Geschenkgutschein: what does this mean exactly?

A 'Geschenkgutschein' (gift voucher) at MyBodyX is a prepaid certificate that can be gifted. The recipient redeems it for one of the offered DNA or microbiome tests. This is purely a marketing and sales tool – the scientific evidence for the tests themselves varies by product (see context: some markers like FTO have only weak effects, microbiome tests are not yet standardized). The voucher does not affect the validity of the test results.
