FucoThin® fucoxanthin

9 Apr 2026

FucoThin® fucoxanthin is the most exciting new fat-burning carotenoid in the world's supplement ingredient market. It is extracted from brown algae Undaria pinnatifida or other algae as requested and produced using Jiejing's patented technology. FucoThin® is available as an oil form for softgel and as a microencapsulated powder for tablets and hard-shell capsules.

Benefits and mechanisms

Fucoxanthin naturally promotes fat breakdown, inhibits excessive fat production, reduces fat deposition, balances calorie conversion, improves leptin resistance, stimulates mitochondrial proliferation, and enhances cholesterol and lipid metabolism. The static fat-burning mechanism of fucoxanthin is mainly manifested in the following three ways:

• By promoting an increase in the number of mitochondria, stimulating mitochondrial metabolic function and improving overall cellular metabolism, especially by promoting the transformation of fat-storing white fat cells into fat-burning brown fat cells, thus significantly reducing the weight of white adipose tissue (WAT) in the waist and abdomen, achieving a firmer and slimmer waist and abdomen.
• By stimulating the expression of mitochondrial uncoupling protein 1 (UCP1), endoplasmic reticulum, and various metabolic enzymes, it promotes fat breakdown and thermogenic conversion (for every 1°C increase in body temperature, bodily functions and immunity can increase by 5–6 times), reducing blood lipids, liver fat, and subcutaneous fat, thus demonstrating an overall healthy fat loss and body shaping effect.
• By promoting the generation and increase of muscle tissue, it relies on muscle tissue to break down, consume, and metabolise fat, rather than self-destructive weight loss methods such as deliberate anorexia, extreme dieting, or other harmful practices, thus achieving the ideal effect of healthy fat loss without worrying about rebound.

Studies have found that fucoxanthin can not only reduce overweight and levels of triglycerides and total cholesterol, effectively preventing atherosclerosis and plaque formation. Additionally, it can reduce the risk of oxidative stress caused by obesity by increasing the content and activity of antioxidant enzymes (such as SOD, GPX, and CAT) in the liver and plasma, thereby reducing the content of reactive oxygen species (ROS), free radicals, and lipid peroxides in the body.
