When we launched we only had a 12 oz box offering and used a 3 oz serving to compare nutritional content between ZENB and other products on the market. Today, we also have an 8 oz box, which allows us to use a 3.5 oz serving for comparisons, another popular serving size among many products on the market.
The numbers you see for protein and fiber are only different based on the serving size being compared not on the nutritional value offered. You should always review the nutrition facts panel on the packaging to make sure you have a clear understanding of serving sizes and nutritional content.
