Phosphatidylserine in Flavay Plus® may turn back the aging process in your brain. (126)

Phosphatidylserine in Flavay® Plus can revitalize the declining brain.

Well-designed, randomized controlled clinical trials show phosphatidylserine in Flavay® Plus can partially restore memory and other higher brain functions that have been lost. Phosphatidylserine in Flavay® Plus can revitalize the declining brain.

Double-blind studies involving more than 1,000 people show that phosphatidylserine in Flavay Plus® can be an effective for Alzheimer’s and other forms of dementia.

The largest of these studies followed 494 elderly subjects in northeastern Italy over a course of 6 months. All suffered from moderate to severe mental decline, as measured by standard tests. Treatment consisted of either 300 mg daily of phosphatidylserine or placebo. The group that took phosphatidylserine did significantly better in both behavior and mental function than the placebo group. Symptoms of depression also improved. (114)

These results agree with numerous other smaller double-blind studies involving a total of more than 500 people with Alzheimer’s, and other types of age-related dementia, who significantly improved by taking phosphatidylserine in Flavay Plus®. (119, 123, 219, 220, 222, 223, 224, 225)

Is Phosphatidyl
Serine Supplementation Safe?

Phosphatidylserine in Flavay Plus® is extracted from soy which is confirmed non-GMO. The phosphatidylserine in Flavay Plus® was the subject of many human clinical trials regarding memory loss, mood, cognitive performance and learning ability.

The use of phosphatidylserine in Flavay Plus® is well validated through clinical research and proven safe in standard toxicology tests.

The large number of human studies conducted on phosphatidylserine in Flavay Plus® produced a flawless safety record. First, it has proven compatible with a wide array of medications including: antacids, anti-hypertensives, anti-inflammatories, anti-ulcer and mucolytic agents, diuretics, anti-thrombotics, hypoglycemics, anti-arrhythmics, insulin, calcium channel blockers, calcitonin, chemotherapy drugs and other prescription medications. Second, phosphatidylserine is well tolerated by elderly patients with chronic diseases such as cerebrovascular, artery and vein disorders, heart diseases, high blood pressure, diabetes, lung diseases, digestive system diseases and arthritis.

Interestingly, clinical researchers found phosphatidylserine lowered uric acid levels and liver SGPT in their elderly patients—which can signify improved liver health. (106,110,114-117,119) More →

Authentic vs. “Borrowed” Science

Not all phosphatidylserine products are equal. The marketplace is full of inferior variations of scientifically proven natural products. Those who are looking for a product that will produce the proven results and not just “claimed” or “implied” results want authentic products proven in scientific research.


Consumers want phosphatidylserine that is proven safe and effective. Both phosphatidylserine in Flavay Plus® and Flavay® are proven in clinical trials. Flavay® was also patented as a “free-radical scavenger.”
