Nuun Energy Caffeine + B Vitamins

Long training blocks eat into more than glycogen. By hour two of a hot run, a stacked work day, or a double workout plan, sodium loss and mental fatigue show up together.

Nuun's Energy Caffeine + B Vitamins is built to handle both hydration and energy needs in a single effervescent tablet — delivering 300mg of sodium and 80mg of plant-based caffeine 

Electrolytes + Energy – This tab handles sodium replacement and a caffeine lift together, so one bottle covers both jobs on long runs or back-to-back training days.

A Lift Without the Sugar Spike – The 80mg of caffeine comes from green tea leaf extract, and with just 1 gram of sugar per tablet, you get the boost without the spike-and-fade heavier energy drinks or coffee bring later into your day.

B Vitamins Doing the Metabolic Work – Each tablet carries 150% DV of B6 and 210% DV of B12, nutrients your body uses to convert fuel into usable energy, so it isn't riding on caffeine alone.

Each tablet carries five electrolytes — sodium, potassium, chloride, magnesium and calcium — dosed for workout-level sweat loss rather than everyday sipping, with 300 milligrams of sodium doing most of the rehydration work. The caffeine lands in a range athletes typically reach for as a pre-workout or midday performance boost. Riding alongside it are B6, B12 and pantothenic acid, three vitamins your body relies on to break down carbohydrate and fat into usable energy, which is why Nuun paired them with the caffeine instead of leaving the boost to stand on its own.

How to Use Nuun Energy Caffeine + B Vitamins

Drop one tablet into 16 fl oz of water, let it fully dissolve, and drink it down over the following 20 to 30 minutes.

Take it 30 to 45 minutes ahead of a workout or race start so the caffeine has time to kick in alongside your pre-hydration.

Use a tablet in place of an afternoon coffee when you need both fluid and focus without adding sugar to your day.
