Supplement Dosing & Cost: Whey, Caffeine, Electrolytes (UAE Guide)
The supplement industry is enormous, loud, and full of products that promise far more than they deliver. The good news is that the handful of supplements that genuinely work—whey protein, creatine, caffeine and electrolytes—are well-researched, affordable, and simple to dose correctly. This UAE guide cuts through the marketing to explain how much of each to take, when, and what it should cost, so you spend your money only on what works and use it properly.
Use the dosing calculators linked throughout to set your amounts, then read on.

Whey protein: convenience, not magic
Whey protein is the most popular supplement in any gym, and rightly so—but it's important to understand what it is: simply a convenient source of high-quality protein. It does nothing that food protein doesn't, but it's fast, portable and useful for hitting your daily protein target when whole foods aren't practical.
How much to take
A typical scoop provides a solid dose of protein, and most people use one to two scoops a day to top up their intake—not to replace meals entirely. The right amount depends on how much protein you're getting from food and your total target (1.6–2.2 g per kg of body weight). Our whey protein scoop calculator helps you work out how many scoops you need to fill the gap. Our protein powder duration calculator even tells you how long a tub will last at your usage rate.
Caffeine: the proven performance enhancer
Caffeine is one of the few supplements with strong evidence for improving exercise performance—boosting alertness, reducing perceived effort, and enhancing both endurance and strength output. It's the active ingredient in most pre-workouts.
How much, and the safe limit
An effective performance dose is moderate, taken roughly 30–60 minutes before training. But more is not better, and caffeine has a real safety ceiling—health authorities generally consider up to around 400 mg per day safe for most healthy adults, with individual tolerance varying widely. Exceeding this risks jitters, racing heart, anxiety and poor sleep. Our caffeine intake calculator helps you track your total daily intake (including coffee and tea, which add up fast), and our pre-workout caffeine calculator sets an effective training dose based on your body weight.
Timing and sleep
Caffeine lingers in your system for hours, so afternoon and evening doses can wreck your sleep—which undermines the recovery your training depends on. Keep caffeine to the earlier part of the day, especially if you train in the evening. This matters in the UAE, where evening gym sessions are popular due to the daytime heat.
Creatine: the dosing simplified
Creatine is covered in depth in our dedicated creatine guide, but the dosing essentials belong here too. The standard dose is 3–5 grams of creatine monohydrate daily, taken consistently. You can optionally "load" with around 20 grams per day (split into four doses) for the first week to saturate your muscles faster, or simply start at the maintenance dose and reach the same point in a few weeks. Our creatine loading calculator maps out a loading schedule if you choose that route.
Electrolytes and hydration: critical in the UAE
This is where supplementation becomes genuinely important in the Emirates rather than merely optional. The UAE's intense heat causes heavy sweating, and sweat carries not just water but electrolytes—sodium, potassium and magnesium—essential for muscle function, hydration and performance. Replacing only water after heavy sweating can leave you under-supplied with electrolytes, causing cramps, fatigue and poor performance.
Our electrolyte intake calculator and hydration + electrolytes calculator help you work out your needs based on your activity and sweat losses. For most people doing moderate exercise, a balanced diet and water suffice, but during prolonged or intense training in the heat—common here—deliberate electrolyte replacement makes a real difference to how you feel and perform. This is one supplement category that earns its place specifically because of the UAE climate.
Post-workout nutrition
The hours after training are when your body is primed to recover and adapt. While the "anabolic window" is far wider than the old myth of 30 minutes suggested, getting protein and carbohydrates in after a hard session supports recovery and refuelling. A combination of protein (to repair muscle) and carbs (to replenish energy stores) is the goal—whether from a shake or a meal. Our post-workout nutrition calculator helps you size your post-training intake. There's no need to rush; just don't skip it.
Spending wisely: cost per serving
Supplements vary enormously in price, and marketing often inflates the cost of products that aren't any more effective than cheaper alternatives. The smartest way to evaluate a supplement is by its cost per serving and cost per gram of active ingredient, not the headline price of the tub. Our supplement cost per serving calculator lets you compare products on a like-for-like basis. As a rule, plain creatine monohydrate, standard whey, and basic caffeine deliver the best value—the fundamentals are cheap, and the expensive "advanced" formulas rarely justify their premium.
The honest supplement hierarchy
If you're starting out, here's the truth the industry won't tell you: the vast majority of supplements are unnecessary. The short list with real evidence is creatine, caffeine, whey protein (as a convenience) and, in the UAE heat, electrolytes. Everything else is, at best, marginal. Spend your money on these proven basics and, far more importantly, on the fundamentals that actually drive results—consistent training, adequate protein from food, sufficient calories and good sleep. No supplement compensates for getting those wrong.
