Solgar® 5-HTP is a complex formulated to help those individuals coping with modern day stresses and strains which may be effecting sleep or mood balance. This unique formula is designed to help you switch off from a busy day and aid a restful sleep in just 1-2 capsules a day. 5-HTP is a chemical created from an essential amino acid, which is then converted into serotonin. With our modern lifestyles, it can be hard to switch off after a long day and many of us find it difficult to wind down and get good quality sleep. Erratic eating habits may also contribute to low levels of serotonin. Serotonin is converted to melatonin, which is used by the body to create our sleep-wake cycle. When levels are low we find it hard to relax and drift off to sleep. The 100 mg of 5-HTP per capsule may support serotonin levels, which combined with Vitamin B6 contributes to the reduction of tiredness and fatigue. Finally the inclusion of valerian, which has also been traditionally used to reduce symptoms of anxiety and promote quality of sleep. Solgar® 5-HTP L-5-Hydroxytryptophan Complex Vegetable Capsules are suitable for vegans and are soya, dairy and gluten free.
