why choose marine chitosan

just björn marine chitosan with LipoSan Ultra® is an advanced natural fiber formulation with superior fat binding capacity. It helps support digestion and metabolism, cardiovascular health (cholesterol and glucose levels), and appetite regulation, enhances the body’s fat burning ability, and boosts energy levels. This powerful antioxidant is extracted from the shells of wild-caught shrimp from pristine North Atlantic and Arctic waters, and like our collagen, is part of the circular economy.

bioactive formula supports digestion and metabolism

Aging and environmental factors can contribute to metabolic changes which can have a negative impact on the body. Even with a healthy diet and regular exercise, our metabolism can slow, making it more difficult to manage and maintain a healthy weight. Our Marine Chitosan optimizes the metabolization of fat naturally, reducing the absorption of dietary fat when taken with a meal.

Just Björn Marine Chitosan is made in Iceland with LipoSan Ultra® a proprietary dietary fiber formulation that is highly soluble with enhanced fat-binding capabilities. It has a positive effect on intestinal flora, contributing to improved digestion, and binds to fat ingested from food, reducing its absorption in the digestive tract. Just take 2 capsules twice a day with a meal and feel the benefits as soon as your first dose. The plant-based capsules are small, easy to swallow, odorless and flavorless.

The benefits of chitosan

nordic supplements to help you b your best

  • Supports digestion and metabolism as part of a balanced daily routine
  • Supports appetite regulation and promotes a natural feeling of fullness as part of a balanced daily routine
  • Supports cardiovascular health by helping manage dietary fat as part of everyday meals
  • Supports healthy weight management as part of an active, balanced lifestyle
  • Supports healthy aging by promoting metabolic and digestive wellness as part of daily nutrition
  • Digestion and Metabolism
    Supports healthy digestion and metabolism
    Chitosan helps maintain a healthy balance of gut bacteria, which is essential for optimal digestion, nutrient absorption, and overall gut health. As a fiber, chitosan can support digestive health by promoting regular bowel movements.
  • Appetite Regulation
    Manages cravings and promotes a feeling of fullness
    Chitosan provides a sense of satiety, expanding in the stomach which can slow the rate at which food moves through the digestive tract. This can make it easier to control food intake by curbing hunger and avoiding overeating.
  • Cardiovascular Health
    Supports healthy cholesterol and glucose levels
    Studies have shown the ability of Chitosan to help lower levels of cholesterol by binding fats and help regulate blood sugar by slowing carbohydrate absorption. Our Marine Chitosan can reduce the absorption of cholesterol from food, leading to a healthier lipid profile.
  • Weight Management
    Reduces fat absorption and contributes to weight loss
    Chitosan binds to dietary fats and prevents their absorption in the digestive tract to support weight management and overall metabolic function. This reduces the amount of fat the body absorbs and the strain on the digestive system from excess fat.
  • Healthy Aging
    Provides antioxidant and anti-inflammatory benefits
    Chitosan, with the addition of Vitamin C, provides antioxidant effects that can help neutralize free radicals, protecting cells and tissues from oxidative damage. Reduction of oxidative stress may help slow down the aging process.

Turning Waste into Wellness

This Marine Chitosan formula is 100% sustainably sourced. We utilize the shells of shrimp from the North Atlantic and Arctic waters, which are typically discarded. Just as with our marine collagen, we can take something once considered waste, and harness its beneficial, nourishing properties to promote good health, naturally.

The Icelandic government strictly regulates the use of marine resources to ensure sustainable management, helping to maintain a balanced marine environment. The combination of quality raw materials from pristine waters, and a unique processing technology, allows just björn to offer the purest and most effective chitosan on the market.
