6 Reasons You're Flat by 3pm, no matter how much water you drink.
You're doing the right things. But the flat afternoons and the 2am calf cramps usually trace back to the same boring gap: minerals going out all day, and nothing coming back in.

01
Water Without Electrolytes Mostly Passes Straight Through.
Your body doesn't absorb water on volume alone. It needs sodium and other electrolytes to pull that water into your cells and keep it there. Drink litre after litre without them and most of it runs through, taking more minerals with it on the way out. That's how you can be "good with water" and still have dry lips by lunchtime.
02
Your Coffee Arrives
Before Your Water Does.
Two flat whites down before you've had a proper glass of water? Every cup nudges more fluid out than you'd think, so most mornings you're starting the day already behind. Nothing wrong with the coffee. It just needs minerals coming in behind it.
03
The Class and the Sauna
Take More Than Water Out.
A decent session sweats out sodium and potassium along with the water, and fifteen minutes in the sauna pulls out as much again. A shower and a sip at the fountain don't put any of it back. If you sweat on purpose most weeks, you're depleting on purpose too.
04
You're Losing Fluid All Night.
Night sweats and hot flushes drain you while you sleep, sometimes for hours at a stretch. If that's your season of life, you're waking up already down on fluid and minerals, which is why the headache is there before the day even starts. The morning glass of water helps. The minerals in it help more.
05
The 2am Calf Cramp Is a
Shortage, Not a Mystery.
Your muscles fire on sodium and potassium, with magnesium helping them switch off again. Run those low through an ordinary sweaty day, and a calf is liable to lock up right when you've finally fallen asleep. Cramps love a depleted system.
06
The Usual Fixes Were
Never Built for This.
More plain water just runs through you. The neon sports drinks are sugar and colouring built for teenagers on a rugby field, and pharmacy sachets are dosed for gastro (they taste like it, too). None of them were designed for everyday depletion. So we built Hydrate for exactly that.

I have tried many supplements over the years. Some I’ve stopped using because I didn’t notice a difference. I Will always aim to keep astaxanthin as part of my stack. I have noticed such an amazing change in my skin. My skin has always been good, but this has taken it to another level. I love this product! I particularly love the Biosphere brand as they use olive oil in the capsules, rather than seed oils. Really happy to support this NZ company.
Great product, I have been using it to help my eyes feel more comfortable ( post menopause) , they are definitely less scratchy than they were! I can’t wait to try the magnesium yet, it looks really good.
We both have the best sleep usimg this product. I am about to put in another order.
Lovely flavour and works really well.
I rely on 'Sleep' to help my sleep. Its a vial part of my evening ritual. I notice when I dont take it
Great for dry eyes. Best I've tried
Take this every night for restless legs and sleep . Alternate between the 2 flavours
Very good product but I did have to adapt it. I found taking it just before bed it would give me a hit of energy. So I no take it with dinner or just after around 7 and it gives my body time to process the ashwaganda. I still do have trouble sleeping but I do feel the nights I do sleep it’s a deeper sleep. I am going through a lot of stress and biological changes but I do feel it has helped just not as much as I hoped. The flavour is delicious and the customer service was awesome. I’m going to try the plain magnesium next time as I think ashwagandha not well suited to me
Great product - slept soundly :)
I’m loving this quality magnesium product from BioSphere as it has transformed the quality of my sleep.
I was sceptical but desperate when I started using Gut Support. After the first month, there hadn’t been a huge change, but I decided I was going to give it 2 months. Only a week into the second tub I noticed a definite change, and after not quite 2 months my system is so much calmer and more regular - the best it has been in nearly 6 years.
Nerve pain gone , deep sleeps after taking this . ! I am about to reorder , thanks guys 😍
This has been a game changer for me . It has eased pain and cramping at night . It promotes a feeling if calm and relaxation . I will never stop using this . Please buy it . I promise you won’t be sorry . Carolyn
Just love this product. I am on my third tin. I have been able to halve my blood pressure medication.
Sleep so much better and no more cramps
I won't need to ask for my money back. It works! The quality of my sleep has improved 10 fold.
Helps me stay asleep all night long
Prompt delivery and high quality. Noticed my eyesight not troubling me as much within a week.
It was a tough winter but this Biosphere Immune got us through.
I began taking this product 2 weeks ago to help with my sleep due to RLS and aching muscles due to injuries. Its great. I fall asleep well and sleep longer. I love the lemon lime flavour too!
Great quality astaxanthin and an easy addition to my daily supplement routine. I take it for its antioxidant, skin and general healthy-ageing benefits. Simple, well-dosed and no fuss. Very happy with it.
Awesome product!
Love it
Really like the flavour and taste, it encourages me to use it daily !
My husband and I have both been taking Biosphere Nitric Oxide, and we’ve been really happy with how we feel since starting it. We both feel so much better overall and have noticed a real difference in our general well-being and energy. It’s now become part of our daily routine, and based on our personal experience, we’re very pleased with it. It’s not often that we find a product that we both feel has made a noticeable difference, but this one has. We’ll definitely continue taking it!
Another one bites the dust! I’m really benefiting from taking this product every evening. I’m sleeping through the night, and waking refreshed. I would recommend this to anyone as a fuss free, easily digestible form of magnesium for settling your nervous system and allowing good sleep patterns.
Really like the Biosphere Magnesium. It's so helpful before and after hard physical work when I tend to get plagued with cramp. Alongside other salts & good hydration it's been great .Also very pleasant to drink. My wife also likes to use it at night for restless legs & to help relax. 😊
I love this product. I noticed an improvement in my skin. Looks and feels so much smoother.
I have systemic health issues and this is great for sleep, nerves and digestion (in a slow moving system). Great combination of types of magnesium. Easy to mix and take.
Great product. I take it every morning 🙂
Having parkinsons disease, exercise is very much my medication but has consequences the magnesium helps with the cramps and sleep quality which makes tomorrow better.
Love this product, after my first month I have far more mobility, energy and stamina, will be purchasing more...
I haven't gotten my very first bottle yet, but I will be ordering more. Capsules are easy to swallow, and makes it easy that need to take with food . Easy to remember with breakfast
It’s one of those things that you don’t you don’t know what you’ve got ‘til it’s gone! I was sleeping well and didn’t notice my gym recovery was good until I ran out of magnesium! Without it, my sleep is terrible and I’m sore for days after working out. Ordering more now!
On my second month of astaxanthin, not much change except a little more energy generally. Will give it a full three months.
I am so happy with my Astaxanthin . Can’t believe that it has worked so quick at pain relief . I have tried lots of other products in many years and I think this is the best thing I have tried . I have no pain and it so good . I hope this keeps up I have arthritis and and a few joint replacements so always in pain . Thank you
Awesome flavour magnesium for a massive day in the mountains!!!
Both flavours are nice and the powder mixes well. No longer getting night time cramps, so very happy with this. Will definitely be continuing with this product.
Awesome product.
Why Hydrate, when everyone suddenly sells electrolytes.
Fair question. Hydration is having its moment, and half the supplement aisle has a new tub out. Here's what's different about this one, specifically.
| HYDRATE | SPORTS DRINKS | IMPORTED SALT POWDERS | |
|---|---|---|---|
| Sodium per serve | 500mg: enough to do the job |
A sprinkle, buried in sugar |
1000mg+, tastes like the ocean |
| Sugar | None. Monk fruit does the sweetening |
The main ingredient |
Usually none |
| Beyond the two salts | Taurine 500mg, coconut water, ionic trace minerals |
No |
Rarely |
| Built for | Everyday depletion, one scoop a day |
Teenagers on a sports field |
Fasting and keto protocols |
Full label, full doses
What's in every scoop.
Every dose printed in full. Nothing hidden in a "proprietary blend".
500 mg
Sodium
as sodium chloride
THE ABSORBERThe mineral that lets the water you drink absorb instead of pass through. 500mg is enough to do the job without turning your bottle into seawater.
200 mg
Potassium
as potassium chloride
THE CRAMP MINERALWorks opposite sodium to move fluid into your cells. It's the one your muscles miss most when a calf locks up at 2am.
500 mg
Taurine
free-form amino acid
THE CELL REGULATORThe ingredient energy drinks built their name on, without the caffeine and sugar they wrap it in. Taurine helps regulate fluid balance inside your cells and supports muscle function.
1000 mg
Coconut water powder
concentrated
Nature's original electrolyte drink, concentrated. Adds naturally occurring potassium and rounds out the flavour.
50 mg
Magnesium
as magnesium malate
A steady daily top-up for muscle and nerve function. Already take our full Magnesium? This adds to it, it doesn't replace it.
100 mg
Ionic trace minerals
ConcenTrace® complex
A complex of naturally occurring trace minerals in ionic form, the form your body recognises. The small stuff modern food barely supplies.
Quick answers.
How soon will I notice anything?
If nighttime cramps are your main issue, that's often what people notice first. For steadier afternoons, give it a couple of weeks of daily use before you judge it. This is topping up a shortfall, not a stimulant, so it works by filling the tank rather than spiking you.
When and how do I take it?
One scoop in your first bottle of water for the day. That's the whole habit. Warm day, sauna, or a sweaty class? Have it then too. There's no wrong time and nothing to schedule it around.
Is there any sugar or caffeine?
Neither. It's sweetened with monk fruit, and there's nothing stimulant in the tub, so an afternoon scoop won't touch your sleep.
I watch my blood pressure. Is the sodium an issue?
Sodium is the point of an electrolyte, so yes, Hydrate carries a real dose of it. That's what pulls water into your system instead of letting it run straight through. If you're managing your blood pressure or taking medication for it, run it past your doctor or pharmacist first. They know your full picture, and the exact amount is printed on the label.
Can I take it if I'm pregnant, breastfeeding or on medication?
Check with your doctor or pharmacist first. They know your history and what else you've got on board. It's a simple electrolyte formula with nothing exotic in it, but they're the right people to confirm it fits your situation.
What if it doesn't work for me?
You've got 60 days. Take it daily, and if you're not glad you did, email us for a full refund. No need to post the tub back.
Make the water you already drink count.
You don't need another rule to follow. One scoop in tomorrow's first bottle, and let the afternoons tell you the rest.
