How Does Phosphatidylserine Derived from Soy Compare to Bovine?

Chart: Phosphatidylserine derived from Soy Compared to Bovine. Years of improvement following 12 weeks of 300 mg of phosphatidylserine in Flavay Plus per day. 13.9 Years: Remembering names after introduction. 11.6 Years: Learning and Remembering written information. 7.4 Years: Recognizing a previously seen person. 3.9 Years: Dialing a ten-digit phone number from Memory.

The efficacy of phosphatidylserine (PS) in Flavay Plus® (non-GMO soy-derived) is superior to bovine-derived phosphatidylserine. (126)

Early studies used phosphatidylserine derived from cow brains (bovine cortex) but because mad cow disease was discovered in England, studies changed to soy-derived phosphatidylserine in the mid-1990s. Both animal studies (140,141,226,227) and human clinical trials (126, 139, 168) proved that soy-derived phosphatidylserine in in Flavay Plus® as effective as and better than bovine-derived phosphatidylserine.

A reversal of brain aging of nearly 14 years was found after 12 weeks of supplementation with 300 mg per day of phosphatidylserine in Flavay Plus®. Improvements were found in learning and remembering written information, remembering names and recognizing people, and memory of numbers. (168)

Over 3,000 published research papers and more than 60 clinical trials have established that phosphatidylserine in Flavay Plus® can rejuvenate your brain cell membranes and thereby:

  • strengthen your memory, (168, 126, 213)
  • increase vigilance and attention, (191, 215, 217)
  • boost learning, (191, 217)
  • increase mental acuity, (191, 213, 217)
  • intensify your concentration, (213, 217)
  • relieve depression and improve mood, (128-133, 191)
  • inhibit exercise and stress induced increases in cortisol, (117, 120, 121, 216)
  • decrease stress—for both young and old. (191)

Is Phosphatidyl
Serine Supplementation Safe?

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.”
