Creatine 2025: Effects, intake & best products in comparison
💥 Creatine 2025: Effects, intake & best products in comparison
Introduction
Creatine is one of the most popular and most researched nutritional supplements in the fitness industry. Whether it's building muscle, increasing strength, or improving recovery, creatine can significantly support your training goals. But how exactly does creatine work? What form is recommended in 2025, and how should you take it correctly?
In this guide you will get all the answers – scientifically sound, SEO-optimized and up to date.
What is creatine anyway?
Creatine is a substance naturally produced by the body that is stored primarily in the muscles. It provides rapid energy during short, intense bursts of exercise—such as strength training or sprinting. Approximately 95% of the body's creatine is found in the muscles.
Our body produces creatine itself (from the amino acids glycine, arginine and methionine), but not in sufficient quantities for performance-oriented athletes – therefore, supplementation with supplements makes sense.
Benefits of creatine – scientifically proven
The effects of creatine have been documented in numerous studies. The most important benefits include:
More muscle strength and performance
Creatine increases ATP (energy) availability, which leads to more repetitions and heavier weights (Buford et al., 2007).
Faster muscle building
Through harder training and increased cell volume, more muscle mass is built in the long term.
Better regeneration
Creatine can reduce inflammation after intense exercise and accelerate the recovery process.
Cognitive benefits
Recent studies show that creatine can also have a positive effect on brain function and concentration (Avgerinos et al., 2018).
How should you take creatine correctly?
Daily dose:
The recommended standard dosage is 3–5 g of creatine monohydrate per day .
Charging phase – yes or no?
Optionally, you can start with a loading phase (20 g/day for 5–7 days) to fill your stores more quickly. However, for many athletes, a constant daily dose is sufficient.
Time of intake:
It's best to consume it with carbohydrates immediately after training – this promotes absorption due to increased insulin levels. It's also recommended on non-training days – ideally in the morning.
Don’t forget to drink water!
Creatine draws water into the muscle cells – so you should drink at least 2.5–3 liters of water every day.
What forms of creatine will be available in 2025?
Creatine monohydrate
The gold standard – scientifically most researched, highly effective, and cost-effective. Particularly soluble in micronized form.
Creatine HCL (hydrochloride)
Better solubility, smaller dosage required – but more expensive and hardly more effective than monohydrate.
Kre-Alkalyn, Ethyl Ester & Co.
Marketing products with partly unproven effectiveness – usually no advantages over monohydrate.
➡️ Conclusion: Creatine monohydrate remains the first choice in 2025 – ideally micronized and tested for purity.
