Just follow your OB-Gyne as not many know that fish oil supplementation is a national plan by some country   I can't find the source.
Just make sure that the fish oil doesn't contain mercury, rosemary extract (Carlson is perfectly fine. If you are buying Nordic, avoid the ultimate version, get the prenatal version which will not have rosemary extract)

My opinion? They are worthless. Dosage is too low to do good. For multivitamin, I recommend taking spirulina + chlorella. Why? Both of them are highly dense nutritious food. More nutrient dense than anything. An entire community in Africa at Lake Chad survive on dried spirulina cakes and they are not undernourish like the rest of the Africans.
For CoQ10, one should buy ubiquinone produce by Kaneka 

For me and my family,
Multivitamin : Nutrex Hawaian Spirulina + Yaeyama chlorella powder 1tsp each (much more cost economical than tablets)
Fish Oil : Nordic/Carlson
Antioxidant : Healthy Origins Astaxanthin
Parents : Healthy Origins CoQ10 Ubiquinone 100mg (to counter the effects of statins)

If you really want me to recommend multivitamin,
Pure essence master multivitamin 240 tablets
Life extension mix tablets 315 tablets

Of course one does not need to take the full dosage. Hence the above 2 is value for money.
