Overview
Two active forms of folate and an easy-on-the-stomach iron called picolinate do the heavy work in this Thorne prenatal. It is a complete multivitamin for pregnancy and breastfeeding, in capsules.
Active folate suits women who do not convert folic acid well, and iron picolinate is chosen to avoid constipation, a common prenatal complaint. It covers nursing as well as pregnancy. The listing leaves out capsule count per day and nutrient amounts.
Who it's for
Women who are pregnant or breastfeeding and get stomach upset from standard prenatals get a gentler formula. Those who want one tiny tablet a day may find capsule dosing less convenient.
Pros and cons
- Two active folate forms
- Iron picolinate is non-constipating
- Covers pregnancy and nursing
- Daily capsule count not listed
- Nutrient amounts not shown
- Capsules only, no chewable
Performance notes
Active folate skips the conversion step that some women handle poorly, so the body can use it directly. Iron bound to picolinate absorbs well with less gut irritation than common iron salts. Taking capsules with food can further ease nausea.
