R-Line Electrolyte drink in 1 litre liquid concentrate form and SIX great flavours, has been specifically designed for endurance athletes to aid performance and provide fast hydration. It’s packed with the perfect combination of carbs and electrolytes with high amounts of sodium at 226mg per 250ml serve, and a blend of three carbohydrates so you can go faster and harder, for longer. R-Line differs to most other formulas in that it comes in liquid format – the one litre concentrated bottle can make 40 x 250ml serves to give you 10 litres of electrolyte drink. With a wide range of tasty, natural flavours, you’ll be spoilt for choice. R-Line contains 6.9g of carbohydrates per 100ml, providing 28 calories. This is made up of a blend of sucrose (5g/100ml), glucose (0.6g/100ml) and maltodextrin.
Is R-Line suitable for diabetics?
Maybe. If used correctly R-Line can be used by diabetics but diabetics should always consult a doctor before starting a new exercise or fitness routine.
The assumption that people with diabetes cannot consume simple sugars is outdated. All carbohydrate consumed (starch and sugars) impact blood glucose levels and the challenge for a person with diabetes is to match their carbohydrate intake to their requirements.
In the context of a sports-nutrition product some carbohydrate may well be appropriate depending on the duration and intensity of the activity being undertaken.
What ingredients are in R-Line?
Only what we think is needed:
Sucrose, water, glucose, maltodextrin, citric acid, sodium citrate, natural flavour (various), sodium chloride (salt), preservative (202), colour (various)
What is the carbohydrate content of R-Line?
R-Line contains 6.5g of carbohydrates per 100ml. This is made up of sucrose, glucose and maltodextrin.
What is the electrolyte content of R-Line?
R-Line contains 3.9mmol of sodium/90mg per 100ml. This is much higher than most other products on the New Zealand market.
Which electrolytes are included in R-Line?
We have only included one electrolyte, sodium. We don’t believe the inclusion of potassium, magnesium and calcium is justified.
I suffer from cramps, can R-Line help?
Current knowledge on cramp suggests two key causes:
Skeletal muscle overload and fatigue.
Heavy sweating and a subsequent significant sodium deficit.
R-Line has a much higher sodium content than most other sports drinks on the New Zealand market. Many people believe that magnesium, calcium and potassium are the key ingredient in sports drinks for combating cramp, and the sports supplement industry continues to advertise this despite research suggesting otherwise.
There is a lot of conflicting information on the internet regarding cramp. If you suffer from cramp and are looking for further information, you can refer to this article.

Does R-Line contain gluten?
Is it OK to use R-Line to wash down a gel?
No. As a general rule it is not a good idea to wash down any type of gel with any type of sports drink. This practice will result in a slowing of gastric (stomach) emptying which can lead to gastrointestinal distress (a sore gut to the rest of us). Basically it will stop the fluid from leaving the stomach into the small intestine to be absorbed quickly. It can also add to dehydration rather than prevent it.
Do you use colour in R-Line?
We think colour is essential for R-Line. When we were in the flavour development stages we were using colour free prototypes which we tested down at the local rugby club. Too many big, tough rugby players ended up angry with us after they mistook the prototypes for water and sprayed it on their faces. Funny though.
Likewise, we regularly sponsor drink stations at endurance events. It is essential that our drinks are coloured so they can be easily differentiated from the water option.
Our concentrates are 10x concentrated so the colour you see on the shop shelf is diluted down to a very faint shade.
Is there a colour free option?
Of course. Our delicious guava flavour has always been colour free, and we now have a full range of colour-free options available online.
I’m trying to lose weight (body mass), should I be using a sports drink?
Maybe yes, maybe no. If you use a sports drink to help you train harder and for longer, then it can definitely help you lose weight, and do it with less perceived effort. If you’re not pushing yourself though, its probably not going to help so get stuck in!
Is it suitable to give sports drinks to children?
Firstly, there is no reason why a fit, healthy kid shouldn’t drink a sports drink if they are exercising, especially in the heat. However, sports drinks aren’t soft drinks and shouldn’t be used as one by adults or children.
Children are particularly susceptible to heat illness and dehydration compared with adults. If they are exercising, then a sports drink might reduce the risks of problems developing. They can also help with recovery when playing multi-game and multi-day tournaments which is where we think they are most suitable.
If a child is sick with vomiting and/or diarrhea this can cause serious dehydration quickly and we do not recommend R-Line. For this you should see a doctor or use a specialised product available at the pharmacy.
How much sports drink should I use?
This is a tough question, the advice given to a small gymnast will be quite different to that of a prop forward. Even in professional sporting environments where dehydration testing equipment is available it’s a difficult topic. Here are some basic rules that you can use:
Rehydrate: Don’t turn up to your sport or training dehydrated. Thirst and dark coloured urine is a sign you might be dehydrated and dehydration can impede performance. A sports drink can help you hydrate before your sport or exercise. Over-hydrating isn’t a good idea either, no one wants to run onto the field and need to pee, just ask Jerry Collins!
Refuel: In endurance situations, you should take in carbohydrate at regular intervals; 250ml every 20 minutes is a guideline. Take your size into consideration and be sensible. There is a limit to the amount of fluid your stomach can cope with so don’t drink too much or you could end up with a sore tummy. It’s important for you to learn how your body responds to different sports drinks before competition day and never test a new drink in a game situation. An endurance athlete can burn about 60g of glucose and 30g of fructose per hour (there is some debate around that however); if you’re taking in more than this it’s probably not helping.
Rebound:Glycogen recovery is at its fastest straight after you’ve finished exercising and your blood is still pumping heavily to your muscles. It’s important to get carbohydrates into your body quickly so you’re ready to hit it full speed next time. A sports drink can help you do this, usually a lot quicker than food can. If you’ve been exercising in the heat it can also be a good idea to weigh yourself before and after an event and determine the difference in weight, you might be surprised! If you have lost weight, then multiply this weight loss by 1.5 and drink this weight in R-Line Electrolyte Drink. R-Line is particularly good when it comes to post match rehydration due to its high sodium content.
How long will R-Line last?
As a concentrate, R-Line has a shelf like of 1 year. It doesn’t need to be kept in the refrigerator once its opened, but its fine if you want to keep it in there.
A lot of powdered sports drinks need to be used within a day or they will start to turn bad, especially in the summer. This is not good if you’re using a hydration pack. R-Line is different; once mixed up, it will comfortably last a week, so there is no need to waste it. And as long as you’re sensible, it’s a great choice out there for using in a hydration pack.
What is the best way to measure out R-Line?
Without a doubt, the best way is to use a dispenser pump. We sell them here. Each pump dispenses 10ml, so it’s easy to figure out how much to use just 10 quick pumps per litre.
Is it ok to mix R-Line up stronger or weaker than the recommended amount?
Stronger not if you are using it during exercise. If you mix up any sports drink too strong it can slow down the rate that your stomach empties into your intestine; this can cause pain and result in you not getting the water, carbs and electrolytes you need, when you need them.
Weaker you can dilute it down to about 60% of the recommended quantity and it will remain within a typical sports drink specification. However, you will get less carbohydrates per hour of exercise.
Some similar products on the market contain Branch Chain Amino Acids (BCAA)? What do these do and do they help?
Back in 1991 some researchers came up with a complicated theory (Newsholme and colleagues) that suggested adding branch chain amino acids to sports drinks might improve performance. To date no one has proven this theory, yet marketing gurus are still telling us that this is the case. If you believe JFK, Elvis and Tupac are still alive, you might benefit from BCAA’s in your sports drink.

Williams. ‘Report of the Scientific Committee on Food on Composition and Specification of Food Intended to Meet the Expenditure of Intense Muscular Effort, Especially for Sportsmen.’ European Commission Health & Consumer Protection Directorate-General Scientific Committee On Food (2001)
What about B-vitamins and carnitine? Are they beneficial in a sports drink?
If they are, no one’s been smart enough to prove it and convince their fellow researchers.
