The wellness landscape has seen an explosion of interest in CBD oil, with many people exploring its potential to support everyday balance, from promoting a sense of calm to aiding recovery. With this surge in popularity, a crucial question often emerges: is CBD oil bad for the liver? It's a valid concern, given the liver's vital role in metabolising everything we consume.
This article aims to thoroughly explore the current scientific understanding of CBD's interaction with the liver. We’ll delve into the research, discuss potential risks and benefits, and provide practical guidance on how to use CBD products responsibly and with confidence. Our mission at Swiss Peak Health is to offer in-demand wellness products that are more than hype, focusing on affordability, transparency, accessibility, reliability, and strong British quality controls. We believe that understanding the science behind your supplements is key to achieving peak health.
Understanding CBD and the Liver
To properly address whether CBD oil can negatively impact the liver, it’s helpful to first understand how our bodies process CBD and the liver's role in that process. The liver is a powerhouse organ responsible for detoxification, metabolism, and producing essential proteins. When we consume CBD orally, it enters our digestive system and is then absorbed into the bloodstream, travelling to the liver before circulating throughout the body.
The Liver's Metabolic Role
The liver contains a complex system of enzymes, particularly the cytochrome P450 (CYP450) enzyme family, which are crucial for metabolising many substances, including medications and supplements like CBD. These enzymes break down compounds into metabolites that can be eliminated from the body.
When CBD is metabolised by these enzymes, it can sometimes affect their activity. This interaction is a key area of scientific investigation, as changes in CYP450 enzyme activity could potentially influence how other medications are processed by the liver.
Unpacking the Research: What Studies Say
The question of CBD and liver health isn't new, and researchers have been actively investigating this relationship. It's important to distinguish between different types of CBD products and dosages when reviewing the evidence.
Early Concerns: High Doses in Clinical Settings
Initial concerns about CBD and liver health largely stemmed from clinical trials involving very high doses of a prescription CBD drug used for specific medical conditions, particularly in children with epilepsy. In these trials, some participants, especially those also taking other anti-epileptic medications, showed elevated liver enzymes.
Elevated liver enzymes like alanine aminotransferase (ALT) and aspartate aminotransferase (AST) can be an indicator of liver stress or inflammation. They are released into the bloodstream when liver cells are damaged. It's important to note that these studies involved significantly higher CBD dosages than those typically found in over-the-counter wellness supplements.
A Deeper Look: The FDA Trial and Its Implications
A recent, notable study carried out by scientists from the Food and Drug Administration (FDA)'s Division of Applied Regulatory Science aimed to assess how lower, more typical doses of oral CBD affect liver function in healthy adults. Over four weeks, participants received either a placebo or 5 mg per kilogram of body weight of oral CBD, which equates to roughly 350 mg for an average adult.
While the majority of participants were unaffected, approximately 5% showed elevated levels of aminotransferase, a marker of liver cell damage. A small number of participants withdrew from the trial due to clinical signs of potential drug-induced liver injury. Women in the study appeared to be more susceptible than men, and notably, the liver enzymes returned to normal within a week or two of stopping CBD use.
This study is significant because it suggests that even in the absence of other drugs, CBD itself, at typical consumer doses, may pose a risk to liver health for a small percentage of individuals. It highlights the importance of monitoring liver safety and underscores that users may not always realise they are experiencing harm, as symptoms may not be immediately apparent.
The ValidCare Study: A Broader Perspective on Self-Medication
In contrast to the FDA trial's findings, a large-scale observational study, the ValidCare Study, investigated the prevalence of elevated liver tests in an adult population self-administering CBD orally for a minimum of 30 days. This study involved over 800 participants using various forms of CBD (full-spectrum, broad-spectrum, and CBD isolate) at an average daily dose of 50.3 mg.
The findings from the ValidCare study indicated that the prevalence of elevated ALT and AST in self-medicating CBD users was not significantly different from the known prevalences in the general adult population. Most liver enzyme elevations observed were minor and often resolved, with only a very small percentage showing higher levels. The study concluded that self-medication of CBD does not appear to be associated with an increased prevalence of liver test elevation, suggesting that many such elevations might be linked to other existing conditions or medications.
Why the Different Outcomes?
The varying conclusions from these studies can be perplexing. Several factors might contribute to these differences:
- Study Design: The FDA trial was a controlled, placebo-randomised trial, designed to isolate the effects of CBD. The ValidCare study was observational, reflecting real-world usage but making it harder to definitively link CBD to liver changes over other factors.
- Participant Health: The FDA study recruited healthy individuals, while the ValidCare study included people taking CBD for various reasons, potentially with underlying health conditions or on other medications that could influence liver function.
- Dosage Specifics: While both studies aimed for "typical" doses, the precise methodologies and participant responses varied.
- Product Variability: The ValidCare study involved products from different companies, reflecting the diversity of the market. This can introduce variables in composition, even for products labelled similarly (e.g., full-spectrum).
Ultimately, the collective research suggests that while very high doses of CBD can undoubtedly affect liver enzymes, the impact of typical, lower doses used in wellness supplements is still being thoroughly investigated. For the vast majority of people, CBD appears well-tolerated, but a small subset may be more susceptible to elevated liver enzymes.
Potential Benefits of CBD for Liver Health (Indirectly)
While the focus often turns to potential risks, it's worth noting that some research suggests CBD might offer indirect support for liver health due to its well-documented properties. These are areas of ongoing research, and we avoid making any definitive claims, but understanding the scientific discussion is important.
Anti-inflammatory Properties
CBD is recognised for its potential anti-inflammatory effects. Inflammation plays a significant role in many liver conditions, including fatty liver disease. By helping to maintain a healthy inflammatory response, CBD may indirectly contribute to liver well-being.
Antioxidant Potential
Oxidative stress, an imbalance between free radicals and antioxidants in the body, can also damage liver cells. CBD is thought to possess antioxidant properties, which could help combat this stress.
Metabolic Regulation
Some studies explore CBD's potential influence on metabolic processes, such as the regulation of insulin, glucose, and lipids. These processes are all interconnected with the development of conditions like fatty liver.
It’s crucial to reiterate that these are areas of ongoing scientific inquiry, and more research is needed to fully understand any direct beneficial effects of CBD on liver health. We focus on providing products that support your everyday balance, from Energy collection to Sleep collection, without making unsubstantiated claims.
Key Considerations for Safe CBD Use and Liver Health
Given the nuanced scientific picture, how can you use CBD oil responsibly and support your liver health? Here are some practical steps and considerations.
Consult a Healthcare Professional
This is perhaps the most critical step. If you are pregnant or breastfeeding, taking medication, or under medical supervision for any health condition, especially liver conditions, always consult a healthcare professional before starting any new supplement, including CBD. They can provide personalised advice, review potential interactions with existing medications, and help you determine if CBD is appropriate for you.
For instance, CBD can interact with drugs metabolised by the liver’s CYP450 enzyme system, affecting their breakdown. This could lead to medications not working as intended or an increased risk of side effects. Examples of such medications may include blood thinners, anti-seizure medications, immunosuppressants, and certain antidepressants.
Start Low and Go Slow
When trying any new supplement, including CBD, the general advice is to start with a low dose and gradually increase it until you find what works for you. This approach allows your body to adjust and helps you gauge your individual response. Always follow the label recommendations for any product you use. Our CBD Oil 1500mg | 30ml or 500mg CBD Oil | 30ml Starter Strength are popular choices for those beginning their CBD journey.
Choose High-Quality, Transparent Products
The quality of your CBD product matters immensely. The market can be unregulated, and some products may not contain the amount of CBD claimed on the label or could contain undesirable contaminants. When sourcing CBD, prioritise transparency.

Be Mindful of Dosage and Product Type
Different CBD products come in various strengths and formats. An NMN NAD+ Gummies | 30 Pack or Lion's Mane Gummies | 2000mg 30 Pack will deliver CBD differently than a tincture like our 12000mg CBD Oil | 100ml High Strength. Pay close attention to the suggested serving sizes on the product label. Studies suggesting liver impact often involved very high daily doses, sometimes exceeding 1000 mg. While our products offer varying strengths, such as our 25000mg CBD Oil | 100ml High Strength, it's always important to use them as directed and discuss higher dosages with a professional.
Observe Your Body's Response
Pay attention to how you feel when you start using CBD. While serious liver injury symptoms are rare with over-the-counter CBD, signs can include abdominal discomfort, unusual fatigue, or yellowing of the skin or eyes. If you experience any concerning symptoms, discontinue use and seek medical advice immediately.
Support Overall Liver Health
Regardless of CBD use, maintaining general liver health is always a good practice. This includes:
- Balanced Diet: Eating a diet rich in fruits, vegetables, and whole grains.
- Regular Exercise: Engaging in physical activity consistently to support metabolic health.
- Moderate Alcohol Intake: Limiting or avoiding alcohol, as excessive consumption is a major contributor to liver stress.
- Staying Hydrated: Drinking plenty of water.
- Avoiding Toxins: Minimising exposure to environmental toxins where possible.
Incorporating other supplements that support overall wellness can also be beneficial. For example, Magnesium Citrate Tablets 750mg | 60 Servings can support sleep quality, and products from our Focus & Clarity collection can help support mental sharpness.
CBD for Pets
It's also worth noting that similar considerations apply to CBD products marketed for animals. The FDA has not approved CBD for any use in animals, and the concerns regarding unproven claims and unknown quality are equally relevant. If you're considering CBD for a pet, such as our 100ml Pet Oil or Meaty Treats (250mg), it is essential to consult with your veterinarian first.
