I take two servings a day during a cycle and one serving a day off cycle as a year round support.
As to your second question. I don't know of any UK organic places that carry Cycle support but yu should talk with Sam/Dsade/Nutraplanet CS(board names) as they ship to all kinds of places and can answer this question as to what it would cost. Some people are surprised at how low the shipping can be where other places charge a buttload.
Both places carry the Cycle support.
