I used to get severe calf cramps every time I ran past mile 10 in the heat. Since switching to beHydrate, my legs feel fresh, my stomach stays completely calm, and I finished my last half-marathon cramp-free!

How to use

How & When to Use

  • Daily / 30–45 Mins Before: Drink 1 pouch to build optimal blood volume and prime your body's cooling system.
  • During Exercise: Take small sips every 15 minutes to match your sweat rate and prevent cramps.

  • 🎒 Pocket-Safe Format: Sits flat in hydration vests, belts, or shorts with zero bouncing and quick single-hand access.

The Science Behind the Protocol

🩸 Lower Heart Strain Before You Start

A tiny 1–2% drop in fluid forces your heart to work significantly harder. Pre-loading electrolytes expands your blood plasma volume, lowering heart strain and keeping you cool from your very first stride.

⚡ Prevent Muscle Cramps & Brain Fog

Sweating drains the essential minerals your nervous system needs to fire muscles. Continuous mineral intake keeps nerve signals clear, stopping painful cramps, headaches, and sudden fatigue mid-run.

💧 Lock In Post-Run Hydration

Drinking plain water post-run dilutes your blood sodium, causing your body to flush it out as urine. beHydrate changes fluid osmolality so your body actually retains the water and pulls it deep into depleted cells.

Ingredients

  • 100mg vitamin C
  • 45mg Magnesium
  • 398mg Chloride
  • 133mg Potassium
  • 125mg Sodium
  • Spring water

The Science: Why Isotonic Hydration Bypasses Stomach Cramps

Isotonic vs. Hypertonic: Stop Fighting Your Stomach

Ever wonder why traditional sports drinks feel heavy and sickly mid-run? They are hypertonic, loaded with sugars that trap liquid in your digestive tract and pull precious water away from your muscles.

beHydrate is 100% Isotonic. Because its mineral concentration matches your blood plasma, it bypasses digestive breakdown entirely.

  • ⚡ 2x Faster Absorption than plain water or sugary drinks.
  • 🫄 Zero Stomach Sloshing, even at max-effort race pace.
  • 🧂 Pure Osmotic Pull: Forces essential electrolytes deep into depleted cell tissue.

Frequently Asked Questions

Got questions? We’ve got answers!

Does beHydrate actually work?

Not only does behHydrate contain the nutrients proven by science to maintain a strong performance, Ben uses during his training, marathon's and triathlons to prevent cramps, headaches and other issues such as brain fog during high intensity exercise.

Shouldn't I drink water?

Obviously water is the source of life, however, during exercise you need more than just water to be adequately hydrated for best performance.

How many pouches of beHydrate do I need?

this depends on your activity levels, temperature and duration. We would recommend to 'drink to thirst' during colder weather and typically drink at least 2 pouches per hour during during higher intensity exercise or hotter weather that makes you sweat more.

How do I know if I need beHydrate?

Check the colour of your urine. If it is any darker than a light yellow or straw colour, you need to hydrate.

When should I drink beHydrate?

Water doesn't cut it for any exercise that lasts an hour or more, or in warm weather. You will sweat minerals out of your body that you need to help regulkate muscle function, body temperature and hydration. Therefore, use beHydrate in these circumstances.

Why did you create beHydrate?

I hated using powders to mix with water or those effervescent tablets that didn't ever taste very nice and left a white residue in water containers. I also wanted to move away from bulky and heavier bottles. Furthermore, Ben suffered from severe muscle cramps during a hot, sweaty Vienna marathon and was determined it wouldn't happen again, so he initiated the creation of beHydrate.

Does beHydrate contain sugar?

No, beHydrate is sugar-free. We want beHydrate to be used every day without the worry about consuming too much sugar. We have our Sports Sweets if you need carbohydrates.

Why is beHydrate in a pouch?

After testing and deliberation, we wanted a container that could be squeezed into runners' vests, belts and loops that are found on running clothing. When it's empty, it can be rolled up and stored away until you find a bin.

Should I do a sweat test?

A sweat test is a simple way of knowing how much fluid you need per hour during typical exercise or training. Simply weight yourself naked before the activity, carry out the activity for 30 minutes without drinking or eating anything, and then weifght yourself naked again after 30 minutes. The weight lost in grams is the amount of fluid you need in millilitres every 30 minutes.

Does beHydrate contain caffeine?

No, beHydrate is purely a hydration formula that is ready-to-drink (RTD). We have a product called beEnergy that contains caffeine.
