Is Krill Oil Supplement Safe?


Dear Nutritionist,
I am in my 17th week of pregnancy and I have a couple of questions about the supplements I am taking.

I see a nutritionist who prescribed Krill Oil for me to take during the pregnancy. He said it would be very good for the brain development of the baby. Everything I have read about it sounds positive, I would just like to have a second opinion if you don't mind.

The Krill Oil is manufactured by Designs for Health, listed in it per serving are:

  1. Total Fat .95g  Saturated Fat .3g
  2. Cholesterol 15mg
  3. Sodium 5mg
  4. Vitamin A 100IU
  5. Choline (as phosphatidylcholine) 73mg
  6. Phospholipids 400mg
  7. Omega-3 fatty acids, total 300mg  docosahexaenoic acid (DHA) 90mg  eicosapentaenoic acid (EPA) 150mg
  8. Omega-6 fatty acids, total 20mg
  9. Astaxanthin 1.5mg

I am also taking Precare prenatal vitamin which doesn't have any Vitamin A, but I am concerned about the Vitamin A in the Krill Oil, do you think this is a problem?

My nutritionist also recommended me to take an acidopholus supplement, I took it for 2 days & forgot to refrigerate it. Do you think this is dangerous for the baby? I have stopped taking it after I read on the side "if pregnant consult physician before taking". I'm worried after reading that statement that it could have done something to the baby.

Thank you in advance,


Hello Jennifer,
You should always consult with your OB/GYN or other pregnancy healthcare provider before taking any supplement during pregnancy or breastfeeding. Since I do not have knowledge of your present or past medical history it would be difficult for me to give my opinion on any specific supplement you are taking.

I can tell you that pregnant women should NOT get more than 10,000 IU of vitamin A daily and the supplement you listed only had 100 IU. Again, if you have any question about taking this supplement or the acidopholus supplement than you should speak with your physician first!
