  • High-strength pregnancy support in one daily capsule. 4000IU vitamin D3, 600µg active 5-MTHF folate, iodine, and choline — the maternal-nutrition essentials, formulated with UK-registered nutritionists.

Description

A four-month, once-a-day pregnancy support formula. High-strength vitamin D3, active 5-MTHF folate, iodine, and choline in a single vegetable capsule, formulated with UK-registered nutritionists.

What does it do?

  • Pregnancy support. Folate contributes to maternal tissue growth during pregnancy.
  • Mother and baby nutrition. Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus, and to the maintenance of normal bones and teeth.
  • Cell division. Vitamin D has a role in the process of cell division, and folate contributes to normal blood formation.
  • Thyroid and cognition. Iodine contributes to normal thyroid function and normal cognitive function.
  • Liver and homocysteine. Choline contributes to normal homocysteine metabolism and the maintenance of normal liver function.

Why this formulation

Vitamin D3 in its cholecalciferol form and folate as 5-MTHF — the biologically active forms your body uses directly. Iodine at the full 150µg reference intake, and choline in a bioavailable L-Bitartrate form.

What’s NOT in it

  • No synthetic folic acid (only active 5-MTHF folate)
  • No binders
  • No magnesium stearate
  • No titanium dioxide
  • No artificial colours or sweeteners

Directions

Take 1 capsule per day, ideally with meals, or as directed by a healthcare professional. Do not take with other supplements containing vitamin D, as this product provides the daily upper limit for adults.

120 vegetable capsules per bottle. One capsule per day. Four-month supply.

Advice

Food supplements should not replace a varied, balanced diet and healthy lifestyle. Do not exceed the recommended daily intake. If you are under medical supervision or taking medication, consult your healthcare professional before use.

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

FOUNDER STORY

Bio Mirco

BioMirco was founded by Jay and Natasha Necati, a husband-and-wife team, after more than a decade of infertility, IVF and pregnancy loss. Natasha, a fertility advocate who has spoken about pregnancy loss in national media and Jay set out to build the preconception formula they wished they'd had: active-form nutrients, a serious dose of CoQ10, and nothing they wouldn't take themselves.

THE SCIENCE

Why it works

What is High Strength Vitamin D3 4000IU?

Pregnancy places extra demand on several key nutrients. Folate is critical from the earliest weeks but many prenatal supplements use synthetic folic acid, which needs converting by an enzyme (MTHFR) that a large proportion of women have reduced activity of. This formula uses 5-MTHF, the already-active form. Vitamin D3 is provided at the EFSA upper safe limit (4000IU / 100µg) — appropriate for the UK's shorter daylight hours and to compensate for typical dietary shortfalls. Iodine is provided at 100% of reference intake, important for thyroid function which underpins foetal cognitive development. Choline is added for its role in liver and homocysteine metabolism.

USAGE

How to take it

Take 1 capsule per day, ideally with a meal containing some fat. Do not take alongside other supplements containing vitamin D, as this product provides the daily upper limit for adults. Can be taken throughout pregnancy and continued while breastfeeding. If you are under medical supervision, consult your healthcare professional before starting.

QUESTIONS

Frequently asked

Is 4000IU vitamin D3 safe during pregnancy?
Yes. The EFSA tolerable upper limit for adults, including pregnant women, is 4000IU (100µg) per day. This product provides exactly that limit, which is why you should not take it alongside other supplements containing vitamin D.

Can I take it while breastfeeding?
Yes. The nutrients in this formula are safe and beneficial during breastfeeding at the doses provided. As always, consult your healthcare professional if you have specific concerns.

When should I start taking it?
From the moment you know you are pregnant (or planning to conceive). Folate and vitamin D are both important from the earliest weeks of pregnancy.

Do I need to take it with food?
Yes, ideally with a meal containing some fat, vitamin D is fat-soluble and absorption is significantly better with dietary fat.

RESEARCH NOTE

Vitamin D and folate are both foundational to maternal nutrition. Folate contributes to maternal tissue growth during pregnancy; vitamin D contributes to normal absorption of calcium and phosphorus and to normal cell division. Iodine contributes to normal thyroid function and normal cognitive function. Choline contributes to normal homocysteine metabolism. All claims here are drawn from the GB Nutrition and Health Claims Register.

Working well

Very happy with these vitamins. They have no strange taste, are easy to swallow and I am already noticing an improvement in how I feel. My skin feels better and for the amount they are great value.

Good value

It's a pretty good D3 supplement, but only as a value option. The left out K2 make it less preferable for everyday users, but those with the mentioned medical conditions will definitely apprechiate it. But despite this, it's still a good option for ongoing Vitamin D supplementation.For this price it's an amazing deal.

So far so good

It was advised by a friend that I try using a D vitamin supplement to aid in improving energy levels during the winter months. Now that winter is upon us, I ordered these ones.These capsules are an excellent size - they are nice and small compared to mny others that I have tried so they are very easy to swallow (I find that larger ones can be more difficult to get down). I cant speak to the combination of different minerals as I know nothing of the specifics, so am taking it on trust that contain the requisute amounts.Theres 4 months supply for £10 which seems like a reasonable price.
