John Clarke Sports Nutrition Review: What Is Really in the Shilajit Range?
Review at a glance

Our verdict on John Clarke Sports Nutrition in brief

JC Nutrition is a Nottingham brand built by a nutrition and performance coach around three shilajit formats and a long list of goal-based stacks. The capsules are the serious product: a complete label with 50 mg of 10:1 shilajit extract, 25 mg of 10:1 chaga extract, 200 mg of ashwagandha, vitamin D2 at 100 percent of the reference value and vitamin B12 at 200 percent, in a vegan capsule, at £34.99 for 30 servings. The gummies at £24.99 are the easiest format to keep up, and the stacks reach 41 percent off against the sum of their parts.

Two reservations weigh on the score. The best seller publishes no quantity for any of its four actives, and no certificate of analysis is available anywhere on the store: no laboratory is named and no batch links to a report, which is a problem for a mineral resin sold on a purity claim. For an American reader the point is settled before that: the published shipping policy covers the United Kingdom only, with standard delivery at £3.99 and free above £75, and lists no United States service.

Our analysis of John Clarke Sports Nutrition: the formulas under the microscope

This page is an analysis of the official JC Nutrition product pages and policies, not an account of a personal trial. The brand sells only in pounds sterling and its published shipping policy covers the United Kingdom alone, so an American reader cannot order from it today. What follows is what the labels actually say, and where the store stops short of proving what it claims.

The catalog is large for a coach-led brand, with 75 references listed in the all-products collection. Two shilajit formats and one resin carry its reputation, so those are the ones read in detail here.

📌 Super Shilajit Gummies: the best seller, and the least documented

John Clarke Sports Nutrition review: Super Shilajit Gummies

The gummies are the entry point of the range at £24.99, about 34 dollars, or £21.24 on the subscribe and save option, which takes 15 percent off. The serving is two gummies a day, strawberry apple flavor, on a sugar-free base. The published ingredient list is authentic Himalayan shilajit extract, fulvic acid, maca root and ashwagandha, with natural flavorings, described as 100 percent vegan, made in the United Kingdom and third-party tested.

The gap is the dosing. The page gives no quantity for any of the four actives, no extract ratio and no fulvic acid percentage, which makes it impossible to compare the formula with a research dose or a competing label. Anyone taking medication, pregnant or breastfeeding should note the ashwagandha and speak to a doctor first.

📌 Shilajit Capsules: the one formula with real numbers

John Clarke Sports Nutrition shilajit capsules bottle

The capsules are the opposite case and the most transparent product of the range. At £34.99, about 47 dollars, or £29.74 on subscription, the bottle holds 30 servings of two capsules. Each serving lists 50 mg of a 10:1 Himalayan shilajit extract, presented as a 500 mg equivalent, 25 mg of a 10:1 chaga extract presented as a 250 mg equivalent, 200 mg of ashwagandha, 20 micrograms of vitamin D2 at 100 percent of the nutrient reference value and 50 micrograms of vitamin B12 at 200 percent. The shell is a vegetable cellulose capsule, with silicon dioxide as the only excipient.

Two points deserve attention. The extract weights are the small numbers, 50 mg and 25 mg; the 500 mg and 250 mg figures are raw-material equivalents. And the chaga is here, in the capsules, not in the gummies: the two products are often described as if they shared one formula, and they do not. The authorized claims that apply are those of the two vitamins, not the range's broader energy and testosterone language.

📌 Shilajit Resin: 30 grams, and a purity claim without a document

The resin sits at the same £34.99 as the capsules, £29.74 on subscription, for a 30 gram jar presented as a two-month supply at 600 mg a day, roughly a pea-sized amount, or about 50 servings. The page describes shilajit freshly harvested at 16,000 feet in the Himalayas, rich in up to 85 trace minerals, containing fulvic acid and humic compounds.

What is missing is the measurement: no fulvic acid percentage, no identity or purity result, no batch document. The page states that the resin has been safety tested by a professional organization and contains no heavy metals, fillers or additives, which is precisely the assertion a certificate of analysis exists to support. For a mineral resin, that document is the whole quality argument.

The verdict on format and dosing

Three formats for the same core ingredient is a genuine strength: a gummy for people who will not swallow capsules, a capsule for a defined serving, a resin for the traditional form. The capsule is the one to choose if the dose matters, because it is the only one that publishes numbers. The resin is the best value per serving on paper, around 70 pence a day for 50 servings, but it is dosed by eye.

The commercial arithmetic is worth doing before using any code. Subscribe and save takes 15 percent off with a two-cycle minimum, the LMC code takes 10 percent off a one-time order with no commitment, and the stacks reach 41 percent. A permanent clearance section and a separate buy-one-get-one listing on the capsules mean the code is rarely the largest discount on the same basket.

Effectiveness and what to expect

The brand-stated positioning is energy, performance and vitality; what can be supported is narrower. Vitamin B12 contributes to the reduction of tiredness and fatigue and vitamin D2 to normal immune function and the maintenance of normal bones. Shilajit and chaga are traditionally used ingredients studied for those areas, with no authorized health claim, and ashwagandha is an adaptogen studied for stress, again with none.

Everything above the vitamins is therefore a matter of ingredient tradition and ongoing research, not a promised result, and the range's testosterone and weight-management vocabulary makes that reminder more important here than elsewhere. Anyone on medication, managing thyroid, liver, autoimmune or blood-pressure conditions, pregnant or breastfeeding should have the label checked by a doctor or a pharmacist first, and competitive athletes need batch-level banned-substance certification rather than a general testing statement.

Who is John Clarke Sports Nutrition?

The brand, also presented as JC Nutrition, is run from Nottingham, at Suite 99, 1 Hanley Street, NG1 5BL. It was created by John Clarke, a nutrition and performance coach, and the store's footer sums the positioning up in three claims: made by a nutritionist, third-party tested, made in the UK.

On reputation, two figures circulate and should not be confused. The Trustpilot profile is claimed by the company and shows 4.4 out of 5 across 81 reviews, with 90 percent at five stars. The badge on the product pages is the store's own on-site widget, at 4.91 out of 5 across 645 reviews. The independent figure is the Trustpilot one.

📌 Key commitments

  • Formulas presented as designed by a nutrition and performance coach, made in the United Kingdom
  • Vegan formats throughout, with vegetable cellulose capsules and sugar-free gummy bases
  • Third-party testing stated by the brand on every batch, with no certificate published on the site
  • Subscribe and save at 15 percent off, with a two-billing-cycle minimum
  • UK-only shipping, free above £75, and 30-day returns on unopened products

Super Shilajit Gummies against a standard shilajit resin

Criteria
Analyzed by TBS Super Shilajit Gummies
Standard shilajit resin
Format and dosing ❌Dosed by eye, a pea-sized amount daily
Published amounts ✅Weight per jar and daily dose usually stated
Certificate of analysis ✅Serious resin brands publish a batch report
Taste and sugar ❌Bitter and tarry, dissolved in a hot drink
Price ✅£34.99 for the brand's own 30 g jar, about 50 servings
Ships to the United States ✅Many US resin brands ship domestically

The table sets out the real trade-off. The gummy wins on everything to do with taking the product every day: no spoon, no bitterness, a fixed serving, a lower monthly price. The resin wins on knowing what you are taking, because a jar sold by weight forces a stated quantity while a flavored gummy does not. The last line ends the discussion for an American reader.

The John Clarke Sports Nutrition range

John Clarke Sports Nutrition Playboy Stack supplement range

The store lists 75 references. Around the three shilajit products sit Alpha Capsules at £34.99, Tribulus Capsules at £29.99, ZMA Capsules at £23.99, Creatine Gummies at £29.99, Test+ Gummies at £24.99, Whey Protein Advanced at £59.99, NMN+ Resveratrol at £39.99, JC Liquid Lions Mane 2000 mg at £29.99 and Sea Moss Gummies at £23.99.

Weight management is a section of its own, built around the Suppressa GLP-1 line, capsules at £36.99, gummies at £29.99 and drops at £39.99, alongside Carb Cut and Extreme Fat Burning products at £34.99 to £37.99.

John Clarke Sports Nutrition Invincible Stack supplements

Then come the goal-based stacks, which carry the largest discounts on the store: the Test Rebuild Protocol Stack at £89.99 against a combined value of £153.95, displayed as 41 percent off, The Playboy Stack at £88.99 against £129.75 and The Invincible Stack at £79.99 against £120.95. Those savings hold up against the sum of the individual prices, and they create the main risk of the range: a stack combines several finished products, so actives can be duplicated across bottles. Read every label separately, and keep the naming in perspective, since a stack called TRT is not testosterone replacement therapy and the Suppressa GLP-1 line is not a prescription medicine, which the brand states itself.

Composition breakdown: what the formulas are actually made of

Shilajit, chaga and the extract-ratio trap

The capsule label shows how the whole range writes its numbers. Fifty milligrams of a 10:1 shilajit extract means 50 mg of concentrated extract obtained from 500 mg of raw material; the 500 mg figure describes the starting material, not what is in the capsule. The same applies to the 25 mg of 10:1 chaga extract shown as 250 mg. The notation is standard and legitimate, and it is also the easiest number on a label to misread.

What no page provides is the marker that would make those extracts comparable: no fulvic acid percentage for the shilajit, no beta-glucan content for the chaga, no withanolide percentage for the ashwagandha. Without a marker, a 10:1 ratio says how much raw material was used, not how much active compound reached the finished product.

The vitamins, and what the brand does not publish

The two vitamins in the capsules are the only ingredients with a legally comparable dose: 20 micrograms of vitamin D2, exactly 100 percent of the nutrient reference value, and 50 micrograms of vitamin B12, 200 percent of it. Note the form, D2 rather than D3, the plant-compatible choice consistent with the vegan claim and generally considered less efficient at raising blood levels.

Beyond that, the documentation stops. The site states third-party testing on every batch, but no laboratory is named, no certificate of analysis is downloadable and no batch number links to a report. For shilajit that is the single document that would justify the purity claim, and it is the brand's clearest area for improvement.

Buying John Clarke Sports Nutrition from the United States

John Clarke Sports Nutrition does not ship to the United States. The published shipping policy is headed domestic shipping, United Kingdom only, and lists no international service. Inside the United Kingdom, orders are processed within one to two business days, with a 4 pm cut-off, then standard delivery costs £3.99 for three to five business days, express £5.99 for one to three days and priority £9.99 for one to two, free above £75. Prices are in pounds sterling only.

The return terms matter as much as the delivery ones. Returns are accepted within 30 days of delivery, and the product must reach the warehouse unopened, unused and sealed; opened supplements are not returnable. The customer pays the return postage plus a £6 processing charge, and refunds are issued within 10 business days of approval. An American reader should treat this page as a benchmark for what a shilajit label ought to disclose, then buy from a brand that ships domestically and publishes a batch certificate.

Technical analysis and expert verdict

The strengths are consistent: three formats of the same ingredient family, one of which publishes a complete label with extract ratios and nutrient reference values, vegan formulations throughout, UK manufacturing, clear pound pricing and a subscription that genuinely undercuts the promo code. The capsule formula is coherent, with shilajit and chaga for the traditional-use part, ashwagandha as the adaptogen, and two vitamins carrying the only claims the label can legally make.

The limits are equally clear. The best seller publishes not a single quantity, and no certificate of analysis is available anywhere on the site, which sits awkwardly with a purity claim on a mineral resin. Parts of the catalog use outcome language, around testosterone and GLP-1 in particular, that goes beyond what a food supplement can promise. The LMC code takes 10 percent off an eligible one-time order, but the subscription and the stacks are usually the better deal, and none of it is reachable from the United States.

The John Clarke Sports Nutrition flagship products

📌 Super Shilajit Gummies

John Clarke Sports Nutrition review: Super Shilajit Gummies

The brand's best seller: two gummies a day on a sugar-free strawberry apple base, with Himalayan shilajit extract, fulvic acid, maca root and ashwagandha, described as 100 percent vegan, made in the United Kingdom and third-party tested. £24.99 for a one-time purchase, about 34 dollars, or £21.24 on the subscribe and save option. The page publishes no quantity for any of the four actives, which is the reservation to keep in mind.

📌 Shilajit Capsules

John Clarke Sports Nutrition shilajit capsules bottle

The documented alternative, and the one to choose if the dose matters: 30 servings of two capsules at £34.99, about 47 dollars, or £29.74 on subscription. Each serving states 50 mg of 10:1 shilajit extract as a 500 mg equivalent, 25 mg of 10:1 chaga extract as a 250 mg equivalent, 200 mg of ashwagandha, 20 micrograms of vitamin D2 and 50 micrograms of vitamin B12, in a vegetable cellulose capsule.

The LMC code takes 10 percent off an eligible one-time order on the official store, in the United Kingdom, which it serves exclusively. Compare it against the 15 percent subscription and the stack pricing before choosing.

Our final verdict: should you buy from John Clarke Sports Nutrition?

My final score:
6.7
/10
John Clarke Sports Nutrition is a credible British brand when you buy the right product from it. The Shilajit Capsules publish a complete label, with 50 mg of 10:1 shilajit extract, 25 mg of 10:1 chaga extract, 200 mg of ashwagandha and two vitamins at 100 and 200 percent of the reference values, for £34.99 and 30 servings. The gummies are easier to keep up but disclose no quantity at all, and no certificate of analysis is published anywhere on the store, which is the brand's real weak point on a mineral resin. And the shipping policy is United Kingdom only, so American readers cannot order from it today.
