Brief summary: The goal of this study is to investigate the effect of pollen extracts on menopausal symptoms in healthy women The main question it aims to answer is:

What is the difference in change in severity of menopausal symptoms as assessed by the total Menopause Rating Scale (MRS) score from baseline at Week 36 between Graminex Water Soluble Pollen Extract (WSPE), Lipid Soluble Pollen Extract (LSPE), and Placebo?

Participants will be asked to complete the MRS assessment tool to rate their menopausal symptoms while receiving either WSPE, LSPE, or Placebo.


Eligibility criteria: Inclusion Criteria:

1. Females between 45-60 years of age, inclusive
2. BMI 18.5 kg/m2 - 34.9 kg/m2 inclusive
3. Self-reported menopausal women who have not had a menstrual period for \>12 months prior to screening and are experiencing at least moderate menopausal symptoms as assessed by the total MRS score of ≥9 at screening
4. Presence of menopausal symptoms for at least six months prior to screening including, vasomotor symptoms (hot flushes, sweating) AND at least two of the following symptoms: sleep disturbance, joint pain, mood changes, fatigue and lack of energy, vaginal dryness, urinary changes, and changes in sexual function
5. Agrees to maintain current lifestyle as much as possible throughout the study, including diet, exercise, medications, dietary supplements, and sleep
6. Able and willing to complete all study assessments
7. Provided voluntary, written, informed consent to participate in the study
8. Healthy as determined by medical history with no unstable, diagnosed medical conditions as assessed by the Qualified Investigator (QI)

Exclusion Criteria:

1. Females who have had unilateral oophorectomy or hysterectomy or uterine ablation

5. Current untreated urogenital diagnosis as assessed by the QI
6. Unstable metabolic disease or chronic diseases as assessed by the QI
7. Current or history of any significant diseases of the gastrointestinal tract as assessed by the QI
8. Unstable hypertension. Treatment on a stable dose of medication for at least 3 months will be considered by the QI
9. Current unstable Type I or Type II diabetes
10. Significant cardiovascular event in the past six months. Participants with no significant cardiovascular event on stable medication may be included after assessment by the QI on a case-by-case basis

12. Self-reported confirmation of current or pre-existing thyroid condition. Treatment on a stable dose of medication for at least three months will be considered by the QI
13. Major surgery in the past three months or individuals who have planned surgery during the course of the study. Participants with minor surgery will be considered on a case-by-case basis by the QI
14. Cancer, except skin basal cell carcinoma completely excised with no chemotherapy or radiation with a follow up that is negative. Volunteers with cancer in full remission for more than five years
15. after diagnosis are acceptable
16. Individuals with unstable autoimmune disease or are immune compromised as assessed by the QI

24. Any other condition or lifestyle factor, that, in the opinion of the QI, may adversely affect the participant's ability to complete the study or its measures or pose significant risk to the participant
