7 high-quality ingredients

Using seven essential ingredients, our men's preconception vitamins are formulated to help take out the guesswork in determining which nutrients can be taken on your journey to pregnancy. The Male Prenatal Daily Packets were carefully developed using peer-reviewed studies that reflect the latest research in male fertility, nutrient deficiencies, and pregnancy outcomes. The formula development of these prenatals for men was led by a Harvard-trained urologist and a registered dietitian-nutritionist. Not only were the specific ingredients selected for the male prenatal vitamin based on strength of evidence, but the dosages of each ingredient are also evidence based to ensure adequate impact on sperm quality and health.

Urologist and Male Fertility Expert
"When combined with a healthy diet and lifestyle, the ingredients in our extensively researched and scientifically formulated Male Prenatal Daily Packets have been shown to improve semen volume and sperm quality."

We do our homework. See the research behind Male Prenatal Daily Packets.

The Male Prenatal Daily Packets were thoughtfully formulated by experts.

Our prenatal vitamins for me ndaily packets were carefully developed using peer-reviewed studies that reflect the latest research in male fertility. The formula development was led by Dr. Andrew Sun, a Harvard-trained urologist and expert in the field of male fertility and Lauren Manaker, RD, an award-winning registered dietitian-nutritionist and specialist in male fertility.

We use high bioavailability, biologically identical ingredients.

Our vitamins are formulated with premium, high bioavailability ingredients for maximum efficacy and potency.

Dosage matters, and we use evidence to determine optimal dosages of each ingredient.

Not only were the specific ingredients selected based on strength of evidence, but the quantities of each ingredient are also evidence-based to ensure adequate impact.

We are committed to manufacturing excellence. Every batch of vitamins is tested for product integrity.

All of our vitamins are made in an FDA Registered and Inspected Facility, which meets or exceeds FDA 12 CFR 111 guidelines, and is also GMP Certified. Certificates of analysis are reported for every batch of manufactured prenatal vitamins to ensure final product integrity and quality. Our vitamins are free of artificial and synthetic dyes, and all allergens are disclosed on our label. Additionally, our vitamins are manufactured under strict procedures to ensure there is no cross-contamination during manufacturing and storage.

It matters where your omega-3s are coming from. Ours is from the best source—the ocean.

Omega-3s are a class of long-chain polyunsaturated fatty acids (FA) that are integral to the formation of neuronal cell membranes in the brain and retina. The human body cannot synthesize most omega-3s, and instead, must rely on dietary sources. Not all omega-3 FAs are created equally. Depending on the source of omega-3 FAs in a supplement, the ratio of DHA, EPA, and ALA will be different. Omega-3s sourced from algae, like ours, are highly enriched in DHA. Omega-3s from vegan sources, such as flaxseed oil, chia seed oil or walnut oil, do not contain DHA. Instead, they predominantly contain ALA, which isn’t useful during pregnancy. Always read the label, and check the DHA content of your omega-3 supplement.

Our vegan omega DHA from margin algae undergoes an environmentally-friendly, chemical-free extraction process.

Our vegan and 100% natural omega DHA is derived from a strain of wild-sourced marine algae, initially discovered and isolated from the pristine coastal waters of the Bay of Fundy, Nova Scotia, Canada. The DHA oil undergoes an environmentally-friendly, chemical-free extraction process. Each batch is then tested for heavy metals and allergens.

Formulated to support fertility treatment outcomes.

Antioxidants have been shown to improve live birth rate for couples undergoing fertility treatment. A 2019 Cochrane systematic review concluded that antioxidant supplementation in subfertile men improves live birth, clinical pregnancy rate, and sperm DNA fragmentation.

Unlike other like-supplements, we don't include folic acid or zinc in our men’s prenatal formula. We intentionally chose to exclude these two ingredients based on the outcomes of a well-designed study published in JAMA. In this randomized clinical trial of 2,370 couples, the use of folic acid and zinc supplementation by male partners, compared with placebo, did not significantly improve live birth rates or semen quality. 

Medical research is a constantly evolving field. As new research and clinical experience broaden our knowledge, changes in our formula may become apparent or appropriate.

Formulated with ingredients associated with improved semen quality.

  • The antioxidants in our formula have been associated with improving many sperm health parameters: motility, count, concentration, and morphology.
  • Vitamin E plays a vital role in protecting cell membranes from oxidative damage trapping and scavenging free radicals within cellular membranes. Studies show that vitamin E supplementation significantly improves sperm motility.
  • A meta analysis showed omega-3 supplements might improve semen quality parameters in infertile men and men from couples seeking fertility treatment.

Made with ingredients shown to protect against oxidative damage.

Oxidative stress is known to be an important factor that causes male infertility by damaging sperm DNA, which can affect natural conception and embryo development.

Antioxidants play an important role in protecting semen from oxidative stress and may improve sperm health. A meta-analysis of 32 studies published between 2000 and 2013 related to male infertility and antioxidants found vitamin E, vitamin C, selenium, and CoQ10 to be effective in improving semen parameters.

May help with erectile dysfunction (ED).

A significant proportion of erectile dysfunction (ED) patients have a vitamin D deficiency. Research shows that vitamin D supplementation may help delay the onset of ED—and may even restore normal sexual function to some men when coupled with positive lifestyle changes. Additionally, one study suggests vitamin C and vitamin E support the biochemical pathways leading to nitric oxide (NO) release, improving erectile function.

Non GMO, but that doesn’t really matter.

Along with 88% of polled scientists, Natalist believes that the majority of genetically modified (GM) foods are safe. That said, we also believe that bioengineered ingredients should be clearly labeled so that consumers can make an informed purchase decision. Transparency is essential in building trust between brands and consumers. Our products clearly state if they do or do not contain genetically modified organisms (GMOs).

tart taking Male Prenatal Daily Packets at least three months before you plan to conceive to allow the nutrients to fully support sperm production and health.
