In the US, manufacturers are permitted to label a product as zero carbs if it has less than 1g per serving. US manufacturers are also permitted to label a product as zero calories if it has less than 5 cal. per serving.

re - Splenda .. the real counts

for 1 packet, equivalent to 2 tsp sweetness:
4 calories
0g prot
0g fat
1g carb (actually it's 0.988 )


for the granular bulk product, per 1 tsp serving
2 calories
0g prot
0g fat
0.5g carb

or ... for the granular bulk product, per CUP
96 calories
0g prot
0g fat
24g carbs
