Main Highlights

HEALTHIER FORMULA. Phosphatidylserine Capsules often upset the stomach due to fillers like magnesium stearate and microcrystalline cellulose, which have negative effects on digestion. However, Phosphatidylserine Capsules by Raw Powders contain a significantly reduced amount of magnesium stearate, with easy-to-digest, zero-gluten rice flour replacing microcrystalline cellulose. Raw Powders Phosphatidylserine Capsules are GMO-free and suitable for vegans and vegetarians.
MENTAL HEALTH SUPPORT. A Phospholipid Phosphatidylserine is the fundamental component of human cell membranes. Phosphatidylserine Vegan Capsules aid in Nerve System Support, Memory Maintenance by protecting cells and carrying messages between them. Taking additional Phosphatidylserine Supplements slows down the rise of cortisol levels, thus improving the Quality of Sleep, Reducing Mood Swings and Stress Symptoms.
THE DOSAGE. Several studies have shown that taking Phosphatidylserine has improved short-term memory, concentration and overall mood. The effect of Phosphatidylserine Vegan Capsules occurs when taking 1 capsule of Phosphatidylserine 100mg 1-3 times daily. Note: overdose might evoke unwanted side effects.
HIGHEST-QUALITY STANDARDS. Raw Powders Phosphatidylserine Capsules are manufactured according to Highest-Quality and User Suitability requirements. Precisely Laboratory tested Phosphatidylserine Capsules carry a Certificate of Analyses that proves the Quality and Effectiveness. Raw Powders Capsules contain 20% 100 mg Phoshphatidyl Serine.

ENVIRONMENTALLY FRIENDLY. Our Brain Boost Supplements are uniquely packaged in our Flex Packaging – a flexible, reclosable bag that boasts 5–10 times less of an impact on the environment than packaging made of glass, metal, and HDPE plastic. Lightweight and easy to open and close, our flexible bags save space not only in your pantry, but also during shipping and transportation – which means lower fuel consumption as well.
