Advanced Nootropic Geroprotector Supplement — Alpha is designed to enhance brain and nerve function for better aging. Each bottle contains a month supply (120 capsules) of the most effective natural nootropic geroprotectors, including clinical doses of Acetyl L Carnitine (ALCAR), L Alpha Glycerylphosphorylcholine (Alpha GPC), R Alpha Lipoic Acid, Ginkgo Biloba (24% Flavone Glycoside and 6% Terpene Lactone), and SerinAid Phosphatidylserine.
Open Source Formula — Alpha combines safe and effective natural nootropic geroprotectors in vegan capsules. We value your trust and know that we have to earn it. So we share all the information that you need to make the best decision, including every detail of the formula (unlike shady vendors who hide behind a proprietary blend). To ensure that you know exactly what and how much you're putting in your body, we fully and clearly identify all nutrients and doses in the supplement facts.
Best Scientific Evidence — Alpha is biotechnology based on multiple human studies (the gold standard of health science). In consultation with our advisor board of physicians and scientists, we perform extensive analysis of decades of clinical research from scientists around the world. Our algorithms rank hundreds of nutrients by parameters that include evidence, safety, and efficacy. And we develop formulas around only the most effective nutrients and doses (no snake oil or placebo dust).
Rigorous Quality Control — Alpha passes through multiple rounds of testing. Suppliers subject each nutrient to identity, potency, microbial, heavy metals, and other testing. Manufacturing follows strict GMP regulation in audited and certified facilities, verifying the test results of suppliers, and subjecting combined nutrients to more testing. And unlike most vendors who hide their test results (if they test at all), we publish all of our test results and certifications for you.
100-Day Money Back Guarantee — Order now with confidence. We want you to be happy, and we're confident that you will be. So your first Alpha comes with a generous guarantee. If you're not completely satisfied within 100 days of delivery, you'll get 100% of your money back. No need to return the product. Just contact Thrivous with your order information.
