Can Workout Supplements Cause Elevated Liver Enzymes?

A new study has suggested that workout supplements can cause elevated liver enzymes. Learn more about this study and how it could impact your health.


In the past few decades, exercise has seen rapid advances in technology and science-based developments, resulting in improved health and performance for those who partake in physical activity. As with any new innovation, there are often concerns about possible risks of taking part. With regards to taking workout supplements, an increasingly common question among consumers is whether these can cause elevated liver enzymes.

The liver acts as a filter for our body and is responsible for a variety of biochemical pathways. Elevation of its enzymes is a sign of potential damage or disease, which may lead to serious issues if left untreated. Therefore, it is important to understand the potential link between consumption of fitness supplements and higher amounts of liver enzymes to ensure that health and safety guidelines are followed when taking these products.

What Are Elevated Liver Enzymes?

Elevated liver enzymes are a sign of damage to the liver, and it is important to identify the cause. Elevated liver enzymes can be caused by a variety of medical conditions and medications, including certain types of workout supplements.

When your body is working properly, enzymes released by the liver help break down fats, proteins, carbohydrates, and toxins in food. Signs that enzyme levels may not be within normal limits include abnormal blood tests showing either too few or too many enzymes. High levels of these enzymes in the blood are referred to as elevated liver enzymes.

Understanding precisely why elevated liver enzymes occurred is important because its resolution depends on identifying the underlying cause. Liver injury is usually reversible if detected early enough in its course and treated appropriately; however, if left untreated, the consequences can be serious such as cirrhosis or even hepatic failure with life-threatening repercussions. It’s crucial to understand that even highly ranked workout supplements can induce significant changes in enzyme levels, potentially leading to elevated liver enzymes.

Types of Workout Supplements

Workout supplements come in many forms, such as protein powders, energy drinks, and pre-workout formulas. These are designed to help athletes gain muscle and strength, improve overall performance, and enhance recovery time. While they can be beneficial, they can also have some side effects, including elevating liver enzymes. In this article, we’ll discuss the different types of workout supplements, the possible side effects, and how to avoid them.

Protein Powders

Protein powder is the most popular form of nutritional supplement. It’s available in a range of different types, including whey and plant-based varieties. Whey protein is derived from cow’s milk and has one of the highest concentrations of protein, making it an ideal supplement to help build muscle mass and increase weight loss. Other animal sources used in some forms of protein powder include egg, casein, and soy-based proteins. Plant-based proteins are typically derived from peas or rice and are often used to supplement vegetarian or vegan diets with adequate protein intake.

Protein powders have many benefits when included as part of a balanced diet plan and in moderation can help to decrease hunger levels and increase muscle growth when paired with strength training. Generally speaking, it’s important to stick within recommended dosage levels for any kind of supplement as too much could result in elevated liver enzymes release which could lead to further health problems if left untreated. This can even be the case for plant-based proteins which contain relatively low amounts of leucine, an amino acid known for having a potential negative effect on liver enzyme production if consumed in excessive quantities. Ultimately it’s best to consult a qualified doctor before heavily doubling down on any type of workout nutrition supplement or other drugs as using such supplements in excess could have damaging effects if not properly managed by professionals with knowledge around this area.

Pre-Workout Supplements

Pre-workout supplements, also known as “ergogenic” or performance-enhancing supplements, have become increasingly popular among people who are looking for an energy boost before their workouts. While these supplements can be effective, it’s important to understand how they work and the potential side effects that may come along with them.

Pre-workout supplements typically contain a blend of stimulants such as caffeine, guarana, taurine and B vitamins, as well as creatine and other ingredients such as amino acids or hormones. Each of these substances has its own benefits and drawbacks depending on how it is used. The main purpose of taking pre-workout supplements is to increase energy levels in order to power through a vigorous workout or to help an athlete push harder and longer during competition.

Caffeine is the most common ingredient in pre-workout formula; its stimulant properties helps give users the energy they need to perform better during a workout session. Caffeine can be effective for some people but it can cause harmful side effects when used at high doses including dizziness, anxiety and insomnia.

Creatine is another commonly used ingredient that increases energy levels by allowing athletes to make more powerful movements when training with resistance exercises such Guarana is often added for its ability to reduce fatigue; Taurine provides cell hydration; B vitamins provide extra energy needed for muscle metabolism; Amino acids provide crucial building blocks for protein synthesis in muscles; Hormones like testosterone are sometimes added to help improve performance.

When taken properly pre-workout supplements can provide beneficial results such as increased endurance, improved strength and better muscle growth. However, improper use of these products combined with incorrect dosing has been linked to many health problems including elevated liver enzymes because the body struggles to process all of the unnatural ingredients found in many pre-workout formulas today. For this reason it’s important that users do adequate research before using them and follow dosage instructions carefully – if any are provided – having regular medical checkups done is also recommended so any potential health issues can be detected early on.

Creatine Supplements

Creatine is a type of workout supplement that has gained popularity in recent years. Creatine is found naturally in some foods, such as salmon, tuna, and beef. As a workout supplement, it may help increase muscle strength and boost athletic performance by providing additional energy to muscles. There has been concern about whether creatine can cause an elevation in liver enzymes or lead to other adverse effects on the liver. While it is possible for high doses of creatine to cause elevations in liver enzyme levels, research suggests that this is unusual and rare. Studies have not found that regular use of creatine has any long-term impact on basal enzyme levels, so it appears to be safe for healthy individuals when taken as directed on the label.

Potential Risks of Supplements

Workout supplements have become increasingly popular in recent years, however, there may be some potential risks associated with using them. One such risk is the potential for elevated levels of liver enzymes in users of the supplements. In this section, we’ll delve into the potential risks of using workout supplements and discuss whether or not these risks are worth it.

Inadequate Labeling

Inadequate labeling is one of the primary risks associated with dietary and workout supplements. Although dietary supplement makers have to register their products with the Food and Drug Administration (FDA), they are not subject to the same testing or review that must be conducted to approve a new drug. This lack of oversight means that supplement manufacturers do not need to provide a complete list of ingredients on their labels, making it challenging to assess potential risks associated with them.

In addition, ingredients that are listed may not be accurately represented due to potential discrepancies between declared amounts on the label and actual amounts in the product. This poses a significant risk for long-term health as consumers may mistakenly believe that they are receiving appropriate levels of beneficial ingredients and/or be unaware of potentially harmful ingredients included in supplements.

Furthermore, many workout supplements also contain added vitamins, minerals, amino acids or other herbal components that have yet to be evaluated by the FDA for safety. Without adequate information about usage and safety, consumers may end up ingesting more than recommended doses, thus putting themselves at risk for significant medical issues such as elevated liver enzymes, hypertension and cardiac arrhythmia.

Contamination of Supplements

Many of the common supplements used to improve physical performance contain contaminants. High-performance supplements are often packaged in a way that increases their chances of becoming contaminated with microbes, heavy metals, and other compounds. While the amount of contamination in supplement products is typically small, prolonged exposure to these contaminants can cause liver toxicity and elevated liver enzyme levels.

Every year new adulterated health products enter the market. The sheer number of dietary supplement manufacturers means there’s a greater chance for contamination with drugs not declared as an ingredient intended for human consumption. Adulterated supplements range from those spiked with controlled substances to steroids marketed as performance enhancing drugs. These chemical agents can put athletes at risk for different types of health problems such as fatigue and anxiety, elevated liver enzymes and even organ damage.

Supplements can also be contaminated with microbes like E. coli and salmonella, which can cause serious digestive issues like nausea or vomiting if ingested in sufficient quantities. Heavy metals such as lead and arsenic have been detected in some dietary supplement products as well, primarily due to incorrect storage or through presence/contamination in raw ingredients used during production/manufacturing process; these are especially concerning due to their ability to accumulate within the body over time and cause long-term health problems such as kidney or neurological damage if consumed at high levels over a period of time.

It’s important for athletes to do their research before using any type of supplement product in order to ensure its safety and efficacy – this includes asking the manufacturer directly about any potential contaminants that could be present within their products. It’s also important for athletes to practice safe storage techniques when handling supplementation products; this includes avoiding extreme temperatures that could increase microbial content which may then lead to harmful levels of contamination within the product itself over time.

Research on Supplements and Liver Enzymes

Research in the field of nutrition and sport supplements has increased significantly in recent years as consumers are looking for alternatives to performance-enhancing drugs. However, the use of supplements can put added stress on the liver, potentially leading to an elevation in liver enzymes.

When it comes to workout supplements, there are several components that could lead to elevated liver enzymes. Most supplementation products contain herbal and vitamin ingredients at high doses or in combination with other compounds. This can lead to toxicity or drug metabolism impairment, ultimately causing hepatic damage and elevated liver enzymes.

In addition, some supplement products may contain illegal components such as anabolic agents which can be harmful to the liver and lead to elevated enzymes. Athletes should be cautious when purchasing nutritional supplements without consultation from a health care professional, as these products have not been government regulated like conventional medications.

Finally, herbal or alternate medicines have been known to cause hepatotoxicity due to their active ingredients that manipulate hormones and fatty acids leading towards damages within the hepatic tissue. Consumers should pay attention for symptoms such as fatigue eyes turning yellow indicative of jaundice or pain in upper right side before resorting to taking any type of workout supplement or medication found over the counter.


In conclusion, while consuming workout and health supplements can lead to an increase in liver enzyme levels, the risk seems to be pretty low. Only when taken in very high doses over a long period of time, or when taken with other drugs, is there a noticeable increase in liver enzymes. If you decide to take any type of supplement, make sure that you get advice from your doctor first, follow the recommended dosage and exercise caution. Taking more than the recommended dosage may put you at risk for elevated liver enzymes and other potential health risks. Additionally, it is always important to remember that most dietary supplements are not approved by the FDA for safety or efficacy and could potentially be of poor quality due to lack of regulation.
