The product comes in a 3.44-pound jar (55.04 ounces) and is listed at $54.00, which translates to roughly $0.98 per ounce.

The ingredient list also notes White Tea Leaf Extract, which contains caffeine.
Who this is for
This product is positioned for endurance athletes seeking a high-carbohydrate fueling option with electrolytes. The gluten-free and vegan labeling makes it a potential fit for people avoiding gluten or animal-derived products. However, consumers should be aware that the packaging and some reviews point to caffeine content in at least some flavors, despite the title suggesting caffeine-free use.
Gluten safety and labeling considerations
Gluten-free labeling is present in the product data, and a gluten assessment view rates the product as likely safe for those avoiding gluten. There are no evidenced certifications (GFCO/NSF) in the supplied data. A notable watch-out is the potential caffeine content due to White Tea Leaf Extract in the ingredient list, which may vary by flavor.

Calorie counts per serving are typically around 240–250, supporting endurance fueling.
