An electrolyte powder with amino acids combines minerals such as sodium and potassium with one or more amino acids — commonly things like citrulline, beta-alanine, taurine, glutamine, tyrosine or branched-chain amino acids. The combination isn't rare any more. What varies is how clearly each product tells you what you're getting: which amino acids, in what form, and how much of each.
Here's how to compare them, and exactly what's in Nuviita Performance Electrolytes.
Check 1: Can you see every individual dose?
Some products list each amino acid with its own amount. Others group them under a "blend" or "complex" with one total figure. A single total tells you the blend weighs, say, 3g — but not whether that's mostly one ingredient with a trace of the rest.
If you want to know what you're taking, look for a label that lists every ingredient with its own milligram figure.
Check 2: Which form does the label specify?
The form changes the number that matters. Citrulline is a good example: many products use citrulline malate, often in a 2:1 ratio, which means roughly two-thirds of the weight is citrulline and one-third is malic acid. So 1,200mg of L-citrulline malate 2:1 contains roughly 800mg of citrulline. Neither number is wrong — they just describe different things, so compare like with like.
Check 3: What does the product claim, and on what basis?
In Great Britain, a food or supplement can only make a specific health claim if that claim is on the GB nutrition and health claims register, with the wording and conditions it sets. Several minerals common in electrolyte powders have authorised claims. None of the five amino acids in Nuviita's formula — citrulline, beta-alanine, taurine, tyrosine and glutamine — has one.
That's why, in our own content, we tell you what's in each sachet and how much, rather than what each amino acid does. When you see a strong benefit promise attached to an ingredient, it's reasonable to ask what supports it.
Check 4: How do the amounts compare with standalone supplements?
Amino acids in an electrolyte drink are usually present in smaller amounts than in a dedicated single-ingredient supplement. For example, the International Society of Sports Nutrition's position stand on beta-alanine describes research using 4–6g per day; Nuviita contains 600mg per sachet. Treat an amino complex in an electrolyte drink as part of that drink's formula — not as a replacement for a standalone supplement you've chosen for a specific reason.
How electrolyte + amino acid powders typically compare
No competitor products are named here — ASA rules prevent Nuviita naming competitors in its own content.
| What to compare | Why it matters | What you'll typically see | Nuviita Performance Electrolytes |
|---|---|---|---|
| Individual amino doses | Whether you can see what you're taking | Individual amounts, or one "blend" total | Every dose listed |
| Amino acids included | They vary a lot between products | Often 1–5, sometimes BCAAs or EAAs | 5: L-citrulline malate (2:1), beta-alanine, L-glutamine, taurine, L-tyrosine |
| Sodium per serving | The main electrolyte lost in sweat | Commonly 300mg–1,000mg+ | 560mg |
| Sugars per serving | Many hydration + amino products are sugar-free | 0g to several grams | 0g |
| Price per serving | Matters for regular use | Commonly ~50p to £1.50+ | ~£1.00 (£24.95 ÷ 25 sachets) |
Typical ranges are general observations from publicly available UK product information (2026), not a verified market audit or a claim about any named product.

FAQ
What is an electrolyte powder with amino acids?
A drink mix that combines minerals such as sodium and potassium with one or more amino acids, such as citrulline, beta-alanine or taurine.
How do I know how much of each amino acid I'm getting?
Look for a label that lists each amino acid with its own amount, rather than one total for a "blend".
What does "L-citrulline malate 2:1" mean?
Two parts citrulline to one part malic acid, so roughly two-thirds of the listed weight is citrulline.
Do amino acids in electrolyte drinks have authorised health claims in the UK?
Not the five in Nuviita's formula. Authorised claims are listed on the GB nutrition and health claims register.
Which amino acids are in Nuviita?
L-citrulline malate (2:1) 1,200mg, beta-alanine 600mg, L-glutamine 500mg, taurine 400mg and L-tyrosine 250mg per sachet.
Food supplements should not replace a balanced diet.
