How Much Zinc During Pregnancy? Requirements, Supplements and Safe Dosage

How much zinc during pregnancy is appropriate cannot be answered with a single number. Zinc requirements change as pregnancy progresses and also depend on how efficiently zinc is absorbed from the diet. At the same time, many prenatal supplements already contain a relevant amount of zinc.

NUTRILAB MUNICH explains how much zinc is recommended during pregnancy, when additional supplementation may be appropriate and when total intake may become too high.

Key takeaways

• Depending on dietary composition and stage of pregnancy, around 7–13 mg of zinc per day is recommended.
• Requirements increase from the second trimester onwards.
• Inadequate zinc intake is more likely with vegan or strongly plant-based diets, chronic gastrointestinal disease, coeliac disease, previous gastrointestinal surgery or a very restricted diet.
• Zinc status is not routinely tested as part of standard prenatal care.
• A balanced diet can often provide sufficient zinc. Anyone using supplements should check their total daily zinc intake because chronically excessive intake can interfere with copper absorption.

How Much Zinc Per Day During Pregnancy?

The recommended daily amount of zinc in pregnancy depends mainly on two factors: the stage of pregnancy and the amount of phytate in the diet.

According to the German Nutrition Society's zinc reference values, recommended zinc intake during the first trimester ranges from approximately 7 to 11 mg per day, depending on dietary phytate intake. For many women, this is similar to the amount recommended before pregnancy.

From the second trimester onwards, recommended intake increases to approximately 9 to 13 mg per day. This reflects, among other factors, the increasing growth of the baby, as zinc is required for normal cell division and tissue growth.

Why is there a range rather than one exact zinc value? One important reason is phytate, a natural compound found in foods such as whole grains, legumes, nuts and seeds.

Phytate binds zinc in the intestine and reduces the proportion that can be absorbed. The German Nutrition Society's guidance on zinc therefore distinguishes between diets with low, moderate and high phytate intake.

With a diet low in phytate and including regular animal-derived zinc sources, requirements are closer to the lower end of the reference range. With vegetarian, vegan or otherwise strongly plant-based diets containing large amounts of whole grains and legumes, zinc requirements may be higher.

An intake that temporarily falls slightly below the recommended amount does not automatically mean that zinc deficiency is present. Nutrient intake should be considered over time rather than from one individual meal or day.

Zinc Requirements Before Pregnancy

Before pregnancy, zinc requirements correspond to those of non-pregnant women and vary according to dietary phytate intake.

Unlike folic acid, there is no general recommendation to take a zinc supplement routinely before conception. The main focus should be a balanced diet containing regular sources of zinc.

With a fully plant-based diet, it can be useful to consider zinc intake more closely during preconception planning and, where appropriate, discuss dietary intake with a qualified healthcare or nutrition professional.

Zinc Requirements During Pregnancy

During the first trimester, the German Nutrition Society recommends approximately 7 to 11 mg of zinc per day, depending on phytate intake.

From the second trimester onwards, recommended intake rises to around 9 to 13 mg per day because of the additional requirements associated with fetal growth and development.

This does not mean that an intake slightly below these values on an individual day immediately causes zinc deficiency.

Zinc Requirements During Breastfeeding

Zinc requirements remain increased during breastfeeding because zinc is secreted into breast milk.

A balanced diet continues to provide the foundation for adequate intake. Anyone using a postnatal multivitamin should check how much zinc it already contains before adding a separate zinc supplement.

NUTRILAB MUNICH's 03 femme postnatal contains 12 mg of zinc per daily dose.

Zinc Deficiency During Pregnancy: Risk Factors

A temporary intake below the reference value does not automatically mean that a zinc deficiency is present. The risk of inadequate zinc status becomes more relevant when intake remains low over time or when additional factors interfere with absorption.

Common risk factors include:

• vegan or vegetarian diets high in whole grains and legumes
• inflammatory bowel diseases such as Crohn's disease or ulcerative colitis
• coeliac disease
• previous gastric or intestinal surgery, including gastric bypass
• very restricted diets due to poor appetite, food preferences or avoidance of entire food groups
• use of high-dose iron supplements

If none of these factors is present, zinc requirements can often be covered through a varied diet.

Symptoms of Zinc Deficiency During Pregnancy

Zinc deficiency can cause a range of symptoms, but these symptoms are not specific to zinc and can have many other causes during pregnancy.

Possible signs include:

• recurrent infections
• slow wound healing
• rough or inflamed skin
• changes in taste or loss of taste
• unexplained loss of appetite

The German Nutrition Society explains in its guidance on zinc deficiency that none of these symptoms alone proves that zinc intake is inadequate. Changes in appetite and taste, for example, can also occur during pregnancy for reasons unrelated to zinc status.

If symptoms persist or additional risk factors are present, zinc intake and possible causes should be assessed medically. Routine zinc testing is not part of standard prenatal care.

Zinc Deficiency in Pregnancy: Possible Effects

Zinc is required for numerous metabolic processes, including normal immune function, wound healing, cell division and growth.

A severe zinc deficiency can therefore affect several aspects of maternal health and may also interfere with normal fetal development.

Effects on the mother

More pronounced zinc deficiency can be associated with skin changes, hair loss, impaired wound healing and persistent diarrhoea. Severe presentations are more likely in people with substantial malabsorption or markedly inadequate nutritional intake.

Lower blood zinc concentrations have also been observed in some pregnancy complications, including pre-eclampsia. However, this does not demonstrate that low zinc directly causes these conditions because inflammation and other physiological changes can also affect circulating zinc concentrations.

Effects on the baby

Zinc is required for cell division, tissue growth and multiple developmental processes. A pronounced deficiency may therefore interfere with normal fetal growth.

However, the effects of additional zinc supplementation on pregnancy outcomes are less straightforward than the biological importance of zinc might suggest.

A Cochrane review on zinc supplementation in pregnancy found no clear evidence that routine zinc supplementation meaningfully improved outcomes such as birth weight, gestational age or neonatal health.

Severe zinc deficiency also frequently occurs alongside other forms of malnutrition, making the independent effect of zinc difficult to isolate.

Evidence linking zinc deficiency to congenital abnormalities comes predominantly from animal models and cannot simply be transferred to humans.

Zinc-Rich Foods During Pregnancy

For most pregnant women, dietary intake is the main source of zinc.

Good sources include:

• beef and pork
• cheese, particularly hard cheeses
• milk, yoghurt and other dairy products
• eggs
• oats and whole-grain bread
• lentils, chickpeas and beans
• pumpkin seeds, sunflower seeds and cashews

Plant foods can contain considerable amounts of zinc, but the phytate they contain can reduce zinc absorption.

Preparation techniques that reduce phytate can therefore improve zinc availability from a plant-based diet. Useful approaches include soaking legumes before cooking, sprouting grains or seeds and using sourdough fermentation.

Whole grains and legumes do not need to be avoided because of their phytate content. They provide zinc and many other nutrients, while appropriate preparation can improve mineral bioavailability.

Can You Take Zinc During Pregnancy?

Yes, zinc can be taken during pregnancy when supplementation is appropriate.

However, zinc supplementation during pregnancy is not routinely recommended for every pregnant woman.

The Healthy Start Network's recommendations for pregnancy focus general supplementation recommendations on folic acid and iodine, with DHA recommended when fatty sea fish is not consumed sufficiently and iron supplementation based on diagnosed need.

Additional zinc may be considered when dietary intake is uncertain, for example with a vegan diet or with conditions and previous surgery that impair zinc absorption.

Before taking a higher-dose standalone zinc supplement, total intake and the reason for supplementation should therefore be assessed.

If you already use one of NUTRILAB MUNICH's pregnancy supplements, check the existing zinc content before adding another zinc-containing product.

Zinc Supplements During Pregnancy: Multivitamin or Standalone Zinc?

A well-formulated prenatal multivitamin can already contribute a substantial proportion of daily zinc intake.

Before adding a standalone zinc product, check how much zinc is already supplied by your existing prenatal supplement and consider the contribution from food.

NUTRILAB MUNICH currently provides:

• 01 femme prenatal: 11 mg zinc per daily dose
• 02 femme prenatal: 12 mg zinc per daily dose
• 03 femme postnatal: 12 mg zinc per daily dose

Different zinc compounds can differ in absorption. The NIH Office of Dietary Supplements' zinc fact sheet reports comparative data indicating that zinc citrate and zinc gluconate are absorbed well, while zinc oxide tends to be absorbed less efficiently.

Zinc Overdose During Pregnancy: What Are the Limits?

For adults, including pregnant women, a total zinc intake of 25 mg per day from food and supplements combined is used as the European tolerable upper intake level in the German risk assessment.

The German Federal Institute for Risk Assessment's recommendations on maximum zinc levels in supplements propose 6.5 mg of zinc per daily dose for an individual food supplement.

This 6.5 mg value is not a clinical toxicity threshold. It is a precautionary maximum proposed for supplements while accounting for additional zinc intake from food.

A zinc overdose during pregnancy is unlikely to result from normal foods alone. It is more likely when several zinc-containing supplements are combined, for example a prenatal multivitamin plus a standalone zinc tablet or an additional immune-support product.

What Happens If You Take Too Much Zinc?

Long-term excessive zinc intake can interfere with copper absorption and may eventually contribute to copper deficiency, anaemia and neurological problems.

High acute intakes can also cause:

• nausea and vomiting
• abdominal cramps or diarrhoea
• headache and dizziness
• loss of appetite

The NIH Office of Dietary Supplements notes that zinc doses of around 50 mg per day or more for several weeks can interfere with copper absorption.

To reduce the risk of excessive intake:

• check all supplements for their zinc content
• avoid combining several zinc-containing products without professional advice
• do not increase doses independently
• have the total intake reviewed if several supplements are being used

Zinc, Iron and Copper During Pregnancy

Iron, zinc and copper can influence one another when taken in higher supplemental doses.

According to the NIH Office of Dietary Supplements' guidance on zinc, taking 25 mg or more of supplemental iron at the same time as zinc can reduce zinc absorption and plasma zinc concentrations.

If higher-dose iron and zinc supplements are both required, taking them at different times can help avoid direct competition during absorption.

High zinc intake is also relevant for copper. The NIH guidance on copper explains that high zinc intake can interfere with intestinal copper absorption.

A practical approach is to:

• take zinc with food if it otherwise causes nausea
• separate higher-dose iron and zinc supplements
• check cold and immune-support products for additional zinc
• avoid long-term high-dose zinc supplementation without medical guidance

If you have been prescribed iron, this does not mean that zinc needs to be avoided altogether. The timing and total doses are what matter.

5 Myths About Zinc During Pregnancy

1. More Zinc Always Strengthens the Immune System During Pregnancy

Zinc is required for normal immune function, but that does not mean that taking additional zinc beyond requirements will continuously strengthen immunity.

Once zinc requirements are met, there is no established general benefit from simply increasing the dose. Excessive intake can instead interfere with copper metabolism.

2. A Blood Test Reliably Shows Whether You Are Zinc Deficient

A single zinc blood level has limitations.

Circulating zinc can be influenced by food intake, time of day, inflammation and physiological changes. Pregnancy can also affect measured concentrations.

A possible deficiency therefore needs to be considered alongside dietary intake, symptoms and relevant risk factors rather than from one laboratory value alone.

3. Zinc Supplements Treat Hair Loss

Hair loss has many possible causes and does not by itself indicate zinc deficiency.

Zinc supplementation should therefore not be used routinely for hair loss without assessing the likely cause.

4. A Plant-Based Diet Automatically Causes Zinc Deficiency

Vegetarian and vegan diets do not automatically cause zinc deficiency.

However, the risk of inadequate intake can be higher because plant-based diets often contain more phytate, which reduces zinc absorption.

The German Nutrition Society's information on zinc and phytate explains why total dietary composition and phytate intake matter when estimating zinc requirements.

5. Zinc Supplements Are Harmful During Pregnancy

Zinc is an essential trace element during pregnancy, and supplementation is not inherently harmful.

The relevant question is the total dose. Problems become more likely when several zinc-containing products are combined or when high amounts are taken over a prolonged period.

Zinc During Pregnancy: Frequently Asked Questions

How Much Zinc Can I Take in a Supplement During Pregnancy?

The German Federal Institute for Risk Assessment proposes a maximum of 6.5 mg zinc per daily dose of an individual food supplement.

This is a precautionary product-level recommendation rather than a medical toxicity threshold.

For total zinc intake from food and supplements combined, the European upper intake level used in the German risk assessment is 25 mg per day.

Can I Take Extra Zinc If My Prenatal Vitamin Already Contains Zinc?

If your prenatal vitamin already contains zinc, check the amount per daily dose before adding another product.

Adding a second zinc-containing supplement can increase total intake considerably without necessarily providing an additional benefit.

Is Zinc Routinely Tested During Prenatal Care?

No. Zinc status is not routinely measured as part of standard prenatal care.

Testing may be considered when there are relevant risk factors such as a highly restricted diet, chronic gastrointestinal disease, malabsorption or previous gastrointestinal surgery.

I Am Pregnant With Twins. Do I Need More Zinc?

There is no separate general zinc intake recommendation specifically for twin pregnancies in the source material underlying this article.

The standard pregnancy reference values therefore remain the basis unless an individual medical assessment indicates otherwise.

Can Zinc Help With Pregnancy Nausea?

There is not enough evidence to recommend zinc specifically as a treatment for pregnancy nausea.

High-dose zinc taken on an empty stomach can itself cause nausea and gastrointestinal discomfort, as described by the NIH Office of Dietary Supplements.

How Much Zinc During Pregnancy? Conclusion

With zinc in pregnancy, the aim is not to consume as much as possible. The goal is to meet requirements while avoiding unnecessary duplication between food, prenatal multivitamins and standalone supplements.

For most women, diet remains the foundation of zinc intake. Prenatal supplements can contribute a meaningful amount, while an additional standalone zinc product is most relevant when there is a specific reason to suspect inadequate intake or impaired absorption.

At NUTRILAB MUNICH, zinc is therefore considered in the context of diet, pregnancy stage and the other supplements already being used rather than as an isolated nutrient.
