Science In Sport (SIS) Hydro Sugar-Free Electrolyte Hydration Tablets Lemon Flavour I Rehydration & Energy, Gluten-Free, 20 Effervescent Tablets

I buy this quite often because it's good for when on the go. It's very practical and being effervescent very easy to use and transport. Mixes well without having to use a spoon and this one tastes really good. I would say it's effective enough as I use electrolytes for many years and increase my energy and my water intake. Generally I feel good when taking it. For the price the vitamins and nutrients are not bad.

My personal trainer swears by these, and I can see why. I have one every morning to stay hydrated for the day ahead and another after sports to rehydrate. I used to drink sugary electrolyte drinks, but this is a much better option for overall health and well-being.The tablets dissolve in about 2-3 minutes, and the taste is great no matter how much water you mix them with. Definitely a solid choice for anyone looking to stay hydrated without the extra sugar!

All round very good for hydrating and getting in your electrolytes etc, bought it for those hot days where I don’t have time to go out and buy the pre made drinks. Helps a lot when you have a headache but don’t want to spend an hour chugging down water or taking a paracetamol. It dilutes within a couple minutes and there’s no grittiness or bits floating around when it’s done mixing which is a plus.Only downside is the flavour (hence the 1 less star) its not terrible but could be a bit better. Not a dealbreaker though. Still good all in all. Good value for money.

Great product, I use them for long tennis matches to replenish my electrolytes and prevent cramp. The best plavour in my opinion is the berry, and great value for money.

The variety pack with Pineapple Mango, Berry, and Lemon flavors is a great way to keep things interesting. They dissolve quickly in water and taste delicious, making it easy to stay hydrated throughout the day. The added electrolytes help replenish what I lose during workouts, and I've noticed a significant improvement in my energy levels and recovery time. Highly recommend for anyone looking to stay hydrated and refreshed!

Love the taste of these, makes drinking water so much nicer with all the added benefits, defo feel more alert and have more energy

A good quality electrolyte tablet. I fill my water-bottle half way up and add a tablet. A little slow to dissolve but thats fine. As a boxer, in between circuits, its a God send. A squirt here and there really makes a difference. It tastes good in lemon and lifts that annoying mental fog and fatigue after all that sweating. No muscle cramps. Then after training I polish off the rest on the walk home. Gives a good energy boost. I highly recommend it, and works better than other brands I have tried.

The Science In Sport Hydro Hydration Tablets have some nice qualities but didn’t quite meet all my expectations. The lemon flavor is refreshing, and it's great to find a hydration tablet that’s both gluten-free and zero sugar. They dissolve easily in water, and I felt hydrated after using them, especially post-workout. However, the flavor is a bit weak and leaves a slightly bitter aftertaste, which might not be for everyone. Also, I wish they offered more servings per tube given the price.Overall, they're decent for hydration but not my top choice.
