The Orbana energy drink, which recently launched into the UK, was used by comedian Eddie Izzard during his Sport Relief marathon challenge, which saw him run an incredible 43 marathons in 51 days.

A mixture of vitamins, minerals, amino acids and electrolytes, the drink is purchased in powder form so that the key ingredients don't dilute over time while sitting in a liquid solution.

When water is added to the powder, the resulting drink is claimed to delay fatigue by up to two hours without the 'spike' or 'crash' sensation experienced with other energy drinks. Orbana is available in either a 4-pack, a 24 bottle case or an 800g tub.
