2 year old Sleeping through since taking magnesium
Now I’m not sure if this is just coincidence but since buying the magnesium supplement which I had heard great things about my 2 year old has slept through. It’s so hard to find supplements for kids that aren’t full of sugar or sweetener so the only option for me was mighty kids. I don’t have a fussy daughter so she takes the medicine fine but can imagine it may be a little strong/ thick for some kids, but you can water down into juice etc.

We're absolutely thrilled to hear that your little one is sleeping through the night since starting our magnesium supplement! It's wonderful to know that you appreciate our commitment to creating supplements for children without added sugars or sweeteners. We also really appreciate your helpful suggestion about watering it down for other children. Thank you so much for sharing your positive experience and for placing your trust in us!
Fantastic
We get the multi vitamin, vitamin C and magnesium. We started by just getting Magnesium to help with sleep and moods, it definitely makes a difference to our kids. I was getting other vitamins from various other places but no matter what I researched there was always some rubbish ingredient or something lacking. We don't have loads of money so the idea of buying the mighty Kids vitamin C and Multi vitamin for both kids as well as the Magnesium, plus the frequency we'd have to pay for them - I put it off. I looked at finance again and thought 'do you know what?' I can do this and I will try it and see what it is like.
Firstly the kids like the taste - I give them in a syringe and they look forward to them every day. since having Mighty Kids our kids are rarely ill, if they get a cold, it doesn't develop - it is short lived and they fight things well. We are contemplating getting the Omega presently. We do get a probiotic for them elsewhere as sadly probiotic isn't in Mighty Kids.
At first it felt like alot to pay but our kids health is everything and worth the money, I know exactly what I am getting - plus it is a UK company that hasn't sold it's soul to big companies like Nestle like some other have. The ingredients are great and the story behind its beginnings a Mum who simply wanted to help her kids and what she wanted wasn't there - so she did it herself.
The website is great and so easy to use and change subscriptions info or delivery dates. The staff are also really good in communication

Transformation
Hi,
My 2.5-year-old daughter has been taking your magnesium supplement for the past two weeks, and I just wanted to share how impressed we’ve been with the results.
After just four days, we noticed a considerable improvement. She started sleeping through the night, became noticeably less irritable and began having far fewer tantrums. She genuinely seems so much happier and more settled since starting the supplement.
We’re absolutely delighted with the difference it has made and would highly recommend it to other parents.
Thank you ❤️

Wouldn't be without
Highly rate magnesium for my now 5 year old. Has made a huge difference in his emotional regulation and has helped so much with his school and day care setting. Have recommended it to many. Find the subscription very easy to pause, change flavours etc.

Thank you for taking the time to share your honest feedback.
We appreciate that our products are a little more of an investment, so we wanted to explain what sets our formulation apart. We use an innovative technology called liposomal encapsulation, which wraps nutrients in a protective layer to help them remain intact during digestion and be absorbed by cells. Our supplements are also a sustained-release formulation, meaning the nutrients remain present in the bloodstream and body for longer than traditional supplements, with bioavailability up to 37x higher than a standard supplement.
We use only the active forms of our nutrients, so the body doesn't need to convert them into usable forms, including methylated vitamins. Our products contain no artificial flavours or colours, only natural preservatives, and are sugar-free, GMO-free, vegan, and allergen-free.
We really appreciate you giving Mighty Kids a try, and we hope we may see you again in the future.
The magnesium seems like a good product…
The magnesium seems like a good product and has helped a lot of people looking at the reviews. Unfortunately it didn’t help with my autistic 5 year old’s sleep. It also took us trying a lot of different ways for him to take it. The first time we tried straight from a syringe and he ended up being physically sick. We tried it in his usual squash and smoothies but he wouldn’t drink it. Eventually he drank it when we put it in apple juice but like I say, it didn’t work for us!

We are really sorry that it did not work out for you this time around. Since everyone is built differently, results can show quite quickly for some, while for others it can take weeks or even months of consistent use to see a change. I will share a blog with more info below:

The magnesium is the best supplement I've ever tried
The magnesium is honestly the best supplement I've ever tried for my son. It has helped with his speech and he is sleeping the whole night. I'm on my second bottle, absolutely love it.

Their kids magnesium is absolutely brilliant for my 5 year old that's constantly in need of regulation. Finally he is sleeping through the night and regulating himself better in the day.

great quality vitamins
great quality items - Magnesium and Vitamin C. My 12 year old finds the taste too sour and strong so we mix it w/ fruit juice in the same meds pot. In contrast, my 7 year old loves the taste and drinks it neat. this is a great investment to our kids’ health and well-being. very-well packaged and next day delivery.

Mum and 2 children using every evening for magnesium to help regulate and sleep reducing the constant tossing and turning.
Yes it is expensive when buying even on subscription 3 bottles a time but if we can afford to continue it’s worth it.

Supreme service
Supreme service. Orders delivered quickly, and are always very well packaged.
The products themselves are excellent. We use the Magnesium, Multi vitamins and Vitamin C. They taste great, and work very well. I notice a difference if we run out of any of the 3 bottles. The magnesium keeps my son calm and he sleeps well. The multivitamins mean we are getting the nutrients which otherwise escape a fussy eater. The vitamin C is magical, especially at the first signs of a cold or flu; they never take hold properly and symptoms are gone within a matter of 48hrs max.
Please keep this going and dont fiddle with the formula!! 😊

Great product!
This is my second time ordering, was very happy with the magnesium! It helped my son focus so much more, we were able to talk to him and get him to understand better. We had stopped it when we ran out, unsure if this was the cause of the change and he reverted back to not understanding as well. He is now back on it and back on track! Ordering was very easy and the delivery is super fast! Could not recommend it enough!

Disappointing customer service after a product problem
I had ordered supplements from Mighty Kids several times before, including two bottles of Mighty Magnesium.
When I recently opened one of the sealed bottles, the contents were heavily crystallised, extremely thick and stuck to the sides of the bottle. I contacted the company, sent photographs and explained that the product had been stored normally and had only just been opened.
The company confirmed that the Best Before date had passed and advised me not to give the product to my child. I understand their policy and the fact that the bottle was opened after the Best Before date. However, I was disappointed that they refused to replace even one bottle as a goodwill gesture, despite my previous orders and the amount I had spent with them.
I was also unhappy with the suggestion that the smudged batch information on the cap must have resulted from significant moisture, repeated wiping or handling. This was not the case.
I appreciate that the company provided the batch details and a 10% discount code, but overall I did not feel valued as a returning customer. Unfortunately, after this experience, I would not feel confident ordering again or recommending the company.

Thank you for taking the time to share your feedback. We are genuinely sorry that you came away from this experience feeling disappointed, particularly since you are a repeat customer.
We completely understand why you were disappointed that we could not offer a replacement. We do feel we should clarify that you contacted us around 10 months after the purchase date and the product was already past its best-before date. As we advised at the time, we would not recommend giving a product to a child once it is past its Best Before date.
We did offer a 10% discount code towards a new order as a goodwill gesture, although we appreciate that you were unhappy with this resolution. We understand that this wasn’t the outcome you were hoping for, but we do need to ensure that we offer fair and consistent resolutions to all of our customers, and in this instance the timeframe was unfortunately far outside what we could reasonably consider for a replacement.
We’re also sorry that our comments regarding the batch information came across as though we were questioning your account of how the bottle had been stored or handled. That certainly wasn’t our intention.
We genuinely value every customer. We’re sorry that on this occasion we weren’t able to reach a resolution that left you feeling valued, but we do hope you can understand why we had to apply our policies consistently.

Amazing! As an adult, I take both the Magnesium and Vitamins and feel so much better for it. Also, my daughter and granddaughter take the Multi Vitamins. Amazing products! Highly recommend

Good products
I introduced Mighty Kids to my daughter starting with Magnesium. It was a good product but a little thick and sweet. Then I picked up more products such as Vitamin C and Fish oil. The vit C is good as it did keep her colds away but yet to try the fish oil. Overall, we did have a pleasant experience with the products and its company. I have recommended to friends and is definitely worth trying it though a bit pricey!
