Who stands behind the formula
These brands put a professional behind the product. Needed describes practitioner distribution as part of its model and prints each prenatal dose. FullWell was founded by dietitian Ayla Barmmer, MS, RD, and says a fertility dietitian designed its prenatal. Theralogix sells a clinical line and says NSF International certifies TheraNatal OvaVite. These statements come from the brands' own pages. None of that makes the product a prescription, so your own clinician still decides what fits.
What to check before you buy
What to look for
Authorship on the brand page is not the same as a prescription.
Common mismatch
Choosing a product for its credentials without checking that the label fits your stage.
If a clinic is involved
The clinic's list wins. Take the label to the appointment so the clinician can see what is in the routine.
What the scores rate
Scores rate the label and the published price, not your chance of conceiving.

Common questions about practitioner and dietitian lines
What does dietitian-designed mean on a label?
It means the brand says a dietitian chose the nutrients and amounts. FullWell says a fertility dietitian designed its prenatal, and it publishes the reasoning behind the formula. It does not mean a dietitian has reviewed your own needs.
Are these products for trying or for pregnancy?
Needed's and FullWell's main products are prenatals, so they fit pregnancy and the months before it. Theralogix's TheraNatal OvaVite is sold for the preconception stage.
Do these brands sell anything for men?
FullWell sells a men's multi beside its women's prenatal, and Theralogix's men's product is ConceptionXR Reproductive Health, $66 for a 90-day supply. Needed does not sell a men's fertility formula.
How much do they cost?
Needed lists its Prenatal Multivitamin at $42.99 a month, or from $34.39 on subscription. FullWell's Women's Prenatal Multivitamin starts at $42.45. Theralogix lists TheraNatal OvaVite at $124 for a 13-week supply. These are the brands' published prices from October 2026, and they can change.
