Splenda/sucralose is a totally artificial molecule which doesn't exist in nature. It is thought to be toxic. Quoting from the Dr Mercola site (link below):
"Research in animals has shown that sucralose can cause many problems in rats, mice, and rabbits, such as:
Shrunken thymus glands (up to 40% shrinkage)
Enlarged liver and kidneys.
Atrophy of lymph follicles in the spleen and thymus
Increased cecal weight
Reduced growth rate
Decreased red blood cell count
Hyperplasia of the pelvis
Extension of the pregnancy period
Aborted pregnancy
Decreased fetal body weights and placental weights
Diarrhea"
I have found sucralose in cheap supplements - watch out for it - but I always return any that I find telling the store about the potential dangers of this new sweetener.
