Benefits of Fish Oil
Fish oil contains Omega-3 fatty acids, mainly EPA and DHA. These are essential fatty acids that the body cannot produce in sufficient amounts, so they need to be obtained from food or supplements.
EPA and DHA have different roles in the body:
|
Omega-3 Fatty Acid |
General Role |
|
EPA |
Supports general wellness and healthy circulation |
|
DHA |
Supports brain and eye development, especially during growing years |
For children, getting enough Omega-3 from daily meals can sometimes be difficult, especially if they do not like fish or have a selective eating habit. This is why some parents choose fish oil supplements as part of their child’s daily nutrition routine.
What Should You Not Take with Fish Oil?
Fish oil is best taken with meals, especially meals that contain some healthy fats. This helps improve absorption and may reduce fishy burps or stomach discomfort.
However, it is generally better to avoid taking fish oil at the same time as the following foods and drinks.
1. Coffee, Tea and Certain Drinks
Coffee and tea contain compounds such as caffeine and tannins. Some fruit juices also contain plant compounds that may affect how nutrients are absorbed.
For best results, take fish oil with plain water and avoid taking it together with coffee, tea or fruit juice.
A practical suggestion is to leave a gap of around 1 to 2 hours between fish oil and these drinks.
2. Very High-Fibre Foods or Fibre Supplements
Dietary fibre is important for digestive health. However, when taken at the same time as oil-based supplements, very high amounts of fibre may affect fat absorption.
Examples of high-fibre foods include:
- Large amounts of vegetables
- Fruits
- Brown rice
- Oats
- Fibre powders or fibre supplements
This does not mean children should avoid fruits and vegetables. It simply means that fish oil is better taken with a regular meal, while very high-fibre foods or fibre supplements can be taken at a different time.
Can Fish Oil and Calcium Be Taken Together?
Yes, fish oil and calcium can generally be taken on the same day. However, it may be better to take them at different times for better comfort and absorption.
A common misunderstanding is that fish oil and calcium will create a “soap-like reaction” in the body. This is not accurate. Such a reaction requires special chemical conditions and does not happen in the human digestive system in the same way.
Still, fish oil and calcium supplements have different absorption needs.

Suggested Timing |
Practical Tip |
|
Fish Oil |
With meals or after meals |
Taking it with food can support absorption and reduce fishy aftertaste |
|
Calcium Supplement |
With food or as directed on the product label |
Some forms of calcium are better absorbed with meals |
If your child or family member is taking several supplements daily, it is a good idea to space them out by 1 to 2 hours. This helps make the routine more comfortable and easier to follow.
For children, elderly adults, pregnant women or anyone with a medical condition, always check with a doctor, pharmacist or nutritionist before combining several supplements.
What Medicines Should Not Be Taken with Fish Oil?
Fish oil is a supplement, but it may still interact with certain medicines. This is especially important if your child or family member is taking medication regularly.
1. Blood-Thinning Medicines
People who take blood-thinning medicines such as aspirin, warfarin or other anticoagulants should be careful with fish oil supplements.
Omega-3 fatty acids may affect blood clotting. While normal supplement use is usually well tolerated by many people, those taking blood-thinning medicines should consult a doctor before taking fish oil.
2. Non-Steroidal Anti-Inflammatory Drugs, Also Known as NSAIDs
Common NSAIDs include ibuprofen and other anti-inflammatory or pain relief medicines.
If fish oil is taken together with NSAIDs, especially in higher amounts, there may be a higher chance of stomach discomfort or bleeding risk for some individuals.
If your child is taking fever or pain medicine, it is best to ask a doctor or pharmacist before adding fish oil supplements.
3. Blood Pressure Medicines
Fish oil may support healthy circulation as part of a balanced lifestyle. However, people taking blood pressure medication should speak with a healthcare professional before using fish oil supplements regularly.
This is especially important for adults with long-term health conditions or those taking multiple medicines.
General Safety Tip
If you are taking any long-term medication, do not combine it with fish oil without professional advice. Leave at least a 2-hour gap between supplements and medicines unless your doctor or pharmacist gives different instructions.
Can Fish Oil Be Taken with Vitamin B Complex?
Yes. Fish oil can generally be taken with Vitamin B complex.
Fish oil is a fat-based supplement, while Vitamin B complex is water-soluble. They are absorbed differently and do not usually interfere with each other.
A simple routine may be:
- Fish oil: with meals or after meals
- Vitamin B complex: with or after meals, depending on personal comfort
For children, follow the recommended serving size on the product label.
Can Fish Oil Be Taken with Vitamin C?
Yes. Fish oil can generally be taken with Vitamin C.
Vitamin C is water-soluble and can be taken as part of a daily nutrition routine. For children with busy school schedules or selective eating habits, parents may choose a combination of supplements to complement a balanced diet.
When Is the Best Time to Take Fish Oil?
Fish oil is best taken with meals or after meals.
Taking fish oil with food may help:
- Improve absorption
- Reduce stomach discomfort
- Reduce fishy burps
- Make it easier to remember as part of a daily routine
There is no strict rule that fish oil must be taken in the morning or at night. The most important point is consistency.
Parents may choose the timing that best fits the child’s daily routine, such as after breakfast, lunch or dinner.
Who Should Be Careful When Taking Fish Oil?
Fish oil is suitable for many people, but some groups should be more careful.
1. People with Fish or Seafood Allergies
Fish oil is usually extracted from fish. Even though it is purified, people with fish or seafood allergies should be cautious.
If your child has a known fish or seafood allergy, speak with a doctor before giving fish oil. Algae-based DHA may be considered as an alternative.
2. Vegetarians or Vegans
Fish oil comes from animal sources, so it is not suitable for vegetarian or vegan diets.
Plant-based Omega-3 sources include:
- Algae oil
- Flaxseed oil
- Walnuts
- Chia seeds
However, plant-based Omega-3 sources may have different forms and conversion rates in the body.
3. Pregnant Women
Pregnant women should not take high-dose fish oil without medical advice, especially during the later stages of pregnancy.
If Omega-3 supplementation is needed during pregnancy, it is best to follow a doctor’s recommendation and choose a formula suitable for pregnancy.
4. Babies Under 6 Months Old
Babies under 6 months old should not be given fish oil supplements unless advised by a doctor.
At this stage, nutrition usually comes from breast milk or infant formula.
5. People Preparing for Surgery
People who are going for surgery should tell their doctor about all supplements they are taking, including fish oil.
Doctors may advise stopping certain supplements before surgery, depending on the person’s condition and the type of procedure.
6. People Taking Certain Medicines
People taking blood-thinning medicines, blood pressure medicines or NSAIDs should consult a doctor or pharmacist before taking fish oil.
This is especially important for adults with chronic health conditions or children who are taking medication.
Omega-3 Daily Intake: General Guidance
Omega-3 needs may vary depending on age, diet and health condition. Children who rarely eat fish may have lower Omega-3 intake from daily meals.
General international guidance commonly refers to EPA and DHA intake for children in the range of around 100 mg to 250 mg per day, depending on age. Older children and adults may require different amounts.
Parents should always check the serving size on the supplement label and avoid giving more than the recommended amount.
For children with special health conditions, allergies or medication use, consult a doctor, pharmacist or nutritionist before starting any supplement.

Fish Oil FAQ
Can fish oil be taken with multivitamins?
Yes. Fish oil can generally be taken with multivitamins.
Fat-soluble vitamins such as Vitamins A, D, E and K are usually better absorbed with dietary fat, while water-soluble vitamins such as Vitamin B complex and Vitamin C can also be taken as part of a daily routine.
If the multivitamin already contains Omega-3 or high levels of certain nutrients, check the label to avoid taking too much.
Can fish oil be taken with lutein?
Yes. Fish oil and lutein can generally be taken together.
Lutein is a fat-soluble nutrient, so taking it with a meal that contains fat may support absorption. Fish oil can be taken with meals as part of the same routine.
Can fish oil be taken with probiotics?
Yes, but they are often taken at different times.
Fish oil is best taken with meals or after meals, while probiotics are often taken before meals or according to the product label.
For children, always follow the instructions on each product.

Fish oil can be taken daily if it is suitable for the person and used according to the recommended serving size.
For children, parents should choose a product designed for kids and follow the label instructions.
Should fish oil be taken before or after meals?
Fish oil is usually better taken with meals or after meals.
This helps improve comfort and may reduce fishy burps or stomach discomfort.
Can adults take children’s fish oil?
Adults can usually take children’s fish oil, but the serving size may not match adult nutritional needs.
Adults who want to supplement Omega-3 should choose a product and dosage suitable for their age, diet and health condition.
