Creatine and Protein: Which Form to Choose and How to Take

Creatine and protein are the most studied and effective sports supplements, yet many myths surround them: "which creatine is best", whether loading is needed, which protein to choose. There is also an important medical nuance — creatine skews the creatinine test. Let's break down which form of creatine and protein to choose, how to take them, and what to keep in mind.

Why Creatine and Protein

• Creatine — increases the muscle energy store (phosphocreatine): more strength and reps, gains in lean mass. One of the few supplements with a very strong evidence base; there is also data on cognitive benefit.
• Protein — simply a convenient source of protein to meet your daily target, important for muscle growth and recovery. Not "magic", just topping up protein.

Creatine: Which Form Is Best (Monohydrate)

Despite dozens of "new" forms (hydrochloride, malate, kre-alkalyn), creatine monohydrate remains the gold standard: the most studied, effective, and cheap. There is no point overpaying for "advanced" forms — they do not outperform monohydrate.

How to Take Creatine (Loading or Not)

Two working options:

• With loading: ~0.3 g/kg of body weight per day for 5–7 days, then 3–5 g/day maintenance — saturates muscles faster.
• Without loading: 3–5 g/day from the start — the same end result, but saturation in 3–4 weeks.

Timing is non-critical; take it daily, including non-training days. Drink enough water with it.

Creatine and the Creatinine Test (Worth Knowing)

A practical nuance: taking creatine raises blood creatinine — a normal consequence, not a sign of kidney disease. If you take a kidney function test, tell the doctor about creatine, otherwise a slightly elevated creatinine may be mistaken for a problem. In healthy kidneys, creatine is safe.

Protein: Whey, Casein, Isolate

• Whey concentrate — fast, versatile, best value.
• Isolate — more purified, less lactose and carbs; for lactose intolerance and "cutting".
• Casein — slow, convenient at night.
• Plant-based (soy, pea) — for vegans; combined for a complete amino acid profile.

Choose by tolerability, goal, and budget; for most, whey concentrate is enough.

How Much Protein You Actually Need

A benchmark for active people is about 1.6–2.2 g of protein per kg of body weight per day, and this can be met with food; protein powder just conveniently tops up the target. "More protein, more muscle" is a myth: excess protein beyond your needs does not turn into muscle.

Safety and Myths

• "Creatine harms the kidneys" — not confirmed in healthy kidneys; it only affects the creatinine number on a test
• "Protein harms the kidneys/liver" — not confirmed in healthy people
• "You need expensive creatine forms" — no, monohydrate

Matching sports supplements to your goals and labs is helped by supplement matching by your tests.
