Now that I've "come out" to the world about being pregnant it's time to share all the knowledge I've been acquiring throughout the past 2 1/2 months! (Facebook & technology has changed the world in so many ways!! so easy, with just a click, my world knew!)
In my opinion, Iron is absolutely the MOST important supplement/nutrient to get into your body when you're pregnant.
This metal carries oxygen from the lungs to every cell in the body. Its other big role is to make blood. Blood volume increases by 50% during pregnancy. Blood feeds the placenta and uterine lining. Without large members of oxygen-rich red blood cells, your baby won't grow.
For a straight hit of iron, eating red meat or liver is a sure bet. Clams, chicken liver, duck and oysters are excellent sources. (if you're vegan or vegetarian, look below for an awesome option) Fish, poultry, spinach, dried apricots and unsulphered or black-strap molasses are decent sources. Grains and dairy foods are not.
It's also wise to eat iron-friendly foods, including fresh produce for folate and vitamin C, banans for B5 and any meat, milk or eggs for B12.
I highly recommended Floradix, a liquid supplement with organic iron in an absorbable form (ferrous gluconate) instead of inorganic iron, which can cause constipation. I take this almost every day. I love the way it tastes and I instantly have more energy after consuming it. I don't eat red meat and haven't for almost 10 years, so it's vital to get it from a supplement source. I've taken it for years, (I'm slightly anemic) usually every day when I'm on my period and here and there when I'm not.
Another option is taking ground liver capsules. If you're not anemic, don't take iron. The body doesn't excrete iron easily, and too much can be toxic.
