Why Choose Pure L-Theanine Powder?

Prescribed For Life offers a single-ingredient L-Theanine powder with a purity assay exceeding 99%, ensuring you receive a high-quality supplement free from additives, preservatives, or fillers. This pure amino acid powder is vegan, gluten-free, and non-GMO, making it suitable for a wide range of dietary needs. Each batch undergoes third-party lab testing to confirm its purity and potency, so you can trust that you are getting a genuine product. The powder is supplied in a durable, resealable pouch that keeps it fresh and easy to store, even in the 25 kg bulk size.

What Is L-Theanine?

L-Theanine is a naturally occurring amino acid most commonly found in green tea leaves. Unlike many amino acids, it does not build proteins but instead supports brain function and relaxation. Prescribed For Life provides this single-ingredient powder with a purity assay greater than 99%, delivering a potent supplement free from any extras.

Key Benefits of L-Theanine

L-Theanine is known for its unique ability to promote a state of calm alertness. It may help support natural energy levels without the jitters often associated with caffeine. Many people incorporate it into their daily wellness routine to encourage focus and relaxation. Research suggests it can increase alpha brain wave activity, which is associated with a relaxed but attentive mental state. As an amino acid supplement, L-Theanine also supports overall cognitive health. It is frequently used to help manage occasional stress and to improve sleep quality when taken before bed. However, individual results vary, and this product is a food supplement, not a medicine.

How to Uses L-Theanine Powder

L-Theanine powder can be mixed with water, juice, or your favourite beverage. Because it is a fine powder, it dissolves easily. Typical dosages range from 100 mg to 400 mg per day, but you should follow the recommended serving size on the label or consult a health care professional for personalized advice. The included scoop (if provided) makes measuring convenient. Start with a lower dose to assess your tolerance.

Quality and Purity

Prescribed For Life is committed to quality. This L-Theanine powder is manufactured in the USA in accordance with Good Manufacturing Practices (GMP). The assay guarantees over 99% purity, meaning you get a potent product with minimal impurities. The bulk size (25 kg) is ideal for regular users or for formulators creating their own supplements. All products are third-party lab tested. Certificates of analyse are available upon request, ensuring transparency and trust.
