1. People with allergies to fish, seafood or soy
These subjects should not use omega-3, because most fish oil products are extracted from these sources. Using it can cause allergic reactions, even anaphylactic shock.
2. People with severe kidney disease or are having dialysis also need to be careful
Some forms of omega-3 may contain high levels of phosphorus which is not suitable for kidney patients. In addition, if dosed too high (over 3g per day), omega-3 can cause unwanted effects such as increased risk of bleeding or fat metabolism disorder.
3. People who are taking anticoagulants or have a blood clotting disease
The reason is that omega-3 can thinning blood, increasing the risk of internal bleeding or prolonged bleeding.
4. Pregnant women, breastfeeding or children under 18 years old
This group should not arbitrarily use omega-3 without professional instructions. Studies are not strong enough to confirm the absolute safety of these subjects when using high doses for a long time.
5. People being treated with cyclosporine or drugs to regulate blood pressure
Those who are taking immunosuppressants such as cyclosporine or blood pressure medications should also be careful. Omega-3 can affect the effects of the drug, reduce the effectiveness of treatment or cause excessive low blood pressure.
If you are in one of the above groups, omega-3 use should be carefully advised by your doctor, especially when the purpose of use is related to supporting kidney function or detoxifying.
