vitamin supplements while breastfeeding

[mommac2006]

I'm trying to find a way to help boost my immune system and the babies if that is even possible besides breastfeeding. Is D-3 safe to take while breastfeeding?

If not, please give me some safe recommendations because I really need to start on something with having a MIL who works at a headstart and a 3 year old son will soon be starting classes with his homeschooling group.

I take a mega-dose multivitimin from Usana. It contains 300 IU of D3. When taken as directed, I take that dose twice a day. I've been taking it for about 6 years, through two pregnancies and breastfeeding long term. These vitamins got the ok from my doctor to take instead of the prenatals.

I do think that they help boost immunity for me, and as a benefit, I "lost" my allergies after I started them, allergies I'd had for almost 10 years at that point.
