Is it a must to refrigerate liquid fish oil?

Hi,

Welcome to icliniq.com

Thanks for trusting us about your wife and baby health care. I have gone through your history and understood your concerns.

It is true that liquid fish oil should always be put in refrigerator after opening the bottle because it gets oxidized very soon on room temperature and become rancid and have ill health effects. As your wife is in her second trimester when she starts taking it, baby may not be affected in such a short period of time because organogenesis is completed in first trimester. It may get rancid immediately after exposure to sunlight. One health issue is that its efficacy and potency gets decreased. It will increase the plaque formation in vessel but same is not applying on fetus. As your wife is in 22nd weeks of pregnancy, it is better to get a second level ultrasound test to rule out any ill effect of rancid fish oil on fetus because it may affect neurons and brain development of fetus.

You are most welcome.

Yes, the easy way to see whether it is rancid or not is to smell the oil. If fishy smell is there then it is rancid otherwise not. If not rancid then health hazards are not there, but you should not use it. Second level ultrasound is ultrasound testing in which a radiologist sees each and every minute detail about fetus.
