Are probiotics safe for toddlers and kids?

Jettie Melty Stix probiotics are completely safe for toddlers and kids (ages 2+). Probiotics play an essential role in creating a diverse, balanced microbiome that supports improved immune function, neurological development, digestion, and nutrient absorption.

Do probiotics help with diarrhea and constipation in kids?

Sick of monitoring your little one’s diaper and bathroom habits like it’s your job? The strains in Jettie are clinically proven to support digestion and limit constipation and diarrhea.

Why are probiotics important for a growing child?

The journey to a healthy gut microbiome starts the day a baby is born. As soon as your child starts breathing, touching, crawling and eating, they’re bringing all sorts of good (and bad) microorganisms into their body. 70% of immune function resides in the gut, and because your child doesn’t yet have a diverse microbiome, their immune system will be at an increased risk to harmful bacteria. By implementing a probiotic routine, you can help them strengthen their immune system while improving overall digestion. Jettie Melty Stix will target immunity and gut health, but can also relieve occasional constipation, gas, bloating, colic and diarrhea.

What are the ingredients in Jettie Melty Stix and what do they do?

Jettie Melty Stix combine the following ingredients to support various aspects of your child’s health.

PreforPro® - a non-fiber prebiotic that prepares your child’s gut for probiotics to work. We prefer this over other fiber-based prebiotics like inulin because it helps minimize gas and bloating.Four clinically researched and validated probiotic strains that are proven to support your child’s immune system and respiratory health, improve digestion and bowel movements, as well as support their oral health.Bacillus subtilis DE111®Lactobacillus acidophilus NCFMLactobacillus rhamnosus GGBifidobacterium lactis HN019Vitamin D to support healthy brain and bone development, oral health, and additional immune system support.Xylitol & Erthyritol to support oral health.

Are the ingredients non-GMO, and gluten, dairy and allergen free?

Yes, yes and yes. Jettie does not contain any major allergens as listed by the US Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA). You can see a full list of our ingredients above.

Is it okay to give my child probiotics daily?

Definitely. Jettie probiotics are meant to be taken every morning – the more consistently, the better.

Does Jettie contain added sugar?

No. Sugar –like artificial flavorings, dyes and colors – should never be in your kid’s supplements. Jettie Immunity Melty Stix is a sugar-free powder that carries both prebiotics and probiotics with all-natural orange flavor your kids will love, and none of the sugars and artificial colors.

What are Erythritol and Xylitol?

Both erythritol and xylitol are natural, sugar-free sweeteners you can find in fruits and vegetables, as well as the human body. They provide the sweetness that your children enjoy, but don’t cause as much trouble as added sugar (bad bacteria, cavities, etc.). In fact, erythritol and xylitol are used in many toothpastes for their oral health benefit.

What does silica do?

Silica is naturally found in foods like green beans, bananas, and leafy greens. It is added into Jettie to reduce moisture and protect the probiotics’ potency, which in turn maintains the product’s consistency. The amount of silica in Jettie is about the same as a medium sized peeled banana.

Does Jettie use artificial dyes and colors?

No. Health supplements shouldn’t have any artificial dyes or colors. End of story

What supporting studies have been conducted on the ingredients of Jettie?

Jettie probiotics are like Jetson – innovated at the speed of science. This means our ingredients are backed by the most promising clinical trials.

Does Jettie have a taste?

Melty Stix are orange flavored (more creamsicle than Sunny D) and can be poured directly onto the tongue, or mixed with as little as one ounce of water.

How long does Jettie last?

Your monthly subscriptions will include a Jettie stick pack for each day of the month. If you have any extras, you should throw them away after 1 year.

What can I expect during the first few weeks of Jettie?

When your child starts Jettie, you’re introducing a whole host of beneficial microbes that should quickly begin to multiply in their digestive tract. These friendly flora work hard to crowd out the types of bacteria and yeast you don’t want in their body. That’s great news—however, while they are taking hold and colonizing the digestive system, your child might experience a little gas and changes in the frequency and texture of their bowel movements. This is totally normal as the body adjusts to these changes.

After a few days or weeks, your child’s stomach will adapt and you’ll see (hear? smell?) less gas and things will settle. You might see more frequent or less frequent bowel movements (depending on their schedule) as the body is adjusting to the new gut health. Better absorption of nutrients means their bowel movements become more efficient or better quality.

How can I boost my child's immune system?

Keeping your child from getting sick is a common question we get from parents of infants, toddlers, preteens, you name it. Turns out, when kids are sick, parents' lives are put on hold– we can help you avoid that.

Because 70% of the immune system is in the gut, targeting gut health is the most effective way to ensure your baby has strengthened immunity. So what can you do to take their gut health into your hands? Take a high quality probiotic like Jettie (clinically validated strains, no sugar added, non GMO), limit added sugars and processed foods, opt for fruits, vegetables and whole grains. And one last thing… allow them to get a little dirty! Yes, dirt has all sorts of bacteria that can diversify the gut and strengthen their immune system.

Great so far

I ordered the seasonal subscription. So far I've used the Mood and Immunity. The Mood formula was especially interesting. I experienced a greater sense of calm. In situations where I normally would have experienced a lot of difficulty with certain emotional reactions I found it much easier to be mindful and relax. I have ADHD and autism and struggle with emotional dysregulation and the Mood formula went a lot farther than expected in preventing emotional outbursts and allowing me to take the moments of calm needed to process my feelings. I was genuinely surprised it worked as well as it did. Immunity is having a less obvious effect, but I already don't get sick very often so it's tough to gauge it accurately. I'm excited to try the Skin formula. If that one does what I'm hoping it will do I'm going to be amazed.

Great product

My digestive life has gotten so much better since taking the Jetson Probiotics, first two months the seasonal probiotic, now on the Womens for two months. Was plagued by external yeast infection for several months last fall, that issue has completely cleared. I think all the products I've used have been very helpful. I would recommend to anyone.

Great So Far

Have been using for a little over a month and am feeling some improvement with my digestion. Hoping it continues to improve.


Love for the entire family

Love it

I take this along with the gut prep. I have taken a million probiotics. In my other review I mention I’ve been laxative dependent for 8 years due to gastric bypass. It’s been hell. Nothing is ever helped me to even slightly wean off of them. I have taken motegrity and a list of other prescribed meds on top of that and again nothing worked long term. I’ve been told by many that probiotics can help move things along but never experienced that. I saw an ad on Facebook and read many reviews that people said they had more bowel movements. I can’t really rely on those but took a chance with the 30% off. I was shocked when I was going to the bathroom daily and hadn’t taken any laxatives. It’s been almost 3 months now and I haven’t had to take any laxatives. And for someone with a stretched colon and depend on them for 8 years. That’s a miracle!

Love it

It really helps to absorb more of the probiotic I believe. I have been laxative dependent for 8 years due to gastric bypass. Nothing has worked. Even the medicines that I started from a gastroenterologist eventually stopped working. I haven’t had to use laxatives in months. Everything else is an added bonus.

Great product

Great product and great customer service.

Highly recommend

Ihave been looking for the "right" probiotics for years. I have finally found them!
My overall health has improved over the year that I've been taking Jetson.
I have less pain and fatigue; caused by fibro. I have less days of feeling bloated when I don't make the healthiest food choices.
Best of all, I never run out, because they are delivered. With my busy schedule, I can't always remember to get to the store.
I have recommended Jetson to family and friends, coworkers and neighbors. Many of them have also started their own subscriptions; with excellent results.

Approaching normal

After getting c-diff January 1, 2020, it’s taken me months to get back on track. Doctors ruled out a host of other issues and these probiotics were recommended to me. After five months of issues and finally adding Jetson Probiotics to my routine, I feel much better.

Less bloating!

I can tell I have more regularity…. and better consistency! Definitely less bloating and indigestion!

Very effective

Great probiotic, very effective.

Great Product & Great Service!!!!!!

Like they say it won't solve your problems if all you eat is junk, but the product works as advertised. The subscription works great always plenty of notice and the orders arrive on time. Highly recommend!!!!


This ish works. I know because I tossed last month’s bottle in my car and forgot to take it, and low and behold my skin which mysteriously cleared up after starting jetson, broke right on out around my chin with a big nasty zit. My mood, which has been more lovely, went back to unpredictable and SAD. My stomach makes strange sounds after eating (another issue jetson solved) again, and I am TIRED. Anyways. Gonna go get my bottle out of the back seat now.

I'm on my third month of the seasonal subscription, seems to be going good, I don't notice any drastic changes with my digestion or overall seasonal benefits, but I've had serious gut issues most of my life prior to being diagnosed with hashimoto's autoimmune so I' had already done a lot of work on my gut prior, now just looking to supplement with a high quality probiotic. I like how the strains rotate seasonally as I would not be going out of my way to do that if I were buying probiotics myself. After trying all of them, I might opt to more customize my approach based on what I feel my body responded best to.


I feel better and have more energy with Jetson.

Feeling Good

I am really enjoying these probiotics. I have tried other brands that really didn't seem to do anything for me. I had been having some digestive issues and Jetson paired with a healthy diet has really helped get those issues in check.

Good Stuff Only

Ever since I've been taking Jetson, my body feels so much better. No more bloating or tummy aches. This stuff is great. Love the seasonal prebiotic subscription. Truly a game changer.

#2 issues solved!

I’ve been taking the seasonal probiotics for 3 months. The first two I also took the gut one. I’ve since just been taking the seasonal but added in a greens supplement. I’ve been regular a few weeks after I started taking it… and I really think my mood has improved.

Best Concept

The first program I found that bothers to rotate probiotic strains. And that is a concept that I can 100% get behind.
I have medical conditions that render my gut less healthy than the average person, so I never noticed much of a difference when I am taking a probiotic, but taking Jetson seasonal blend with the Gut Prep was the first time I have ever been able to know that a probiotic is doing me good.

Big Fan

I am so glad I made the decision to purchase the fit probiotics from Jetson. I have noticed less bloating, more energy and I am currently down 5 lbs.

So good

I love this stuff! It helps keep me regular and moving well. I’ve also seen a lot of improvements in the amount of bloating and gas.

I feel great

These products are great. Didn't realize how bad I was feeling. I'm not boated anymore, and feel overall better all day long!

Great Product

This is my 3rd month with Jetson. So far so good. I didn’t notice much at first, but I’m definitely having less stomach issues now than before. I like the autoship option, because I’ve never before kept taking probiotics past the first initial bottle.

Best I’ve used

Love the changing with the seasons approach. I’ve not experienced any untoward side effects as I’ve had with other probiotics I’ve tried…I just feel good!

Good so far!

I have been taking Jetson probiotics now for about 3 months. So far so good. Program is simple, clean packaging, and I’ve notice less break outs. Would recommend to others.
