Doctors pointed out that the studies they conducted showed that biotin, or what is known as vitamin "B7", does not directly change hormone levels or vital signs in the body, but it affects the results of laboratory tests that depend on chemical reactions in the body, and false test results may appear, either high or low. This is particularly dangerous when monitoring breast, prostate, thyroid and ovarian cancer, where blood tests play a key role in assessing the effectiveness of treatment and detecting any relapses.
They also pointed out that many cancer patients take biotin on their own, based on advice from the internet, acquaintances, or even without consulting a doctor, which can lead to conflicting test results and delays in treatment. They emphasized that "harmless" dietary supplements are not always so, especially in cases of cancer.
As a safer alternative for treating hair loss, experts recommend using minoxidil, a drug with proven effectiveness and the required health certifications. Researchers emphasize the importance of always consulting a doctor before taking any supplements or medications, especially during and after cancer treatment.
