A complete plant-based protein powder built around two novel protein sources — Tendra® Fava Bean Protein Isolate and YESTEIN™ Fermented Nutritional Yeast Protein — with a genuine chocolate flavor from Nidau cocoa and Nightfall black cocoa. Free from dairy, soy, and gluten. 21g of protein per serving at 110 calories.
What's inside and why it matters:
Here's the Science
The primary nutritional question with plant protein is completeness and digestibility. Fava bean protein scores well on both. A 2021 review in Nutrients found that fava bean protein provides all essential amino acids in proportions adequate for human needs, with a protein digestibility-corrected amino acid score (PDCAAS) comparable to other legume proteins — lower than whey but meaningful within a varied diet.
The fermentation of the nutritional yeast protein is a significant processing advantage. Fermentation breaks down the cell walls of yeast, improving both protein digestibility and the bioaccessibility of B vitamins naturally present in yeast. A 2020 study in the Journal of Food Science found that fermented nutritional yeast produced significantly higher amino acid release during simulated digestion compared to non-fermented yeast.
Plant proteins generally have lower leucine content than whey, which means a higher total protein dose is needed to trigger the same muscle protein synthesis response. Research suggests that 30-40g of plant protein per serving achieves similar muscle protein synthesis rates to 20-25g of whey. For people committed to plant-based eating, hitting adequate total daily protein intake — 0.7-1g per pound of bodyweight — is the most important variable, and this product makes that more achievable.
The MCT oil addition supports ketone production and provides fast-absorbing fuel, making this well-suited for pre-workout use or as a meal replacement when calorie intake is deliberately managed.
Suggested use: Mix two scoops with 6-8 oz of water or your preferred plant-based milk. Post-workout or as a meal-support shake.
