We offer our Sea Buckthorn Complete Vitality in two sizes. A suggestion is the 180 caps size pack as it is generously discounted. Why? Because Sea Buckthorn is a long term supplement with effects showing over time (although many people report noticeable changes after just a few days). A 3 month plan is recommended so that you give your body the chance to exhibit any derived benefits, then a reduction to a maintenance dose. A 180 caps pack allows you to do this in the most economical way.
