Sero is designed for people who train, work, and stay active regularly. Not just athletes, but anyone who wants to perform at their best throughout the day. Whether you have long workdays, train multiple times a week, or simply want to stay properly hydrated without added sugar, artificial sweeteners, or unnecessary fillers, Sero fits seamlessly into your daily routine.

Sero may not be the right fit if you’re looking for a sweet, flavour-forward sports drink or a stimulant-style energy boost.

It’s also not designed for occasional or one-off hydration needs. Sero works best when used consistently, as part of a daily routine rather than a quick fix.

Sero is designed for daily use.

While it works well before, during, or after training, it’s just as effective on rest days, busy workdays, or whenever hydration and focus matter. Many people use it in the morning, during long afternoons, or whenever they want steady hydration without highs and crashes.

Sero supports hydration, focus, and recovery.

By providing a balanced electrolyte formula without sugar or unnecessary fillers, it helps maintain fluid balance and avoid the energy spikes and crashes common with traditional sports drinks.

Each ingredient in Sero has a clear role, and they’re formulated to work together, not compete.

The goal wasn’t to add more ingredients. It was to create the right balance for effective hydration and daily use, without unnecessary additives or trends.

Some people notice improved hydration or focus fairly quickly, while others feel the benefits more gradually.

Sero isn’t designed for a sudden “hit.” It’s built to support the body consistently over time, especially when used regularly.

Is Sero sugar-free?
Yes, Sero is completely sugar-free.

It's formulated without added sugars to avoid crashes and support hydration without unnecessary calories.

Yes, Sero is 100% vegan, gluten-free, non-GMO and sugar-free.

Each serving contains 3g of creatine monohydrate to support strength and performance.

Most people don’t need additional creatine unless they’re aiming for a higher daily intake (5g). Sero makes hitting your baseline creatine intake simple.

Yes. Sero works well alongside protein shakes, pre-workout and other daily supplements. The one thing to be mindful of is not doubling up on electrolytes. If you are already taking a high-sodium pre-workout, factor that in.

Most people notice improved hydration and steadier energy within the first one to two weeks. Creatine builds up over time, so consistent daily use for three to four weeks is when you typically experience the strength and recovery benefits most clearly. Daily use is key.

We aim to dispatch all orders within 1–2 business days. Once dispatched, standard UK delivery typically arrives within 2–3 business days. You will receive a confirmation email with tracking details as soon as your order is on its way. If you have not received your order within 5 business days of dispatch, please get in touch and we will look into it straight away.

Due to the nature of food supplements, we are unable to accept returns on any opened pouches. This is standard practice for supplement products and is in place for health and safety reasons. If your pouch is unopened and in its original condition, you have 30 days from receiving your order to contact us at sales@usesero.com to request a return. If your order arrives damaged or incorrect, please contact us immediately and we will make it right.

We recommend consulting your GP or a qualified healthcare professional before taking Sero if you are pregnant or breastfeeding. While the formula contains everyday ingredients including electrolytes, vitamin C and zinc, individual needs during pregnancy and breastfeeding vary and a healthcare professional is best placed to advise you based on your personal circumstances.

Each pouch contains 30 servings, which is a full month's supply at one serving per day. That is the recommended daily amount and the dose the formula is designed around. Most people use it first thing in the morning mixed with 400–500ml of water, though it works just as well at any time of day.
