Expert Insight from Dr. James Whitfield, Norysa Founder
Every family I work with whose parent has been diagnosed with Alzheimer's is told the same thing: take Aricept and monitor the decline. It slows the damage — but only through one pathway. What most American neurologists don't know is that Huperzine A, which has been a licensed prescription drug in Chinese hospitals since 1994, works on that same pathway more effectively — and also directly protects neurons against the plaques Aricept never touches. The reason it hasn't worked in American studies isn't the compound. It's that the active ingredient degrades during shipping. Fresh extraction changes everything."

Frequently Asked Questions
Does Huperzine A actually help with Alzheimer's and dementia?
Does Huperzine A actually help with Alzheimer's and dementia?
Yes — Chinese clinical studies spanning thirty years and thousands of patients have shown consistent improvement in memory, recognition, and cognitive function in Alzheimer's patients. It has been a licensed prescription drug in Chinese hospitals since 1994. It is one of the only natural compounds with this depth of clinical evidence behind it for this specific condition.
How does it work?
How does it work?
Alzheimer's progressively destroys the brain's primary memory chemical — acetylcholine — by allowing an enzyme called AChE to break it down faster than the brain can replace it. Huperzine A blocks that enzyme more effectively than Aricept, reaches the brain more reliably, and unlike Aricept, directly protects neurons against the plaques physically destroying brain tissue as the disease progresses.
How long until I see results?
How long until I see results?
Most families report noticing a difference between weeks 3 and 6. This is not a drug that works overnight — the brain needs time to restore what has been depleted. We recommend committing to a full 60-day trial before evaluating results. Stopping too early is the most common reason people feel it hasn't worked.
Are there any side effects?
Are there any side effects?
Huperzine A is well-tolerated by most people. Some experience mild nausea when starting, which typically resolves within the first week. Taking it with food helps. It is non-toxic even at doses significantly above the recommended amount.
Is it safe to take alongside Aricept or other medications?
Is it safe to take alongside Aricept or other medications?
Huperzine A and Aricept work on the same enzyme, so combining them can increase cholinergic activity. We strongly recommend consulting your doctor or neurologist before adding Norysa alongside any existing Alzheimer's medication. Most neurologists familiar with Huperzine A are comfortable supervising this combination.
What if it doesn't work for me?
What if it doesn't work for me?
We offer a 60-day money-back guarantee, no questions asked. You don't even need to return the bottle. The freshness of our extraction process means Norysa performs differently from degraded powder-based supplements — but if you don't feel it's making a difference, we don't think you should pay for it.
