Natural Support for Digestion & Metabolism

Over time, metabolism can change due to age, environment, and daily habits. Even with a balanced diet and regular movement, digestion and fat metabolism may benefit from additional support.

Just Björn Marine Chitosan is an advanced natural fiber formulation with LipoSan Ultra®—a more refined, bioavailable form of marine chitosan sourced from wild-caught shrimp. Designed to work naturally with meals, it supports digestion, healthy metabolism, and cardiovascular health, while helping regulate appetite and support sustained energy.

Why Marine chitosan
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.

Frequently asked questions

What is chitosan?

Just Björn Marine Chitosan is a natural fiber supplement sourced from the shells of shrimp. When taken with food, it binds to dietary fats in the stomach to support metabolism and cardiovascular health (cholesterol and glucose levels), regulate appetite, enhance the body’s fat burning ability, and boost energy levels.

How do I take chitosan?

We recommend taking just björn marine chitosan twice daily with water, just before or during a meal. For best results, pair with a balanced diet and active lifestyle.

How is just björn chitosan different?

We use LipoSan Ultra®—a patented, fast-acting form of chitosan with superior fat-binding capacity. It’s water-soluble, clinically studied, and more effective than standard chitosan. That means better results with a smaller dose.

Can I take chitosan with other supplements, like marine collagen?

Yes. Chitosan works well with marine collagen and most supplements—just avoid taking it at the same time as fat-soluble vitamins (A, D, E and K), medications, and oil supplements. These should be taken at least 4 hours before or after ingestion of Chitosan to ensure absorption.

Is chitosan safe for people with shellfish allergies?

Testing has shown no allergenic reaction to Chitosan including people with fish and shellfish allergies. If allergic to shellfish, we recommend consulting with your doctor before taking chitosan.

Excited to receive my starter kit and honestly noticed a difference very quickly! I feel balanced

Excited to receive my starter kit and honestly noticed a difference very quickly! I feel balanced, and somehow lighter - and less hungry. The capsules are small, easy to swallow, so super simple to add to my routine. I think taking them at mealtimes also makes me mindful of eating healthier.

Dear Julie—thank you for sharing your experience. I’m glad to hear our Marine Chitosan has been easy to incorporate into your routine and that you noticed a difference so quickly. Taking it consistently alongside meals can be a great way to support mindful eating habits and overall wellness over time. B your best, Björn

I found this product to be very effective

Why I stopped taking Chitosan.

Let me first explain that I stay well hydrated ( over 2 liters a day) all throughout the day, and I eat a lot of fruits and vegetables daily. Taking two capsules twice a day caused terrible constipation, so I dropped down to one capsule twice a day and still experienced constant constipation. Next, I tried one capsule once a day and was still constipated. Now I have stopped taking chitosan and am no longer constipated.

Dear Maryanne,

I'm truly sorry to hear that our marine chitosan wasn't the right fit for you. While many people tolerate chitosan well, everyone's digestive system responds differently to added dietary fiber, and some individuals may experience temporary constipation as their body adjusts. Increasing water intake and staying active often helps during that adjustment period, but it sounds like even with reducing your dosage and staying well hydrated and that wasn’t your experience.

Your health and comfort are always more important than continuing any supplement. Thank you for sharing your honest feedback—it helps others make informed decisions and we appreciate you giving our marine chitosan a try.

Warm regards,
Björn

Feeling more in balance

I just started using Just Bjorn Marine Chitosan and have been really liking it so far. I’ve noticed less bloating and feel fuller longer between meals. It’s also super easy to work into my daily routine. Overall I feel more in balance.

Dear Heather—thank you for sharing. Supporting digestion and overall balance in a simple, consistent way is exactly why I created our Marine Chitosan. B your best, Björn

Great Product

I’ve been taking Marine Chitosan for a few days, and I’ve noticed I feel fuller after meals and don’t get hungry as early—especially by lunchtime. It’s been really easy to add to my routine, and I’m looking forward to seeing how it supports me over time.

Dear Dan,

Thank you for being one of the first to share your experience with our Marine Chitosan—it means a lot. I’m glad to hear it’s been easy to incorporate and that you’re already noticing a difference. I look forward to hearing how it continues to support you over time.

B your best,
Björn
