Supports Healthy Sleep and Mood!

Tryptophan is a natural building block of serotonin‚ the neurotransmitter that plays an important role in appetite‚ mood‚ normal sleep patterns‚ and nervous-system health.

Serotonin has become a goldmine for the makers of patent medicines‚ but there are two vastly different approaches to making your body think it has more serotonin: one is to mimic it‚ the other is to make it.

With LIDTKE® L-Tryptophan there really is no better‚ no more-natural way to make serotonin.

Product Highlights:
- Promotes relaxation and sleep.
- Improves Mood.
- Reduces cravings for sweets and carbs.
