Ginger Supplement Side Effects: 7 Risks and Drug Interactions
Is Ginger Completely Safe?
Many people assume ginger is harmless because it is a common kitchen spice, but capsules deliver a concentrated amount every day. That is why it is worth understanding ginger supplement side effects before you start, and knowing who should avoid ginger or ask a doctor first. Here are 7 side effects and drug interactions, with practical tips to reduce them.
Common Ginger Supplement Side Effects
Most ginger supplement side effects are mild and affect the digestive system. They become more likely with high doses or when capsules are taken on an empty stomach, and they usually settle when the dose is lowered or split.
1. Heartburn
This is the most common of all ginger supplement side effects and can be troublesome for people with acid reflux. Taking capsules with food usually helps.
2. Gas and Belching
Some people notice bloating or ginger-flavoured burps. Splitting the dose across two meals often reduces this.
3. Mouth and Throat Irritation
Swallowing a capsule without enough water can cause a burning feeling in the throat, which is why the Nature’s Way label says to take it with a full glass of water.
4. Diarrhoea at High Doses
Going above the studied range of about 1 to 1.5 g a day can cause loose stools or mild cramps.
Drug Interactions: The Most Serious Ginger Supplement Side Effects
5. Blood Thinners and Antiplatelet Drugs
Ginger may reduce platelet clumping, which in theory raises the risk of bleeding with warfarin, aspirin or clopidogrel. It may also add to the effect of anti-inflammatory painkillers, which many older adults take for joint pain; our guide to joint pain relief for seniors explains safer options. If you take a blood thinner, ask your doctor first, and stop the capsules before any surgery or dental extraction at a time your doctor sets.
6. Diabetes and Blood Pressure Medicines
Some studies suggest ginger may lower blood sugar slightly and may affect blood pressure. If you take medicines for diabetes or blood pressure, check your readings regularly and tell your doctor.
7. Gallstones
Ginger may increase bile flow, so the NOW label advises people with gallstones or a heart condition to consult a doctor before use.
Who Should Talk to a Doctor First?
- Pregnant and breastfeeding women; pregnant women should only use ginger for nausea with a doctor’s approval.
- Anyone taking blood thinners or regular anti-inflammatory painkillers.
- People with diabetes, high blood pressure or heart disease.
- People with gallstones.
- Anyone with surgery coming up.
- Children, as the capsules listed here are for adults.
How to Reduce Ginger Supplement Side Effects
- Start low, for example 1 capsule of NOW Ginger Root 550 mg daily.
- Take capsules with a meal, as the Solaray Ginger 100 VegCaps and Solaray Ginger 180 VegCaps labels direct: 2 capsules daily with a meal.
- Drink a full glass of water with every dose, as the Nature’s Way Ginger Root 1100 mg label states.
- Do not combine more than one ginger product on the same day.
These simple steps prevent most ginger supplement side effects and help you find the dose that suits you without heartburn or belching. Here is a dose comparison to help you choose:
| Product | Amount per serving | Directions | Pack |
|---|---|---|---|
| NOW Ginger Root 550 mg | 550 mg per capsule | 1 capsule daily | 100 veg capsules |
| Solaray Ginger 1100 mg | 1,100 mg per 2 capsules | 2 capsules daily with a meal | 100 VegCaps |
| Solaray Ginger 1100 mg (value size) | 1,100 mg per 2 capsules | 2 capsules daily with a meal | 180 VegCaps |
| Nature’s Way Ginger Root 1100 mg | 1.1 g per 2 capsules | 2 capsules daily with a full glass of water | 240 vegan capsules |
Signs You Should Stop and See a Doctor
- Unusual bleeding, such as bleeding gums or unexplained bruising.
- Vomiting blood, black stools or severe abdominal pain.
- Persistent vomiting, dehydration or unexplained weight loss.
- A rash or swelling that suggests an allergy.
Ginger Supplement Side Effects: Frequently Asked Questions
Are ginger supplement side effects worse than with fresh ginger?

Most studies lasted a few weeks, so ask your doctor before using it daily for several months.
Does ginger harm the liver or kidneys?
There is no strong evidence of harm at usual doses, but people with liver or kidney disease should check with a doctor before any supplement.
