Among channel swimmers, the Danish sports drink Maxim is something of a magical elixir. The reasons for this are beyond the scope of this post, but for additional details I recommend a search of the Channel Swimmers chat archives – especially posts by CS&PF pilot Michael Oram.
Maxim is an excellent product. Indeed, it fueled three of my four ultra-marathon events this year (Tampa, MIMS, and Catalina). What’s interesting about Maxim is how simple it is. The ingredients: 97% maltodextrin, with a smattering of Vitamins C and B1. Maltodextrin is a complex carbohydrate of chained glucose polymers, and is the basis for other popular endurance fuels including Perpetuem, HEED, and EFS. Maxim, however, has no added protein (Perpetuem), no added amino acids (EFS), and no added electrolytes (all three).
As you know if you read my DIY recovery drink post, bulk maltodextrin is available very cheaply – much cheaper than Maxim. So why pay $28 + $8 S/H to ship Maxim from the UK? (There is no currently no American importer of Maxim products.) Is Maxim maltodextrin superior to bulk maltodextrin?…
