Quercetin and Pregnancy: Is It Safe?

Quercetin is a powerful antioxidant and anti-inflammatory compound with a growing fan base in the longevity world. But when it comes to pregnancy, its safety remains a subject of caution and controversy.

Let’s explore the science, expert opinions, and safer alternatives to support maternal health during pregnancy.

Quercetin is a plant flavonoid found in:

• Apples

• Onions

• Berries

• Grapes

• Broccoli

It’s known for its ability to:

• Neutralise oxidative stress

• Lower inflammation

• Support cardiovascular and immune health

• Act as a senolytic , helping clear damaged “zombie cells”

These properties make quercetin a favourite in anti-ageing stacks. But pregnancy introduces a different set of concerns.

We don’t know yet. The safety of quercetin supplementation during pregnancy has not been conclusively established .

• Animal and test-tube studies suggest potential benefits, but

• Human studies on pregnant women are extremely limited

• There’s no clear evidence of harm — but also no proof of safety

Until more is known, most experts recommend avoiding quercetin supplements during pregnancy unless prescribed by a doctor.

In theory, quercetin might help:

• Lower blood pressure

• Reduce oxidative stress , supporting foetal development

• Support immune health during this high-demand period

But again, these are theoretical benefits , not confirmed outcomes — and must be weighed against the unknowns.

Many obstetricians and functional medicine doctors advise against using quercetin while pregnant, citing:

• Lack of clinical safety data

• Potential for unknown effects on foetal development

• A precaution-first approach to supplementing in pregnancy

Until larger-scale human trials are conducted, most professionals opt for better-studied alternatives.

Instead of quercetin, consider these pregnancy-safe nutrients with strong clinical backing:

1. Folic Acid – Supports neural tube development and prevents birth defects

2. Iron – Critical for blood volume and oxygen delivery

3. Calcium – Helps form the baby’s bones and teeth

4. Vitamin D – Supports immune function and maternal–foetal bone health

5. Omega-3 (DHA) – Supports brain and eye development

All of these are routinely recommended and studied for maternal safety.

The Zombie is For Youth’s advanced quercetin supplement, formulated with Quercetin Phytosome™ , which is:

• Up to 20x more bioavailable than standard quercetin

• Sourced, encapsulated, and bottled in Europe and Singapore

• Designed to clear senescent cells , reduce inflammation, and enhance immunity

It’s ideal for longevity support outside of pregnancy , especially for ageing, inflammation, allergies, or immune health.

But during pregnancy, we recommend pausing use unless cleared by a healthcare provider.

Q: Can I take quercetin from food while pregnant?
Yes — normal dietary intake from fruits and vegetables is generally safe.

Q: Can I take The Zombie – Quercetin if I’m pregnant?
Not unless specifically advised by your doctor. The safety of quercetin supplements during pregnancy is not yet confirmed.

Q: Is quercetin safe while breastfeeding?
There is also limited research. Speak with your paediatrician before use.

Q: Are there safer antioxidant options during pregnancy?
Yes — consider Vitamin C , Vitamin E , and a balanced antioxidant-rich diet instead.

Q: When can I restart quercetin postpartum?
Generally safe once you’re no longer pregnant or breastfeeding — but check with your healthcare provider first.

Quercetin offers remarkable benefits for immunity, inflammation, and cellular longevity — but its safety during pregnancy hasn’t yet been proven.

For now:

• Stick to food sources (fruits and vegetables)

• Avoid supplementing unless your doctor advises it

• Choose clinically backed alternatives like folic acid, iron, and vitamin D to support maternal health

At For Youth, we’re passionate about evidence-based longevity — but that starts with safety first , especially during pregnancy.
