Can Kre-Alkalyn or Other Supplements Cause Hair Loss?

Hello, and thanks for bringing your question to HelloPharmacist!

Since you're taking Kre-Alkalyn, let me put your mind at ease on that one first: creatine, including buffered forms like Kre-Alkalyn, has not been shown to cause hair loss. I did a quick literature search and did not find any evidence that creatine can be reliably linked to hair loss (although there have been conflicting studies that I discuss in the next section).

That said, there are a handful of supplements with a more plausible connection to hair loss, that I discuss below.

Why Creatine May Get Blamed for Hair Loss

Kre-Alkalyn is simply creatine monohydrate that has been pH-buffered, so everything we know about creatine applies to it.

The hair loss worry with creatine may partially go back to one small 2009 study in college rugby players, which found that creatine supplementation raised levels of DHT (dihydrotestosterone), the hormone involved in male pattern baldness.

Importantly, that study never measured hair loss itself, the DHT levels stayed within the normal range, and the finding has not been replicated in the years since.

More recent research looking directly at creatine and hormones has not confirmed a meaningful effect on DHT or testosterone, and no clinical study has documented creatine actually causing hair loss.

So, while we can't say the risk is absolutely zero for someone already genetically prone to pattern baldness, the evidence we have doesn't support creatine as a cause.

Supplements With a Stronger Link to Shedding

If you're troubleshooting hair loss, these are the supplement categories more commonly associated with it:

• Vitamin A in excess. Chronic high doses (well above the recommended intake), including high-dose retinol products and some 'hair, skin, and nails' stacks that layer multiple vitamin A sources, are a well-documented cause of hair loss.
• Selenium in excess. Selenium toxicity, usually from high-dose supplements, classically causes hair loss along with brittle nails.
• Vitamin E in high doses. Some evidence suggests very large doses may negatively affect hair, and megadoses offer no benefit.
• DHEA and 'testosterone booster' or prohormone products. Anything that raises androgen activity can accelerate pattern hair loss in people who are genetically susceptible. This is a real concern with some bodybuilding supplements, which have also been found to contain undeclared anabolic ingredients.
• Excess zinc taken long term, which can interfere with copper absorption and has been associated with hair changes.
• Weight loss supplements paired with crash dieting. Rapid weight loss and low protein intake are common triggers for telogen effluvium, a temporary but heavy shedding pattern.

Other Causes Worth Ruling Out

Supplements are honestly not the most common culprit when someone notices new hair loss.

Iron deficiency, thyroid problems, significant stress or illness in the prior few months, certain prescription medications, and plain genetics account for most cases.

If you're noticing real shedding or thinning, it's worth having your doctor check ferritin (iron stores), thyroid function, and vitamin D, and reviewing everything you take, prescription and supplement alike, with your pharmacist and doctor...and again, it may just be aging.

Final Words

Kre-Alkalyn is very unlikely to be behind any hair concerns, since creatine has never been shown to cause hair loss in clinical research.

The supplements to scrutinize are high-dose vitamin A, selenium, androgenic products like DHEA, and megadosed multivitamin blends. If shedding is already happening, a visit with your doctor to check for common underlying causes is the most productive next step.
