Lemon Peel Organic Fruit Powder
Also known as: Lemon peel, Lemon skin, Citrus limon
Overview
Lemon peel is the outer layer of the lemon fruit (*Citrus limon*) and is recognized for its rich content of polyphenols, flavonoids, vitamin C, and D-limonene. This ingredient is largely used as a dietary supplement due to its antioxidant and anti-inflammatory properties, which may benefit heart health, immune function, and digestive health. Lemon peel is high in dietary fiber and various bioactive compounds, especially eriocitrin and hesperidin. Research into lemon peel has shown promising results, particularly in animal and in vitro studies, though high-quality human trials are still limited, indicating moderate research maturity. Overall, lemon peel is celebrated for its potential to enhance health and well-being.
Benefits
The primary benefits of lemon peel include significant antioxidant activity, with evidence from multiple assays (FRAP, DPPH) confirming its high phenolic content. In animal studies, it has shown to reduce intestinal inflammation and barrier defects, enhancing gut health. Secondary benefits involve potential cardiovascular health improvements, as flavonoids and vitamin C may lower heart disease risk by reducing cholesterol levels, supported by a review showing a 5% reduction in risk with increased flavonoid intake. Additionally, in a study involving children with excess weight, lemon peel supplementation led to improvements in blood pressure and LDL cholesterol. Overall, the evidence suggests that lemon peel could provide measurable health improvements, particularly in populations with specific health concerns.
How it works
Lemon peel operates through its key compounds—eriocitrin, hesperidin, and D-limonene—that act primarily as antioxidants, scavenging free radicals to reduce oxidative stress. These compounds influence inflammatory pathways by modulating gene expression related to inflammation and decreasing pro-inflammatory cytokine production. Lemon peel also contributes to digestive health by enhancing intestinal barrier function and has shown potential in lowering cholesterol levels, impacting cardiovascular health.
Side effects
Lemon peel is generally considered safe for consumption in moderate amounts, with few significant side effects reported. Common side effects (>5%) are absent, while gastrointestinal discomfort and allergic reactions are rare (<5%). No significant rare side effects (<1%) have been documented. There are potential interactions with certain medications due to high levels of vitamin C and flavonoids, although evidence is limited. Individuals with citrus allergies should exercise caution. Pregnant or breastfeeding women should consult healthcare professionals before use to ensure safety, as specific contraindications have not been well documented.
Dosage
The effective dose range for lemon peel powder is not definitively established, but studies have typically employed doses ranging from 1-2 grams per day. These dosages correspond to observed benefits, including improved intestinal health and antioxidant capacity. No specific timing recommendations are indicated for usage. The maximum safe dose is undetermined; however, high doses of vitamin C and flavonoids should be approached cautiously. Cloud point extraction (CPE) and methanol extraction are effective methods for preserving bioactive compounds—bioavailability may depend on the extraction method and composition. A balanced diet may facilitate optimal absorption.
