ALTAR Speed Dust is a dual-source carbohydrate and electrolyte drink mix built specifically for endurance athletes who need sustained, gut-friendly fuel across long efforts. The formula combines maltodextrin and fructose — two carbohydrate sources that use different intestinal transporters, allowing higher total carbohydrate absorption per hour than single-source products. The result is 70g of carbohydrate per serving with no fat, no protein, and no unnecessary additives. Made in Ireland, formulated by ultra-endurance athletes.

• Dual-source carbohydrate blend — maltodextrin and fructose use separate gut absorption pathways (SGLT1 and GLUT5), enabling higher carbohydrate uptake than glucose or maltodextrin alone — the approach underpinning modern high-carb endurance fuelling.
• 70g carbohydrate per serving — 75g serving delivers 70g of carbohydrate and 288kcal, hitting the upper range for hourly carbohydrate intake recommended for sessions over 90 minutes.
• Electrolyte-fortified — sodium included to support fluid absorption and replace sweat losses on long efforts in warm conditions.
• Clean label — no fillers, no protein, no fat. Every ingredient serves a function.
• Three flavours — Raspberry Rush (light and vibrant with a clean, refreshing finish), Lemon Soda (crisp citrus kick), and Plain Jane (smooth, neutral, unflavoured).
• Approximately 13 servings per 1kg bag — 75g serving mixed with 500ml water.
• Made in Ireland — ALTAR was founded by ultra-endurance athlete Conor O'Keeffe, who developed the formula from his own training demands before launching it as a product.
