Fish oil is very easy to use. You can take it:

• As capsules or softgels with water
  
  
• As liquid oil mixed with food or juice
  
  
• Always with a meal to improve absorption and reduce fishy burps
  
  

Some tips:

• Store in a cool place, away from heat and sunlight
  
  
• Choose high-quality brands with purified oil
  
  
• If it smells very fishy or tastes bad, it may be old or low-quality
  
  

Liquid forms are better for people who have trouble swallowing pills.

Fish oil contains two main omega-3 fatty acids:

• EPA (eicosapentaenoic acid)
  
  
• DHA (docosahexaenoic acid)
  
  

These healthy fats are anti-inflammatory, meaning they help reduce swelling and irritation in the body. Omega-3s also help:

• Lower triglycerides (a type of fat in the blood)
  
  
• Improve heart rhythm
  
  
• Support brain cell function
  
  
• Reduce stiffness in joints
  
  
• Keep skin and eyes healthy
  
  

The body cannot make enough omega-3s on its own, so we need to get them from food or supplements like fish oil.

Fish oil is usually safe for most people. Side effects are often mild and can be avoided by taking it with food.

Common Side Effects:

• Fishy aftertaste or burps
  
  
• Upset stomach
  
  
• Loose stools or diarrhea
  
  
• Nausea
  
  
• Mild rash (rare)
  
  

Serious Side Effects (rare):

• Increased bleeding risk in high doses
  
  
• Allergic reactions (if allergic to fish)
  
  
• Bad breath or body odor
  
  

If you experience easy bruising, nosebleeds, or severe stomach pain, stop using fish oil and talk to your doctor.

Fish oil is safe for most people, but some people need to be careful.

Pregnant women should choose a fish oil supplement specially made for pregnancy, with purified DHA and no mercury.

Always read the label and choose third-party tested products for safety and quality.
