Fish oil is one of the most common supplements in gym bags and kitchen cabinets, and also one of the most confusing to buy. Bottles show big numbers like 1000 mg, but that is not the number that matters. This guide explains what to look for, how much to take and what we stock. Prices vary by brand and size and change with imports and stock, so check each product page for the current price.

What omega-3 is

Omega-3 fatty acids are fats your body needs but cannot make. Fish oil supplies two of them, EPA and DHA. They are linked with heart health, brain function and normal inflammation, and some lifters take them for general recovery and joint comfort. Omega-3 supplements are not a performance booster. Think of them as general health support.

The number that actually matters

A capsule labelled 1000 mg fish oil does not contain 1000 mg of omega-3. Turn the bottle around and check the supplement facts for the amounts of EPA and DHA per serving. The combined total of those two is what you are really getting, and it is often well under the headline number.

How much to take

Many health bodies suggest a combined EPA and DHA intake of roughly 250 to 500 mg a day for healthy adults, which you can reach through fish or supplements. Some people take more under medical advice. Higher doses are not automatically better, and they can cause side effects. Use the label and your doctor as your guide.

How to compare them

1. EPA plus DHA per serving. This is the real comparison.
2. Servings per bottle. Divide the current price by servings to get cost per day.
3. Serving size. Some brands need two softgels to reach the stated amount.
4. Freshness. Check the expiry date and avoid bottles that smell strongly rancid.

How to take fish oil

• Take it with a meal that contains some fat, which helps absorption.
• Take it at the same time daily so you do not forget.
• If you get fishy burps, try taking it with dinner or keeping the bottle in a cool place.
• Store it away from heat and sunlight.

Safety

Fish oil is generally well tolerated by healthy adults. Check with your doctor first if you take blood thinners, have a bleeding disorder, have a fish or shellfish allergy, are pregnant or have a scheduled surgery. Mild side effects include fishy aftertaste, upset stomach and loose stools.

Do you need it if you eat fish?

If you eat oily fish like salmon, sardines or mackerel about twice a week, you may not need a supplement. Fish oil mostly helps people who rarely eat fish.

Omega-3 fish oil: common questions

Does fish oil build muscle?

Not directly. It supports general health, and training, protein and sleep drive muscle growth.

Can I take fish oil with creatine and whey?

Yes. They do different jobs and are commonly used together. See our guides to creatine and whey.

When is the best time to take it?

With a meal. The exact time is less important than being consistent.

Why does the price vary between brands?

Brand, EPA and DHA content, servings per bottle, quality and import costs all play a part.
