Always follow the serving size printed on your bottle. Across the range that is either two or four gummies a day — Sleep and NAD+ are two, while Creatine and Pre-Workout are four, because those active doses are larger. Every bottle states its own serving size and how many servings it contains, so check the label rather than assuming they are all the same.

Taking more than the stated serving will not speed anything up or improve your results. With a formula like creatine the benefit comes from taking the correct dose consistently over several weeks, not from taking extra on any one day.

Yes. Every Riva formula is sweetened without added sugar, so you get the taste of a gummy without the sugar crash.

Every Riva formula is Halal certified, and none of them contain animal gelatin — we use a plant-based gummy instead. The whole range is also sugar-free, sweetened with steviol glycosides and sugar alcohols rather than sugar itself.

Sleep — about thirty minutes before bed, once the screens are down and you are genuinely winding down. Pre-Workout — twenty to thirty minutes before you train, which gives the caffeine time to come up before your first working set. Creatine — any time of day, on training days and rest days alike, because consistency over weeks matters far more than timing. NAD+ — with breakfast, where it is easiest to remember.

It depends on the formula, and it varies from person to person. Creatine in particular works by saturating your muscles over time — give it three to four weeks of consistent daily use before you judge it.†

Most people can, and plenty of customers stack Creatine with Pre-Workout during the day and Sleep at night. Read the labels side by side so you are not doubling up on the same ingredient — the caffeine in Pre-Workout in particular is best kept well away from bedtime. If you take prescription medication or manage a medical condition, check with your doctor before combining formulas.

If you are pregnant or nursing, under eighteen, taking prescription medication, or managing a medical condition, please talk to your doctor before starting this or any other supplement. Pre-Workout contains caffeine and is not suitable late in the day for most people, and Sleep contains ashwagandha, which is not recommended during pregnancy.

Somewhere cool and dry, with the lid closed. Avoid direct sunlight and hot cars — gummies soften in heat.
