For muscle recovery and growth, this delivers a strong single-serving dose of 30g of protein per scoop from grass-fed **Whey Protein Isolate**. Research consistently shows 20–40g of high-quality protein per meal maximizes muscle protein synthesis, so you're right in the effective window.

Whey isolate is the most refined form of whey — it's had most of the fat and lactose removed, which is why you're seeing only 0.5g fat and 3g carbs per serving. That makes it a practical choice if you're watching your calorie intake or have mild lactose sensitivity. The 58 servings per container gives you solid value per scoop.

The sodium content is relatively high at 330mg per serving, which is worth tracking if you're managing your daily sodium intake. Otherwise, this is a straightforward protein supplement that delivers what it promises without unnecessary extras.
