ProbioSlim Ingredients – The Science Behind Force Factor ProbioSlim
It is first important to know what is in this supplement and what role they play in either weight loss or digestive health (the two main claims made by the manufacturers of ProbioSlim). Take a look at what we found:
LactoSpore – This is the “revolutionary” probiotic that is in ProbioSlim to help maintain healthy gut function. Everyone has a certain amount of bacteria in their gastrointestinal tract, and maintaining a healthy b can be delicate; LactoSpore aims to achieve this balance.
Green Tea Leaf Extract – Green tea leaf may help the user lose weight. Consumer Health Reports elaborates on this claim. They state that due to the caffeine and catechins in green tea leaf extract, the metabolic rate may be affected. They do admit that these effects are minimal.
Prebiotic fruit Extract – We are told on the Force Factor website that this fruit complex includes kiwi, fig, and papaya. Prebiotics may play a role in weight loss by promoting the health of the microbiota of the gastrointestinal system.

The leading theory behind the link between gut bacteria and weight loss comes from an observed difference between the gut bacteria of slim people and those who are obese. This is still a theoretical link, though.

Will ProBioSlim Really Work?
How long does it take for ProBioSlim to work?
The answer to this question depends on what you want it to work for. Let’s take a look at the facts about the ingredients. LactoSpore is a probiotic. Probiotics have traditionally been used to help digestive issues, and this one is no different, so it may help with symptoms like indigestion and loose stools.
Next is the fruit complex. These are considered prebiotics which also affects gut health by acting as food for probiotic bacteria. This Gastro Journal report, however, shows that when prebiotics were tested against a placebo group, there was little difference in weight or gut health.
Finally, there is a green tea leaf. This seems to be the only ingredient that would have any viable effect for weight loss due to its reported effect on metabolism. But, as we mentioned earlier, there have only been weak scientific findings that support this claim.
So will this supplement work? It would seem that ProbioSlim would be better suited to someone with gastrointestinal concerns than weight loss concerns.
The way that gut bacteria is said to have an effect on weight is the manner in which gut bacteria play a role in getting energy from calories, as per the Mayo Clinic. So the theory goes that if you have the right gut bacteria, you will burn caloric energy better. This, however, is still just a theory.

Possible ProBioSlim Side Effects
- Bloating
- Flatulence
- Upset stomach
Furthermore, there is caffeine (from the green tea leaf) in ProbioSlim, a natural stimulant that may also have negative side effects such as keeping you up at night or making you restless. This effect may be exacerbated if you are particularly sensitive to caffeine. Most of these symptoms are not long-lasting.
Final Thoughts on ProbioSlim Force Factor
Many people have reported positive results in their digestive health after taking this product, but few have reported any actual weight loss. This is a bit problematic because ProBioSlim is marketed as a weight-loss supplement. The word “slim” is literally in the name! There is weak evidence linking good gut bacteria and weight loss, so we are inclined to think that you would benefit more from other supplements if your goal is weight loss.
That said, we can’t knock ProbioSlim for its pre-and probiotic content; it seems to be pretty solid in that department. It is a bit pricey for a probiotic; there are plenty of alternatives that are cheaper and are probably just as effective. If you do try this product, be sure to keep in mind the 30-day refund policy and keep a close eye on how it is affecting you.
Causes upset stomach
I purchased ProbioSlim because I knew for a fact that I do not consume enough fruits and vegetables and was probably deficient in some of the important nutrients they deliver. Unfortunately, this product does not seem like the right option for me. I have taken these types of probiotics before but have never experienced the upset stomach and discomfort this one causes for me. I am not sure why it happens, but I have tested it multiple times and it always ends the same. If you have a sensitive stomach this is probably making you miserable. Check out other options.
Wonderful product that actually works
I have always suffered from chronic constipation and after age 50 the bloating and gas I experienced were beginning to affect my daily life. After starting ProbioSlim within a few weeks I noticed a drastic reduction in the daily abdominal symptoms. I am noticing a reduction in the size of my abdomen and a return to a more youthful contour.
Its working for me little by little
I do like the product and I see it working little by little. I will continue to which what I eat so I am developing good eating habits.
This has worked well for me. No reactions to the product
I wanted to lose 6-10 pounds in addition to what I have already lost, this is helping me achieve that goal.
