Your recommended DHA dosage is based on your current blood level. By testing your DHA with the free NurtureKit provided in month one of your subscription, we can suggest a dosage tailored to help maintain or improve your levels, supporting a healthy pregnancy.

If you choose not to take the blood test, both 600mg and 900mg of DHA are considered safe and appropriate during pregnancy. These doses are designed to safely support maternal DHA intake, although testing allows us to guide you more precisely based on your individual needs.

Clinical studies show that daily intakes of up to 1,000 mg of DHA are considered safe for pregnant and breastfeeding women, with no links to safety concerns - and women taking this higher dosage actually often reduced risks of certain complications and had fewer adverse effects.

Many guidelines suggest a minimum of 200–300 mg of DHA per day during pregnancy. However, clinical studies indicate that a daily intake of 600–1,000 mg can significantly reduce the risk of preterm birth. This means the 200–300 mg dose should be considered a baseline rather than an optimal target. Women with low dietary intake, low blood DHA levels, or higher risk of pregnancy complications may particularly benefit from taking 600–1,000 mg daily.

While exact targets vary slightly, most experts suggest aiming for a DHA level that supports optimal maternal and fetal health, which is generally >4–5% of total red blood cell fatty acids. Testing lets us see where you are and whether you need adjustments.

Daily intakes of up to 4,000 IU (100 µg) are generally safe in pregnancy.

While doses of 400iu (10ug) are often included in public guidelines, this is often inadequate for pregnancy, especially as deficiency is common. Therefore, studies show higher amounts of 2000 - 4000iu are safe and often needed to achieve sufficient blood levels, especially in women with deficiency.

Exceeding the safe intake of any nutrient is uncommon when using supplements as directed, but taking high doses or combining multiple different supplement products could risk going over upper limits and may cause side effects. Nurture’s recommendations are always within evidence-based safety limits. It’s always best to avoid stacking up supplements and always checking labels carefully

Guidelines recommend 400µg per day before and during early pregnancy.

If your blood test shows your levels are adequate, your dosage may be lower to maintain healthy levels, avoiding unnecessary supplementation.

NRV stands for Nutrient Reference Value. It shows how much of your daily recommended intake of a vitamin or mineral is provided by one daily dose of your supplement.

For example:

• 100% NRV means the supplement provides the full recommended daily amount.
• 70% NRV means it provides part of your daily needs, with the rest expected to come from your diet.

NRVs are general guidelines designed for the average adult to prevent deficiency, not specifically tailored to individual pregnancy needs

Exceeding the safe intake is uncommon, but extremely high doses (+3000mg) may cause risks. Our recommended dosages are always safely within clinical guidelines.

No, this is often intentional and safe. During pregnancy, requirements for certain nutrients increase, and standard NRVs do not always reflect optimal pregnancy needs. Some nutrients are therefore included above 100% to help ensure adequate intake, particularly where absorption varies, dietary intake is inconsistent, or requirements are higher. All levels used in prenatal supplements are set within established safe limits.

It’s also worth noting, NRVs are set well below the upper safe limits. This means that consuming more than 100% of the NRV is typically still well within safe, tolerable levels.

Not necessarily. Nutrients are included at different levels depending on how much is typically obtained from food, how well the body absorbs the nutrient, and how requirements change during pregnancy. Some nutrients are intentionally below 100% because diet usually provides the remainder, while others are higher to help ensure adequate intake.

Prenatal supplements are formulated to remain within safe limits when combined with a normal, balanced diet. However, you should avoid taking additional supplements containing the same nutrients unless advised by a healthcare professional.

Yes. Supplements are designed to support, not replace, a healthy diet. A balanced diet provides additional vitamins, minerals, fibre, protein, and other beneficial nutrients not found in supplements. Prenatal supplements help fill common nutritional gaps and provide consistency when dietary intake varies.

Folate requirements increase significantly during pregnancy as it supports normal foetal development. The standard NRV is lower than the amount commonly recommended in pregnancy guidelines, so providing 400µg helps ensure women meet recommended intake even if dietary intake varies.

The NRV for vitamin D is based on preventing deficiency in the general adult population, rather than optimising levels during pregnancy. Many women in the UK have low vitamin D levels, especially during autumn and winter. A higher amount helps support immune function, bone health for mother and baby, and maintaining healthy vitamin D status throughout pregnancy, while remaining within recognised safe intake levels.
