Please see specific promotion Terms & Conditions for details BFPO Addresses We do ship to BFPO addresses (with Royal Mail) but for active combat zones there is a strict 2kg weight limit (as with all deliveries to BFPO addresses), so please take this into account when ordering. As a guide, with careful packaging we can just get away with a 1.6kg tub. All orders under this weight limit will be treated as standard UK orders. All orders over this weight will be priced incrementally according to their weight (£5 per 2kg increase).

Consume directly from the pack during training or competition. Limit to one serving per day. Combine with other BETA Fuel products to achieve an hourly carbohydrate intake of 90–120g.

Combine with other energy supplements from the BETA range to achieve hourly 80-120g carbohydrate intake.

ENGINEERED FOR ENDURANCE

Engineered for endurance without compromise, BETA Fuel + Nootropics blends advanced carbohydrate delivery with nootropic focus support to help you think clearly, move efficiently, and push harder—long after fatigue sets in.

Engineered for Endurance

Endurance sports lasting 2 hours or more demand 90–120g of carbohydrates per hour to sustain peak performance

Engineered for Endurance

The longer the race, the smarter the fueling. Taking in 90–120g of carbs per hour keeps your energy and focus strong from start to finish. BETA Fuel Energy Gel + Nootropics delivers 40g of optimized carbohydrates per serving, combining fast-absorbing maltodextrin for immediate muscular energy and slower-metabolizing fructose for sustained release. 

OPTIMIZED DUAL-SOURCE FORMULA

Allows higher carbohydrate oxidation and intake for improved energy efficiency

AN OPTIMISED DUAL-SOURCE FORMULA

For endurance athletes (events typically lasting more than 2 hours), consuming 90–120 g of carbohydrates per hour is crucial for maintaining peak performance.


Fueling with SiS BETA FUEL Gel + Nootropics at a rate of 120 g per hour (with a 1:0.8 ratio of maltodextrin to fructose) during 3 hours of cycling produced peak oxidation rates of 1.58 g per minute with a 72% oxidation efficiency, highlighting the Beta Fuel Range as the most complete fueling solution in endurance sports.

ENHANCED WITH NOOTROPICS

Added nootropics aid cognitive function to curb the effects of fatigue.

ENHANCED WITH NOOTROPICS

Nootropics are naturally occurring ingredients shown to significantly boost cognitive performance during endurance exercise. Mental sharpness is critical in the later stages of training or competition, when quick decisions and focus matter most.
BETA FUEL Gel+ Nootropics includes:

  • Caffeine: improves information processing, concentration, and reaction time during exercise. When combined with carbohydrates, caffeine enhances endurance capacity compared to carbohydrates alone.
  • L-theanine: when paired with caffeine, it heightens alertness and focus while helping reduce jitters.
  • Taurine: taking 1 g before exercise has been shown to improve 3 km running performance by 1.7%.
  • Citicoline: supports faster information processing speed.
