One of the biggest differences between electrolyte products is dosage.

Many formulations provide relatively small amounts of key minerals - often as little as 200-400mg of sodium, 100-200mg of potassium, and 10-30mg of magnesium per serving.

While these numbers may look reasonable at a glance, they can fall short of what’s needed to meaningfully support hydration, particularly for those who are active, sweating, or following a low-carb approach.

In practice, this means some electrolyte products contribute very little beyond flavour.

A more considered approach is to use meaningful, functional doses - for example, levels in the region of 500mg sodium, 500mg potassium, and a useful contribution of magnesium per serving - so that the product can actually support hydration and performance in a real-world setting.

The form of each mineral plays a major role in how well it’s absorbed and utilised.

Some commonly used forms are chosen for cost or convenience rather than effectiveness:

• Magnesium oxide - widely used but poorly absorbed
  
• Potassium chloride - efficient, but often harsh in taste and less well tolerated at higher doses
  
• Refined sodium chloride - effective for sodium delivery, but stripped of naturally occurring trace minerals
  

More bioavailable forms - such as citrate-based minerals - tend to be better absorbed and more suitable for drink-based formulations.

For example, using forms like potassium tricitrate and magnesium tricitrate, alongside a more natural sodium source such as minimally processed sea salt, allows for a formulation that is both effective and more balanced in how it performs.

Traditional sports drinks are often grouped into the same category as electrolyte supplements, but they’re designed with a different goal in mind.

Many contain significant amounts of sugar or sweeteners, with relatively modest electrolyte levels in comparison. Their primary function is to deliver quick carbohydrates, rather than optimise electrolyte balance.

For those specifically looking to support hydration without added sugars, this can make them a less suitable option.

There’s often a trade-off between taste and effectiveness.

Lower electrolyte levels are easier to flavour and more palatable, which is why some products prioritise drinkability over function. However, reducing key minerals - particularly sodium - can limit how effective a product is from a hydration perspective.

A well-formulated electrolyte needs to strike a balance between the two - delivering enough of the right minerals, while still being something you’ll actually want to drink consistently.

If your goal is proper hydration and performance support, it’s worth looking beyond marketing claims and focusing on a few key fundamentals:

• Meaningful levels of sodium to support hydration
  
• Adequate potassium to support cellular balance
  
• Bioavailable forms of magnesium
  
• A clean, well-considered ingredient profile
  

Some formulations - such as Electrolytes+ - are built around these principles, combining effective doses with well-absorbed forms and a broader mineral profile, rather than relying on minimal inclusions or lower-cost ingredients.
