Optimal Prenatal 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.

Optimal Prenatal 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.

Energize and feeling better!

I tried these before I was pregnant, when we were TTC. I prefer to swallow pills than chew them but these have such great ingredients I thought I would be fine. 2 weeks in to taking them, they started making me gag. Chalky orange flavor, and two pretty large pills daily can get old. Now I am 8 weeks pregnant and have switched back to Seeking Health, and just wished I stayed with them the whole time. I am no longer having morning sickness (which the other prenatal was giving me ALL DAY), I have more energy than I have had in weeks, and I am feeling more like myself. And still have 4 weeks left of the first trimester! So I keep chewing these pills daily, even when I do not personally like the taste. For the awesome benefits I get from them! Highly recommend them, really helped me feel better and I know my baby is getting everything it needs.

I Love This Supplement And I'm Not Pregnant

I'm going to admit to Dr. Lynch that I am taking prenatal vitamins and I am not pregnant and have no plans to be so. I appreciate the milk thistle, the CoQ10, the extra folate in the proper form. I mistakenly got the prenatal capsules the first time but when I looked at the supplement facts I could see no reason why a 65-year-old woman couldn't take these as well. I really get tired of capsules though and so I then ordered the chewables and that is the answer for me.

These taste fine (they aren't candy, so fine is good) and chewing two a day is a whole lot easier than swallowing 8 capsules. I am not on any blood thinning medications, so the Vitamin K is okay for me and is useful for utilizing Vitamin D. If I am travelling being able to take one bottle along to get a wide range of supplementation is wonderful, so it seems like a win/win to me.

I bought this prenatal for the ease in chewing 2 after breakfast each morning and being done for the day with supplements. They taste great, orangey like a Vitamin C chew almost. No issues with chewing them and nausea. Overall I actually feel pretty good for being in the first trimester! Highly recommend!!
