Unflavoured

Efectiv Nutrition Carb Powder 500g, 2:1 dextrose and fructose blend

Efectiv Nutrition Carb Powder is a two-ingredient sports nutrition product: dextrose and fructose in a 2:1 ratio. There is nothing else in the bag. No flavouring, no sweeteners, no colours, no fillers. It is built for people who want an unflavoured carb base they can drop into any drink, shake or intra-workout bottle.

Each 20g scoop provides 19g of carbohydrates (13.33g dextrose, 6.67g fructose) at 76 calories per serving with zero fat, zero protein and no added salt. The dual-source approach uses two separate intestinal transporters (SGLT1 for glucose, GLUT5 for fructose), which allows for higher total carbohydrate absorption per hour than a single-source product. The 500g tub provides 25 servings.

Mix one to two scoops with 300 to 500ml of water depending on how many carbs you are targeting. Most users take a scoop pre-training, sip a diluted serving intra-training, or stir a scoop into a post-workout protein shake. The unflavoured profile means it disappears into juice, squash, electrolyte drinks and protein shakes without changing the taste.

Carb Powder suits endurance athletes, high-volume lifters and anyone training long or hard enough to benefit from targeted carbohydrate fuelling around sessions. If your sessions run under 45 minutes, supplemental carbs around training are usually unnecessary. For a flavoured intra-workout with electrolytes and a different carb source, Efectiv Performance Fuel uses Cluster Dextrin and added minerals.

Key Benefits

2:1 Dual-Source Blend

Optimised dextrose-to-fructose ratio engages both intestinal transporters for up to 50% greater carbohydrate absorption than single-source formulas.

Rapid Glycogen Recovery

Fast-acting carbohydrates restore depleted muscle glycogen stores quickly after training, reducing recovery time between sessions.

Easy on the Stomach

The dual-source approach reduces GI discomfort compared to high-dose single-source carbs by distributing absorption across two transporter pathways.

Unflavoured & Versatile

Dissolves instantly with zero taste impact, making it perfect for mixing into protein shakes, pre-workouts, or plain water before, during, or after training.

Frequently Asked Questions

How do I use Efectiv Carb Powder around training?

Mix 1 to 2 scoops with 300 to 500ml of water depending on how many carbs you want. Typical use is one scoop 30 minutes before training to top up muscle glycogen, sipped intra-workout for sessions over 60 minutes, or stirred into a post-training protein shake. Because it is unflavoured, you can add it to juice, squash or any other drink without changing the taste.

Why use a 2:1 dextrose to fructose blend in Carb Powder?

The intestines have two separate carbohydrate transporters: SGLT1 handles glucose (from dextrose) and GLUT5 handles fructose. A single-source carb maxes out its transporter at roughly 60g per hour. Combining dextrose and fructose at 2:1 engages both transporters together, allowing higher total carbohydrate absorption per hour. That is mainly useful for endurance work or sessions over 60 minutes where carb throughput becomes the bottleneck.

Do I actually need Efectiv Carb Powder for my training?

Whether you actually need Efectiv Carb Powder depends on your training volume and goals. If your sessions run under 45 minutes or sit at moderate intensity, you almost certainly do not - the carbs in your normal diet will cover that. Efectiv Carb Powder earns its place during longer endurance work, high-volume lifting blocks, second sessions on the same day, or training carried out in a calorie deficit when you still want energy around the session. For typical 30-45 minute gym sessions in a normal-calorie week, it is overkill.
