Are women trying to conceive missing key nutrients?

Federal health data suggests many are. A 2026 analysis of national nutrition survey data found women reporting infertility had significantly lower intakes of vitamin A, E, K, and lutein and zeaxanthin than women without infertility, with more than half of women experiencing infertility falling below minimum requirements for vitamins A, C, E, magnesium, and potassium.† This is not proof that a nutrient gap causes infertility, but it is a real signal that fertility-support conversations often skip basic nutrient status.

What the national data actually found

A cross-sectional analysis using NHANES data from 2013 to 2020, covering nearly 3,900 women aged 18 to 44, compared nutrient intake between women who reported infertility and those who did not. Researchers found women reporting infertility had significantly lower intakes of vitamin A, vitamin E, vitamin K, and lutein and zeaxanthin, along with lower selenium, vitamin C, and calcium intake compared with women who did not report infertility.

More strikingly, the same analysis found that more than half of women with infertility fell below the estimated average requirement for vitamins A, C, and E, along with magnesium and potassium, with the gap most pronounced among women aged 35 to 44. The researchers were careful to note this is a cross-sectional, observational study. It cannot establish that these nutrient gaps caused the infertility, only that the two are associated in this national dataset.

What this does and doesn't mean

It's worth being direct about what the research does not claim. A Cochrane systematic review of antioxidant supplements, including vitamins C and E, in women undergoing fertility treatment found no clear evidence that antioxidant supplementation improved outcomes for women undergoing assisted reproductive procedures. So this is not a case where "add nutrient X" is proven to reverse infertility. It is a case where population-level nutrient status among women experiencing infertility looks meaningfully different from women who are not, which is a real and underdiscussed gap in fertility conversations that lean heavily on supplement listicles.

The American Society for Reproductive Medicine's prepregnancy counseling guidance recommends that any encounter with a patient of reproductive potential include screening for whether diet and supplement use are meeting recommended intakes for nutrients like calcium, iron, vitamin A, vitamin B12, and vitamin D, reinforcing that this is a genuine, recognized part of preconception care, not a wellness-industry talking point.

Covering the specific nutrients where this gap showed up

Total Prenatal, designed to support preconception through breastfeeding, is formulated with 22 vitamins and minerals, including vitamin D3, vitamin B6, and vitamin B12, aimed at covering exactly the kind of broad micronutrient foundation the research above highlights as commonly falling short.† Myo Chiro 40:1, a fertility-focused hormone support formula, supports healthy hormone signaling, ovarian health, and menstrual cycle regularity through a clinically studied 40:1 ratio of Myo-Inositol to D-Chiro-Inositol.†

Frequently asked questions

Do women trying to conceive actually have lower nutrient intake?

National data shows women reporting infertility had significantly lower intakes of vitamin A, E, K, and lutein and zeaxanthin than women without infertility, with more than half falling below minimum requirements for vitamins A, C, E, magnesium, and potassium.

Does this mean a nutrient gap causes infertility?

No. The research is observational and cross-sectional, meaning it shows an association, not proof that nutrient gaps cause infertility.

Do antioxidant supplements improve fertility treatment outcomes?

A Cochrane review found no clear evidence that antioxidant supplementation improved outcomes for women undergoing assisted reproductive procedures, so this should not be read as a guaranteed fix.

Is nutrient screening part of standard preconception care?

Yes. Professional guidance from ASRM and ACOG recommends screening diet and supplement use against recommended intakes as part of routine prepregnancy counseling.

Can Total Prenatal and Myo Chiro 40:1 be used together while trying to conceive?

Many women pair a foundational prenatal multivitamin with a hormone-health-focused formula during the preconception window, though you should always consult your healthcare provider before starting any new supplement.†

Is Myo Chiro 40:1 safe once I'm pregnant?

No. Myo Chiro 40:1 is not intended for use during pregnancy. Always consult your healthcare provider before starting any new supplement, especially while breastfeeding.†
