What changesAnd roughly when

train through
the heat.

First bottle

you stop carrying two products

Aminos and the four salts in the same clear drink, about 20 calories. Sip it through the session instead of choosing between hydrating and recovering.

First hot week

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.

First month

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.

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.

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.

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.

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.

Creatine and Peach Ice Tea Aminos 💖

I always use the creatine and the peach ice tea flavour aminos in the beautiful bottle - I honestly use Bare Nutrition daily to feel my best and just like I have that extra spark for a physical lifestyle

Bare Amino

Great product, im 60 years old and it help me a lot to put on some muscle.

Tastes amazing!

I have tried a few brands and by far this brand tastes the best. Its so easy to have straight after a workout and really quenched your thirst. I train 5-6 times a week and I feel like fresh and ready for my next session after this drink! You really can't go wrong with their products!

Excellent product! Used it for over a year now everyday and its doing amazing things for my body and recovery!

Fantastic addition to my vitamin regime! More energy, weight loss and all round healthier!

Hi Sam I am 53yrs old and been running for the past 20 yrs…..I have never seen and felt anything like I do now that I have started using your product ,it’s the best ,thank you so much 🙏🏻

These where the amino acids that I was running low on. So great-full for this product.

Absolutely love it!!! Makes me feel stronger in the gym, i have a clear head, focus is amazing, energy is fantastic, would love another tub!!

After my thorough research into the benefits of EAAs over traditional BCAAs, I went on a hunt to find a good quality EAA mix in South Africa. This is how I came across Bare Ayr and I must say it is probably the highest quality blend of all 9 essential aminos acids out there.

When taken regularly, I can feel the difference in the gym, post workout recovery as well as my overall energy and focus. I have 2 bottles now and intend to keep using Bare Ayr daily! But now please release an Iso Whey for us!!

So So impressed... everything from the customer care, packaging and especially with taste and effectiveness in the product! I've noticed that I have been sleeping a bit better as well, Which is a huge plus for me. Will definitely be carrying on with this product during my health journey.

Im not sure what I was expecting but WOW! I sleep SO well on this product. It has completely cut my sugar cravings and i'm no way near as hungry as I usually am during the day. I have just started training in gym recently and it has helped me perform along with recovery. Great results in such little time!

My father is 90 years old and broke his leg in May. He is mostly in a wheelchair now and walked about 10 metres a day. After 2 weeks on Hydrating amino's he is able to walk up to 20 metres at a time, and cylces for 15 min a day. He has increased the resistance on the bicycle since starting. He hates drinking water, but has no problem when it includes the hydrating aminos. He hopes for physical independence again with the help of the hydrating aminos

For me the product is a bit too sweet so you would have to drink it alone you couldn’t mix it into a smoothie
Mixing it was bit difficult the powder took time it dilute
