Tips and tricks

• For the vaginal product, test first “Make sure you know your microbiome makeup. I recommend testing with Evvy or MicroGenDX first.” (3 upvotes)

Final take

Seed probiotics works really well for some people, especially those with IBS, SIBO, or recurring BV, but others saw no change or even got worse. If you’re dealing with chronic gut or vaginal health issues and are willing to pay for a well-formulated, science-backed option, it could be worth trying. But it’s not a magic pill, and not everyone’s gut reacts the same. Start slow, track how you feel, and don’t fall for the marketing alone.
