Gut Bomb 350 Billion: How Probiotics Can Help You Lose Weight

YouTube video

Gut Bomb 350 Billion is my #1 most popular probiotic because it is designed specifically to help provide your body with an intense dose of probiotics to help support your metabolism, help restore normal gut function, balance your hormones (especially thyroid hormone), and help you lose weight if used as a part of a comprehensive weight loss program/regimen.

Gut Bomb 350 Billion is so effective because it provides your dose with a very large dose of probiotics (350 billion to be exact) with each serving. Most probiotics are not effective weight loss tools because they don’t contain high enough doses.

Gut Bomb, on the other hand, provides your body with 23.3x the average probiotic dose from other brands of probiotics (the average dose of probiotics is around 15 billion CFU). Each sachet of Gut Bomb is formulated with over 600 billion CFU of probiotics to ensure that each packet you consume contains at least 350 billion CFU of probiotics.

Not only does it contain a massive dose of probiotics in each serving (I call it Gut Bomb for a reason), but it also provides a wide range of probiotic diversity with over 18 different species and strains. You might be able to find high-dose probiotics but you will be hard-pressed to find probiotics that contain a wide variety of probiotics.

But this isn’t all that Gut Bomb can help with.

Gut Bomb can also help support the following areas:

  • Immune function
  • Hormone Balance (Estrogen + Progesterone)
  • Thyroid hormone balance
  • Balance your mood
  • Balance Gut dysfunction
  • Treat SIBO and yeast overgrowth
  • Reduce inflammation
  • Balance stomach acid levels
  • Support therapies for treating autoimmune conditions
  • Reduce the number of bad calories that you absorb
  • Regulate bowel movements
  • Improve nutrient absorption from food and other supplements
  • And more…

And that’s just the beginning…

Should you be taking probiotics?

Great question and the answer is almost invariably yes.

Almost every aspect of your life has some effect (positive or negative) on the bacterial concentration in your gut.

Want to eat some ice cream? You’re promoting the growth of BAD bacteria.

Are you under a lot of stress from work? Your stress is killing off good bacteria.

Have hypothyroidism or other hormone problems? These imbalances change your microbiome.

Don’t want to work out because you are tired? Not working out promotes unhealthy bacterial levels.

The list goes on and on.

Basically, every action you take is either promoting healthy bacterial growth or helping promote unhealthy bacterial growth in a tug-of-war fashion.

A high-quality, multi-dose, multi-strain probiotic is a great way for you to fight back against the normal everyday stressors of your life.

They can help promote the healthy growth of bacteria while killing off the negative bacteria – it’s a win-win.

And that’s not all they do – taking probiotics may actually promote some other very beneficial side effects such as weight loss…

Probiotics & Weight Loss

It might surprise you to know that probiotics can actually have a dramatic effect on your weight and metabolism.

Why does this occur?

It has to do with how probiotics, and your gut, influence your hormones, how many calories you are absorbing, your appetite/cravings, and how these influence your fat-storing hormones.

#1. Probiotics may alter intestinal bacteria and help REDUCE the total number of calories that you absorb with each meal.

Did you know that the amount of calories you absorb from each meal depends on the type of bacteria in your gut?

Unhealthy proportions of gut bacteria promote INCREASED absorption of calories.

This means that two people (1 person with healthy gut bacteria and 1 person with unhealthy gut bacteria) can consume 100 calories of food, and the person with the unhealthy gut bacteria may absorb 90 of those 100 calories while the person with the healthy gut bacteria may only absorb 70 of those 100 calories.

With this in mind, you can alter the number of calories you absorb by improving your microbiome.

#2. Probiotics may help alter your appetite and help reduce cravings for unhealthy foods.

Does it feel like you have cravings for unhealthy foods, fatty foods, or sugary foods?

If so, it might surprise you to know that the population of certain bacteria in your gut may be the source of these food cravings.

This is how it works:

When you eat unhealthy food you are promoting the replication of unhealthy bacteria in your gut (this could be from eating ice cream, refined sugar, soda/diet soda, etc.).

As the unhealthy bacteria grow they begin to secrete cytokines into your bloodstream that alter neurotransmitter levels and increase your cravings for certain foods.

They do this because THEY survive off of the unhealthy foods they are eating, which means you have to keep eating those types of food in order to help keep them alive.

The more unhealthy foods that you consume the more they grow and the more they promote the eating of those unhealthy foods.

A vicious cycle.

You can break this cycle by creating an environment where healthy bacteria can thrive and that’s where probiotics step in.

#3. Directly influence and lower “fat-storing” hormones such as insulin while improving thyroid hormone which is involved in regulating your metabolism.

Lastly, and probably most importantly, the bacteria in your gut influence certain “fat-storing” hormones such as leptin and insulin.

It has been well established through various studies that the environment of your GI tract may promote the development of a condition known as metabolic syndrome.

Metabolic syndrome is a constellation of conditions that results in increased inflammation in the entire body, increased fat deposits in the belly, bad cholesterol, and high triglycerides.

This combination of diseases plays a significant role in your risk of developing serious conditions such as heart attacks, stroke, and cancer.

But it also promotes weight gain and weight loss resistance!

Taking high-dose probiotics (such as those found in Gut Bomb) can help kick-start your body and help, if used along with other therapies, to prevent these conditions.

Strains and Species in Gut Bomb 350 Billion

Gut Bomb contains 18 species and strains that have been clinically shown in studies to be effective (see studies below).

The complete list of strains, species, and concentrations of each is listed below:

  1. + Lactobacillus acidophilus La-14, 125 billion CFU
  2. + Bifidobacterium lactic Bl-04
  3. + Lactobacillus bulgaricus Lb-87, 5 Billion CFU
  4. + Bifidobacterium longum subsp. infantis Bi-26, 5 Billion CFU
  5. + HOWARU Bifido (Bifidobacterium lactis HN019), 25 Billion CFU
  6. + Lactobacillus plantarum Lp-115, 20 Billion CFU
  7. + Bifidobacterium longum Bl-05, 5 Billion CFU
  8. + Bifidobacterium bifidum Bb-06, 5 Billion CFU
  9. + HOWARU Rhamnosus (Lactobacillus rhamnosus HN001,) 15 Billion CFU
  10. + Lactobacillus rhamnosus Lr-32, 5 Billion CFU
  11. + Lactobacillus brevis Lbr-35, 5 Billion CFU
  12. + Lactobacillus gasseri Lg-36, 5 Billion CFU
  13. + Lactobacillus casei Lc-11, 5 Billion CFU
  14. + Lactobacillus salivarus Ls-33, 5 Billion CFU
  15. + Bifidobacterium breve Bb-03, 5 Billion CFU
  16. + Lactococcus lactis Ll-23, 5 Billion CFU
  17. + Streptococcus thermophilus St-21, 5 Billion CFU
  18. + Bifidobacterium bifidum, 5 Billion CFU

The relative concentration of probiotics is broken down to a unit known as CFU which stands for colony-forming units.

Like other supplements, the CFU is a good indicator of how “strong” or how “effective” your probiotic supplement will be.

Just going to the grocery store and purchasing a random probiotic will most likely NOT be effective unless the potency reaches a critical point.

Otherwise, you risk not putting enough of the probiotic into your body to make a difference.

This concept holds true for other supplements and medications and is why we have ‘therapeutic dose ranges’.

For instance:

Taking a supplement which has 10+ strains but only 5 billion CFU in each serving will likely NOT result in significant weight loss for you.

Compare that to most studies which use anywhere from 300 billion CFU up to 900 billion CFU per serving in the setting of weight loss.

With the average probiotic dose around 15-20 billion CFU per serving, these studied concentrations contain up to 20 to 60x higher doses and are largely the reason why they are so much more effective.

Bottom line?

Dosing (CFU per serving) makes a big difference in weight loss and is one of the reasons that Gut Bomb is so effective.

Why is Gut Bomb 350 Billion So Effective?

We’ve already hit on many of these points but it’s worth expanding on what makes certain probiotics better than others.

For starters:

Point #1: Gut bomb contains all 4 of the most well-studied probiotics that have been clinically shown to help with weight loss:

  • Lactobacillus gasseri
  • Lactobacillus rhamnosus
  • Bifidobacterium lactis
  • Lactobacillus casei


Only certain probiotics have been proven through clinical studies to help with weight loss.

This probiotic contains all of those species and strains in the amounts necessary to impact your gut health and promote a healthy metabolism.

Point #2: Gut Bomb comes climate controlled.

ALL probiotics will slowly die over time until they are consumed and used in your body.

The rate at which these little guys die depends on a number of different factors.

Factors such as how much light they are exposed to, how much moisture they are exposed to, and whether or not they are refrigerated can all impact how many bacteria survive.

*Certain probiotics need to be refrigerated and sheltered from the cold in order to survive. Gut Bomb does NOT need to be refrigerated and is considered to be a heat-stable probiotic (not all probiotics fit this designation).

If you don’t take care of the probiotics with packaging and manufacturing then they may die in transit and result in you taking a much lower dose of probiotics than you believe you are getting.

To prevent these issues, Gut Bomb 350 Billion comes packaged in a sachet that protects it from light and moisture. It is also formulated with over 650 billion CFU per serving of probiotics to ensure that by the time you take it you will be getting at LEAST 350 billion CFU per serving.

Point #3: Each packet is sheltered from light and moisture.

Gut bomb 350 billion comes in a foil-lined individual packet which is sealed and protects the probiotics on the inside from light and moisture.

Point #4: Contains temperature-controlled probiotics that will last during transit.

The probiotic species inside gut bomb 350 billion do not need to be refrigerated.

This helps ensure that you will get the maximum dose of CFU by the time it arrives at your door.

Point #5: Contains 300+ Billion CFU in each serving.

Very few commercial probiotics contain dosages as high as 300+ billion CFU per serving.

Please see the information above regarding why this is so important.

Tips for Using Gut Bomb for Weight Loss

As our number 1 probiotic seller, we constantly receive questions about how to use Gut Bomb for weight loss.

While Gut Bomb can potentially help you with your weight loss efforts it is by no means a miracle supplement.

For best results, I recommend that you use it in combination with other weight loss therapies. This will enhance the effectiveness of the supplement and also help you in many other ways!

Gut Bomb is a part of my weight loss guide (in the supplement section) but it can also be used with the following therapies:

#1. Use Gut Bomb 350 Billion daily x15-30 days (depending on how much weight you have to lose). I have personally taken up to 1 trillion (the equivalent of 3 Gut Bombs each day) to help support gut function. We recommend at least 1 sachet of Gut Bomb each day if you are using it for weight loss.

#2. Combine gut bomb 350 billion with supplements designed to reduce inflammation and increase thyroid function. Other supplements, especially protein powders, can help make Gut Bomb more effective.

#3. Add fermented foods/vegetables to your diet each day while using this probiotic. Eating fermented vegetables will help Gut Bomb populate your intestinal tract with healthy bacteria which all support metabolism.

#4. Combine gut bomb 350 billion with exercise (emphasis on strength training) at least 1x per week for 20-30 minutes. Don’t forget to exercise, especially if you are trying to lose weight!

#5. Eat a healthy diet that is not calorie-restricted. Using a whole food diet will make Gut bomb more effective! Don’t neglect your diet.

#6. Add an intermittent fasting schedule to your regimen. Intermittent fasting will also help promote the growth of healthy bacteria and can be very effective for weight loss.

#7. Aim for 5-10 pounds of weight loss each month and be patient! (If you lose more than 5-10 pounds per month you risk worsening leptin resistance and regaining your weight back).

Frequently Asked Questions

Gut bomb 350 billion can be taken with or without food and at any time of the day. Rarely, some people may experience nausea if they consume Gut Bomb on an empty stomach. If this occurs then simply take Gut Bomb with a meal.

You can use Gut Bomb as instructed on the package in the following ways:

For weight loss –>

  • For weight loss, you will want to be more aggressive which means you will want to use a higher dose more frequently than in other conditions.
  • Start with using 1 Gut Bomb package DAILY for 15 days (this is considered a “round” of Gut Bomb).
  • After you finish one round you can either continue with more rounds (as necessary) or transition to an every other day schedule.
  • If you are using Gut Bomb for weight loss you should continue with 3-4 rounds over a 2 month period and follow up with maintenance dose (dosing every other day or every third day).
  • Ensure that you are using Gut Bomb with the other therapies listed above! This will maximize your weight loss results.

For regular bowel maintenance & gut health –>

  • If your intestinal health is in order then you can use the maintenance dose of Gut bomb 350 billion which is 1 packet every other day to every third day.
  • If you are just starting I recommend 1 packet daily x7 days then 1 packet every third day x21 days. This will allow you to stretch out your Gut Bomb usage over 1 month.

For intestinal issues (yeast overgrowth, SIBO, low stomach acid, GERD, etc.) –>

  • The use for other intestinal issues will depend on your body, but I recommend starting with 1 packet daily x7 days then 1 packet every third day x21 days.
  • From that point, you can continue with 1 packet every other to every third day (once your symptoms have improved).
  • If you are using Gut Bomb to treat SIBO or yeast overgrowth then it’s best to use it after you have undergone your kill phase with herbal or conventional antibiotics.

Gut bomb 350 billion is generally well tolerated.

Some people report mild nausea if they take gut bomb 350 billion on an empty stomach, but most patients tolerate the probiotic very well and only notice an improvement in symptoms.

For intestinal health, I recommend that you use the maintenance dose for 6 months to properly restore beneficial bacteria in your gut.

Solid product that works

This has given my husband a solid foundation for health. He has been able to lower his A1c from an 8.9 down to a 6.1.

Good product

I think this is a good product. I find myself needing to take high dose probiotics on occasion. It’s a bit on the pricier side and wish it was a little less expensive. I also use another brand sometimes where you get a little more for your money. I like that these come in individually wrapped packages though. No measuring or making a mess. I have to put this in something like applesauce or yogurt as it doesn’t have a great taste. Overall, I would purchase again when I have the finances to do so.

One of a kind

I’ve neglected taking my probiotics for years. I really needed each and every one of the 350 billion. Though I have not lost weight, these packets were a lifesaver when I had to go on antibiotics that tore up my gut. After one of these packs, I did not have to fear taking the rest of my prescription!

Glad to know this has helped you!

Gut bomb works

I took the high strength one for two weeks. My stomach and go system felt and worked much better although I did get some die-off (a minor herxheimer reaction) which I viewed as a positive - it meant the good gut bomb bacteria was killing off the bad ones. I mainly felt this reaction as joint ache which disappeared towards the end of treatment. I will definitely take again as I feel I could benefit from a few months of high strength probiotics

Olga H.
Less than I expected

Unfortunately, I didn't notice any big effects from this probiotic except maybe better digestion. No weight loss at all. The reason might be my Hashimoto's, probably I need to find something else.
