Can high-protein supplement intake cause foamy urine in men?

Question

Hello doctor,

I am 24 years old, a male. Two months ago, I joined the gym and have not taken any steroids. What I have taken is balanced protein and creatine, within the range of 100 to 110 grams of protein daily (sometimes I am not able to fulfil this and eat less protein, but I do not exceed that amount) and three to four grams of Creatine (many times not taken).

Other than that, I am taking fish oil, magnesium, and vitamin D3 with K2 within limits, like one tablet, and also not taking it daily (taken on alternate days and often skipped). I am also taking oats, peanut butter, ghee sometimes, almonds, walnuts, and pumpkin and sunflower seeds, along with chia seeds, all in soaked form. I take eggs, fish, and sometimes chicken, but within a limit.

However, four to five days ago, I noticed in my toilet that I was having foamy and bubbly urine each time I urinate. There is no pain, no colour change, and no abnormal feelings like swelling. But I still worried a lot and have done a complete body health check-up along with the creatinine albumin ratio and Cystatin C.

The results came, and everything was normal except Cystatin C. Here are the values:

Cystatin C: 1.11 mg/L.
Bilirubin: 1.36 mg/dL.
Vitamin D: 20.8 ng/mL.
LDL cholesterol: 1.09 mmol/L.
Sodium (electrolyte): 135.08 mEq/L.
Blood pressure: 138/78 mmHg.

I am very worried about this issue, and I searched online, and got to know that everything is normal, that I should just drink more water and stay relaxed, and after some days it will be normal. So please, doctor, tell me what happened to me and what the root cause of this issue is, and what the solution is. If you want, I can share all my test reports.

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

I completely understand that this issue has been worrying you. It is completely normal to feel concerned when you notice foamy urine; many people experience something similar. I am here to help you figure this out step by step.

Based on your description, this foamy urine is most likely temporary and related to high protein intake and supplements. This means that when you consume more protein or your body is slightly dehydrated, a bit of foam in the urine can appear. Usually, it is not dangerous if other kidney-related symptoms or tests are normal.

Here is what I suggest you do right now:

Drink enough water, at least 0.53 to 0.79 gallons per day, to help dilute your urine.
Keep your protein and supplement intake balanced and give your body some time to adjust.
Keep an eye on your urine for a few days. If you want extra reassurance, you could do a 24-hour urine protein test or a kidney ultrasound.
Try to avoid overconsuming protein or ignoring new symptoms, because this can put extra stress on your kidneys.

Please seek medical help sooner if you notice any of these:

Unusual swelling in the hands, feet, or face.
Blood in urine or dark-coloured urine.
Severe pain or fever.

If your symptoms do not improve within one to two weeks or if anything changes, please update me. I am here to help you follow up and resolve your concern.

Many young people develop temporary foamy urine after starting high-protein diets or intense workouts, and usually, staying hydrated and balancing nutrition resolves it.

I would like to ask you:

Has your protein or supplement intake recently changed compared to before?
Do you notice foamy urine all the time or only sometimes?

This helps us understand whether it is temporary or needs further investigation.

I hope that this answers your query.

Kindly follow up if you have more doubts.

Thank you.
