In this article we’ll discuss the topic of CBD oil side effects on kidneys – are there any?
There is still so much to explore when it comes to researching the potential effects and benefits of cannabidiol. For example, we recently wrote about an article exploring whether CBD could potentially help prevent COVID-19 infections.
Whenever you try a new supplement, it’s wise to read up about it first to make sure it’s right for you – are there any reported side effects, for example?
And we’re sometimes asked about whether there are any potential CBD oil side effects on kidneys, so let us clear that one up for you in this article.
First, a little context – before analysing if there are any CBD oil side effects on kidneys, it helps to understand the important roles these organs play in the body.
Kidneys remove waste and extra fluid, as well as acid produced by cells. In the bloodstream, they regulate a healthy balance of minerals, salts and water. The minerals include calcium, magnesium and phosphate.
Maintaining this balance is important because otherwise the muscles, nerves and tissues in the body may not function properly. Kidneys also make hormones which help control blood pressure.
In the UK, approximately 10% of the population have chronic kidney disease. This rises to 20% of people over 80 years old, according to Kidney Care UK.
If the kidneys stop working as well as they should, this could well be a sign of chronic kidney disease. At an advanced stage, symptoms could include a shortness of breath, blood in the urine, feeling sick, tiredness and swollen feet or hands.
Causes of chronic kidney disease include diabetes, high blood pressure, high cholesterol or infections.
Are there any CBD oil side effects on kidneys?
Some who worry about possible CBD oil side effects on kidneys have focused on a central concern – can any negative consequences arise from cannabidiol entering the bloodstream?
Taking it sublingually, by vaping, or by swallowing capsules allows cannabidiol to make its way through the bloodstream, in order to have a wide range of potentially positive effects.
In short, a 2020 nephrology review from a New York medical school concluded that “there is no evidence to suggest that CBD has any adverse effect on kidney function” – but more research is needed.
The review also mentioned a tentative indication that CBD could potentially support kidney function, referring to an example of preventing nephrotoxicity (kidney deterioration) in mice.
It’s important to note that the reported absence of CBD oil side effects on kidneys is always based on a key assumption – that the product is a correctly-labelled, reputable one. More on this shortly.
What are the effects of taking CBD oil?
What is the purpose of CBD’s absorption into the bloodstream? Again, research is ongoing and there is still much to learn about cannabidiol’s efficacy, but early results are very interesting.
They suggest that CBD could help to alleviate symptoms from several neurological as well as physical and psychological conditions, including:
- Anxiety disorders
- Chronic pain
- Multiple sclerosis
- Parkinson’s disease
Technically, cannabidiol interacts with the human body’s endocannabinoid system (ECS). A critical part of homeostasis, it’s a physiological system which helps regulate the body and maintain a healthy balance throughout.
CBD’s impact on the ECS is to prevent endogenous – or natural – endocannabinoids from breaking down, in turn helping them to have a bigger impact.
So if there aren’t any reported CBD oil side effects on kidneys, are there any other side effects elsewhere? Most people’s bodies tolerate it very well, although some users have felt drowsiness, fatigue, dizziness, a dry mouth and a reduced appetite.

CBD oil and quality control
For the best experience when taking CBD, it’s important to only buy quality, well-trusted products from reputable providers. This will help reduce any potential risk of harmful adverse side effects.
Sadly, there are many poor quality products available on the market, so trust is vital – some brands are, either knowingly or unknowingly, mislabelling CBD products.
For peace of mind, always read customer reviews and check the list of ingredients.
If a company claims their CBD products are legal since they contain less than 0.2% THC, they have misinterpreted UK law. The 0.2% legal limit for THC is only for the growth of CBD, not consumption.
Also look for third-party lab certificates on the provider’s website. CBD products should have essentially no THC – this can be verified by ISO-accredited labs with 0.01% detection limits.
Remember that in terms of the aforementioned studies looking into possible CBD oil side effects on kidneys and reportedly not finding any, that conclusion is based on a user taking legitimate cannabidiol products. In contrast, the presence of THC could potentially negatively impact results.
Summary: CBD oil side effects on kidneys
Preliminary studies have not found signs of CBD oil side effects on kidneys.
These organs regulate a healthy balance in the blood and while cannabidiol – when absorbed – enters the bloodstream, no evidence of adverse harm has been reported so far.
Bear in mind though that in order to be comprehensive, more research is needed and these findings assume that the CBD used is a legitimate product. For further information about whether there are any CBD oil side effects on kidneys please get in touch.
