1. Introduction: Are there natural foods that help regulate blood sugar?
Many of us are interested in natural ways to support healthy blood sugar levels. In particular, the question: “Are there natural foods high in naringenin that help regulate blood sugar?” is more relevant than ever. The answer is a clear yes, and the science behind it is fascinating.
In a world where we are constantly surrounded by processed foods and hidden sugars, more and more people are looking for natural alternatives to help keep their bodies in balance. That is where naringenin comes in—a powerful flavonoid found mainly in citrus fruits, with impressive health benefits, particularly for insulin and blood sugar regulation.
In this article, we take a deep dive into the science of naringenin. We explain how it works, which foods are the best sources, and how you can easily add it to your daily routine to support your health naturally.
2. What is naringenin? A powerful natural compound
Naringenin (4,5,7-trihydroxyflavanone) is a polyphenol in the large flavonoid family. These secondary plant compounds are responsible for the vivid colours of many fruits and vegetables and are known for their antioxidant properties. Naringenin is found in particularly high concentrations in citrus fruits and contributes to grapefruit’s slightly bitter taste.
But naringenin does more than taste good. Research in recent years suggests that this compound has a wide range of pharmacological effects, from anti-inflammatory to neuroprotective properties. Of particular note is its potential to positively affect glucose and insulin metabolism.
🌿 About GUYA and our work
At GUYA, we value the power of nature. We work directly with Kichwa communities in Ecuador who grow plants such as guayusa and our delicious Amazonian orange tea in traditional chakra forest gardens. Transparency and scientific grounding are especially important to us.
3. How naringenin regulates blood sugar: the science
Naringenin’s antidiabetic properties are impressive and have been supported by numerous studies. The compound acts at several points in the body to improve insulin sensitivity and stabilise blood sugar. A comprehensive review by Den Hartogh & Tsiani (2019) summarises these mechanisms well [1].
🔬 Naringenin’s multimodal effects
1. Skeletal muscle: Naringenin increases glucose uptake into muscle cells. It activates the AMPK signalling pathway, a key regulator of cellular energy metabolism. This leads to more of the glucose transporter GLUT4 moving to the cell surface, allowing more sugar to be taken up from the blood.
2. Liver: In the liver, naringenin inhibits gluconeogenesis, the production of new glucose. As a result, the liver releases less sugar into the blood, which is particularly relevant for fasting blood glucose.
3. Adipose tissue: Naringenin reduces inflammatory responses in adipose tissue, which are often linked to insulin resistance. It lowers the release of pro-inflammatory cytokines such as TNF-α.
4. Pancreas: Studies suggest that naringenin may protect the insulin-producing β-cells of the pancreas from cell death (apoptosis) and improve their function.
💡 What this means for you:
Naringenin helps your body use the sugar already in your blood more efficiently while reducing excessive production of new sugar. A double benefit for stable blood sugar!
4. The best natural sources of naringenin
The good news is that naringenin is found in many delicious, nutritious foods. You do not need expensive supplements to benefit from these foods. Here are some of the top sources:
| Food | Naringenin content |
|---|---|
| Grapefruit | Very high (up to 43.5 mg/100 mL of juice) |
| Oranges (especially sour varieties) | High |
| Tomatoes (especially the skin) | Medium |
| Sour cherries | Medium |
| Greek oregano | Low |
Our Amazonian orange tea is made from the whole fruit, including the peel, which is particularly rich in naringenin and the related flavonoid hesperidin. A delicious, easy way to get your daily dose!
5. Case study: naringenin reduces insulin resistance and body weight
The theory sounds promising, but what about in practice? A fascinating case study by Murugesan et al. (2020) in the Journal of Medicinal Food reported notable results [2].
🏥 The study in detail
A woman with diabetes took 150 mg of naringenin three times a day for 8 weeks. The results were notable:
- Weight loss: She lost 2.3 kg of body weight.
- Insulin levels: Her insulin level fell by 18%, a clear sign of improved insulin sensitivity.
- Metabolic rate: Her metabolic rate measurably increased.
- Safety: No side effects were reported.
The researchers concluded that naringenin is safe and, by activating PPARα and PPARγ, two important metabolic regulators, reduces body weight and insulin resistance.
6. GUYA’s recommendation: orange tea and guayusa
For natural support of your blood sugar levels, we recommend combining two of our Amazonian products:
🍊 Amazonian orange tea
Enjoy a cup of our aromatic orange tea every day. It is a natural source of naringenin and hesperidin and gently supports your body. Enjoy it hot or as a refreshing iced tea.
🌿 Guayusa tea
Pair the orange tea with our classic guayusa tea. As we explain in our article on the effects of guayusa, guayusa contains chlorogenic acid, which also contributes to blood sugar regulation. A winning combination for energy and wellbeing!

❓ Which foods have the most naringenin?
Grapefruits have the highest amount, followed by sour oranges. Tomato skins and sour cherries are also good sources.
❓ Is naringenin safe?
Yes. In the amounts found in foods, naringenin is absolutely safe. Clinical studies using higher doses also showed no side effects.
❓ How quickly does naringenin work?
Its effects on blood sugar tend to be long-term and form part of a healthy lifestyle. The case study showed significant improvements after 8 weeks of consistent use.
