Almost everyone starts in the same place. You decide you want to get pregnant, you buy a prenatal vitamin, and you assume the nutritional side is handled. It is a reasonable assumption, and it is the one we spend the most time correcting.
A prenatal vitamin and preconception fertility support are two different jobs. They overlap, but they were designed with different readers in mind, and the gap between them is where most people lose several useful months.
A conventional prenatal is a broad insurance policy for pregnancy. It aims to cover a wide list of nutrients at modest levels, with folate for neural tube support as the headline ingredient and iron and iodine usually alongside it. That formula is built for a woman who is already pregnant and needs adequate coverage across the board.
Preconception is a narrower problem. In the months before conception you are not insuring a pregnancy, you are working on the maturation of eggs and sperm, on methylation, and on filling the specific gaps a general multivitamin tends to skim over. Breadth stops being the priority. Form and dose start to matter more.
Most prenatals use synthetic folic acid, which the body has to convert before it can use it. A meaningful proportion of people convert it inefficiently, and anyone carrying an MTHFR variant may convert it less efficiently still. Active folate, listed as 5-MTHF, skips that conversion step entirely.
This is why Rejoova Core uses active 5-MTHF at 1000 mcg DFE rather than folic acid. It is a formulation decision rather than a marketing one, and the reasoning is laid out in full on the product page.
Choline supports neural tube closure, early brain development, placental function and liver health, and it is one of the most under-consumed nutrients in pregnancy. Adequate intake in pregnancy is set at 450 mg per day, with many clinicians arguing for closer to 550 mg. A large number of prenatals contain very little of it, and some contain none at all.
Rejoova Core provides 300 mg per serving, designed to close a meaningful part of that gap alongside a choline-rich diet. Paired with Rejoova Eggs, the two are formulated to cover the areas a prenatal is most likely to shortchange. What that pairing does not do is replace a fully quantified prenatal panel, and the honest version of that answer sits in the Rejoova FAQs. Iodine, B12 and iron are worth testing rather than assuming, because those are the nutrients where individual requirements vary most.
A prenatal and a fertility supplement are often treated as alternatives, which is a false choice. They act on different things. Folate and choline support methylation, cell division and early development, which matters from the moment of conception onward. Egg and sperm quality support acts earlier still, on the cells that have to meet in the first place. One prepares the pregnancy, the other prepares the conception.
That distinction is why most preconception protocols run both together rather than choosing between them, and why the egg health guides are worth reading alongside this section.
Nutrient repletion is not immediate. Eggs mature over roughly three months, sperm regenerate over a similar span, and folate and choline status build gradually rather than switching on. Starting three months before you begin trying is the standard clinical recommendation for that reason, not because three is a tidy number.
If you are earlier in the process than that, the preparing for pregnancy guides map out what belongs in each stage of the runway. For a combined protocol, the Corenatal Fertility Bundle brings the egg quality and prenatal foundation formulas together. None of this substitutes for personal medical guidance, and anything involving diagnosed conditions, medication interactions or an active treatment cycle belongs in a conversation with your own provider.
One of the most common questions I hear from patients is: "What supplements should I be taking?" My answer is always the same. It depends on where you are in your fertility journey and how your body is changing. Fertility support is not one-size-fits-all. What your body needs …Read More
