# Langsat **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/langsat **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-28 **Evidence Score:** 4 / 10 **Category:** Other **Also Known As:** Lansium parasiticum, Lanzones, Duku, Longkong, Buah langsat, Lanzone, Kokosan, Pisitan, Lansones ## Overview Langsat (Lansium domesticum) contains high concentrations of vitamin C and phenolic antioxidants that support immune function and cellular protection. The fruit's bioactive compounds enhance [white blood cell](/ingredients/condition/immune-support) activity and neutralize [free radical](/ingredients/condition/antioxidant)s through direct antioxidant mechanisms. ## Health Benefits - Langsat is packed with vitamin C, which boosts immune function by enhancing [white blood cell](/ingredients/condition/immune-support) activity. This helps the body fend off infections more effectively. - Its antioxidants combat [oxidative stress](/ingredients/condition/antioxidant), reducing cellular damage and slowing aging. Antioxidants neutralize free radicals, protecting cells. - Langsat contains dietary fiber, promoting [digestive health](/ingredients/condition/gut-health) by aiding bowel regularity. Fiber also supports gut microbiota balance. - The fruit has anti-inflammatory properties, which can reduce chronic inflammation linked to diseases. This is achieved through the inhibition of [pro-inflammatory cytokine](/ingredients/condition/inflammation)s. - Rich in polyphenols, Langsat supports [cardiovascular health](/ingredients/condition/heart-health) by improving blood vessel function. Polyphenols enhance endothelial function, reducing heart disease risk. - It contains potassium, which helps regulate blood pressure by balancing sodium levels. This mineral supports heart health and reduces hypertension risk. - Langsat's natural sugars provide a quick energy boost, enhancing [physical performance](/ingredients/condition/energy). These sugars are easily metabolized, supplying immediate fuel. ## Mechanism of Action Langsat's vitamin C enhances [immune function](/ingredients/condition/immune-support) by promoting neutrophil chemotaxis and supporting T-lymphocyte proliferation. The fruit's phenolic compounds, including flavonoids and tannins, donate electrons to neutralize [reactive oxygen species](/ingredients/condition/antioxidant) (ROS) and inhibit lipid peroxidation. These antioxidants protect cellular membranes by scavenging hydroxyl radicals and superoxide anions. ## Clinical Summary Limited clinical research exists specifically on langsat supplementation. Most evidence comes from nutritional analyses showing vitamin C content ranging from 20-30mg per 100g of fresh fruit. In vitro studies have demonstrated [antioxidant activity](/ingredients/condition/antioxidant) of langsat extracts, but human trials measuring immune outcomes or oxidative stress markers are lacking. Current evidence is primarily based on traditional use and preliminary laboratory studies. ## Nutritional Profile - High in vitamin C and vitamin A. - Contains dietary fiber. - Low in calories and fat. - Provides natural sugars for energy. ## Dosage & Preparation Consume 100-200 grams of fresh langsat daily. Consult a healthcare provider before use. ## Safety & Drug Interactions Langsat fruit is generally safe when consumed as food, with no known serious adverse effects reported. High doses of vitamin C from concentrated extracts may cause gastrointestinal upset, including nausea and diarrhea. No significant drug interactions have been documented, though vitamin C can enhance iron absorption. Pregnant and breastfeeding women should limit intake to food amounts due to insufficient safety data on concentrated extracts. ## Scientific Research Studies have shown langsat's potential [antioxidant](/ingredients/condition/antioxidant) properties due to its phenolic content. Its vitamin C levels contribute to immune health, though more research is needed. ## Historical & Cultural Context Langsat has been traditionally consumed in Southeast Asian countries for its refreshing taste and is often used in local desserts and beverages. It holds cultural significance in regional festivals. ## Synergistic Combinations Mango, Pineapple, Papaya ## Frequently Asked Questions ### How much vitamin C is in langsat fruit? Fresh langsat contains approximately 20-30mg of vitamin C per 100g serving. This provides about 22-33% of the daily recommended vitamin C intake for adults. ### Can langsat help prevent colds and infections? Langsat's vitamin C content may support immune function, but there's no clinical evidence specifically showing langsat prevents infections. The vitamin C levels are moderate compared to citrus fruits. ### What antioxidants are found in langsat? Langsat contains phenolic compounds including flavonoids, tannins, and vitamin C that provide antioxidant activity. These compounds help neutralize free radicals and protect cells from oxidative damage. ### Is langsat safe to eat during pregnancy? Fresh langsat fruit is safe during pregnancy as part of a balanced diet. However, pregnant women should avoid concentrated langsat extracts or supplements due to limited safety data. ### How does langsat compare to other tropical fruits for antioxidants? Langsat has moderate antioxidant activity compared to other tropical fruits like acai or dragon fruit. Its primary benefit comes from vitamin C rather than unique phytochemicals found in other exotic fruits. ### Does langsat contain fiber, and how much per serving? Yes, langsat is a good source of dietary fiber, which supports digestive health and promotes regular bowel movements. A typical serving of langsat fruit (about 100g) contains approximately 1.5-2g of fiber, contributing to daily fiber intake goals. This fiber content makes langsat beneficial for maintaining healthy digestion and supporting gut health when consumed regularly. ### Who benefits most from eating langsat regularly? Individuals seeking to boost immune function, reduce oxidative stress, and support digestive health benefit most from regular langsat consumption. People with diets lacking in vitamin C and antioxidants, as well as those looking for natural sources of dietary fiber, can see particular advantages. Additionally, those interested in anti-aging nutrition may benefit from langsat's potent antioxidant profile, which helps neutralize free radical damage. ### How should fresh langsat be prepared to maximize nutrient retention? Fresh langsat should be eaten whole or segmented shortly after cutting to preserve water-soluble vitamin C and heat-sensitive antioxidants. Consuming it raw rather than cooking it helps maintain the maximum nutrient content, as heating can degrade vitamins. Storing langsat in a cool, dry place and consuming it within a few days of purchase ensures you get the most nutritional benefit from the fruit. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
