Key Benefits and Actions*

  • Support healthy methylation processes*
  • Includes active B6 and milk thistle extract to support digestive comfort*
  • Includes active folates to help support healthy fetal development*
  • Sustain immune health*

Prenatal Essentials Chewable offers a specialized prenatal formula designed to help meet the high nutritional needs of women who are pregnant or preparing for pregnancy – or anyone looking for a well-rounded multivitamin in an easy chewable format. This formula contains both folinic acid and L-5-MTHF, the most biologically available forms of folate, which are essential during pregnancy to support healthy brain development. L-5-MTHF works in conjunction with chelated minerals and coenzyme forms of B vitamins to support cardiovascular, neurologic, and immune health and normal cell growth. This formula is iron-free for maximal versatility.

Prenatal Essentials Chewable also contains two active coenzyme forms of vitamin B12: methylcobalamin and adenosylcobalamin, which may help support healthy fetal development, energy metabolism and methylation. The well-balanced vitamin B complex is complete with active forms of riboflavin and B6 to support healthy growth and development.*

Vitamin A is included in two forms: beta-carotene and retinyl palmitate, to help support those who have trouble converting “provitamin A” compounds (such as beta-carotene) into the active retinyl/retinol forms. Vitamin C and coenzyme Q10 provide antioxidant support, supporting a healthy immune system and cellular integrity. Trace minerals are included in their chelated forms, as amino acid-chelated minerals are typically well-absorbed and may be more easily tolerated than alternative supplemental forms. Betaine Anhydrous (TMG) is also added for additional methylation support.*

For the comprehensive prenatal nutrient support with additional herbs and amino acids, consider our Optimal Prenatal Capsules or our great-tasting Optimal Prenatal Protein Powder – available in creamy vanilla or chocolate.

7. Is Prenatal Essentials Chewable vegetarian/vegan?

Wonderful for nausea

I switch to these from the optimal prenatal when I started being unable to keep those ones down. The chewable was much easier to take and keep down and tasted pretty good.

Don’t like the new flavor

I gave 5 stars before but I’m so bummed that the flavor changed. I can’t eat these anymore. They seem way too sweet now. Please consider tweaking it again.

The only prenatal that works for me

I’m currently 16 weeks and have been through at least five prenatal vitamin brands. I’m super picky about what ingredients are in my vitamins, and there aren’t many brands out there that meet my expectations. The few brands I did find that were natural all made me sick to my stomach. A friend recommended this brand. I had never heard of Seeking Health before then, and I’ll never go back to another brand. I was hesitant with it being a chewable, but I can keep it down and it settles with me well. The only negative is I have to separately add magnesium and iron, because it lacks those two nutrients.
