Bryan Johnson Posts 100/100 Kate Tolo Report, Top 1% Claim
bryan johnson put Kate Tolo’s vaginal microbiome report on X and said it scored 100/100, placing it in the top 1% of all vaginas. The post turned a private test into a very public discussion because Johnson is 48 and known for spending heavily on anti-aging efforts.
Johnson’s 100/100 post
Johnson wrote, "Just gave Kate oral sex. Goodnight everyone." He later followed with, "This is her vaginal microbiome report. 100/100 score. Top 1% of all vaginas."
He also said Tolo’s sample was 98.7% L. crispatus-dominant and that the lab found nothing bad to report. In the same thread, he added that only about 25-30% of reproductive age women globally are L. crispatus-dominant.
What the lab score implies
Johnson framed the result as more than a one-off test, saying a vaginal microbiome is downstream of sleep, glucose control, stress, gut health, sexual health, immune function, diet, and what a person puts in it. He also said the sample was dominated by the single most protective bacterial species a vagina can host.
That makes the post less about novelty than about the way Johnson keeps tying personal health data to public performance. He has featured in the Netflix documentary Don't Die and has spent a fortune trying to reverse the ageing process, so even an intimate lab result lands as part of his broader health brand.
Tolo’s oral sex warning
Tolo replied that oral sex carries genuine risks. She wrote, "I know this seems unhinged, but oral sex isn’t talked about enough."
She said "HSV-1 (oral herpes) can be transmitted to the genitals and vice versa," added that "HPV passed through oral sex is now the leading cause of oropharyngeal cancers in the US (surpassing tobacco)," and warned that "The bacteria in saliva can also disrupt the vaginal microbiome, and studies have linked receptive oral sex to higher rates of bacterial vaginosis."
She closed by calling it "a public health gap," said she is grateful she has a partner who takes her health, his health, and their collective health seriously, and ended with "Be safe lovely humans." The immediate takeaway is blunt: Johnson’s post was not just oversharing, but a bid to frame sexual health as measurable, searchable, and fair game for public discussion.
