I have used Prevagen regularly for more than 2 years and always felt it was helpful with preserving and improving memory and other cognitive functions. I always keep a supply on hand as I found it sells out quickly and is often hard to find. I now have 6 new, unopened, recently purchased 30 capsule bottles. A recent medical revelation has indicated that I will not be able to use these so I offer the lot to clear my medicine cabinet. I don't think this medication has an expiration date but even if so, these were all purchased in the last few months. Original cost was about $40 per bottle. They are yours (all 6) for $150.00
