Natural Orange Extract
Also known as: Sweet orange, Orange extract, Orange peel extract, Citrus extract, Citrus sinensis
Overview
*Citrus sinensis*, widely known as the sweet orange, belongs to the Rutaceae family and is predominantly sourced from the fruit's peel, juice, and seeds. This natural extract is rich in bioactive compounds, specifically flavonoids and carotenoids, that confer various potential health benefits. These include weight management, enhanced cardiovascular health, and improved skin hydration. The research concerning *Citrus sinensis* extract is moderate to high in quality, with several clinical trials and systematic reviews endorsing beneficial health outcomes, although some findings are inconsistent and variable in their quality. As such, the extract is commonly found in wellness products and functional foods, not only due to its health benefits but also for its appealing flavor profile.
Benefits
The evidence-based benefits of *Citrus sinensis* extract encompass: 1. **Weight Loss and Body Composition**: Significant reductions in body weight, BMI, waist, and hip circumference have been documented among overweight individuals, showcasing moderate evidence for weight loss. 2. **Cardiovascular Health**: While mixed results regarding lipid profiles have been noted, some studies indicated favorable changes in fasting glucose and lipid levels from orange juice consumption, with limited consistent effects on HDL and LDL levels. 3. **Skin Health**: Meta-analytical findings suggest substantial improvement in skin hydration and reduced transepidermal water loss, though effects on skin elasticity and wrinkle depth are less pronounced. Notably, these benefits appear most relevant for overweight populations, with observable improvements typically occurring within 8-12 weeks of regular usage.
How it works
The bioactive flavonoids and carotenoids in *Citrus sinensis* significantly impact metabolic functions tied to glucose and lipid metabolism. Their antioxidant and anti-inflammatory properties promote general wellness and support various biological systems, including the digestive and cardiovascular systems. The absorption and effectiveness of these compounds can be influenced by the extraction method and product formulation, thereby affecting their bioavailability and interaction with metabolic pathways related to oxidative stress and inflammation.
Side effects
Overall, *Citrus sinensis* extract is considered safe when consumed in moderation; however, extensive long-term safety data remain limited. The occurrence of common side effects is rare, with gastrointestinal discomfort reported in fewer than 5% of individuals. While no significant rare adverse effects have been consistently documented, those with citrus allergies should completely avoid the extract. Potential drug interactions may arise, especially with medications affecting blood pressure or glucose levels, although specific interactions require further investigation. Pregnant and nursing women are advised to consult healthcare professionals prior to use due to insufficient data on safety in these groups.
Dosage
Dosage recommendations for *Citrus sinensis* extract can vary widely. Some studies endorse intakes up to 500 mL of orange juice daily or specific extract dosages, with suggested amounts including 750 mL for males and 500 mL for females. There is no established maximum safe dosage; however, caution is advised when consuming high dosages because of potential interactions and side effects. Regular daily intake is usually recommended, and the extract form (juice vs. concentrated extract) may play a role in the outcomes. It is important to note that factors such as formulation and dietary context can impact the bioavailability of the extract's beneficial compounds.
