Editor's Note
Balance Journal's electrolytes roundup puts 22 brands through the same formulation check, and Puresport earned its place in that line-up without a personal visit or a taste test. James Bellis, who carries out this review, is SCA-certified as a barista, which is not a nutrition or clinical qualification. Nothing here is medical advice, dosing guidance or a treatment claim. Clemmie Rose, a Nutritional Therapist and BANT member, reviewed this article for accuracy.
The Verdict on Puresport, in One Paragraph
“A sugar-free, Informed Sport-certified sachet with a real UK retail footprint. It will not say where its salt comes from, and that keeps it sixth.”

Frequently Asked Questions
Are Puresport electrolytes good?
On our published formulation-purity framework, Puresport ranks sixth of 22 UK electrolyte brands. Ultra Electrolytes is Informed Sport certified, sugar-free and stevia-sweetened, with seven confirmed ingredients. It scores well on label transparency and retail availability, but loses ground for not naming its salt source, unlike three of the five brands ranked above it.
When should you drink Puresport electrolytes?
Puresport positions Ultra Electrolytes at athletes and people with heavy sweat loss, and the 1,000mg sodium dose reflects that positioning rather than casual daily sipping. The brand's own product page says to use it before training, during long or hot sessions, or afterwards. It describes the formula as built for demanding conditions, not for a desk-bound day.
What are the benefits of taking Puresport electrolytes?
Puresport describes each sachet as replacing sodium, potassium, magnesium and calcium lost through sweat, minerals that appear in EFSA's dietary reference values. It carries no sugar or added calories. This review makes no claim that it improves energy, performance or health, and it is not a treatment for any condition.
Why shouldn't you drink electrolytes every day?
Most people on a normal UK diet already get enough sodium from food, so a daily 1,000mg sachet stacks on top of existing intake rather than replacing it. NHS and EFSA guidance both frame it this way. Daily use suits heavy training or sweat loss far more than normal eating.
Is Puresport an UK company?
Yes. Puresport was founded in the UK in 2019 by Grayson Hart and a co-founder named Adam, and its Trustpilot profile lists its registered contact as the United Kingdom. It sells direct from puresport.co and is stocked at UK retailers including Boots and Amazon UK.
Who owns Puresport?
Daniel Temm is the brand's documented current CEO. Grayson Hart co-founded Puresport with Adam Ashe in 2019, launching with an Informed Sport certified CBD oil before the brand expanded into electrolytes and other supplements. Hart stepped down as CEO and director in November 2023, by his own public statement.
Does Puresport offer an NHS discount?
No NHS or healthcare-worker scheme is published on Puresport's own site. Its site does advertise 10% off for newsletter sign-ups, and that applies to full-price products only (puresport.co lab reports page, checked 2026-10-04). Check the checkout for the current terms before you buy, as the offer can change.
Does Informed Sport certification mean Puresport is tested for heavy metals?
No. Informed Sport tests finished batches for substances banned in competitive sport, such as stimulants and anabolic agents. It does not test for heavy metals, PFAS or sweetener safety. Puresport's Ultra Electrolytes carries the certification, confirmed on Informed Sport's own directory - a doping screen, not a purity test.
Is 1,000mg of sodium too much for daily use?
It depends on diet and activity level. Most people on a normal UK diet already get sodium from food, so a 1,000mg sachet adds to existing intake rather than replacing it. The brand positions the dose at heavy sweat loss.
Puresport vs Precision Hydration: which is better value?
Precision PH1000 costs about 90p per tablet (£8.99 for a 10-tablet tube, precisionhydration.com, checked 2026-10-04) and each tablet carries 500mg of sodium, so 1,000mg costs about £1.80. Puresport's sachet delivers 1,000mg for 77p on subscription or £1.10 one-time. Both rely on Informed Sport certification rather than published heavy-metal testing, and Puresport is cheaper per 1,000mg of sodium on both routes.
