“It Really Works”

I’ve tried a lot of hydration and sleep supplements, but this combo actually feels like it’s working. The Day Formula gives me a clean energy boost without the jitters.

David L | Customer

Verified Buyer

“Im sold”

Didn’t expect much to be honest, but after two weeks, I’m sold. The Night one has been amazing post-training, I recover quicker and I’m definitely sleeping deeper. I'm very early on so exited to see the benefits longer term.

Chris K | Customer

Verified Buyer

“I've Ditched the pre-workout”

I take mine during morning training and it keeps me going without needing a pre-workout which i've always relied on. The electrolytes are on point, and I actually feel more mentally sharp. I 100% recommend.

Dylan P | Customer

Verified Buyer

“”

I would 100% recommend to anyone who wants to optimise their workouts and mental clarity, I've just started on the Day formula, looking to buy the night to compliment each other. Great products, that actually work and do the job.

Your Questions Answered

Our most frequently asked questions. Anything else ask us HERE

Does it work?

Absolutely. You’ll feel the hydration and nootropic effects from day one, while adaptogens and cognitive compounds build over time. Most people feel sharper, more focused, and more balanced within the first 5–10 days.

When should I take it?

Day: First thing in the morning or before mental/physical activity

Night: 30–60 minutes before winding down or heading to bed

Together, they’re designed to bookend your day — setting you up to perform and recover, daily.

Is it safe to take every day?

Yes — ONYU is made for daily, long-term use, using research-backed ingredients with no artificial stimulants or fillers. It’s vegan, gluten-free, non-GMO, and made in the UK to the highest quality standards.

Can I use both products together?

Definitely — they’re designed to stand strong on their own, but work even better in synergy. Day gets you moving, Night brings you down. Together, they create a full-circle system for performance, recovery, and progression.
