Nuun Electrolyte Replacement Tablets
Initial Report - May 28, 2007
Name: Colleen Porter
Height: 5' 8" (1.73 m)
Weight: 140 lb (64 kg)
Email: tarbubble at yahoo dot com
Location: coastal southern California
Biography: I've been backpacking for about 11 years. I used to pack
HEAVY, but then I had kids. So to bring them backpacking I reduced my
pack weight drastically, and I'm now a quasi-ultralighter (roughly 11
lbs/5 kg solo base pack weight). However, I still have to carry the
kids' gear and food. I sew some of my own gear (tarps, tents, down
jacket). I mostly backpack in the mountains & deserts of southern
California, with occasional jaunts to adjacent states.
Year Manufactured: 2007
MSRP: $19.50 US for three tubes (12 tabs per tube)
Flavors: Tri-Berry, Lemon+Lime, Kona Cola, Citrus Fruit
Listed Weight: n/a
Tested Weights: 2.5 oz/71 g for one full tube
Product Description: Electrolyte replacement tablets that are
intended to be reconstituted in 16 oz/0.5 L of water. The tablets are
1 in/2.5 cm across and 0.25 in/0.64 cm thick, but can be easily split
in half. They are packaged in allegedly waterproof tubes that have a
very unusual apparatus attached to the underside of the lid - kind of
like a plastic spring with a short cylinder in the middle. The
cylinder is filled with an unidentifiable paper-like substance. My
guess (strictly a guess) is that this contains some kind of drying or
moisture-absorbing agent. The ingredients that all flavors have in
common are: citric acid, sorbitol, sodium bicarbonate, sodium
carbonate, potassium bicarbonate, magnesium sulfate, sodium benzoate,
polyethelene glycol, acesulfame potassium, ascorbic acid, calcium
carbonate and riboflavin-5-phosphate. Each contains "natural
flavors," and the Berry, Citrus and Cola flavors include beet (I
assume for coloring). The Kona Cola also includes caffeine.
Anticipated Field Condtions: Summer is hard upon us here in southern
California. I expect heat, and lots of it, with temperatures of over
100 degrees regularly. Our summers tend to be dry, so no real
humidity is anticipated. I will be using Nuun at the Pacific coast,
in the local foothills, and in our local mountains as well.
Elevations could reach over 10,000 feet/3000 m. Sadly, I expect no
precipitation whatsoever for the length of this test.

The tablet idea is cool. No packet to tear open, no chance of
spilling powder or having it blow away in an unexpected gust of wind.
The tablets are even scored (like an oversized pill) so that they can
be broken in half to make a single 8 oz/237 ml serving, or to fit the
two halves through a narrow-necked bottle. The tubes that Nuun
tablets come in are simple plastic tubes with a strange spring-like
plastic apparatus underneath the lid. I supect this apparatus may
hold some sort of moisture-absorbing agent, in order to keep the
tablets dry until they are used. The lid is initially sealed with a
breakaway plastic ring that comes off easily.
I have tried each flavor once so far. All of the flavors are mild,
subtle tastes - no assertiveness here. Although I am a bit of a sugar
junkie, I also like sour, tangy flavors. So my favorites so far are
Tri-Berry and Lemon+Lime. Citrus Fruit is also good, but I'm not at
all sure about Kona Cola. It's possible that I'm far too conditioned
to carbonated and heavily sweetened cola drinks. I thought that Kona
Cola tasted kind of like a cola soda that had been left alone too long
with ice melting into it. There is a mildly sweet taste to the
drinks, which I suspect is provided by sorbitol, a naturally-occurring
sugar alcohol. Nuun says sorbitol is a necessary ingredient "to help
it work as a tablet but it's at really low levels." Sorbitol is the
second ingredient listed.
The tablets dissolve in roughly two minutes and ten seconds. When I
drank immediately after a tablet finished dissolving, there was still
a slight amount of "fizz" to the water, but that dissipates fairly
quickly. If the tablets are dissolved inside a tightly sealed bottle,
some pressure does build but here at almost sea level this is just
enough to create a quick hiss of air when the bottle is opened. The
tablets impart a slight tint to water as well, with the Kona Cola
being the most noticeable.
On to performance so far. In the past few days, I have only been able
to use Nuun at the gym, not out on the trails. However, it seems very
promising based on my limited testing so far. I enjoyed drinking it
and did not miss the taste of my sweeter energy drinks at all. I do
believe that I felt less thirsty than I typically do, but I did
experience some lags in energy. However, I was not consciously
controlling my diet in order to obtain consistent results - on one
occasion, I had skimped a bit on breakfast, which could easily have
accounted for the energy lapses. This test will require me to pay
more rigorous attention to my caloric and liquid intakes, which I will
attempt to do.
Look for my Long Term Report here in roughly two months (early August
2007). Thanks to Nuun and BackpackGearTest.org for the opportunity to
test the Nuun electrolyte tablets.

Nice report. Nits below...

Comment: That's it, except that if they list the calories in a tablet,
that would be interesting to me... It answers the question about how
much sorbitol is not much.

excellent point and it hadn't even occurred to me. there are less
than 6 calories per tablet (<3 oz for each serving, 2 servings in one
tablet). i'll revise the IR to include this information. thank you

- Yes you are correct they use nuun in lower case.
Although if you look at their site and documentation, they dont
believe in capitialization at all.
Looks like i'll have to update my report as well.
