Meet Xanthigen®

Developed by Nektium, Xanthigen® is a proprietary blend of wakame (also known as brown seaweed) and pomegranate seed oil.

Xanthigen® is rich in antioxidants and polyphenols. Our peer-reviewed, double-blind, placebo-controlled human clinical trial demonstrated its effect on weight management, particularly on the body fat reduction and body weight loss.

Furthermore, significant improvements in blood lipid profiles, inflammatory markers and blood pressure were observed.


Our clinical study demonstrated an increase in the daily energy expenditure rate of 400 kcal, supporting several aspects of weight management.


    Weight loss
  • Increases metabolic efficiency
  • Suppresses lipid accumulation
  • Reduces body and liver fat
  • Improves inflammatory markers
  • Helps regulating blood pressure

Where the story began

Native to the coasts of the northwest Pacific Ocean, Undaria pinnatifida– otherwise known as wakame – is a brown seaweed containing the xanthophyll fucoxanthin, which has shown to help burn fatty tissue.

Originating from the Himalayas in northern India, Punica granatum (pomegranate) is being cultivated throughout the Mediterranean region. Pomegranate seed oil is rich in antioxidants and polyphenols and is known to lower cholesterol.

Xanthigen® combines the benefits of fucoxanthin with those of pomegranate seed oil to a unique patent-protected weight management product.

Low dose allows consumers to integrate Xanthigen® into daily routine


What sets us apart?

Pre-clinical studies demonstrate Xanthigen®‘s mechanism of action. It prevents new lipid formations by inactivating key proteins involved in fatty acid and colesterol synthesis. Xanthigen® promotes the fatty acid breakdown via inactivation of AMPK, a protein involved in the energy metabolism and supression of fat cells generation (adipogenesis).

It was furthermore demonstrated, that at the metabolic level Xanthigen® improves liver function and lowers the accumulation of liver fat. Basal-low levels of systemic inflammation were reduced, possibly leading to a positive effect on metabolic stress response. Additionally, a reduction in blood pressure was confirmed, an effect closely associated with anti-obesity properties.

Our science

Our peer-reviewed, double-blind, placebo-controlled human clinical trial included 151 participants, receiving a hypocaloric diet for 16 weeks and 600 mg of Xanthigen® per day. The results showed an increase in daily energy expenditure rate of 400 calories and a weight loss of 6% to 7% of the body weight baseline compared to the subjects treated with placebo.

In addition, subjects consuming Xanthigen® showed a notable reduction in liver fat and adipocyte tissue fat mass, leading to the improvement on body composition.

The low dose of Xanthigen® required to obtain weight loss makes it easy for consumers to integrate it into their daily lives, helping them to achieve their weight management objectives.


Xanthigen® is a unique product, a blend of two botanicals known for their possible effect on weight loss. We carefully combined what nature knows best and have put it into an optimal combination for consumers to experience additional synergistic effects, supplementing their diet.

We are privileged that in a product category known for its short life-cycle, Xanthigen® has been successfully in the market for over a decade. And its success continues.
