Welcome to my Consti Slim review.  

Weight loss supplements can help those looking to lose those extra pounds. While nutrition and exercise might be enough for some people, there are some cases where cravings, appetite, and metabolism are working against you. 

As a Registered Dietitian, I’ve guided hundreds of clients toward their weight loss goals. During this journey, I’ve also helped them choose the best supplement to give them the extra support they need.

Consti Slim claims to aid weight loss by improving your gut health. Its unique blend of ingredients might help remove toxins and enhance digestion and bowel movements. 

Research does show a link between good gut health and weight loss. The bacteria we have can either promote or make it harder to drop pounds. 

However, the lack of third-party Consti Slim reviews and some clinically unproven ingredients creates some concerns. 

Let’s find out if Consti Slim is worth buying or better to avoid.

What is Consti Slim?

simple promise consti-slim

Simple Promise Consti-Slim is a weight management supplement.

It is made with natural ingredients reported to help detoxify your body, improve your digestion, regulate your bowel movements, and aid in maintaining a healthy weight.

The company states that custom ingredients, such as bentonite, psyllium husk, and aloe vera (to name a few), can help reduce bloating, constipation, and gas. 

Who is Consti Slim for?

Keep in mind that they don’t claim this to be a weight loss supplement. Instead, it’s marketed as one that can help in healthy weight management. 

Therefore, it’s probably not the first pick for someone with a lot of weight to lose. It’s more likely for those who feel that digestive issues are making them hang onto a few extra pounds.

Is Consti Slim Safe to take?

Yes, Consti Slim is safe to take since most ingredients have evidence to help back up their claims. 

However, since it is a proprietary blend, it doesn’t state how much of each ingredient they use. Thus, it is hard to determine if they use the proper doses for each component. 

Many supplement brands use proprietary blends and this doesn’t make them an effective product. It only doesn’t tell you the amount of one ingredient.

Things to Consider Before Buying Consti Slim

Consti Slim can be a good option to improve your gut health. However, there are some things you need to consider before buying this supplement. 

Weight Loss Supplement

Consti Slim can help improve your gut which indirectly can help you lose a couple of pounds. Its main focus is to help digestion and relieve constipation, which can lead to losing a couple of pounds. 

However, this is not the case if you are looking for a supplement to decrease your appetite or provide fat-burning properties. 

LeanBean is a great appetite suppressor and PhenQ has great fat-burning properties.

But if you have digestion issues and need a weight management supplement, Consti Slim is a better option.

Nutrition and Exercise

Consti Slim considerations

Consti Slim is a temporary fix. 

As long as you take the supplement, your digestive symptoms might improve. 

But, if you don’t make any lifestyle improvements and stop taking the supplement, you will likely return to your old symptoms. 

Make sure you’re consuming enough fiber. The daily recommendation of fiber is 20 to 30g of fiber daily. Drink plenty of water, and exercise regularly to have good bowel movements. 

Consti Slim Features 

Let’s talk about those features that make Consti Slim stand out from other gut improvement supplements. 

100% Natural Ingredients

One benefit of Consti Slim is that it uses all-natural ingredients. 

Studies have shown that consuming artificial ingredients might impact your gut microbiome. This can lead to an increase in bad bacteria, which can cause poor digestion and constipation. 

Additionally, some natural herbs and ingredients are frequently used in traditional medicine (dated way back). 

They include a custom blend of natural ingredients like aloe vera, cascara sagrada, and oat straw that can help reduce your symptoms. 

Gut Health

Nothing is more uncomfortable than having bloating, gas, and constipation throughout the day. You feel heavy and constricted, like your clothes don’t fit.

Thanks to its proprietary blend of probiotics and gentian, Simple Promise Consti-Slim can help improve gut microbiome health, leading to better digestion. 

This brings me to my next feature.  

Fights Constipation 

Consti Slim features

Nowadays, it is very common for people to have constipation. The decrease in fiber due to a highly processed diet can affect bowel movements. 

If you cannot go to the bathroom daily, you might think of taking a laxative. However, they often leave your stomach feeling worse. 

Plus, you cannot use them daily due to the risk of dehydration. 

Consti Slim contains several natural laxatives like cascara sagrada, rhubarb, aloe vera, and alfalfa to help you fight constipation without making your stomach upset. 

Does Consti Slim really work?

Yes, the ingredients can help promote gut health and fight constipation. 

However, remember that everyone has a different reaction to supplements. What might work for some people might not work for others. 

Since there are no third-party reviews, it’s difficult to determine how effective the supplement really is. 

How effective is Consti Slim?

How effective Consti Slim is for you depends on your reason for taking it.

Consti Slim is likely more effective as a gut balancer than a weight loss supplement. You might have some weight loss due to the evacuation of material, but it is not permanent weight loss. 

Consti Slim Ingredients

The company makes sure to use only natural ingredients. 

However, they don’t state how much of each ingredient they use. Since it’s a proprietary blend, we cannot compare if the doses are within the recommended amount. 

Here are all the ingredients in Consti Slim:  

  • Calcium Carbonate
  • Bentonite
  • Oat Straw
  • Alfalfa
  • Psyllium Husk
  • Rhubarb
  • Gentian
  • Aloe Vera
  • Cascara Sagrada
  • Goldenseal Root Extract
  • Buckthorn
  • Lactobacillus acidophilus

Calcium Carbonate (200 mg)

Calcium carbonate is a type of calcium used to increase calcium absorption. Low calcium levels can lead to weak bones, leading to osteoporosis. 

It’s also often used as an antacid to prevent heartburn, reflux, and indigestion


Bentonite is a clay that might help reduce toxic waste. 

Studies show that consuming bentonite can absorb toxic materials like heavy metals and pesticides. It can also nurture the body by providing essential nutrients like iron, calcium, and copper. 

Nonetheless, there is still little research regarding this ingredient. 

Oat Straw Extract

consti slim ingredients

Oat straw extract comes from the unripened oatmeal plant. 

It’s high in fiber which can help fight constipation. Also, thanks to its high fiber content, it has weight-loss properties. 

Research shows that fiber can help increase your fullness levels which leads to less snacking throughout the day. 

Also, it is high in antioxidants, which can help reduce inflammation and help promote good gut health. 


Alfalfa is a plant with great benefits. 

One of the benefits of alfalfa is that due to its saponin content, it can help decrease cholesterol levels. It helps modulate the gut microbiome to increase cholesterol absorption. 

Additionally, it can help decrease glucose and blood pressure levels. 

Finally, it is a powerful antioxidant that can help reduce inflammation.

However, most are animal studies. There is still more research needed to determine the health benefits of alfalfa. 

Psyllium Husk

simple promise consti-slim ingredients

Psyllium husk is a type of fiber from the Plantago psyllium plant. 

It’s a natural laxative often used to help fight constipation. It helps absorb water, forming a gel that helps normalize bowel function.

Also, it can improve heart health. Research shows that consuming psyllium husk can help reduce cholesterol levels. 

Recommended dosage: 5 to 30 g


Rhubarb is a plant similar to celery. 

It’s very high in fiber. This can help fight constipation and reduce cholesterol levels. 

In fact, a study showed that men who consumed at least 27 g of rhubarb for four weeks had a reduction of 8% in their cholesterol levels. 

It is also high in antioxidants which can help reduce inflammation. 


Gentian root is a plant with medicinal purposes.

Most people use it to treat digestive issues like bloating, gas, upset stomach, and nausea. 

However, it can also increase appetite. In a study, children with anorexia were supplemented with gentian to help increase hunger. 

Still, there is a lack of evidence in human studies. 

Aloe Vera

consti slim reviews

Aloe vera is a natural laxative. 

Research shows that ingesting aloe vera can help fight constipation. Additionally, it seems that it can help reduce heartburn and reflux symptoms. 

Recommended dosage: 600 mg (but there is still little research to determine the right dosage)

Cascara Sagrada

Cascara sagrada is a bark that serves as a natural laxative remedy. It works by increasing your intestine’s motility. 

However, in 2002, it was banned by the FDA due to a lack of evidence and classified as not safe. 

While you can still buy it as a component in a blend (like Consti Slim), you can not buy it on its own as a natural laxative. 

Recommended dosage: 100 to 300 mg (dried bark extract)

Goldenseal Root Extract

consti-slim reviews

Goldenseal root extract is another common medicinal plant. 

It is a powerful antioxidant that can help reduce inflammation and promote good gut health. 

Research shows that combined with Echinacea, it can help reduce the symptoms of the common cold. 

Additionally, it seems to have positive effects on fighting urinary tract infections


Buckthorn bark is a common remedy to fight constipation

However, there is still more research to help determine other health benefits from this ingredient. 

Lactobacillus acidophilus

Lactobacillus acidophilus is one of the most common probiotics on the market. 

It can help promote good gut health by increasing the number of healthy bacteria in your intestines. 

Also, it can help decrease the symptoms of irritable bowel syndrome and diarrhea. 

Finally, it might help promote weight loss, but most research is limited to animal studies.

How To Use Consti Slim

The company recommends consuming two capsules one to two times daily with food. 

Recommended Dosage

I recommend consuming only two capsules per day to determine if you get any possible side effects. If it is not working, you can increase it to four tablets per day (two capsules twice a day).

“I have suffered from constipation my entire life. A doctor recommended bentonite clay. I tried it alone and it didn’t really help so I tried Consti-Slim. I took it faithfully everyday and started seeing results around 2 months. Now I have a bowel movement every 2 or 3 days so it works. I will continue taking it daily and recommend that you try it!”

Health Benefits of Consti Slim

There are several potential health benefits of taking Consti Slim, like:

  • Weight loss
  • Digestive functions improvement
  • Immune system support
  • Inflammation reduction

Weight Loss

consti slim benefits

Consti Slim is not a weight loss supplement. However, thanks to its high-fiber ingredients like rhubarb, psyllium husk, Cascara sagrada, and oat straw extract, it can increase your fullness levels. 

A decrease in your appetite leads to a reduction in snacking and smaller portions. This can help create a caloric deficit, which leads to weight loss. 

Digestive Functions

This supplement can aid in digestive functions. Ingredients like probiotics (Lactobacillus acidophilus) and gentian can help boost your digestive function.  

Immune System Supports

Research shows that better gut health can lead to a healthier immune system. Your gut microbiome is called the second brain. It helps modulate certain hormones and can boost your immune system. 

Inflammation Reduction

Consti Slim provides several antioxidants. These molecules (antioxidants) help reduce the damage done by free radicals (unstable molecules that can increase inflammation). 

Inflammation is thought to be linked to the onset or progression of many diseases.

Ingredients such as goldenseal root extract, rhubarb, and alfalfa all help decrease inflammation. 

Potential Side Effects of Consti Slim

Consti Slim side effects might include stomach cramps, diarrhea, bloating, and gas. This can happen during the first couple of days as you get used to it. 

It’s always best to speak to your doctor before taking any new supplement. You should also call your doctor if any negative side effects last more than a day or two.

Consti Slim Price

One bottle of Consti Slim has a price of $49. This can last up to one month if you use two capsules daily. 

Consti Slim Shipping and Returns

The company offers free shipping to the US. International orders might take 10 to 14 days.

Regarding the return policy, you can return it unopened to the company. If you want to learn more about their return policies, visit their FAQ page.

Final Recommendations

We are at the end of my Consti-Slim review. 

Consti Slim seems like a very good supplement to help improve your gut health. It can help you improve the gut microbiome and fight constipation. 

Nonetheless, you need to make lifestyle changes. Add more fiber to your diet, including more fruits, vegetables, and whole grains. 

If you do use this supplement, make sure to drink plenty of water to avoid any possible dehydration. 

Also, make sure not to use it for more than one month. Take a break, and then you can use it again in a couple of months. 

Consti Slim seems like a supplement worth trying, as long as you’re not looking for major weight loss. The lack of third-party reviews is concerning, but some of the ingredients are good for getting things moving.

Head over to their website if you are ready to make your first purchase, and let me know what you think if you’ve tried it.
