Lean X was created with one purpose: provide weight-management support that is anchored in peer-reviewed evidence and fully aligned with UK / EU health-claim regulations. Below is a concise yet transparent walk-through of each key ingredient, complete with PubMed links so you can explore the data yourself.

🔎 Methodology & Literature Selection
- Peer-review only: randomised controlled human trials, systematic reviews, and meta-analyses.
- Recency: preference for studies published within the past ten years, provided they are methodologically sound.
- Evidence weight: RCTs are prioritised over observational studies and animal work.
Each paper is assessed by our in-house Nutrition Scientist (RNutr, PhD) and logged in an internal evidence matrix.
⚡️ β-Hydroxybutyrate Salts (BHB)
🧾 Snapshot
BHB is the predominant ketone body produced when carbohydrate availability drops. Orally supplied BHB can appear in blood within 15-30 minutes.
⚖️ Why It Matters for Weight Control
- Appetite signal: Nutritional ketosis is linked to lower ghrelin and reduced subjective hunger.
- Cognitive fuel: BHB crosses the blood-brain barrier, providing efficient energy during calorie restriction.
| Study | Design & Population | Main Finding |
|---|---|---|
| Stubbs et al., 2018 PMID 29105987 | Crossover, n = 15, ketone drink vs. isoenergetic control | BHB spike lowered ghrelin (-30 %) and “desire to eat” for up to 4 h post-dose |
| Gibson et al., 2020 PMID 32193016 | Systematic review, 10 RCTs | Consistent reduction in subjective appetite under exogenous ketosis |
Health-claim note: There is no authorised weight-loss claim for BHB; Lean X positions BHB solely as an alternative energy source.
🧲 Magnesium (as Magnesium-BHB)
Authorised claim (EU Register): Magnesium contributes to normal energy-yielding metabolism. It acts as a co-factor in over 300 enzyme reactions, including β-oxidation and ATP synthesis.
Key evidence: Cuciureanu & Vink 2011 – review on magnesium and metabolic flexibility. Rosanoff et al. 2022 – meta-analysis linking higher magnesium intake with improved glucose handling (PMID 35362196).
🦴 Calcium (as Calcium-BHB)
Authorised claim: Calcium is needed for the maintenance of normal bones. In a ketogenic context, calcium offsets potential shortfalls when dairy and cereals are reduced.
Study: Zemel et al., 2009 – RCT (n = 32): calcium-rich, calorie-restricted diet led to greater fat-mass reduction vs. control (PMID 19540390).
💧 Sodium (as Sodium-BHB)
Sodium stabilises the BHB solution and improves palatability. Each serving of Lean X delivers under 200 mg Na—well below the gov.uk guideline (< 2 g/day).
📊 Evidence at a Glance
- BHB raises blood ketones within 30 minutes and may blunt hunger cues.
- Magnesium supports normal energy metabolism—crucial during a calorie deficit.
- Calcium covers common gaps in low-carb or ketogenic eating patterns.
🛠️ Practical Implementation
Taking Lean X before a main meal delivers a moderate ketone rise during the critical post-meal snack window—often the point where diets fall off track.
