Diamond-Herpanacine of PA, Inc.
FDA issued a warning letter to Diamond-Herpanacine of PA, Inc. (President Leslie A. Diamond) on January 22, 2026, after reviewing the company's website and Facebook page in September 2025. The agency determined that marketing claims for two dietary supplements — Diamond Eye Health and Herpanacine Skin Support — characterized the products as intended to cure, mitigate, treat, or prevent diseases (including macular degeneration, herpes, eczema, and bacterial/viral skin conditions), rendering them unapproved new drugs and misbranded drugs under the Federal Food, Drug, and Cosmetic Act. FDA demanded a written response within 15 working days and warned that failure to comply could result in seizure or injunction.

LYSINE1 Attacks the herpes virus…
In 2007, I had cataracts surgery. Although the operation removed my cataracts, for years afterward, I suffered from almost constant eye pain and soreness. After reading and watching television too long I would sometimes even have blurred vision. Then I started taking Diamond Eye Health and everything changed. Within three weeks of starting this supplement, I noticed that my eyes did not get tired or sore or painful even after hours of reading, internet surfing, or watching television. I never get blurry vision anymore, and I feel that my vision has actually improved since I started taking this product.
In conclusion of the long-awaited studies, the National Eye Institute, a department of the NIH, announced that several of our powerful ingredients – are effective … in the fight against ocular degenerative disease.
