Purolabs Pregnancy Complex Review 2026: Review
Checks out. — Legitimate

"Active methylfolate better than folic acid for pregnancy"
Women with MTHFR variants (10-15% of population) cannot convert folic acid. L-5-MTHF bypasses this. NHS acknowledges the issue.
PubMed: Greenberg et al., Nutrients 2011 — MTHFR and folate metabolism -
"Iron bisglycinate is gentler than standard iron"
Ferrous bisglycinate caused significantly fewer GI side effects than ferrous sulfate in clinical trials while maintaining absorption.
PubMed: Szarfarc et al., Arch Latinoam Nutr 2001 — iron bisglycinate vs sulfate -
"No fillers or bulking agents"
Brown Rice Flour appears in the ingredient list — a standard filler. This directly contradicts the marketing claim.

"Sodium Tetraborate Anhydrous safety in pregnancy"
Borax is restricted in EU food and cosmetic products. No pregnancy safety data exists. Safer boron forms are available.

Consumer advice
This is a genuinely good prenatal supplement. The use of L-5-methyltetrahydrofolate (active folate) is a real advantage — roughly 10-15% of women have MTHFR gene variants that reduce their ability to convert synthetic folic acid, making the active form a smarter choice. Iron bisglycinate is clinically shown to cause less constipation and nausea than standard ferrous sulfate. If budget is a concern, a basic pharmacy prenatal (Pregnacare, Seven Seas) will still cover the NHS-recommended minimums. But if you can afford the premium, the ingredient quality here is legitimately better. Always consult your midwife or GP before starting any prenatal supplement, especially if you take other medications.
