One transition. More than one system. Perimenopause doesn't show up in one place, so resW doesn't work in one place: two capsules a day supporting sleep, body comfort, mood & energy through the transition, with no synthetic hormones.*
Take 2 capsules daily, any time of day, with or without food. Perimenopause support builds gradually, so give it consistent daily use before judging how it is working for you.

Your hormones have a gut connection, & we call it the Gut-Hormone Axis.
Perimenopause is also not one symptom, so resW is not one ingredient: magnesium glycinate & L-theanine work on rest & stress, chasteberry & black cohosh are the botanicals women have leaned on through this transition for generations, & the postbiotic works from the gut side.*

Perimenopause rarely shows up as one change at a time. resW and resM work on different sides of it through the same gut-first science, so the two together cover shifts that tend to arrive together rather than one after another.*

resW is designed for women who experience those unpleasant symptoms that can occur during hormonal shift, like hot flashes, night sweats, mood changes, or sleep disturbances.*
Individual experiences may vary, but many women report feeling more balanced within 2–6 weeks.* For best results, daily consistency for as little as 90 days is recommended.*
resW is generally safe to take with most vitamins and supplements.* However, consult your healthcare provider if you're on prescription medications or managing a health condition.
resW is designed for women navigating perimenopause and menopause, while resM supports metabolism and appetite through GLP-1 pathways.* Both are doctor-formulated and work synergistically to support gut-hormone balance, many customers take them together for complete metabolic and hormonal wellness.*
resW is specifically designed for perimenopausal support, the transitional period before menopause, but is also a great supplement for any woman experiencing shifts in energy, mood, and hormones. Many women continue using it post-menopause for ongoing support*
resW is hormone-free and designed to be gentle, but we always recommend checking with your healthcare provider if you’re currently taking hormone therapy, antidepressants, or any prescription medication.
Take 2 capsules once daily, with or without food - whenever it fits best into your routine. Consistency is key for optimal results!
Yes. resW supports the Gut-Hormone connection, resM supports your metabolism, resG supports digestive health, and resB focuses on lung and immune health. Together, they work synergistically to enhance whole-body health.*
