A standard fish oil capsule contains around 10-15 calories, primarily from healthy fats such as omega-3 fatty acids, which are beneficial for heart, brain, and joint health.
Calories in a Fish Oil Capsule | What’s Inside?
Fish oil supplements are a popular way to increase omega-3 fatty acid intake, especially for those who don’t consume enough fatty fish like salmon or mackerel. Each capsule is packed with healthy fats that support numerous bodily functions, but how many calories do they add to your daily intake? A single fish oil capsule generally provides 10-15 calories, depending on the brand and the amount of oil contained. Let’s dive into the nutritional value, health benefits, and other considerations when taking fish oil capsules.
Nutritional Profile of a Fish Oil Capsule
Here’s what you can typically expect in one fish oil capsule (1,000 mg):
- Calories: 10-15 kcal
- Total Fat: 1-1.5 grams
- Omega-3 Fatty Acids: 300-600 mg, including:
- Eicosapentaenoic Acid (EPA): 180-300 mg
- Docosahexaenoic Acid (DHA): 120-250 mg
- Other Fats: Trace amounts of monounsaturated and saturated fats
The calorie content in fish oil capsules comes entirely from fats, particularly omega-3s. These are essential fats that the body cannot produce on its own and must be obtained through diet or supplements. Omega-3s are well-known for their role in reducing inflammation and promoting heart health.
How Fish Oil Calories Fit into Your Diet
- Daily Caloric Impact: Taking one or two fish oil capsules a day won’t significantly impact your calorie intake, even if you are on a strict diet. The 10-30 calories per day are relatively negligible but provide substantial health benefits.
- Healthy Fats: Unlike trans or saturated fats, the fats in fish oil are considered heart-healthy. They support cardiovascular health, improve cholesterol levels, and may even help with weight management when incorporated into a balanced diet.
- Fat Solubility: Omega-3 fatty acids are fat-soluble, which means they are better absorbed when taken with a meal that contains some dietary fat. This can maximize the benefits of the supplement.
Health Benefits of Fish Oil Capsules
- Cardiovascular Health: Omega-3 fatty acids in fish oil help reduce triglycerides, lower blood pressure, and prevent the buildup of plaque in the arteries. The American Heart Association recommends omega-3s for reducing the risk of heart disease.
- Brain Function and Mental Health: DHA, one of the main components of fish oil, is crucial for brain health. It has been linked to improved cognitive function and may help reduce symptoms of depression and anxiety.
- Joint and Bone Health: Fish oil’s anti-inflammatory properties make it beneficial for people with arthritis or other joint-related issues. It may help reduce joint pain and stiffness and improve overall joint function.
Types of Fish Oil Supplements and Their Caloric Content
The calorie content of fish oil capsules can vary based on the type and concentration. Here’s a look at different forms:
- Standard Fish Oil Capsules: Contain 1,000 mg of fish oil with 300 mg of omega-3s, totaling about 10-15 calories.
- Concentrated Omega-3 Capsules: Provide higher doses of omega-3s (up to 600 mg) and may contain 15-20 calories per capsule.
- Cod Liver Oil: In addition to omega-3s, cod liver oil contains vitamins A and D. A teaspoon serving has about 40 calories, significantly more than a single capsule.

Potential Drawbacks and Considerations
While fish oil capsules offer numerous health benefits, there are some considerations to keep in mind:
- Calorie Contribution: While minimal, the calories from fish oil capsules can add up if you’re taking multiple doses per day. For those on a calorie-restricted diet, it’s something to consider.
- Purity and Quality: Not all fish oil supplements are created equal. Low-quality fish oil may contain impurities like mercury or other toxins. Always choose a high-quality brand that tests for purity and potency.
- Possible Side Effects: Some people may experience mild side effects such as fishy burps, stomach upset, or an aftertaste. Enteric-coated capsules can help minimize these issues.
How to Incorporate Fish Oil Capsules into Your Routine
- Timing and Absorption: It’s best to take fish oil capsules with a meal that includes healthy fats, such as avocado, nuts, or olive oil, to improve absorption. Taking them with breakfast or dinner can also make it easier to remember.
- Dosage Recommendations: The recommended dosage varies depending on your health goals. For general wellness, 250-500 mg of combined EPA and DHA per day is sufficient. Higher doses may be recommended for people with heart conditions or high triglycerides.
Comparing Fish Oil to Other Sources of Omega-3s
Omega-3s can be obtained from various sources, not just fish oil. Here’s how fish oil compares to other popular omega-3 sources:
- Flaxseed Oil: A vegetarian source of omega-3s, primarily alpha-linolenic acid (ALA), which the body partially converts to EPA and DHA. It contains about 120 calories per tablespoon, much higher than fish oil capsules.
- Chia Seeds: Another plant-based source, providing 5 grams of ALA per ounce and around 140 calories. Chia seeds are versatile and can be added to smoothies or salads.
- Walnuts: A handful of walnuts (about 1 ounce) provides 2.5 grams of ALA and around 185 calories, making them a nutritious but calorie-dense option.

FAQs – Calories in a Fish Oil Capsule
How many calories are in a 1,000 mg fish oil capsule?
A 1,000 mg fish oil capsule typically contains 10-15 calories. The exact number depends on the concentration of omega-3 fatty acids, as well as any additional ingredients included in the capsule, such as flavorings or preservatives.
Are fish oil calories significant enough to impact my diet?
No, the calories in fish oil capsules are generally negligible. Even if you take 2-3 capsules daily, it only adds about 30-45 calories to your diet. These calories come from healthy fats, which can be beneficial when consumed as part of a balanced diet.
How many fish oil capsules should I take per day?
The recommended dosage varies based on your health needs. For general wellness, 1-2 capsules (providing 250-500 mg of combined EPA and DHA) per day is usually sufficient. Higher doses may be recommended for specific health conditions, such as heart disease or high triglycerides. Always consult with your healthcare provider for personalized advice.
Can I get omega-3s from food instead of fish oil capsules?
Yes, omega-3s are abundant in foods like fatty fish (salmon, mackerel, sardines), chia seeds, flaxseeds, and walnuts. Consuming these foods regularly can provide the necessary omega-3 fatty acids without needing supplements, unless dietary restrictions or health conditions make it challenging to get enough from food alone.
Does taking fish oil capsules increase body fat?
No, taking fish oil capsules in moderation does not lead to body fat gain. The fats in fish oil are healthy omega-3s, which can actually support fat metabolism and have anti-inflammatory properties. Weight gain occurs when there is an excess of calories from all dietary sources, not from taking small amounts of healthy fats.
Are there any side effects from the calories in fish oil?
The calories in fish oil are too minimal to cause side effects related to weight gain or significant changes in metabolism. However, some people may experience gastrointestinal discomfort or fishy burps from taking fish oil. Using enteric-coated capsules or taking them with meals can minimize these issues.
Can fish oil capsules replace eating fish in my diet?
While fish oil capsules provide essential omega-3 fatty acids, they do not offer the complete nutritional benefits of eating fish. Whole fish provides additional nutrients, such as vitamin D and high-quality protein. It’s best to consume both fish and supplements for a well-rounded intake, especially if you have dietary restrictions.
What should I look for in a high-quality fish oil supplement?
Choose fish oil supplements that are certified for purity and potency by third-party organizations, such as the International Fish Oil Standards (IFOS). Look for products that state they are free from heavy metals, like mercury, and use wild-caught fish as the source. Opt for capsules that contain higher concentrations of EPA and DHA for maximum benefits.
How do fish oil calories compare to other fat supplements?
Fish oil capsules have fewer calories compared to fat supplements like coconut oil or MCT oil. A tablespoon of coconut oil contains about 120 calories, while a 1,000 mg fish oil capsule only has 10-15 calories. Fish oil provides specific health benefits from omega-3s, while other oils are more calorie-dense and serve different nutritional purposes.
Can fish oil capsules help with weight loss despite the calories?
Yes, fish oil may support weight loss in some cases. The omega-3s in fish oil can improve fat metabolism and reduce inflammation, which may aid in weight loss efforts when combined with a healthy diet and exercise. The minimal calories in fish oil capsules are not a concern and may even support a balanced metabolic function.
Conclusion: Understanding the Calories in Fish Oil Capsules
Fish oil capsules are a low-calorie way to boost your intake of omega-3 fatty acids, with only 10-15 calories per capsule. These calories come from healthy fats that support heart, brain, and joint health. Incorporating fish oil into your daily routine can provide numerous benefits without significantly impacting your calorie intake. Whether you’re looking to improve cardiovascular health or support brain function, fish oil capsules are a valuable addition to a well-rounded diet.
