ChitoLean (pronounced CHIT-uh-lean)

Key Benefits
- Helps improve body composition.
- Binds and blocks dietary fat from absorption when taken with high-fat meals.
- Powerfully assists fat burning and oxidation.
- Promotes healthy bowel movements.
Backed by our 100% Quality Satisfaction Guarantee.
How It Works
ChitoLean combines three key nutrients. Think of it as: bind what you don’t want + burn what you can use.
- Chitosan (a non-digestible fiber) travels through the GI tract and binds dietary fat, helping block absorption.
- Vitamin C activates chitosan into a more effective fat-binding gel in the stomach and intestine.
- N-Acetyl-L-Carnitine supports fat oxidation by helping transport fatty acids into cells for energy.
Who Should Use ChitoLean?
Ideal for:
- People who eat well most of the time but occasionally face high-fat meals (restaurants, travel, social events).
- Anyone working on weight loss or body composition who wants support when diet isn’t perfectly controllable.
- Those supporting cholesterol and arterial health as part of a broader healthy lifestyle.
- People who want help with regularity when meals get heavier than usual.
Not for / check first:
- Shellfish allergy — chitosan is derived from shellfish. Do not use.
- If pregnant, nursing, on medication, or managing a condition — consult your healthcare professional first.
- If relying on fat-soluble vitamins (A, D, E, K) or specific medications, follow the spacing guidance below.
Dosage
Take 3 capsules shortly after beginning a high-fat meal. Drink 8+ oz of water with each dose.
Spacing rule (critical): Take healthy fats (e.g. fish oil), fat-soluble vitamins (A, D, E, K), and medications 4+ hours before or after ChitoLean.
Ingredient Breakdown
Chitosan — A fiber derived from chitin (shellfish) with a strong positive charge that binds negatively charged dietary fat, helping block absorption. Also supports cholesterol normalisation and may inhibit atherosclerotic plaque formation as part of a healthy lifestyle.
N-Acetyl-L-Carnitine — Supports fat burning by transporting fatty acids into cells for energy production. Carnitine can be depleted by exercise and tends to decline with age.
Vitamin C — Activates chitosan into a more effective fat-binding gel. Research shows increased fecal fat excretion when vitamin C is paired with chitosan.

Let customers speak for us
Extremely useful to use whilst cycling, removes the faff of opening gels whilst cycling and the solid bottle makes it easy to get in / out of jersey pockets.
Brilliant product - i use these in all my endurance events - some lasting up to 20 hours. These are great to ensure you get the required electrolytes without over hydrating.
Great service and the products are amazing, especially for endurance sports. I'm a big fan of the Endrolytes Electrolyte Caps. Their magnesium supplement and vitamin D are also very very good! I would highly recommend.
I’ve used Hammer products for around 6 years now & my favourite by a mile is the hammer Perpetuem, it’s fueled my last 100 mile ultra marathon not to mention multiple long distance triathlon's . It has 180calories per serving and it’s 34g of carbs & 5g of protein seems to work well . I’d strongly recommend for anyone who wants to take on ultra races as this fuel will support you when you need it most .
I started using Hammer Heed and Perpetuem 5 years ago and it's been such a game changer for my. Finding nutrition you can trust is so important for any athlete and I highly recommend Hammer Nutrition for any distance and any sport.
I couldnt race without hammer products. Heed is my favourite, such an amazing product. Paired with the gels it makes a great fueling recipe. Always fast shipping
Wonderful product for general Well being and Recovery. Great quick shipping.
Love all your products. I personally will concentrate on the perpetuum for my long swim(45km) as it feels like a meal every 4mins.
Thank you
great taste! great weight to calorie ratio! thanks
Great quality feel and easy to drink from whilst riding.
No plastic smells either.
Just need a few different colours?
Help me through a 70 miler. Would recommend 👌
