Brief summary: A randomized, double-blind, placebo-controlled, direct-to-consumer study assessing the impact of health and wellness products on sexual health and related health outcomes.

Detailed description: This is a randomized, double-blind, placebo-controlled study conducted with adult participants, residing in the United States. Eligible participants will (1) endorse a desire for improved libido (sex drive), sexual satisfaction and/or function, (2) have the opportunity for meaningful improvement (at least 30%) in their primary health outcome, and (3) express acceptance in taking a product and not knowing its formulation until the end of the study. Participants that report a known cardiac dysfunction, liver or kidney disease may be excluded. Participants that report a known contraindication or with well-established, significant safety concerns due to illness will be excluded. Heavy drinkers and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded. Participants that report taking medications with a known contraindication or with well-established, significant safety concerns will be excluded. Self-reported data are collected electronically from eligible participants for 7 weeks. Participant reports of health indicators will be collected at baseline, throughout the active period of study product use, and in a final survey. All study assessments will be electronic; there are no in-person visits or assessments for this real-world evidence study.

Eligibility criteria: Inclusion Criteria:

* Adults, at least 21 years of age at the time of electronic consent, inclusive of all ethnicities, races, and gender identities - Assigned sex at birth is female
* Resides in the United States
* Endorses improved libido (sex drive), sexual satisfaction and/or function as a primary desire
* Has the opportunity for at least 30% improvement in their primary health outcome
* Expresses a willingness to take a study product and not know the product identity (active or placebo) until the end of the study

Exclusion Criteria:

* Report being pregnant, trying to become pregnant, or breastfeeding
* Unable to provide a valid US shipping address and mobile phone number

* Reports being a heavy drinker (defined as drinking 3 or more alcoholic beverages per day)
* Unable to read and understand English
* Reports a current and/or recent (up to 3 months ago) major illness and/or surgery that poses a known, significant safety risk.
* Reports a diagnosis of cardiac dysfunction, liver or kidney disease that presents a known contraindication and/or a significant safety risk with any of the study product ingredients.

  o NYHA Class III or IV congestive heart failure, atrial fibrillation, uncontrolled arrhythmias, cirrhosis, end-stage liver disease, stage 3b or 4 chronic kidney disease, or kidney failure
* Reports taking medications that have a well-established moderate or severe interaction, posing a substantial safety risk with any of the study product ingredients.
