FLO Ovarian Support combines chasteberry (Vitex agnus-castus) with vitamin B6 and other nutrients to support healthy hormone balance and menstrual cycle regularity. Chasteberry has been used for centuries to address PMS symptoms and is backed by clinical research showing it can help reduce breast tenderness, mood swings, irritability, and bloating. The formula includes vitamin B6, which supports neurotransmitter production and may help with PMS-related mood changes. You’ll also get calcium, magnesium, and other minerals important for menstrual health.
Women report improvements in PMS symptoms, cycle regularity, and overall hormonal balance within 1-3 cycles of consistent use. The formula works by supporting the pituitary gland’s regulation of reproductive hormones, helping to normalize prolactin levels and support progesterone production.

MENO Menopause Gummies combine black cohosh with ashwagandha KSM-66, the most clinically studied ashwagandha extract available. Black cohosh has extensive research supporting its use for hot flash relief and has been used traditionally for menopausal symptoms for decades. Ashwagandha KSM-66 adds stress management benefits while supporting healthy cortisol levels, which can help with mood swings, anxiety, and sleep disturbances common during menopause. The formula is completely hormone-free, making it a safe option for women who cannot or prefer not to use hormone replacement therapy.
Women report noticeable reductions in hot flash frequency and intensity, improved sleep quality, and better mood stability within 4-8 weeks of consistent use. The gummy format makes taking your menopause support enjoyable rather than a chore, with a pleasant natural flavor.

No products found.
Address vaginal dryness and support intimacy with this hormone-free formula promoting natural moisture and relaxation.
MENO Vaginal Moisture capsules support natural vaginal lubrication through a blend of ashwagandha KSM-66, Ginkgo biloba, Mucuna pruriens, and GABA. This formula works by supporting healthy hormone balance, improving blood flow to pelvic tissues, and promoting relaxation that can enhance intimacy. Ginkgo biloba is particularly known for supporting circulation, which can improve tissue health and natural moisture production. Ashwagandha helps manage stress, which often contributes to decreased libido and vaginal dryness during menopause.
Women report improvements in vaginal moisture, comfort during intimacy, and overall sexual wellness within 4-6 weeks. The formula addresses dryness from multiple angles rather than just providing temporary external moisture. By supporting the body’s natural lubrication mechanisms, it offers a long-term solution.

5. O Positiv Essentials Iron + Vitamin C — Best for Energy
No products found.
Combat iron deficiency and fatigue with this enhanced formula combining iron with vitamin C for optimal absorption.
This Iron + Vitamin C formula provides 18mg of gentle iron paired with vitamin C to maximize absorption. Iron is essential for producing hemoglobin, which carries oxygen throughout your body. Low iron levels lead to fatigue, weakness, and difficulty concentrating. The addition of vitamin C increases iron absorption by up to 300%, ensuring your body actually uses the iron you’re taking. This is particularly important for menstruating women, pregnant women, and those with diagnosed iron deficiency anemia.
The formula uses a gentle form of iron that’s less likely to cause the constipation and stomach upset associated with traditional iron supplements. Women report improvements in energy levels, reduced fatigue, and better exercise tolerance within 4-8 weeks of consistent use. The 90-count bottle provides a three-month supply, making this a cost-effective option for managing iron levels. The vegan formula is third-party tested and contains no artificial colors or flavors.

No products found.
Support liver health and natural detoxification with this potent milk thistle extract standardized for silymarin.
Milk Thistle capsules deliver a concentrated extract standardized to 80% silymarin, the active compound responsible for liver-protective benefits. Silymarin acts as a powerful antioxidant and supports the liver’s natural detoxification processes. Research shows milk thistle can help protect liver cells from damage, support regeneration, and promote healthy liver enzyme levels. This is particularly valuable for women taking medications that may stress the liver or those concerned about overall liver health.
The high-potency formula provides 175mg of silymarin per serving, matching dosages used in clinical studies. Users report feeling overall better health and some notice improvements in digestive comfort and skin clarity as their liver function optimizes.

Promote calm and reduce occasional anxiousness with this pure L-theanine formula for relaxation without sedation.
L-Theanine capsules provide 200mg per serving of this amino acid naturally found in green tea. L-theanine promotes alpha brain wave activity associated with relaxed alertness, helping you feel calm without drowsiness. Research shows it can reduce stress response, support focus and concentration, and promote relaxation without affecting performance. This makes it ideal for managing daily stress, occasional anxiety, or situations where you need to stay calm but alert.
Users report feeling noticeably calmer and more focused within 30-60 minutes of taking L-theanine. The effects are gentle and natural rather than sedating, making this suitable for daytime use.

How to Choose the Right O Positiv Supplements
Start by identifying your primary health concern and life stage. O Positiv organizes their products into specific categories: URO for vaginal health, FLO for menstrual and hormone concerns, MENO for menopausal symptoms, PREGGO for pregnancy support, and Essentials for general wellness. If you’re dealing with vaginal odor or pH issues, URO Vaginal Probiotics addresses this directly. For PMS symptoms or irregular cycles, FLO Ovarian Support targets hormone balance. Menopausal women should explore the MENO line for hot flashes, night sweats, or vaginal dryness relief.
Consider whether you prefer capsules or gummies. O Positiv offers both formats for some products, each with advantages. Capsules typically provide higher potency and no added sugars, making them ideal for those watching sugar intake or wanting maximum therapeutic doses. Gummies offer convenience and pleasant taste, which can improve consistency, especially if you dislike swallowing pills. The MENO line particularly benefits from gummy availability since menopausal symptoms require long-term management where enjoyment matters.
Review the ingredient lists and clinical backing for each product. All O Positiv supplements are OBGYN-recommended and contain ingredients supported by peer-reviewed research. Look for specific strains in probiotics, standardized extracts in botanical formulas, and clinically studied forms like KSM-66 ashwagandha. The company provides transparency about ingredient sources and dosing, helping you compare to other products. Third-party testing ensures purity and potency match label claims, giving you confidence in what you’re taking.
Think about your budget and whether you need multiple products. Some women benefit from combining formulas, such as URO Vaginal Probiotics with FLO Ovarian Support for comprehensive hormonal and vaginal health. The Essentials line offers three-month supplies, providing better value for ongoing support needs. Consider starting with your primary concern first, then expanding to additional products if needed. O Positiv offers subscription options that can reduce costs for products you’ll use long-term.
