@texaszach37 @TheFEEDme Hello, they are available via our US website scienceinsport.com/us/

@ScienceinSport did yall discontinue the Hydro tablets? I can’t find any on @TheFEEDme

@jpathariya Yes, that would work perfectly fine 😃

@ScienceinSport Thanks, so for the longer run I should take SIS Isotonic gels (2-3 per hour) + 1 SIS Beta Nootropics for the final phase of my run.

Hello @ScienceinSport How many Beta Fuel + Nootropics Gels I can consume during a 3 hour run?

@StringerSport @RunThroughUK 🙌 🙌

Loved hosting @RunThroughUK Middlesbrough Half Marathon & Junior Race (in association with @ScienceinSport ) 🎤 Nearly 3000 runners with smiles at the end, medals & fond memories of the wonderful people of the north east 🙏 #RunThroughUK

@karikaalarayan @AmazonUK Hi Kaalan, we're sorry to hear you had a problem with our products. We'd appreciate it if you could reach out to our Customer Experience team so we can look into this with you - help.scienceinsport.com/en-GB/contact

🚨 Do not buy health supplements from @AmazonUK especially @ScienceinSport items. Though the product doesn’t suit your needs and if it rather affects your wellbeing, they want you to still consume it and not return it. Never had such bad experiences from any purchase before.

@4lex5tead Hi there, the best before date is located on the side of the gel packet as shown in the pictures attached. The date states Oct 24. Hope that helps!

@ScienceinSport so have a box load of these without any use by date all having to be binned as cannot confirm if they are safe to consume. Very let down as they are not a cheap purchase

We’re delighted to announce SiS as the Official Energy Gel Partner of all @RunThroughUK races in 2025 🎉 🔋 Our aim is to close the knowledge gap for runners of all abilities who want to fuel effectively for their training and races 🥇 #RunThroughUK #FuelledByScience

@mk123syd Hey! We've sent a DM with further details :)

how do I get an email response form @ScienceinSport or even a phone number

@kenda11fella Love to hear this Steve, great to have your support! 🙌 🔥

I've been using @ScienceinSport since I started running marathons. I've always got on well with their products, gels, recovery shakes etc. What has set them apart in my mind is their service. They went above and beyond this week - that is what keeps me coming back. Thank You!

@Take_156 They will be yes 😊

@ScienceinSport Thank you! And can you confirm they will be the 2 fl oz/60ml size?

@nycmarathon hi! Can you confirm the brand/size/flavor of gels on the course this year? Thanks!

@Take_156 Hi! Yes we can confirm that we will be at the NYC Marathon this year 😁 There will be a mix of flavours for the Isotonic Gels on course.

@ScienceinSport Is it you? Can you clarify?

@lborobasketball @LboroSport 🙌 🙌 🙌

Shoutout @ScienceinSport for supplying our new water bottles for this upcoming season! 🤝 @LboroSport | #WhereHistoryBegins

@CastlesConquest @HIGH5Nutrition Hey Paul! Can you send us a DM, we'd love to hear more about this 😊

@HIGH5Nutrition @ScienceinSport I'm planning a 90 mile bike ride for the charity MANUP? A men's mental health charity, the aim is to raise money and awareness but also to provide men with an opportunity to conquer their fears about talking about their mental health

@SteveRocknRolla Hey Steven! You can mix and match from both ranges. We'd just recommend to stick to the suggested use for each product as this can vary! All suggested use can be found on our website, on the product pages 😊

@ScienceinSport New to SIS products, looking for guidance on whether you can mix Isotonic products with Beta fuel products over a long event such as an ultra or do you still recommend sticking to single product range?

@sandjg1 Hi Stuart, a member of our team will be in touch with you today.

@ScienceinSport Wondering if I can get a response via X as I have been waiting for 5 days for a manager to call me back since you have tried to increase my subscription against your own advertised T&C's.

@Gymshark We do nutrition. With a bit of help from science

we do gym.

@teachfirstlast Hi! Thanks for your feedback, we'll be sure to pass this along to the relevant team. We apologise for any inconvenience!

@ScienceinSport this is the worst design of a bottle surely? It’s an endurance to get the damn thing open with that stupid shaped cap - sack the designer & bring back the bottle with the accessible top.
