I’ve formulated Zenith Brain C-13 into an easy-to-take capsule

Just take 3 capsules each morning. It’s quickly absorbed by your body, and there’s no aftertaste. It’s that simple!

With each dose, Huperzine A and the other ingredients inside Brain C-13 go to work safeguarding the vital connections inside your brain. Over the next few weeks, you’ll feel your memory, good mood, and quick thinking all start to strengthen.

In each capsule of Brain C-13, you get a precise dose of the key ingredient:

Cognizin® Citicoline

This molecule combines with oxygen in your bloodstream to create Acetylcholine, which forms your Mental Powerlines.

Supplementing with Cognizin® Citicoline is shown to help healthy levels of energy reach key centers of your brain.

Here’s the exciting news…

  • Harvard doctors reported that "citicoline supplementation can help to mitigate cognitive declines associated with aging by increasing energy reserves and utilization."
