Small, but mighty
Many people don't get enough bright light during their day, particularly in fall and winter. The short, dark days can trigger symptoms of 'winter blues', like lack of energy, wanting to sleep more and socialise less. Vitamin L delivers effective and powerful light therapy which can help relieve the symptoms of winter blues.
