About Nature’s Sunshine AnxiousLess
Life is full of moments that can put us on edge – big presentations, traffic jams, unexpected visits, and countless daily challenges. AnxiousLess is designed to help you navigate these stressful situations with greater calm and confidence. This unique formula combines time-honored botanical wisdom with modern nutritional science to support your body’s natural stress-response system.
The Power of Zembrin® – Clinically Studied Stress Relief
At the heart of AnxiousLess is Zembrin®, a patented extract from Sceletium tortuosum, a succulent plant native to South Africa. For over 300 years, indigenous people have used this remarkable herb to promote resilience during high-stress situations. Today, Zembrin® is the only Sceletium extract that has undergone extensive clinical testing, with seven human studies supporting its ability to help ease anxiousness and support a positive mood.
L-Theanine for Relaxed Alertness
Complementing Zembrin® is L-Theanine, a unique amino acid naturally found in tea leaves. Research shows that L-Theanine increases alpha brain wave activity, which is associated with a state of relaxed alertness. Studies have demonstrated that L-theanine administration can help reduce stress-related symptoms including anxiety and improve sleep quality, making it an ideal partner to Zembrin® in this comprehensive formula.
Essential Nutrients for Stress Support
The formula is further enhanced with carefully selected nutrients that help replenish your body’s stress-coping reserves. Thiamin (vitamin B1) supports proper nervous system function, as deficiencies have been linked to decreased levels of GABA, a key neurotransmitter involved in mood regulation. Magnesium plays a crucial role in muscle relaxation and nervous system support, while zinc has been studied for its potential to help reduce anger and support emotional balance.
Fast-Acting, Non-Drowsy Formula
What sets AnxiousLess apart is its fast-acting, non-drowsy nature. Unlike some stress-relief options that can leave you feeling sluggish, this formula is designed to help you stay alert and focused while feeling more calm and centered. Whether you’re dealing with everyday stress or facing a particularly challenging situation, AnxiousLess targets feelings of anxiousness from multiple pathways to help you feel your best.
Sustainable and Socially Responsible
Nature’s Sunshine is committed to sustainability and social responsibility. The Zembrin® in AnxiousLess is cultivated in partnership with the San Council, which represents the San Bushman People in South Africa. Profits from every bottle are shared with local communities, ensuring that you can feel good about feeling good.
