L-Huperzine A is an extract of the Chinese club moss Huperzia serrata. In China it is called Qian Ceng Ta and has been used for centuries. Each capsule contains 100 mcg of L-Huperzine A. Other ingredients are microcrystalline cellulose and gelatin capsule.

WHAT DOES IT DO?

Huperzine A is an alkaloid isolated from the Chinese Club Moss Huperzia serrata. L-Huperzine A is the natural form of Huperzine A and is 3 times more potent than synthetic forms.

Huperzine A is a potent acetylcholine esterase inhibitor. Acetylcholine is a neurotransmitter involved in memory and learning. Acetylcholine esterase breaks it down. By inhibiting this process it increases the amount of acetylcholine in the brain which has been shown to increase memory and learning performance in humans.

CAUTIONS

Huperzine A is non-toxic even at doses 100 times the therapeutic dose. Some cases of dizziness have emerged and the potential for nausea or excessive salivation is possible. Long term use is thought to potentially raise acetylcholine levels to an unacceptably high level. It is probably better to use this intermittently.

DOSE

Take 2 to 3 capsules daily with meals.

NHC sells 120 capsule bottles of L-Huperzine A 100 mcg for $16.99. The suggested retail price is $22.49.
