Hi Heartbeats, what I find is, according to the recommended daily intake for preggers, the DHA that dr Loh prescribes is enough. What I've done since the start of 3rd trimester is, I've up my DHA cos by then, dr Loh's dosage became minimal requirement, as the DHA we need is highest in 3rd trimester but it's perfectly fine too to take same dosage fr Dr Loh's as we get DHA fr other food sources too
As for the multivitamins, dr Loh's seems fine just that I find that iron is slightly lacking (compared with recommended daily intake for preggers) so I try to take more red meat. Unfortunately, there is no protein in the multivitamins if I'm not wrong and since we need abt 50-70g daily, can consider eating more chicken, eggs, beans, etc. For me, since my appetite isn't too great, I'm taking an organic plant protein powder.
Iron and proteins are both very important components for healthy growth of our babies (amongst other things), so it's good to include them in our diet
Recently, zinc has been getting more focus for pregnancy health, RDI 11mg. I think dr Loh's multivitamins doesn't has much of zinc, so I take walnuts daily since preg.
Sorry for the info overload. Hope this helps
