INTRODUCTION TO NEW LEAF’S L-THEANINE CAPSULES – Our L-Theanine Capsules are specially formulated to support a balanced lifestyle, offering a two-month supply with 120 vegan capsules per bottle. Each serving delivers a potent dose of 400mg L-Theanine, an amino acid primarily found in green & black tea leaves. L-Theanine has been carefully extracted to preserve its purity and potency, making these capsules a simple, effective way to incorporate this beneficial amino acid into your daily regimen.
ENHANCED WITH VITAMIN B6 – To further enhance the efficacy of L-Theanine, we have enriched these capsules with Vitamin B6, known for its role in supporting normal psychological function. This addition not only complements the natural effects of L-Theanine but also contributes to the overall wellness of the mind & body. By combining these two key ingredients, New Leaf provides a holistic approach to well-being, ensuring that each capsule offers more than just the calming properties of L-Theanine.
