A period claim with a pharmacology file. Semaine grew from one pain free cycle into a catalog for cycle, gut, bladder and menopause, all described as plant based, finished formula studied, and batch tested by outside labs. Half Life asked what form, what amount, what absorption number, and what the studies can and cannot carry.

The category runs on soft language. Semaine wants to sit inside it while sounding like a lot record, with named extracts, stated amounts, outside testing and use windows printed on the panel. That tension is why this interview stays close to dose and paperwork rather than story.

Lauren Lee is listed as chief executive and cofounder. Matt Crane is listed as cofounder and chief science officer. The third person in the origin account is Lar, who is Matt’s wife, and whose long history with severe cyclic pain and endometriosis started the work. Cath and Lar are twin sisters. Both carry the same DNA and both carry an endometriosis diagnosis. The brand reports that neither first received a clear path forward.

What Semaine sells today follows that origin. The range includes plant based products aimed at menstrual complaints, PMS, hormonal balance, digestive health and bladder support. The company reports that its completed blends are studied in clinical work by an outside independent lab, and that each supplement receives outside testing for quality and purity. It cites a medical advisory board across gynecology, urology and other fields. The point worth checking is the paper behind the promise. Semaine invites review through records, not slogans.

Your PMS Relief Capsule at 32.99 dollars says to start it with the first PMS symptoms and stop when your period ends, so what in the dose and duration made episodic use more defensible than daily use.

I am Lauren, and I will open here because Matt and I saw it from separate sides. Lar is in our family. We saw her told that intense pain was ordinary, then sent home lacking a plan. Years with brushed aside complaints and partial replies alter how you read any claim. You cease to trust a front panel. You flip the bottle over.

When Matt drew on his training to assemble a plant based blend and Lar then recorded her first pain free period, we did not assume we held a reply for all. We felt we held a duty to examine it correctly. That explains our line about building the remedies we could not locate, rooted in the view that every woman merits them. For me, a panel must display its support. It should list what sits in the capsule, the quantity, the chemical form, and what examination stands behind it. Our buyer scans the Supplement Facts panel plus the other ingredients line. She shops for herself and commonly for a home. She retains a product across years when it earns a place. Earning that place is our task.

Your about page says Lar spent years with dismissed symptoms and incomplete answers before a plant based formula gave her first pain free period, so what did those years teach you about what a label has to prove.

I am Matt, and that point counts for me as a researcher. Identical DNA, identical diagnosis, distinct course. It drove home that female physiology is not several hormones, it is an integrated system. Hormones move by day, by week, by month and over a lifetime. That rhythm even lives in our name. Semaine translates from French as week.

We did not aim to craft a single cramp capsule and finish. What started with menstrual pain turned into a charge to bring balance back at the source. That sentence steers recipe work. We view cycle, gut, bladder and mood as connected. We act at the source of what you sense, not only at outward signs. Source depth, not surface depth. Phrasing that is simple. Demonstrating it is less simple. For us it calls for research on the completed blend, not just one part alone, plus candor on use and on discontinuation. Born from love. Backed by biology. That remains our internal bar.

Your brand also says every supplement is third party tested for quality and purity, so can you walk us from the field to that certificate of analysis in the order the material moves.

I am Matt again. The sequence runs field or fermentation vessel, then drying plus extraction, then powder or oil, then encapsulation, then lot based testing. A cultivator gathers the botanical. That harvest lot is dried to manage moisture. Next comes extraction, where a solvent or alternate process draws the desired fraction into a powder or oil carrying a declared extract ratio or standardized marker, set out in our specification sheet and then on the panel where rules require.

That bulk powder comes with companion records. Next we blend to fill weight, encapsulate, and quarantine the completed lot. An outside lab examines that lot for identity, potency and contaminants, covering heavy metals and microbes where relevant, and releases a certificate of analysis. The certificate attaches to a lot and batch code, not to the company broadly. When we report that each supplement passes outside testing for quality and purity, we refer to that completed lot control. When a shopper seeks the precise origin of a botanical, the lot file should tie cultivator, harvest, extract and completed capsule. That linkage is the file we are working to display.

Your site says you run clinical studies on your formulas with an independent third party lab, and have done so since day one, so what does that testing measure and what does it leave unmeasured.

I am Matt. We conduct clinical work on our blends with an outside, independent lab. Tangible data, not only our assertion. Conducting clinical work on our blends from the first day was a decision taken prior to size. It adds cost. It adds duration. We viewed it as the sole route to request confidence.

To be precise, we examine the finished mixture as marketed, not just components. The lab stands apart, so method plus data capture rest beyond our staff. That structure allows us to report what enrollees described in trial settings. What it fails to do is establish what a capsule may do for any single reader. Any trial carries bounds around enrollment, length and cohort. We convey outcomes as the brand conveys them, while the panel carries contents plus directions. We do not ask research to bear beyond its capacity. We retain the medical advisory board across gynecology, urology and further areas so teaching remains inside what was truly gauged.

Your Hormone Balance at 36.99 dollars combines three botanicals plus essential vitamins and minerals for daily mood energy and cravings support, so how do you decide which plants earn a place when the front label cannot name every field.

I am Lauren. We created this because we require it. The PMS Relief Capsule links to our beginning. It calms menstrual complaints such as mood shifts, bloating, and cramps, using the brand’s stated wording. Those phrases sit on the panel and the product page. They note what the blend is meant to support, not what it must do for you.

Cyclical use followed Lar’s rhythm. Complaints climbed, then receded. Month long daily intake did not fit that cycle for her. Thus directions say begin at first PMS signs and halt when the period ends. That also renders the supply math plain for the purchaser. A single pack holds the stated count for that period. The two pack at 64.98 dollars and three pack at 89.97 dollars repeat that same interval. We maintained a plant based recipe because that was what we could track, obtain steadily, and assess as a completed blend. When ongoing support for mood, energy and cravings is wanted, we direct toward a daily blend instead.

A study has limits in size and time and population.

Lauren Lee and Matt Crane

You name twin sisters Cath and Lar who share DNA and an endometriosis diagnosis but did not share a clear answer, so how did that fact shape the choice to build Semaine for more than one body.

I am Matt. A front panel offers scant space. The Supplement Facts panel offers greater space. Our task is precision on the back panel. For Hormone Balance, the panel records three botanicals plus essential vitamins and minerals. Every item carries a form, a part utilized, a per serving quantity, plus an extract ratio or standardization when relevant. That detail permits a diligent shopper to set one bottle beside another.

Choice begins with historical use plus public study, then turns to sourcing. Whether a cultivator can supply an identical marker crop after crop. Whether the extractor can preserve that marker absent a switch in solvents that we would decline. Whether the completed lot can satisfy our standard for quality and purity. Absent that, the plant fails to win a slot, no matter how appealing it reads. The other ingredients line counts equally. Shell, fill aids, color. We compress it where possible, and we disclose what stays. Clean and pure function as claims. We attempt to place files after them.

Your team page notes that many of the team are women and half live with chronic health conditions, with a medical advisory board in gynecology urology and beyond, so how does that shape testing and plain language.

I am Matt. I will remain near what the panel displays. The item hinges on Anthocran Phytosome cranberry, a cranberry extract complexed in phytosome format meant to aid uptake. The page carries 3x better absorbed. That multiple points to the raw material vendor’s reported data for that format, not to our completed capsule in isolation. We repeat it exactly as the brand repeats it.

What we can track is extract identity, per serving amount, daily use toward urinary support, plus completed lot examination for quality and purity. What we say on role is tight. Most urinary products aim at the bacteria alone. We target the biofilm. Steady daily effort, at the source. That wording signals intended site of action, not assured result. What stays unclear, candidly, is the complete field chart for each harvest. We can identify extract plus form plus lot. Comprehensive cultivator level mapping for each botanical across each season remains the next record to release, and we recognize it.

Your Urinary Tract Cleanse and Protect at 30.99 dollars centers on Anthocran Phytosome cranberry described as 3x better absorbed and says you address the biofilm while hibiscus supports immunity in your positioning, so what can you trace and what is still opaque.

I am Lauren. Women’s health is not several hormones, it is an entire system. That conviction made broadening logical. Bladder troubles, digestive troubles, hormonal transitions and menopause complaints kept surfacing in shared homes. Women informed us their complaints were ordinary. We decline that reply. We decline shallow masking absent source work. We decline to market science absent outside clinical work plus quality assays.

We preserve the link by preserving identical records. Every fresh blend receives the same chain. Specification, completed blend research via an outside lab where declared, lot assays, plain directions. The Peri and Meno Essentials at 36.99 dollars is said to be clinically studied for 14 menopause measures, from hot flashes and mood swings to hair thickness, in brand wording. The Pre and Probiotic for Women at 32.99 dollars is said to include ginger extract for digestion, nausea, bloating and intestinal discomfort. We do not blend their narratives. Each panel rests upon its own lot file.

You expanded from periods into bladder gut and perimenopause and menopause support, including a 40 plus line and a Microbiome Protocol, so how do you keep a whole system view without losing the thread back to the capsule.

I am Lauren. It guides what we refuse to state. When half the staff navigates chronic illness, hype turns personal. We understand reading a panel at a pharmacy shelf during pain. Thus we script directions as plain stages. When to begin. When to cease. Daily or cyclical. With food or as instructed. We claim plant based where accurate. We claim outside testing where accurate.

The board maintains precision. Gynecology, urology and further fields means a bladder assertion receives urology review, a cycle assertion receives gynecology review. They assess method wording plus teaching so we outline what was examined absent morphing it into guidance for a reader’s condition. We Made This Because We Need It is not a tagline for us. It signals that tester plus buyer are commonly one staffer in our office. That lifts the bar for documentation, not just prose.

Semaine is French for week, which you link to hormones changing daily weekly monthly and through life, so what would it take to show the full chain for one bottle, from grower to capsule, without gaps.

I am Matt and Lauren jointly here, since it spans operations plus pledge. It would require listing the cultivator plus harvest lot, documenting the drying technique and extraction technique with ratio or standardized marker, identifying the encapsulation plant plus fill weight, and releasing the completed lot certificate of analysis showing heavy metals plus microbe outcomes. Then tying that dossier to the lot code stamped on the bottle.

We hold segments of that chain now through specifications plus outside assays. The seasonal field chart forms the segment still under assembly across a broader span, as crops rotate and vendors turn over. What they lacked in common was a clear answer, thus they moved to construct one, for their own home and for women repeatedly told their severe cyclic complaints were ordinary. That line still steers us. The reply must be traceable. Where a stage cannot be shown, we admit it, and we outline what display would require. That is how a week to week account earns shelf space across years.

Closing note from the desk

What remains at the desk after this exchange is sequence. The founders open with a home account, then pivot fast to lot codes, extract formats and outside labs. Wording stays narrow where precision matters, on the panel and in use instructions, and widens only to state purpose.

Semaine aimed to bring balance back at the source and help women feel more like themselves through studied blends. In plain documentation terms, that equals plant based mixtures, completed blend research via an outside lab as reported, lot testing for quality and purity as reported, and panels that inform a careful shopper on start and stop timing.
