Full analysis

Quick assessment

When it comes to nutritional density and practical use, Soy Protein isolate powder clearly outperforms Dextrose powder. It provides almost 90 grams of Protein per 100 grams, making it ideal for muscle building and recovery.

Key differences

At a glance, Dextrose powder is purely carbohydrates with 100 grams of sugar and virtually no Protein or Fat. In contrast, Soy Protein isolate offers an extremely high Protein content (88g), very low Carbs (3g), and minimal Fat, making it a powerhouse for nutritional purposes.

Benefits

  • Dextrose powder: Quick energy boost, fast absorption, useful post-workout or in carb-loading scenarios.
  • Soy Protein isolate powder: High-quality plant-based Protein, supports muscle growth, and aids in recovery with fewer Carbs and fats.

Limitations

  • Dextrose powder: No Protein, high sugar content, not suitable for low-carb or Protein-focused diets.
  • Soy Protein isolate: Higher sodium (1000mg per 100g), which may be a concern for those monitoring salt intake; less effective as an immediate energy source compared to pure Carbs.

Best choice for different goals

If your primary goal is to increase muscle mass, recover from workouts, or support a high-Protein diet, soy Protein isolate is the clear winner. Conversely, Dextrose is better suited for quick carbohydrate replenishment during intense training or for energy spikes.

When one option is NOT worth it

Using Dextrose powder for muscle-building or meal replacements isn't effective due to its lack of Protein and high sugar load. Similarly, soy Protein isn't suitable when immediate energy is needed, such as during endurance activities requiring rapid glucose absorption.

Final recommendation

If you're focused on supporting muscle growth, recovery, or maintaining a high-Protein, low-carb diet, choose Soy Protein isolate powder. Opt for Dextrose only when you need fast energy replenishment and are not concerned with Protein intake. Remember, the best choice hinges on your specific nutrition goals.

How to interpret this page

🔥 Calories: Calories show energy per 100 g and help you compare portion impact across foods. Use them with protein and carbs to see whether an option fits maintenance, deficit, or surplus goals. A low score does not mean a food is ‘bad’ — it reflects nutrient density for general health, not your specific plan.

💪 Protein: Protein per 100 g shows how concentrated a food is as a protein source. Higher values support muscle recovery, satiety, and meal balance when that is your priority. Compare foods on this page rather than judging a single macro in isolation.

🌾 Carbs: Carbs matter most in context: training days, ketogenic diets, and endurance goals change what ‘good’ looks like. Powders such as maltodextrin score lower on our general-health scale because they are energy-dense with little protein, fiber, or micronutrients — not because they are never useful.

🥑 Fat: Fat carries more than twice the calories per gram than protein or carbs, so small portion changes matter. Moderate fat levels can support hormones and absorption of fat-soluble vitamins. Use this column with calories when balancing satiety and energy density.

Tip: combine the table with your goal — weight loss, muscle gain, low carb, endurance, or general health. The score helps compare options on this page; it does not replace medical or sports-nutrition advice.

Nutrition facts (per 100g)

The data shown is filtered to match this page’s topic.

The NutriDecide score (1–10) ranks foods on this page by protein, nutrient density, fiber, and a general-health lens — not by taste or whether they fit a specific diet. Low scores (e.g. maltodextrin) usually mean fewer nutrients per calorie; high scores (e.g. soy protein isolate) mean stronger protein and micronutrient density. It is a comparison tool: a low score does not forbid a food when it matches your goal.
