STI Test: which supplements make sense?

The question about supplements in relation to an STI test is understandable, but the provided context contains no specific information on this topic. STI tests are diagnostic tools for detecting infections, not for nutritional guidance. Supplements cannot replace medical treatment. General immune support (e.g., zinc, vitamin C) is sometimes discussed, but there is no robust evidence from the given material that any particular supplement can influence STI test results or prevent infection. If an STI test is positive, medical treatment is mandatory. Supplements should only be taken after consulting a healthcare professional, especially if medications are involved. The evidence level is 'practice' because this reflects general medical practice rather than specific study data from the context.
