Orange Peel Organic Fruit Powder
Also known as: Orange peel, Orange peel extract, Orange peel powder, _Citrus sinensis_ L.
Overview
Orange peel is the outer layer of the orange fruit, produced primarily as a by-product from the juice industry. Rich in phytochemicals such as flavonoids (naringin and hesperidin), triterpenes, and dietary fiber, it has emerged as an interesting dietary supplement with potential health benefits. The powder is known for its high antioxidant properties and is used as a natural food additive and functional ingredient aimed at improving cardiovascular health and glucose regulation. Although several studies, mainly in animal models, suggest its benefits, human clinical trials are limited, emphasizing the need for further research to establish its efficacy and safety levels definitively.
Benefits
Research indicates that orange peel extracts have potential benefits for cardiovascular health by inhibiting trimethylamine N-oxide (TMAO) production, which is linked to heart disease risk. Additionally, naringin and naringenin compounds in orange peel have anti-hyperglycemic effects, improving insulin sensitivity and glucose metabolism, shown in diabetic animal studies. Furthermore, the antioxidant capacity of orange peel may protect against oxidative stress. However, the specific effect sizes and confidence intervals for human trials remain unclear, and further rigorous studies are necessary to substantiate these claims and establish the ingredient's effectiveness in human populations.
How it works
Orange peel works primarily by inhibiting enzymes that produce TMA, subsequently reducing TMAO levels and thereby lowering the risk of cardiovascular diseases. The flavonoids enhance insulin sensitivity and aid glucose metabolism, compelling a beneficial interaction with the endocrine system. Additionally, the antioxidants present help in scavenging free radicals, leading to reduced oxidative stress within the body.
Side effects
Generally safe for consumption, orange peel does not have well-documented common or severe side effects in human clinical studies. Limited information is available, with no current adverse effects reported in the literature. There is potential for interactions with medications affecting glucose and lipid metabolism, although specifics remain vague. Individuals with diabetes or cardiovascular disease should consult healthcare professionals before use, particularly pregnant or breastfeeding women, due to limited safety data in these populations. As with any supplement, caution and professional guidance are advised when altering diet or introducing new supplements.
Dosage
The optimal dosage of orange peel powder has not been definitively established in human trials, with effective doses observed in animal studies varying and typically based on body weight. Future research is critical to determine safe and effective doses for specific health outcomes. While the timing of consumption is not specified, factors such as base extraction methods can influence bioavailability; it is suggested to follow product-specific guidelines or consult a health professional regarding dosage, especially adjusting for individual health goals.
