Of course water is the obvious answer I am looking for something more than water. I am doing a week long kayak ocean fishing trip in Panama in August and am looking to stay on as good shape as I can considering I will not only be baking in the sun for hours on end but will be using a lot of energy between pedaling the kayaks and cranking in fish and lures. I figured this group has to be the most physically active group so I figured I would ask the question here
I don't make a dime from these. Just trying to help out a neighbor.
You are going to be on the sea exposed to intense sun for long periods of time. I would add Lycopene and a good quality buffered vitamin C with those packs to counter oxidative stress. Sports Tech http://www.elementsofhealth.com/products/sportcompar.html
