not consume hemp oil.

  • Diarrhea

If you consume hemp oil in high doses, it may cause diarrhea and abdominal pains.

  • Not suited for hot temperatures

You should not cook with hemp oil or heat it, as it turns unsaturated fats into saturated, which are less healthy.

As any other product, hemp oil has its side effects. But it doesn’t’ mean the oil should not be consumed at all, because as we know, it has a great number of health benefits. So don’t get scared by the side effects of hemp seed oil. But remember:  before starting to use it, either for medical or cosmetic reason, it is advised to visit a doctor for consultation and judge from the overall state of your health.
