What is Manuka honey?

Manuka honey comes from New Zealand and is produced by bees that collect nectar from the Manuka plant (Leptospermum scoparium). It is known for its unique properties, which distinguish it from conventional honey. Due to its unique composition and high content of methylglyoxal, or MGO for short, Manuka honey is considered to be of particularly high quality. MGO is a natural component that occurs in significantly higher quantities in Manuka honey than in other types of honey.

 

What does MGO stand for?

MGO stands for methylglyoxal and is an important indicator of quality for Manuka honey. The higher the MGO value, the more concentrated this active ingredient is in the honey. Many manufacturers list the MGO content on the label, so that you, as a buyer, can get an idea of the intensity and quality of the honey.

What are the side effects of Manuka honey?

Manuka honey is a natural product with many benefits. However, you or others may experience side effects when consuming or using Manuka honey. However, virtually all of these side effects apply to honey in general and are not exclusive to Manuka honey.

Below is a list of possible side effects.

 

Allergic reactions

If you are allergic to pollen or bee products, you may also be allergic to Manuka honey. Typical symptoms include skin rashes, itching, swelling, or breathing difficulties. In this case, start by trying Manuka honey in very small amounts and gradually increase the amount.

If you know you are allergic to honey in general, consult a doctor before use. Especially if you have an existing allergy to bee stings or bee products, unwanted side effects may occur when taking or applying Manuka honey topically.

 

Gastrointestinal complaints

In rare cases, excessive consumption of honey can lead to bloating, diarrhea, or abdominal pain. This also applies to Manuka honey. The main active ingredient in Manuka honey, MGO, is largely broken down in the digestive tract and is not known to cause gastrointestinal discomfort. In fact, due to its beneficial properties, Manuka honey is often used to help alleviate digestive issues.

 

Effects on blood sugar

Although honey has a lower glycemic index than sugar, it can still raise your blood sugar levels. If you have diabetes, we recommend that you speak with your doctor before you start taking or using Manuka honey. He or she can tell you whether using it makes sense in your case, and if so, how and in what dosage. This way, you’ll be well-informed and can avoid unwanted side effects.

 

Risk of botulism in infants

For safety reasons, babies under one year of age should not be given honey, including Manuka honey. Honey may contain Clostridium botulinum spores, which can cause severe botulism in infants. This risk applies to Manuka honey just as much as to other types of honey.

Conclusion: The side effects mentioned mainly apply to honey in general. However, certain components in Manuka honey, particularly its high MGO content, can trigger more severe reactions in sensitive individuals. If you are allergic to bee products or pollen, have diabetes, or are considering giving honey to your baby, you should consult your doctor beforehand. An allergy test may also be helpful if you are unsure how your body reacts to Manuka honey. Start with small amounts to test your personal tolerance.

 

Who should be especially careful?

Certain groups of people should use Manuka honey with caution or consult a doctor beforehand:

  • Pregnant and breastfeeding women: Manuka honey is generally safe for pregnant women and breastfeeding mothers, but it is advisable to consult a doctor beforehand.
  • Infants under 1 year of age: As mentioned earlier, babies under one year of age are at a high risk of developing botulism from botulism spores in honey. For this reason, you should avoid giving Manuka honey to infants of this age.
  • People with diabetes: Due to the sugar content and its effect on blood sugar levels, people with diabetes should consult their doctor before taking this product.
  • People with allergies: Those with allergies should exercise caution and test for tolerance.

 

How to Use Manuka Honey in the Right Dosage – How to Avoid Side Effects

Using Manuka honey in moderation can help you minimize any potential side effects. Here are a few tips:

  • Start with small amounts, such as half a teaspoon a day.
  • Pay attention to how your body reacts, and increase the amount gradually.
  • Do not exceed the recommended daily dose.

Recommended dosage for Manuka honey and honey in general

  • Adults: 1–2 teaspoons per day
  • Children over 1 year of age: smaller amounts, by arrangement
  • Babies: No honey!

 

Manuka Honey Side Effects – The Bottom Line

The question of whether Manuka honey has side effects can be definitively answered as follows.

Side effects from Manuka honey are rare, but not impossible. Most people tolerate Manuka honey very well, but allergies, gastrointestinal issues, or effects on blood sugar can occur in rare cases. You should be especially cautious with babies under one year of age and if you have allergies.

Check in advance whether you’re tolerant of honey and be mindful of your portion size. Then nothing will stand in the way of your carefree enjoyment of Manuka honey.
