Core Prenatal+

Most prenatal vitamins are built to a minimum standard. Core Prenatal+ is built to an optimal one.

Formulated by Rhian Stephenson — nutritionist, naturopath and founder of Artah — this is a next-generation prenatal designed for the first trimester and for women preparing for pregnancy. Every ingredient is chosen for a reason, dosed to actually work, and third-party tested so you know exactly what you're getting.

No synthetic fillers. No questionable additives. Just the nutrients your body genuinely needs right now, in the forms it can actually use.

Two capsules daily, with food. For best results, start as early as possible — ideally before conception or as soon as you know you're pregnant.

Why it's different

Active folate, not folic acid Core Prenatal+ contains 500mcg of 5-MTHF — the biologically active form of folate your cells can use directly. Unlike standard folic acid, which requires multiple conversion steps, 5-MTHF is immediately available regardless of your genetic makeup. Up to 40% of women carry a variation that reduces their ability to convert synthetic folic acid efficiently. This formula removes that variable entirely.

Formulated for the first trimester specifically The first 12 weeks are when neural tube development, early organ formation and foundational cellular growth are happening at pace. Core Prenatal+ delivers the nutrients that matter most in this window — folate, Vitamin D, Vitamin B12, zinc, iodine and more — at dosages that reflect current nutritional science, not decade-old RDA targets.

No calcium, and here's why Calcium requirements don't increase during pregnancy — your body adapts to absorb it more efficiently. Artah deliberately excludes it from this formula rather than adding it as a box-ticking exercise. That decision reflects the rigour behind every ingredient choice.

100% natural, independently tested Free from gluten, dairy, soy, eggs, nuts and GMOs. No synthetic preservatives or chemical sweeteners. Third-party tested by accredited labs for potency and purity — what's on the label is what's in the jar.
