Oregon’s Wild Harvest takes a whole-plant approach, using certified organic red clover flowering tops that are freshly milled and encapsulated immediately for optimum potency. The company believes in the power of whole plant medicine—the rich combination of active and inactive constituents that create balance and homeostasis in the body.
The ingredient list is remarkably simple: organic red clover blossoms and leaf (Trifolium pratense), and organic pullulan capsules (from naturally fermented tapioca starch). That’s it. No fillers, no binders, no flow agents, no additives of any kind. For purists who want nothing between them and the herb, this is the gold standard.
Manufactured in Redmond, Oregon, the company maintains full control over its supply chain and quality processes. The organic certification ensures the red clover was grown without synthetic pesticides, herbicides, or fertilizers—important for anyone concerned about environmental toxins.
The recommended dosage is one capsule three times daily with food, which means the 90-count bottle provides a 30-day supply. While this is more frequent dosing than some alternatives, it aligns with traditional herbal usage patterns and maintains steady levels throughout the day.
Note: Oregon’s Wild Harvest cautions against use if you’re sensitive to peanuts or chickpeas, as red clover is in the legume family and may trigger cross-reactions in some individuals.

The quick-release capsule technology means the gelatin shells dissolve rapidly in the digestive tract, allowing faster nutrient release compared to standard capsules. Note that these are gelatin capsules, making them unsuitable for vegans or vegetarians.

What is Red Clover and Who Should Take It?
Red clover (Trifolium pratense) is a flowering plant in the legume family that has been used in traditional medicine for centuries across Europe, North America, and Asia. The distinctive lavender-pink blossoms contain isoflavones—plant compounds that act as phytoestrogens, gently mimicking estrogen’s effects in the body without the same intensity as actual hormones.
The four primary isoflavones in red clover are formononetin, biochanin A, daidzein, and genistein. These compounds bind to estrogen receptors in the body, producing mild estrogenic effects that can help balance hormone fluctuations. Importantly, red clover’s phytoestrogens are significantly weaker than prescription estrogen medications, making them a gentler option for many women.
Women experiencing perimenopause or menopause often benefit most from red clover supplementation. As natural estrogen levels decline during this transition, symptoms like hot flashes, night sweats, mood swings, vaginal dryness, and sleep disturbances can significantly impact quality of life. The phytoestrogens in red clover can help fill the hormonal gap, potentially reducing the frequency and severity of these symptoms.
Beyond menopause support, red clover has traditionally been used for skin health, respiratory conditions, and as a general “blood purifier.” Some research suggests potential benefits for bone density maintenance and cardiovascular health, as isoflavones may support healthy cholesterol levels and arterial flexibility.
How to Choose the Right Red Clover Supplement
Key Ingredients to Look For
The most effective red clover supplements contain standardized isoflavone extracts, typically providing 40-80mg of total isoflavones per serving. This standardization ensures you’re getting a consistent dose of active compounds regardless of natural variations in the plant material. Look for products that list specific isoflavone content (measured in milligrams) rather than just raw herb weight.
The four main isoflavones—formononetin, biochanin A, daidzein, and genistein—work synergistically, so formulas containing all four offer the most comprehensive support. Some products highlight “8% isoflavones” standardization, meaning 8% of the extract weight consists of these active compounds.
For whole-herb products without standardization, dosages of 800-1,200mg of red clover blossom per serving are typical and have traditional use backing them. Concentrated extracts (like 10:1, 20:1, or 25:1 ratios) deliver equivalent benefits in smaller doses—a 25:1 extract means 200mg of extract equals 5,000mg of raw herb.
Quality certifications matter: look for Non-GMO Project Verification, USDA Organic certification, and third-party testing. GMP (Good Manufacturing Practice) compliance indicates the product was made in a facility meeting FDA quality standards.
Forms Compared
Capsules are the most common and convenient form, offering standardized dosing, easy swallowing, and longer shelf life. They’re ideal for those who want simple, once or twice-daily supplementation without measuring or taste considerations.
Tablets often contain standardized extracts with precise isoflavone measurements and may include additional binders for stability. They’re typically more compact than capsules but may take slightly longer to dissolve and absorb.
Liquid tinctures and extracts absorb faster—up to 98% absorption versus approximately 23% for capsules and tablets, according to some manufacturers. They enter the bloodstream within minutes rather than waiting for capsule dissolution in the digestive tract. However, they require more frequent dosing, careful measurement, and may have a strong herbal taste (though glycerin-based formulas tend to be naturally sweet).
Powders offer dosing flexibility and can be added to smoothies or beverages but are less common for red clover specifically. Choose based on your preferences and lifestyle—there’s no significant efficacy difference when properly dosed.
What to Avoid
Skip products with excessive fillers like maltodextrin, artificial colors, titanium dioxide, or unnecessary preservatives. If you’re vegan, check for gelatin capsules—many red clover supplements now use plant-based alternatives like hypromellose or pullulan.
Avoid products making exaggerated health claims like “cures menopause” or “eliminates all symptoms”—these claims aren’t supported by evidence and may indicate a less reputable manufacturer. Be wary of extremely cheap options that may compromise on quality, potency, or purity testing.
Check for potential allergens if you have sensitivities. Some red clover products may be processed in facilities handling common allergens like soy, wheat, or nuts. Oregon’s Wild Harvest, for example, notes that those sensitive to peanuts or chickpeas should avoid their product due to the legume family relationship.
Side Effects and Precautions
Most people tolerate red clover well when taken at recommended doses, but awareness of potential side effects helps ensure safe use. Commonly reported mild effects include headaches, nausea, muscle aches, and skin rashes or irritation. Some women experience vaginal spotting, changes in menstrual flow, or prolonged periods—effects related to red clover’s estrogenic activity. These side effects typically resolve when discontinuing use or reducing dosage.
Red clover should be avoided by pregnant or breastfeeding women due to its estrogenic activity, which could theoretically affect fetal or infant development. Women with hormone-sensitive conditions—including breast cancer, ovarian cancer, uterine cancer, uterine fibroids, or endometriosis—should consult their healthcare provider before use, as phytoestrogens may stimulate hormone-sensitive tissues.
The supplement may interact with blood thinners like warfarin, potentially increasing bleeding risk. Those taking hormone replacement therapy (HRT), birth control pills, or tamoxifen should also exercise caution, as red clover may enhance or interfere with these medications’ effects. One case report noted interaction with methotrexate (used for psoriasis and other conditions), causing severe gastrointestinal distress.
If you’re scheduled for surgery, discontinue red clover at least two weeks beforehand due to potential effects on blood clotting. Those with bleeding disorders should use red clover only under medical supervision. Always disclose all supplements to your healthcare providers, especially before starting new medications or undergoing medical procedures.
FAQs
How long does it take for red clover to work for menopause symptoms?
Most studies show benefits begin appearing after 4-6 weeks of consistent daily use, with optimal results typically seen after 8-12 weeks. Clinical trials using Promensil noted significant improvements in hot flash frequency and severity around the 8-week mark. Some women notice improvements sooner, particularly with liquid tinctures that absorb faster, but patience and consistency are key for lasting results.
What’s the recommended dosage for red clover supplements?
For standardized isoflavone extracts, 40-80mg of total isoflavones daily is the most clinically studied range. For whole-herb supplements without standardization, 800-1,200mg of red clover blossom daily is typical. Concentrated extracts may provide equivalent benefits at lower weights due to their extraction ratios. Always follow the specific product’s dosing instructions, as formulations vary significantly.
Can I take red clover with other menopause supplements?
Red clover is often combined with black cohosh, dong quai, evening primrose oil, wild yam, or vitex (chasteberry) for comprehensive menopause support. However, stacking multiple phytoestrogenic supplements may increase estrogenic effects, so start with one and add others gradually while monitoring your response. Many women find success combining red clover with non-estrogenic options like magnesium or B vitamins for sleep and mood support.
Is red clover safe for long-term use?
Studies have shown red clover to be safe for up to 2 years at doses providing up to 80mg of isoflavones daily. However, there’s limited data beyond this timeframe. Periodic breaks (such as cycling on and off every few months) and regular check-ins with your healthcare provider are advisable for any long-term supplementation, especially for hormone-related support.
Does red clover interact with any medications?
Red clover may interact with several medication types. It can enhance the effects of blood thinners like warfarin, potentially increasing bleeding risk. It may interact with hormone replacement therapy, tamoxifen, and birth control pills by competing for estrogen receptors. One documented case showed interaction with methotrexate, causing gastrointestinal distress. Always disclose all supplements to your healthcare providers before starting new medications.
Can men take red clover supplements?
While red clover is primarily marketed toward women for menopause support, some men use it for prostate health or general wellness benefits from isoflavones. However, due to its estrogenic effects, men should consult a healthcare provider before use, especially those with hormone-sensitive conditions or concerns about hormonal balance. Research on red clover for men is limited compared to women’s health applications.

Choosing the right red clover supplement depends on your priorities—whether that’s clinical evidence, organic sourcing, budget considerations, or form preference.
