Effective energy boost

One of my best friends recommend this to me a month or so ago, I was complaining about lack of sleep and general lack of energy I experience some mornings, so I grabbed a bottle with my last Well.ca order.
I have definitely noticed an energy boost when I take one in the mornings, its not a blast of energy, just a small boost of alertness and general feeling of wakefulness. They contain ginseng, dried caffeine root and vitamin B12. I experience no side effects whatsoever and have taken with and without food in my system. They are easy to swallow, the usual size of a regular capsule containing powder. I don't use them all the time, maybe once or twice per week, the price is great, I bought a bottle of 90 for $15.00.
