Grapefruit Extract Naringin Supplement to Support Skin and Metabolic Health*

Grapefruit Extract is an extract of grapefruit standardized to 99% naringin, the primary bioactive compound found in grapefruit.* Naturally rich in fiber and low in calories, grapefruit has long been associated with balanced dietary practices.* This concentrated naringin formula is now available in supplement form at SuperSmart.

What’s Inside Our Grapefruit Supplement?

This supplement’s quality may stem from the unique nutritional profile of pomelo. Though often mistaken for one another, pomelo and grapefruit are two distinct citrus species, with grapefruit being more commonly consumed in the West. This dietary supplement is formulated with pomelo, also known as Citrus paradisi, a fruit that may offer naturally occurring bioactive compounds of interest.*

Obtained through extraction from the whole fruit—including the pulp, seeds, and skin of pomelo—this extract is then processed into a convenient dietary supplement form.* In line with current regulations, Grapefruit Extract is formulated without synthetic additives.

In addition, this extract provides naturally occurring bioflavonoids—antioxidant compounds that may play a supportive role in cellular protection and overall well-being.* Among these, the key constituent is naringin, a flavonoid heteroside responsible for the distinctive bitter taste of pomelo and grapefruit. Concentrated in the fruit’s pith, naringin is also used in various products, including certain tonic beverages.*

Potential Benefits of Naringin*

While grapefruit is sometimes included in balanced dietary routines, its potential biological activity has also attracted scientific interest:

• Researchers have studied its flavonoid content for potential antioxidant activity, which may help reduce oxidative stress and support healthy aging at the cellular level.*
• Pomelo extract has been investigated for its possible influence on immune and inflammatory pathways, although more research is needed to understand its full effects.*
• Though the benefits of naringin are still being explored, early research suggests potential roles in areas such as antioxidant defense, lipid metabolism, and nervous system support.*

Potential Role of Naringin in Metabolic Support*

Naringin, a key compound found in grapefruit extract, has been studied for its potential role in supporting metabolic health and body composition.* This supplement also provides other naturally occurring flavonoids that may contribute to overall wellness when paired with a balanced diet and active lifestyle.*

Some research has examined grapefruit in the context of lowering body weight, though the underlying mechanisms are not yet fully understood.* Its naturally low-calorie content may contribute to its appeal as part of a calorie-conscious diet.*

Data from the 2003–2008 National Health and Nutrition Examination Survey (NHANES) suggested that individuals who regularly consumed grapefruit or grapefruit juice tended to have lower body weight and waist circumference on average.* However, this observational data does not establish causation and further research is needed.*

In a study involving 85 overweight adults, researchers observed that consuming grapefruit before meals was associated with reduced appetite and a greater sense of fullness.* In another study of 91 individuals with elevated body weight, those who consumed grapefruit in various forms experienced greater changes in weight over time compared to the placebo group.* While promising, these findings are preliminary and should be interpreted with caution.*

For those who prefer not to consume grapefruit daily, grapefruit extract may offer a convenient alternative.* Providing a concentrated source of naturally occurring compounds like naringin, this supplement may offer a way to support wellness without the need to eat the fruit every day.*

Potential Role of Grapefruit Extract in Skin Health*

Naringin, a key compound in grapefruit extract, has been studied for its potential role in supporting skin health.* But what does that really mean?

Grapefruit extract capsules contain naturally occurring antioxidants that may help support the body’s natural defense against oxidative stress.* Exposure to environmental factors like sunlight may increase the presence of free radicals in the skin, which are thought to play a role in visible skin changes associated with aging over time.*

When free radicals are kept in balance, the skin may have an opportunity to maintain its natural resilience and appearance over time.* Some research suggests that supporting antioxidant activity could play a role in helping the skin respond to everyday oxidative stress—one of many reasons grapefruit extract is being explored for its potential role in skin health.*

Grapefruit extract has been studied for its potential to support a balanced inflammatory response, which may help the skin cope with environmental stressors such as redness or irritation.* Some early research suggests it might also play a role in promoting skin clarity and supporting the body’s natural repair processes, potentially through its influence on circulation.* While topical grapefruit formulations exist, taking a grapefruit naringin supplement may also contribute to overall skin wellness as part of a broader routine.*

Potential Role of Naringin in Immune and Inflammatory Balance*

Naringin, a compound found in grapefruit extract, has been studied for its potential antimicrobial properties in laboratory settings.* Some research suggests it may help create an environment that is less favorable to certain types of microorganisms.* Other studies have explored grapefruit seed extract (GSE) as a natural compound with properties that may support the body’s defense against external stressors.* Additional research has investigated its potential influence on yeast cell mechanisms, though findings are still preliminary.*

Grapefruit extract has been studied for its potential to support healthy circulation, which may help maintain optimal delivery of oxygen and nutrients throughout the body.* When circulation is compromised—such as during periods of inflammation—tissues may be less efficient at receiving what they need, which could impact overall wellness.*

However, research suggests that grapefruit extract may help support the body’s natural response to certain stressors.* This potential benefit may be linked to its antioxidant content, which has been studied for its possible role in supporting healthy circulation and tissue function.*

What to Know About Grapefruit Extract Tolerance and Use*

Grapefruit extract is generally well tolerated, but as with any supplement, it's important to understand how it is sourced and manufactured.* Variations in production practices may affect the overall quality or consistency of a supplement.*

To ensure a well-tolerated experience with naringin supplements, it's important to choose a high-quality grapefruit extract from a reputable source.* Some manufacturers may use less refined methods. Opting for a carefully formulated product may help support consistency and purity.*

It’s always a good idea to speak with a healthcare provider before starting any new supplement, especially if you are currently taking medications or have underlying health conditions. Consulting a professional can help ensure the product aligns with your individual needs. As with any wellness product, it's also helpful to review available research and make informed decisions based on your personal health goals.*
