Elite supplements, tested and rated — the ones I actually use.
As an endurance athlete who sweats heavily during long rides, magnesium depletion is a real performance limiter. The bisglycinate form is chelated, bound to the amino acid glycine, which significantly increases bioavailability compared to cheaper forms like magnesium oxide. It supports normal muscle function and energy metabolism, and the calming effect on the nervous system makes it ideal before sleep, when recovery actually happens.
After a hard interval session or a race, your muscles need fast-available amino acids. With 90% protein content and no fat, lactose or sugar, Whey Isolate is as clean as it gets. The rapid digestion and absorption rate makes it the go-to post-training protein, and the leucine content triggers muscle protein synthesis within minutes of ingestion.
One of the best-researched supplements available. EPA and DHA, the two active fatty acids in fish oil, reduce systemic inflammation, which is especially relevant for athletes under high training loads. Long-term, they support cardiovascular health and immune function, both critical when you're racing at Category A/B level.
Where Whey is fast, Casein is slow. The amino acids from Casein Isolate are released continuously into the bloodstream over 7–8 hours, making it ideal before sleep. With 95% protein and virtually no fat or sugar, it keeps your muscles fed overnight without extra calories. Try it as a protein pudding: mix with pudding powder and your milk of choice, pour into a bowl, top with frozen berries, wait a few minutes, enjoy.
Your gut microbiome influences far more than digestion. It plays a direct role in immune function, inflammation regulation, and even energy availability. Inulin is a prebiotic fibre that selectively feeds beneficial gut bacteria, supporting a healthy microbiome from the ground up. Especially relevant when training load is high and immune resilience matters.
Mid-race energy that's easy to dose and fast to act. Caffeine enhances fat oxidation and reduces perceived effort, both well-documented in endurance sports research. The key advantage of a gel format is the precise, controlled dose you can time to your effort peaks.
Caffeine reaches peak plasma concentration roughly 30–60 minutes after ingestion. An Activate Shot right before the start line is timed precisely to hit that window, maximising the ergogenic effect when it counts most, at the gun.
Carbohydrates are the primary fuel source at high intensities, and maltodextrin is one of the most efficient ways to deliver them. The gut can absorb up to 60g of carbohydrates per hour via the glucose transporter, and maltodextrin hits that pathway fast. Skip it during long efforts and you're leaving performance on the table, plain and simple. Mix it into your bottle, your gel, or your race nutrition and keep the engine running.
