John Clarke Sports Nutrition review: performance supplements from the UK

John Clarke Sports Nutrition, now presented as JC Nutrition, is a British brand created by nutrition and performance coach John Clarke. The official site says his product decisions draw on more than 25 years of coaching experience. The catalog spans sports performance, weight management, general wellness, sleep, digestion, menopause, and bundled programs.

The range is easy to browse by goal, but shoppers should separate coaching experience and marketing language from finished-product clinical evidence. Terms such as GLP-1 inspired, testosterone support, and natural energy describe positioning, not equivalence to prescription treatment or a guaranteed result.

What does JC Nutrition sell?

The store combines individual supplements with multi-product stacks and subscriptions. Current categories include:

• Shilajit, adaptogen, vitamin, and mineral formulas
• Creatine, pre-workout, muscle-building, and recovery products
• Suppressa and other appetite or weight-management combinations
• Sleep, digestive, cardiovascular, menopause, and beauty formulas
• Goal-based bundles containing several products

Stacks make it easier to duplicate ingredients or take more products than necessary. Review every label individually instead of assuming that products in the same bundle are automatically appropriate together.

Super Shilajit Gummies at a glance

Super Shilajit Gummies are listed among the brand's best sellers. A bottle is priced at £24.99, about $34, as a one-time purchase, with a 15% subscription price of £21.24, about $29, and a minimum commitment of two billing cycles. The suggested serving is two gummies per day, preferably in the morning or before physical activity.

The product page lists Himalayan shilajit extract, fulvic acid, maca, ashwagandha, natural flavoring, and a sugar-free gummy base. It describes the gummies as vegan, made in the UK, and third-party tested. However, the visible product copy does not provide exact amounts for the main active ingredients. Without those quantities, buyers cannot compare the formula precisely with research doses or competing labels.

How useful are the testing claims?

JC Nutrition states that every batch is independently tested, but no certificate of analysis is downloadable on the store and no testing laboratory is named. That is a positive policy when a report identifies the actual product, batch, test date, laboratory, methods, and measured results. Some pages still contain template language asking for product-specific COA information to be added, and no batch number on the site links to a report.

• Request a downloadable report for the exact batch being purchased.
• For shilajit, look for measured lead, arsenic, cadmium, mercury, and identity or purity results.
• Competitive athletes should require credible batch-level banned-substance certification, not a general marketing statement.
• Check active quantities and all other ingredients on the delivered label.

A GMP or third-party-tested statement is not proof that a supplement produces its advertised benefit. Testing can confirm selected quality parameters only when the underlying report is complete and applicable.

Safety and realistic expectations

Shilajit gummies should not be expected to correct fatigue, low testosterone, hormonal symptoms, or cognitive problems without identifying their cause. Ashwagandha and other botanicals may be unsuitable during pregnancy and can interact with thyroid, sedative, immune, glucose, or blood-pressure treatments. Purified, contaminant-tested shilajit is particularly important.

The brand correctly says its Suppressa products are not GLP-1 drugs. They should not be presented as substitutes for semaglutide, tirzepatide, medical weight-loss care, or a balanced diet. Anyone using medication, managing a condition, preparing for surgery, or combining several formulas should review the complete labels with a clinician or pharmacist.

Price and John Clarke Sports Nutrition promo code

The Super Shilajit Gummies are priced at £24.99, approximately $33.94. Code LMC may reduce an eligible one-time order by 10%, bringing it to about £22.49, roughly $30.55, before shipping and currency-card costs. It may not combine with the existing 15% subscription offer or another promotion, so checkout determines the final total.

Shipping and returns

The official shipping policy currently describes domestic UK shipping only. Orders are processed within one to two business days; standard UK delivery is estimated at three to five business days after processing and costs £3.99, about $5.39, with free standard shipping over £75, about $101. US delivery is not listed, so American buyers should not assume that the store will accept their address.

Unopened, unused supplements in sealed packaging may be returned, but they must reach the warehouse within 30 days of delivery. Customers pay return postage, and the policy lists a £6, about $8.10, processing charge plus £1, about $1.35, for each additional item. Opened supplements are ineligible.

Our verdict

JC Nutrition offers a broad UK catalog, clear base pricing, and a stated commitment to independent testing. The main drawbacks are incomplete public detail on some active doses and certificates, aggressive outcome language in parts of the range, and no official US shipping option. Super Shilajit Gummies are most suitable for buyers who can inspect a lot-specific report and full label before purchase.
