Prenatal Supplement Comparison Chart

What's in popular prenatals vs. what you actually need

Not all prenatals are created equal. Most contain forms your body can't use efficiently, or leave out critical nutrients entirely. Use this chart to evaluate yours.

Key Nutrients: What to Look For

NutrientOptimal FormDaily NeedWatch Out For
FolateMethylfolate (5-MTHF)800 mcgFolic acid (synthetic, ~40% of people can't convert efficiently)
IronIron bisglycinate27 mgFerrous sulfate (causes constipation)
CholineCholine bitartrate or CDP-choline450 mgMost prenatals contain 0 mg
DHATriglyceride-form fish oil or algae DHA300-500 mgEthyl ester form (less bioavailable)
Vitamin DD3 (cholecalciferol)4,000 IUD2 (ergocalciferol — less effective); most prenatals have only 400-600 IU
IodinePotassium iodide220 mcgMissing entirely from many prenatals
MagnesiumGlycinate or malate350 mgOxide (poorly absorbed; only 4% bioavailability)
B12Methylcobalamin2.6 mcgCyanocobalamin (requires conversion)
Vitamin K2MK-7100 mcgUsually absent; needed for calcium metabolism
ZincZinc picolinate or bisglycinate11 mgZinc oxide (poor absorption)

Your Prenatal Evaluation Checklist

Contains methylfolate (NOT folic acid)
Contains choline (most don't — you'll need a separate supplement)
Contains DHA/EPA or paired with a separate omega-3
Vitamin D is 2,000+ IU (not just 400)
Contains iodine (150-220 mcg)
Iron is bisglycinate (gentler on stomach)
Contains magnesium in absorbable form
B vitamins are in methylated forms
Third-party tested for purity (NSF, USP, ConsumerLab)
Free of unnecessary fillers, dyes, and titanium dioxide

Important

If your prenatal is missing choline and DHA, supplement separately. These are the two most commonly underdosed nutrients in pregnancy, and they're critical for brain development.

Supplements You May Need Separately

Choline

450 mg/day (most prenatals have 0)

DHA/EPA

300-500 mg DHA (need fish oil or algae)

Vitamin D3

Additional 2,000-4,000 IU to reach optimal

Magnesium

200-400 mg glycinate (evening dose)

Probiotic

Multi-strain, 10+ billion CFU

Vitamin K2

100 mcg MK-7 (if not in prenatal)
