Beta-alanine: why that tingling is actually proof it is working
The flush, the pins and needles, the warm sensation across the skin — beta-alanine has the most distinctive physical response in sports nutrition. Here is the science behind it.

The truth about building muscle on a calorie deficit — and when it is actually possible
Body recomposition — losing fat while building muscle simultaneously — is real. But it has very specific conditions. Most guides get those conditions wrong.

Collagen for tendons and joints: the supplement that went from joke to evidence-based
Ten years ago collagen was dismissed as expensive gelatine. Then the tendon-loading studies arrived. The story of how a punchline became a protocol.

The overlooked link between cortisol, chronic stress and muscle loss in active people
You are training consistently and eating enough protein. But something is working against you. Cortisol might be the variable nobody measured.

Creatine in 2025: everything you thought you knew that turns out to be wrong
Creatine is the most studied supplement in sports science. It is also the most misunderstood. Time to update your assumptions.

Electrolytes beyond sodium: the hydration mistakes that ruin endurance performance
Drinking more water is not the same as being hydrated. For athletes sweating heavily, plain water can actually make the problem worse.
Pre-Workout & Energy
Why endurance athletes hit the wall — and the nutrition mistake at the root of it
Bonking, hitting the wall, blowing up — every endurance athlete has been there. The mechanism is well understood. The prevention is consistently misapplied.

Fat as fuel: what MCTs actually do for endurance energy, and the hype to ignore
Medium-chain triglycerides are sold as a clean-burning fuel for endurance and focus. The biochemistry is real, but the marketing runs well ahead of the evidence.

What actually happens to your body in the first 30 minutes after a run
The race ends when you cross the finish line. The physiological event continues for another two hours. Understanding it changes how you fuel.

Glutamine: the amino acid working quietly in the background of every hard session
Glutamine does not produce an acute performance buzz. It does not cause visible muscle gain in the short term. What it does is protect the infrastructure that makes training sustainable.

Your gut is part of your training programme — you just never wrote it down
The microbiome influences how you absorb nutrients, how inflamed you are, and how often you get sick. For athletes, that is not wellness talk — that is performance infrastructure.

Intermittent fasting and training: what the actual research shows in 2025
IF has been applied to athletic performance by millions, but was not designed for athletes. The evidence is nuanced and context-dependent.

Joint pain in active people: what is actually happening to your cartilage and how to support it
That nagging knee or shoulder is not just wear and tear you have to accept. Understanding cartilage biology changes how you protect your joints for the long term.

The lactic acid myth and the real science of buffering high-intensity fatigue
Almost everything you were taught about lactic acid is wrong. Understanding what actually causes the burn points to a specific, evidence-backed performance strategy.

Cramps, twitching eyelids and bad sleep: the magnesium story your body keeps telling you
Magnesium is involved in over 300 enzymatic reactions, and athletes lose it faster than anyone. The symptoms of running low are so ordinary that almost nobody connects them.

Mass building after 35: why standard bulking advice is outdated and what to do instead
The aggressive bulk you could manage at 22 is a different equation at 38. The biology has changed. The strategy needs to match.

Why you are not recovering between sessions — and it has nothing to do with sleep
Fatigue that does not resolve with rest is not a sleep problem. It is a nutrition and physiology problem. Here is how to diagnose it.

Omega-3 for athletes: the inflammation dial you are probably not turning
Training success depends on inflammation you can switch on and off. Omega-3 fatty acids are one of the few tools that adjust that switch — if the dose and quality are right.

Is plant-based protein actually enough for serious athletes? What the research says
Plant-based diets in competitive sport are no longer fringe. But the nutrition requirements are genuinely different — and most guides get the details wrong.
Pre-Workout & Energy
Why your pre-workout stops working after 4 weeks (and what to do about it)
The buzz fades. The pump becomes ordinary. The focus blurs. Pre-workout tolerance is a physiological reality — and there is a smart way to manage it.

5 signs your protein intake is too low — that have nothing to do with muscle size
Low protein does not just slow muscle gain. It affects immunity, wound healing, cognitive function and mood. The signals are often misattributed.

Protein myths that are actually costing you muscle — and the ones worth keeping
From the 30g absorption limit to the post-workout window, protein nutrition is drowning in folklore. Here is what the research actually says.

The 48-hour recovery window: why most athletes miss the most important part of their workout
Training hard is only half the equation. What you do in the 48 hours that follow determines whether you actually get stronger — or just tired.

The science of sleep and muscle: what really happens between midnight and 4am
You could optimise every aspect of your training and nutrition and still underperform if you are missing what the body does during deep sleep. Here is what that is.

Strength training for women: the rules that are genuinely different (and the ones that are not)
Women and men are not physiologically identical in their response to training and nutrition. The differences are real, often misapplied, and worth understanding precisely.

What nobody tells you about training after 40 — and the adjustments that actually work
The rules of training do not change after 40. But the physics do. Ignoring the biology is why most people plateau and get injured in their forties.

The quiet epidemic of under-fuelling in recreational sport
Millions of people train hard, eat carefully, and feel worse month after month. The cause is almost never what they think it is.

Vitamin C and the training athlete: immune support, recovery and the antioxidant paradox
Vitamin C is the supplement everyone reaches for at the first sign of a cold. For athletes the picture is more layered — and timing it wrong can blunt your gains.

The indoor athlete problem: why your vitamin D is probably low and what it costs you
You train in a gym, work in an office and live north of Rome. Statistically, your vitamin D is insufficient for half the year — and it is quietly taxing your performance.
