PerforMelon® – what is it and why is it used in dietary supplements?
PerforMelon® is a patented watermelon powder used in dietary supplements to deliver natural citrulline and electrolytes. It is derived from the whole watermelon – both flesh and rind – and standardized for a consistent content of bioactive compounds.
But what makes watermelon so interesting from a dietary supplement perspective? And why does Skytrition choose to use PerforMelon® in HydraUP?
Here, we cover everything you need to know.
What is PerforMelon®?
PerforMelon® is a patented and standardized watermelon powder, developed by Compound Solutions. It is derived from the entire watermelon – including the rind – which is important because the watermelon rind contains higher concentrations of citrulline than the flesh.
The result is a natural watermelon extract that delivers:
- Natural L-citrulline – an amino acid that plays an important role in nitric oxide production
- Natural electrolytes – potassium, magnesium, and sodium from the watermelon
- Lycopene – an antioxidant that occurs naturally in watermelon
- Natural sugars and carbohydrates – in small amounts from the fruit
What is citrulline and why is it interesting?
Citrulline is a non-essential amino acid that is naturally produced in the body and found in watermelon. In the body, citrulline is converted into arginine, which in turn is a precursor to nitric oxide (NO).
Nitric oxide is known for its role in dilating blood vessels (vasodilation), which increases blood flow to the muscles. This is why citrulline is a common ingredient in pump-focused dietary supplements.
PerforMelon® delivers citrulline in its natural form from watermelon, unlike the synthetic L-citrulline or citrulline malate used in many pre-workout products.
PerforMelon® compared to synthetic citrulline
There are two main ways to get citrulline in a dietary supplement:
- Synthetic L-citrulline or citrulline malate – highly concentrated, common in pre-workout products in doses of 6–8 g
- PerforMelon® – natural citrulline from watermelon, lower dose but in a natural matrix form with electrolytes and antioxidants
PerforMelon® is not a substitute for high-dose citrulline in a pre-workout formula, but rather a complement that contributes natural citrulline along with electrolytes and lycopene in a hydration product.
Watermelon and hydration
Watermelon consists of over 90% water and is a natural source of electrolytes. This is why watermelon has traditionally been used as a natural hydration option – especially in hot climates and after physical activity.
PerforMelon® concentrates these properties into powder form, making it easy to include in dietary supplements without all the fluid content.
When is it best to take PerforMelon®?
Since PerforMelon® is included in HydraUP – an electrolyte product – it is best suited for:
- Before training – to ensure good hydration before the session
- During training – to replenish electrolytes and fluids
- After training – as part of the recovery routine
- Daily – as natural hydration support

In which Skytrition products is PerforMelon® found?
PerforMelon® is used in:
- HydraUP – Electrolytes – a dedicated electrolyte product with CocoMineral®, GlycerSize™, AstraGin®, and PerforMelon® for complete hydration
What should you consider when choosing products with PerforMelon®?
1. The holistic nature of the hydration formula
PerforMelon® is part of a larger electrolyte matrix. Look at the entire formula – which electrolytes are included and in what amounts.
2. Natural vs. synthetic citrulline
If your primary goal is a maximum pump, high-dose synthetic citrulline (6–8 g) is recommended. PerforMelon® contributes natural citrulline in a hydration context.
3. Taste and natural substances
PerforMelon® also contributes a natural watermelon taste and aroma, making it a popular ingredient in hydration products.
Frequently asked questions about PerforMelon®
What is PerforMelon® made of?
PerforMelon® is a patented powder from the whole watermelon, including the rind, standardized for natural citrulline and electrolytes.
Does PerforMelon® contain citrulline?
Yes, PerforMelon® contains natural L-citrulline from watermelon. The concentration is lower than in synthetic citrulline but is delivered in a natural matrix form.
Why is watermelon rind used in PerforMelon®?
The watermelon rind contains higher concentrations of citrulline than the flesh. By using the whole fruit, the citrulline content is maximized.
In which Skytrition products is PerforMelon® found?
PerforMelon® is included in HydraUP.
Is PerforMelon® natural?
Yes, PerforMelon® is a natural extract from watermelon.
Summary
PerforMelon® is a patented watermelon powder that delivers natural citrulline, electrolytes, and lycopene in a concentrated form. It is used in Skytrition’s HydraUP as part of the electrolyte and hydration matrix.
PerforMelon® is not a substitute for high-dose citrulline in a pre-workout, but a natural complement in a hydration product – just as watermelon has traditionally been used for hydration after physical activity.
