Real experiences from parents supporting their kids through the years that matter most.
Happygrow Growth Gummies are a hit with our kids! They love the watermelon flavor and look forward to taking them every day. The gummies are a complete multivitamin which gives them a nutritional boost. The packaging is great with 60 gummies providing good value. We have been using these for a couple of months and are very pleased with both the quality and the taste. Highly recommended for parents looking for a fun way to supplement their children's diet.Tonya H.
We've tried several gummy vitamins that were just way too sweet but these are a winner. The kids really like the taste, and I even tried one myself, the watermelon flavor is nice and light, and the texture is great. Since my kids are still on the younger side, I've been giving them just one a day. Like any gummy vitamin, I always make sure they have them right before we brush our teeth in the morning so the gummy-ness doesn't sit on their teeth all day. Definitely recommend if you want a vitamin that isn't a struggle to get them to take!Elizabeth O.
We've been really happy with these Happygrow Growth Gummies. The watermelon flavor is great and my child actually looks forward to taking them, which is a huge win since picky eating is an issue for us. I love that they include important nutrients like vitamin D, K2, and calcium to support bone health and overall growth. The gummies are soft, easy to chew, and don't have that chalky or artificial taste some supplements have. While I know growth depends on many factors, I feel good knowing my child is getting extra nutritional support in a form they enjoy. We'll definitely continue using these and would recommend them to other parents.Carol V.
I bought these for my son. He has been diligently taking them daily 2 in the am with breakfast. I have read the ingredients list they are quality, thru taste great and the detail on the gummies is absolutely adorable. Very happy with the purchase. Will post update in a few weeks how they work.Terri M.
Been looking for some bone support vitamins like calcium for my son to actually enjoy taking, and this was a great option. He likes fruit snacks and gummies of all kinds so he's not too picky with the particular taste. I'm happy to know we found something that works for him to make his bones stronger since he has a slim build and is very active and athletic.Emma C.
I don't typically leave feedback but this product deserves one. I have tried several other growth supplements for my son, but others are hard to swallow or didn't taste good and my son wouldn't take them. My son loves eating these Happygrow gummies. He eats one before going to sleep every night without me even asking him too. He has been eating them for 6 months now and has grown 5 inches. From 5'5 to 5'10. I can't say it's only because of vitamins because i make sure he eats healthy and sleeps 8-10 hours every night but I'll keep buying these for him as long as we see results and because they have good vitamins and nutrients regardless.Barbara E.
We have been buying these for almost a year now, my son has grown almost 7 inches this year and finally isn't the little guy in the friend group. I'm going to be honest, sometimes I do wonder and think maybe he was meant to hit a growth spurt...but also, honestly the confidence these gummies give him is worth all the weight in gold!Gloria O.
I bought these vitamins for my 15 year old brother, for the first two months I gave him these gummies along with omega 3, he grew 0.7 inches. I like the composition of vitamins, includes all necessary vitamins for teens. I signed wall before and after six months of drinking vitamins, you can see the increaseRonnie G.
The quality is top notch as always, the stars are a nice size, perfect for a 6 year old, our child take them every day and he likes them, it's too early to talk about the effectiveness of these vitamins, the watermelon flavor is pleasant, easy to chewDorothy A.
Getting my child adequate amounts of vitamins and minerals is a top priority. My child has enjoyed taking these supplements and finds the watermelon flavor to be tasty! This has been much easier than administering other supplements in the past. One serving delivers a meaningful share of the Daily Value for vitamin D in addition to several other vitamins. GMO free, gluten free. Give them a try!Debra F.
Reviews reflect the individual experiences of the people who submitted them and are not representative of the results you should expect. HappyGrow is a dietary supplement and does not increase a child's height beyond their natural potential.
The science
Most parents are told to “just wait for the growth spurt” and trust that genetics will take care of the rest. But medical research shows healthy height growth depends on a much bigger system working together — thyroid function, growth signals, active growth plates, and the key nutrients growing bodies need.
Simplified. Each step depends on the one above it.
Iodine helps your child’s thyroid make the hormones needed for normal growth. If iodine is low, this part of the growth system may not work as well as it should.
They also help the body’s natural growth-hormone system work properly during the growing years.
Growth hormone helps stimulate IGF-1, a key signal that supports normal bone growth while the growth plates are still open.
You can’t change your child’s genetics, but while they’re still growing, you can support their body with the key nutrients it needs during the years that matter most.
This section explains general human physiology and is provided for educational purposes only. It is not medical advice, and these studies examine individual nutrients rather than the HappyGrow formula. Nutrients support normal growth and development where intake is inadequate; no supplement can increase a child's height beyond their natural potential. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.
What to expect
Here’s a more real mom's journey version: For most parents, it’s about doing everything you can while they’re still growing staying consistent, supporting their growth, and watching for signs of progress and confidence along the way.
This part is about the habit, not the biology. Two gummies a day — most families land on breakfast because it's easier to remember. One bottle covers the month.
The routine stops being a decision. Nutrient gaps close gradually — this is the stretch where consistency does the work, alongside food, sleep and being outside.
Growth in children is measured over years, not weeks. The useful marker isn't a mirror — it's the growth chart at their next check-up. Keep going while the window is open.
18 ingredients chosen for the years that shape how a child grows — not a general multivitamin with "growth" on the label.
Iodine supports the thyroid, while calcium helps build growing bones. D3 helps absorb calcium, K2 helps guide it into bone, and magnesium supports bone strength — all working together during the growing years.
When your son is a picky eater, it’s easy to wonder if he’s getting what he needs. HappyGrow includes vitamin C, zinc and vitamin D3 to support normal immune function—helping you cover key nutrients alongside his everyday diet.
B vitamins help support everyday energy, while iodine supports the thyroid hormones involved in normal growth and development — a key part of the growth system many parents overlook.
You’ve checked the ingredients. But will he actually take them? HappyGrow brings daily nutrition together in soft, watermelon-flavored star gummies—just two a day, with no big pills to swallow or powders to mix.

My daughter has absolutely loved these gummies so far. She gets super excited about the cute star shape and loves the smell and the flavor. She always tries to eat more like they're candy because she likes the taste so much! The container is large and a lot come inside, definitely a great value for your money. Over all a great quality product! I'm very satisfied and will be ordering again.

My 13 yr old son was always on 30% for height, he's autistic with extreme picky eating. We've always tried to get him enough protein but calcium was a concern. He started taking these 4 months ago and will also choke down one glass of milk most days ( in addition to eating cheese) we measured him last night and he's grown almost 3 inches in 4 months. Not sure if it's a growth spurt but not going to stop these for some time.
Been looking for some bone support vitamins like calcium for my son to actually enjoy taking, and this was a great option. He likes fruit snacks and gummies of all kinds so he's not too picky with the particular taste. I'm happy to know we found something that works for him to make his bones stronger since he has a slim build and is very active and athletic.
I am very happy with the vitamins and it's so great to give my 10 year old. She is so excited and love her yummy stars! I tried many different brands and this is her favorite among those present on the market. The content and ingredients are the exact what we were looking for. I hope this supplement will help my hyperactive kid to grow tall and strong.
I bought the gummies for my nephews who are starting grow faster. Normally most growth supplements taste gross to them but the boys aren't complaining about the watermelon flavored Happy grow gummies. It was hard to find a supplement that helps them grow AND that has other vitamins without the heavy fillers. I also love that these gummies aren't covered in sugar which is really not necessary for kids. I'm getting a few more soon so both of them can try them for 6 months. Highly recommended.
Today I wanted to take the time to review this vitamin.My son who is 15 now started taking last December when he was (14). He was always the shortest in his class and he was very frustrated to be short.I took him to the doctor and we did a bunch of exams and everything was normal. The doctor said he was either a late boomer or just was going to be on the shorter side.My son started faithfully taking this gummies. He will forget anything else but this.Facebook just showed me those memories of 1 year apart with the pic we take on the first day to school and we were amazed!When he first started taking it was probably about 5'1". He is now 5'8". He is going to continue to take it because he thinks he can grow more. We even have a subscription on this.Everyone in school was commenting on how much he has grown over the summer! Coincidence because he maybe went through a growth spurt? Maybe! We will never know but we won't stop taking it and take the chance to stop growing!

We'll definitely continue using these and would recommend them to other parents.
Bought these for my teen son who is just a little on the smaller side. He says they taste great and would take more than the recommended 2 daily, if I'd let him. They don't have a smell, and the texture is as expected for a Gummy. He has grown in the last year. Not sure if it's because of the gummies, or just his time to grow. Either way, gonna keep on taking them!
Taste great my son likes it. Great for growing age. My son takes 2 gummies daily. The size is just right.
The gummies arrived fresh and securely sealed. I like the carefully selected ingredients and the clear supplement facts on the label. The watermelon flavor is pleasant, and the gummies have a soft texture that is easy to chew. The bottle is sturdy, the quality appears excellent, and the overall presentation gives a premium impression
Kids Love the Taste My child enjoys the watermelon taste of Happygrow Growth Gummies. The gummies are easy to chew and convenient to take every day. The quality is excellent, and the ingredients appear carefully selected. The bottle size provides a good number of servings and offers good value. Overall, a pleasant and convenient supplement.
The watermelon taste is great, both my children like it. The quality seems good! The calming effect also seems to work well for my child, able to better manage stress. We have finished one bottle, going on to the second bottle each. We like the star gummies, packaging is clean look, and the overall experience good and recommended! In terms of effect on height, it's too early to tell, probably needs about 6 months
I bought the Height Growth Gummies for my 14-year-old son, and so far, he likes the gummies. This is the second bottle that we got, and I am seeing progress in his height because his clothes do not fit like before, so I recommend the gummies if you want to help your teen's growth. The flavor is tasty.
These growth gummies have been amazing! My kid loves the taste and actually reminds me to give them their gummies every day. It's nice to find something that feels like a treat for her but also gives me peace of mind knowing she's getting extra nutrients to support her growth and development.The texture is great, the flavor is really good, and there's been zero struggle getting my child to take them. It's become an easy part of our daily routine.I'm really happy with this product and will definitely keep buying it. Highly recommend for any parent looking for a simple way to support their child's nutrition!
The quality ingredients are good and the gummies seem delicious. My child eats them well. I wanted to increase his height, so I searched it on google and bought it. It tasted much better than other products, so I repurchased another bottle.
They are just as described and quite convenient. You get a pretty good supply for the money that you spend and as far as I know, they get the job done. The bottle was sealed when it arrived and all the gummies were intact. Can't ask for much more than that. 5/5
First of all, my 6-year-old daughter loves the taste of this vitamin and thought it was an actual candy-gummy star. I actually smelled it before letting her try one, and it smells like bubble gum! So I knew she would like it. I have already noticed a difference in my daughter when it comes to energy and not being as drowsy after school. I plan on keeping this as part of her daily routine, and will definitely purchase these gummies again.
Digestion starts in the mouth, so, I like my gummies chewy. (And these are definitely chewy!) The watermelon flavor is a little more subtle, at least at first. As I've taken more gummies, the flavor's become more distinguishable. It's grown on me and I really dig it.Another thing I like is the level of calcium I get, without the hassle of taking horse pills. (Calcium supplements always seem so huge.) The calcium in happygrow gummies is palatable and super easy to take.I'll have to check back in six months to measure the height difference. Until then however, it's a good product; I'm satisfied and would personally recommend.
I always prefer to get my vitamins in gummy form -- these are a great alternative to swallowing pills.
This product was delivered very quickly, and I appreciate getting a free bottle with my purchase. My son has only been using for a week, so I do not have results yet, but we both have peace of mind knowing that we are trying to boost his height / growth by using these gummies. It seems like others have experienced success with this product. I will come back with an update once we start seeing results.
I got this growth gummies for my daughter and she loves it. She just started taking them.
My kids loved the taste of this one. As we've only had for a week I cannot attest to the it actually helping with growth but the ingredients are known for helping with bone growth. Getting my kids to take supplements has been made easier with this one as they love the taste and look forward to taking it. The size is perfect like an actual gummy star and are easy to chew and swallow.
I bought this for my 8-year-old son. He's been consumed it for over 5 days and has no side effect at all (no diarrhea no awful after taste). Hopefully prolonging taking the gummy star can help boost his height a little bit more.
As a pescatarian, it is hard for me to find gummies that do not have gelatin. I'm very happy that this product meets my needs and has no weird aftertaste, no gmos, and simple ingredients. I recently had jaw surgery and have taken this to help heal my bone fractures. I have taken the product for a week and already notice faster healing. I am also more relaxed, which is an added bonus, as a working mom who's always stressed. I highly recommend so far!
These gummies really work - no side effects!
Definitely worth it. I just started taking these gummies and already notice a decrease in joint soreness after working out. They actually taste pretty good. I am in my early twenties and wouldn't mind seeing if I can add a little more height. I am very selective about what I take, and all the ingredients are high quality. I plan on ordering again.
My 9yo loves these. They taste good and easy to remember to take. We also bought the nighttime gummies and they are equally delicious. We haven't seen any results yet but we only started them a month ago. Regardless they have many vitamins that are great for his growing mind and body.
I am satisfied with the growth gummies. I've been taking them for a week, so I can't speak about results yet, but the ingredients in the gummies are healthy, so I believe that, regardless of height, they are a good way to take vitamin supplements. And they are so yummy!
I actually like these chews. They taste like natural hichews. I've been taking for about a week now and so far so good. I am going to take for the recommended 3-6 months and I am hopeful that we'll see good results. The best parts in that all the ingredients are 100% natural.
We bought this for our son who just turned 16. He wants to be taller and he is still growing. These gummies have given him the push he needed. We will be buying more.
My twins loved it. The watermelon flavor is perfect for little ones. The quality of the ingredients and the size of the gummies are perfect for their age. We'll be optimistically waiting for the power and potency of the gummies!!!
Excellent composition, easy to chew, children are delighted with the taste! We have not been using it for long so far, I can't say anything about the result, but the product corresponds to the description 100%
I'm a 19-year-old female, and I take two gummies a day. I also do height-increasing exercises daily, like door hanging. In just 11 days, I've already grown 1 cm, even though I don't eat that healthy. The bottle size is amazing—you get 60 gummies inside, and they taste delicious! I can't wait to have them every day. I totally recommend them, and I'll be making them a part of my daily routine. Plus, the price is great!☝️⭐️
