Carson Meyer Instagram – 1. Iron • Although an iron rich diet is important in pregnancy Synthetic Iron can wreak havoc on the digestive system causing constipation, nausea and indigestion. Excess iron can lead to oxidative stress which is why I believe it should be addressed on an individual bases and always through diet first. 2. Artificial Coloring • Believe it or not some prenatal vitamins contain dyes that are banned in other countries and linked to complications such as cancer and ADHD. Steer clear or any prenatal with synthetic dyes. 3. Heavy Metals • Look for a prenatal that is 3rd party tested for heavy metals such as lead which have been found in a number of prenatal vitamins on the market 4. Folic Acid • Folate is an important nutrient to promote a healthy fetal development especially in the first trimester. However, folic acid, the synthetic form of folate or methyl-folate does not covert effectively. Choose a prenatal that contains methylated folate instead of folic acid to assure its proper function. 5. Hydrogenated Oils • Industrial seed oils are highly processed and cause inflammation in the body even in small amounts.
