How do I know if I am purchasing the purified HupA demonstrated in the research?
The only way to verify the source of the huperzine A in a product is to ask the supplier if it is in the form of a standardized extract of Huperzia serrata or the purified molecule used in clinical trials. This may surprise you, but simply looking at the ingredient panel on a product label will not provide the distinction since all products that use the standardized extract is only required to list the amount of HupA provided by the extract. This is an unfortunate situation for consumers.
