We scored 31 creatine products sold in the UK. Two use Creapure. Here's what the data actually shows.
“Bulk's Creapure creatine scored 91/100 at £0.17 per serving. The real Creapure premium over the cheapest generic? About 7p per day, or £25 per year. Far less than most people assume.”
We scored nearly 500 supplements across 13 categories and checked every health claim against systematic reviews, meta-analyses, and NHS guidance. Here's what dads in their 30s, 40s, and 50s should be taking — and what they can skip.
“Most UK men are short on at least one key nutrient. Nearly half have below-optimal vitamin D, and the average man gets only about 90% of the recommended magnesium intake. The NHS recommends vitamin D for everyone — and beyond that, the evidence points to five more supplements whose case gets stronger with age: omega-3, magnesium, creatine, zinc, and CoQ10.”
We scored 17 of their best-selling products across 289 real reviews. In a market where 40% of supplements skip third-party testing entirely, Known Nutrition's ISO/GMP/BRC triple certification puts them in a league of their own.
“Known Nutrition scores 100/100 on certifications — the only gummy brand we've profiled to achieve a perfect score. With ISO 9001, GMP, FDA, and BRC accreditation on their gummies, plus HACCP certification on their liposomal liquids, and an average gummy price of just £12.01, this is one of the strongest trust-to-value propositions in UK supplements.”
We scored 14 products from one of Amazon UK's fastest-growing budget supplement brands. The value is real — but so are the gaps.
“Nutrition Geeks averages 69.4/100 overall with strong value scores (81.4/100) but the lowest certification scores (35.4/100) of any brand we've profiled.”
Ranking the UK's top 30 supplement brands by average AI quality score, consistency, and certification coverage.
“Of 53 supplement brands with 3+ products, Garden of Life tops our Trust Index at 87/100 — combining quality, consistency, and certification coverage.”
Dog food and cat food brands ranked by ingredient transparency — named meats vs mysterious 'derivatives'.
“Cat food averages just 37.0/100 on transparency — 29.8 points lower than dog food (66.8/100). 16 pet food products score well overall despite poor transparency.”
Which supplement categories have the worst side effect profiles — and is there a trade-off with effectiveness?
“Pre-Workout & Performance has the worst average side effect score at 65.7/100. Only 226 out of 781 supplements score above 75 on both effectiveness and safety.”
