L Huperzine A is meant to improve the blood circulation in people’s brains, effectively supplementing the oxygen supply and increasing focus and memory capacity.

It is a herbal supplement from Source Naturals, a company operating in the supplement market since 1982, time in which they built a name as one of top producers of herbal products to improve people’s health and well-being. Their focus on innovation won them an impressive reputation, as well as a series of awards for their products.

With most people working more than the usual 8-hour norm and having responsibilities at work as well as in their own homes, lack of focus and mental fatigue are more and more common to come across. L Huperzine A claims to eliminate this, providing the brain with extra focusing capacity and giving it a memory boost. Due to this, the supplement might also come in handy for students needing some extra support for that nasty final that’s lined up.

L Huperzine A Ingredients

L Huperzine A contains: Huperzine A, microcrystalline cellulose, stearic acid.

Product Features

The active ingredient in L Huperzine A is a natural alkaloid compound with the same name, extracted from a moss called Huperzia serrata.

Huperzine A belongs to a class of inhibitors that are frequently used to treat conditions such as glaucoma, Alzheimer’s disease, Postural Tachycardia Syndrome and Lewy Body Dementia. In fact, there are currently studies targeting Huperzine A as a form of treatment for neurodegenerative diseases, with research so far indicating a boost in cognitive capacities for patients treated with large amount of the substance.

The active substance is also considered an NMDA receptor antagonist, which conflicts with the manufacturer’s claims of the supplement boosting one’s memory. NMDA receptors are related to the memory function, and an antagonist for this class of receptors normally inhibits the functions performed by the targeted receptors. However, this does not entirely invalidate the product claims, as there are several substances that have different effects when in a compound than they do by themselves.

The recommended dose for L Huperzine A is 1 tablet, once or twice each day. It is not advised for pregnant, nursing or nursing women to take this supplement. If you are taking any other supplements or prescription medicine, consult your physician before trying L Huperzine A.

The potential side effects for this product include nausea, vomiting, muscle twitches, breathing issues and diarrhea. If you experience any of these symptoms, or any other unexpected effects, discontinue usage of the product and consult your physician.

  • natural supplement.
  • affordable product ( the producer’s recommended price for a bottle containing 100 capsules is 23$ + shipping costs).
  • manufacturing company has a reputation as one of the leading companies in the natural supplement industry.


  • product claims for improving focus and boosting memory are not fully supported by medical research.
  • no customer testimonials available on the manufacturer’s website.
  • no possibility of a free trial.
  • there are many supplements on the market proven to accomplish what this product claims to do.


L Huperzine A claims to accomplish something that most people in today’s busy working and studying environment need desperately: stimulating an individual’s capacity of focusing on tasks and helping him or her remember what needs to be done and how it’s done. Unfortunately, despite the amount of research done for the ingredients of this supplement, there is still little proof as to support or contradict the claims made by Source Naturals about their product.

There is, a large amount of supplements on the market that have proven effects in memory stimulation and focus improvement; however, not all of these products are natural, as L Huperzine A is. Ultimately, it is up to the consumer to decide whether this is the right products for them or not, but in reaching this decision we advise them to conduct their own research.
