What is Ultimate Cleanse?

Ultimate Cleanse product is not just a digestive health product that will clean your colon. It is equipped with ingredients that will promote your overall well-being. Most of the ingredients used are not new in this field. They have been subjected to many clinical studies and proven to promote digestive health in one way or another. The ingredients have been divided into two basic parts, making the product some kind of an all-inclusive program toward joint health.

The first part is a blended fiber-cleanse part that is specially designed and formulated for people with bowel movements. This part contains ingredients that are high in fiber, which plays an important role in binding with stool such that the stool adopts a texture that can comfortably be flushed out of the body. This first part plays a critical role in ensuring that the user doesn’t suffer from constipation or diarrhea. Although the official website doesn’t mention this, we believe that it has the capabilities.

The second part is formulated by blending several herbs that are fasting against parasites and flushing out harmful toxins and waste. Although the second part doesn’t target all the seven organs responsible for excretion in the body, it sure does cover most of them. In fact, this blend of ingredients may have a positive impact on other organs of excretion. The second part also contains shellfish, which you have perhaps heard about in joint-related supplements. Shellfish is harvested from fish and thus is a rich source of minerals and oils.

How Does This Work?

Ultimate Cleanse works by flushing out harmful parasites and aiding the body to remove the waste product of metabolism. There are several waste products that arise during metabolism. Most of the waste product list is in the form of water and can be lost through all seven channels of excretion. The bulk of the waste product, however, passes through the digestive system. With this in mind, we can conclude that the digestive product has an immense role when it comes to getting rid of body waste.

Ultimate Cleanse is highly fibrous, and this allows for ingested food to be bound together and removed from a stool. The fibrous nature of the Ultimate Cleanse guarantees you a good stool texture that can be easily gotten rid of. Lack of fiber in our diet can result in loose stool or constipation.

The herbal blend ingredients do all the other donkey work. Most importantly is to rid the body of parasites and harmful bacteria. This is achieved by creating an internal environment in which these parasites cannot survive in.

Ultimate Cleanse Ingredients – Are They Safe and Effective?

Oat Bran

– One of the most noticeable elements in oat bran, which is bursting with them, is fibre. The body is unable to digest fiber, a form of carbohydrate. Even while it could seem like an issue, this really benefits your body’s digestive system[1].


– Fennel has been demonstrated to aid in digestion by lowering gut inflammation and gas-causing germs. Fennel oils may also help to reduce the signs and symptoms of irritable bowel syndrome, according to one study[2].

Alfalfa powder

– Better bowel movements and constipation can be caused by alfalfa seeds. They also aid in the reduction of other conditions like flatulence, acid reflux, gas, and bloating. Alfalfa sprouts work to balance the stomach’s acidity and stop acid reflux[3].

Cascara Sagrada bark

– Chemicals in cascara sagrada stimulate the intestines and have laxative effects. Cascara sagrada is used for a variety of ailments, including constipation, emptying the colon before to a colonoscopy, and others, however, there isn’t any solid scientific proof to back these claims[4].

Q: What Are the Claims Made by the Manufacturer?

A: Ultimate Cleanse makes a strong claim that it gets rid of waste. As a clarification, it is good to note that this product cannot revive and already cripple the digestive system. The product is not some kind of dialysis. Ultimate Cleanse supports the organs by flushing out the waste by nourishing them and protecting them from attack by a parasite. It doesn’t in a way heal or repair a damaged organ.

For this reason, it cannot be used as an alternative to an already collapsed organ. For the best reason, we should adopt healthy living by avoiding drugs such as alcohol and cigarette, taking loads of water, eating well, and exercising.

Q: What Are The Side Effects Of Ultimate Cleanse?

A: As of now there have been no side effects reported by users who have used the Ultimate Cleanse. But some negative reviews are mentioned on other e-commerce sites.

Q: How Quickly Does It Start Working?

A: This started working within a few days. Take one of each nightly and have for 5 years. Do it for maintenance, but not sure if that is appropriate for everyone. This was the only product that made the digestive system regular and predictable.

Q: Is Ultimate Cleanse Cruelty-Free?

A: Yes, the brand claim that it is a cruelty-free product.

Customers Reviews

Great for de-bloating and staying regular. Unaware it contains animal products.

I have taken this product for two days. I didn’t feel ANY discomfort or diarrhea, while still cleansing my body and debloating me. However, I am vegan and just now noticed this product contains shellfish and dairy. I’m a little grossed out and disappointed but that’s my fault for not double-checking the ingredients. I would love this product otherwise! Will be in search of a vegan alternative and give what’s left to a family member.

    Feeling better already! Amazing product!
    I started taking Ultimate Cleanse a few weeks ago and noticed an improvement to my digestion almost immediately. This has reduced bloating significantly as well as cramping and gas. My appetite seems to be under control too! Not necessarily less desire to eat food but my cravings to over indulge are totally gone – and I am a sugar addict binge eater!!! I have found it much, much easier to maintain a balanced and clean diet. I used this product several years ago and I wish I never stopped taking it. I plan to keep using Ultimate Cleanse long term for the digestive benefits alone! I highly recommend this product!
