Ready. Prepd. Go!
PREPD is a fantastic product, backed by science. I was lucky enough to have access to a pre-market version which I used in Kona to great success (after testing in training of course). I was able to consume large amounts of water during the whole race which kept me very well hydrated and gave me the additive benefit of being able to consume more energy gels than usual (4 per hour) without gastric upset (gels need lots of water to be absorbed well). Here’s a bit more on PREPD. See the website for more details http://www.prepdhydration.com.au
The proprietary resistant starch in PREPD is resistant to digestion and is a pre-biotic (food for the good bacteria in the gut).
The proprietary resistant starch in PREPD is resistant to digestion and is a pre-biotic (food for the good bacteria in the gut).
Unlike digestible starch, resistant starch travels to the large intestine where it is broken down by bacteria to short-chain-fatty-acids [SCFAs]- e.g. acetate, butyrate and propionate. These SCFAs need to be produced in the large intestine as they are otherwise broken down by stomach acid if consumed directly, hence the unique PREPD RS-based drinks.
The presence of SCFAs encourages blood to flow into the vessels of the large intestine keeping the tissue healthy and increasing fluid absorption. This allows up to 5-6L more fluid per day to be absorbed!
The PREPD Prime drink should be consumed 6-18 hours before exercise so the resistant starch can reach the large intestine and prime the body for enhanced absorption of all other fluids consumed before and during exertion.
The PREPD Recover drink is a hypotonic formulation (low glucose at around 6g/L), has an optimal blend of electrolytes and tops up the body’s level of resistant starch to enhance rehydration in recovery.
Around 50% of the resistant starch isn’t digested and reaches the gut as a prebiotic, where it enhances hydration. The other 50% is actually digested and absorbed providing a slow-release source of glucose. With testing in training, there is actually a reasonable case for a full IRONMAN to have PREPD Prime the evening beforehand and then PREPD Recover maybe an hour before the race start. The Recover would provide some sodium loading, a slow release fuelling source and also top up the starch to further boost hydration in the run leg (although the Prime will still be delivering benefits then depending on the race duration). You could then have another Recover afterwards to boost rehydration in recovery.
In addition to the benefits of using PREPD for exercise, there’s also likely to be additional benefits to overall health from resistant starch. Check out the cool video below…..
