the last twenty minutes come back
Heat sessions end differently when sodium, potassium, magnesium and calcium are going back in while you work — not two hours later, at the kitchen sink.
summer stops setting the ceiling
The point isn't one heroic session. It's that a hot February week stops costing you the following one, so the training keeps stacking.

How to use it
One scoop in 500–750ml of cold water. Sip it through the session rather than downing it — start before you feel thirsty, finish before the session ends. On the long, hot ones, a second scoop in the back half.
Independent evidence · not our study
the conclusions aren't our opinion.
they're the ISSN's.
Hydrating Aminos carries the same nine-amino profile as Bare Aminos — 5,050mg total, 2,000mg of it leucine — with electrolytes added. In 2023 the International Society of Sports Nutrition reviewed the literature on essential amino acid supplementation and published ten conclusions as its official position. Here they are, and where our amino profile sits against them. We didn't run the study and we didn't choose the numbers. The electrolyte figures are ours, and are labelled as such.

Free-form aminos need no breaking down — they raise blood amino levels fast, and that rise is the trigger.

Ageing muscle needs a greater proportion of leucine to respond. That is our leucine dose.
Replace what sweat takes
4 salts
Sodium chloride 400mg giving 157mg sodium, potassium chloride 250mg giving 130mg potassium, magnesium 60mg elemental (from 300mg buffered glycinate), and tricalcium citrate 600mg giving 126mg calcium per serving. Bare's numbers — the electrolytes are ours to state, not part of the ISSN's position.
The full position
all ten conclusions, in plain language
01
ISSN position
Repair is the point
Protein turnover replaces the muscle proteins training degrades. That turnover is the metabolic foundation everything else sits on.
02
ISSN position
Free-form works fast
Free-form EAAs raise blood amino levels quickly, and that rise is what switches muscle protein synthesis on.
03
ISSN position
Safe to add
The safe upper limit of EAA intake comfortably accommodates supplementation on top of the food you already eat.
04
ISSN position
1.5–3g starts it
At rest, muscle protein synthesis is stimulated from as little as 1.5–3g, and plateaus around 15–18g.
Bare, not the ISSN
Every Hydrating Aminos serving delivers 5,050mg of essential aminos, including 2g of leucine.
05
ISSN position
Only the essentials
The non-essential aminos are not required for the response. Nine is the list that matters.
06
ISSN position
Better than protein
Gram for gram, free-form EAAs stimulate muscle protein synthesis more than an equivalent amount of intact protein.
07
ISSN position
Take it daily
Repeated EAA doses through the day do not blunt the anabolic response to your actual meals.
08
ISSN position
Age needs leucine
Ageing muscle is less sensitive — "anabolic resistance" — and needs a greater proportion of leucine to respond.
09
ISSN position
Even without training
In anabolic-resistant populations, EAA supplementation can improve functional outcomes without exercise attached.
10
ISSN position
More when cutting
EAA requirements rise in a caloric deficit. Meeting them is what preserves anabolic sensitivity while you lose weight.

Journal of the International Society of Sports Nutrition, 20(1), 2023. doi:10.1080/15502783.2023.2263409. These findings describe essential amino acids as a category — they say nothing about electrolytes, and Hydrating Aminos has not itself been the subject of a clinical trial.
so why not a shake and a hydration tab?
You still should eat — food first, always. This is for the sessions where a shake is too heavy to face and a plain electrolyte tab only does half the job.

“Have now been taking this for just over a month, and I must say I am feeling the benefits. I take a bottle to gym and also use on my MTB rides and never get the fatigue I used to suffer with. Highly recommended”

the honest answers.
When would I use this instead of Bare Aminos?
When heat and sweat are the thing limiting the session, not the weight. Same nine-amino profile either way — Hydrating Aminos adds 157mg sodium (from 400mg sodium chloride), 130mg potassium (from 250mg potassium chloride), 60mg elemental magnesium (from 300mg buffered glycinate) and 126mg calcium (from 600mg tricalcium citrate), so it's the one for long rides, hot classes, summer runs and anything where you'd otherwise be reaching for a separate electrolyte tab. Plenty of people keep both and swap by session.
How much sodium is actually in it?
157mg of elemental sodium per serving, from 400mg of sodium chloride. Alongside it: 130mg potassium (from 250mg potassium chloride), 60mg elemental magnesium (from 300mg buffered glycinate) and 126mg calcium (from 600mg tricalcium citrate). Those figures are printed on the label and repeated in full further up this page — no blends, nothing hidden behind a proprietary name.
Can I sip it through a long session?
That's what it's built for. One scoop in 500–750ml, sipped from the start rather than downed at the end. On the long, hot ones a second scoop in the back half is normal. It mixes clear and it's under 20 calories, so it won't sit heavy or compete with whatever you're using for fuel.
Can I take it with Pure Creatine or Carb Fuel?
Yes — they do different jobs. Creatine is a daily 5g habit and the time of day barely matters. Carb Fuel is the carbohydrate for during a long session. Hydrating Aminos is the amino load plus the salts, sipped while you train. Plenty of people run all three on a big day.
Will it break my fast?
Honestly, yes — if you're fasting strictly. A serving is under 20 calories and the aminos are absorbed straight away, which is the whole point of them. If you're doing time-restricted eating, most people take it at the end of the window, with the first meal, or around training. If you're fasting on medical advice, check with your healthcare professional first.
When does it ship, and what does delivery cost?
Orders ship from Durban in 2–4 working days, anywhere in South Africa. Delivery is free over R1250 and tracked on everything else. All prices are in ZAR.
