ZonalFit recommends Thorne, the only supplement brand that collaborates with Mayo Clinic on wellness research, with evidence-based options tailored to your hormonal lifecycle. We are a Thorne affiliate.
Formulated specifically to support hormonal balance and comfort during menopause and perimenopause.
Thorne's Meta-Balance combines ashwagandha, black cohosh, and other botanicals traditionally used to support women through hormonal transitions. Many women report improvements in hot flash frequency, sleep quality, and overall comfort. Designed for daily use during perimenopause and beyond.
Supports sleep quality, muscle recovery, and mood regulation during hormonal transition.
Bisglycinate is one of the most bioavailable forms of magnesium, meaning your body absorbs more of it with less digestive discomfort. Magnesium plays a role in over 300 enzymatic reactions, including those involved in sleep regulation and muscle function. Particularly relevant during perimenopause when sleep disruption is common.
Supports healthy inflammatory response and joint comfort during perimenopause.
Thorne's phytosome form delivers significantly better absorption than standard curcumin supplements. Joint discomfort and stiffness are common during perimenopause due to shifting estrogen levels. Curcumin supports a healthy inflammatory response without the side effects associated with long-term NSAID use.
Supports bone density, a primary concern for women in perimenopause and beyond.
Vitamin D is essential for calcium absorption and bone health, both of which become critical priorities after estrogen levels decline. Many women are deficient without knowing it, especially those who train indoors or live in northern climates. The 5,000 IU dose is appropriate for women with confirmed low levels (ask your provider to test).
Formulated to support hormonal and ovarian health in women with PCOS.
Thorne's Ovarian Care contains a combination of myo-inositol and D-chiro-inositol in a research-supported 40:1 ratio. Inositol has been studied for its role in supporting insulin signaling and ovarian function in women with PCOS. This is one of the most evidence-backed supplements for PCOS specifically.
Supports healthy blood sugar and insulin sensitivity, a key factor in PCOS management.
Berberine is a plant compound that has been studied for its effects on glucose metabolism and insulin sensitivity. For women with PCOS, insulin resistance is often a root driver of symptoms including irregular cycles and difficulty managing weight. Berberine is best taken with meals for optimal absorption.
Supports antioxidant status and hormonal balance in women with PCOS.
N-Acetylcysteine is a precursor to glutathione, your body's primary antioxidant. Research has explored NAC's role in supporting hormonal balance and ovulatory function in women with PCOS. It also supports liver detoxification pathways, which play a role in hormone metabolism.
Bioavailable folate for women with MTHFR variants, which are more common in women with PCOS.
5-MTHF is the active, methylated form of folate that bypasses the MTHFR enzyme entirely. Up to 40% of women carry MTHFR variants that reduce their ability to convert folic acid into usable folate. This is especially relevant for women with PCOS who may be planning pregnancy.
Continued micronutrient support during postpartum recovery and breastfeeding.
Nutrient demands don't end at delivery. Breastfeeding mothers have elevated needs for vitamins A, C, D, and several B vitamins. Thorne's prenatal is formulated with bioavailable forms including methylated folate and chelated minerals for better absorption.
Omega-3 support critical for postpartum recovery and infant development during breastfeeding.
DHA is an omega-3 fatty acid critical for infant brain and eye development during breastfeeding. Postpartum depletion of DHA is common, as the body prioritizes the infant's needs over the mother's stores. Supplementation supports both maternal recovery and infant development.
Supports iron replenishment during postpartum recovery.
Blood loss during delivery can significantly deplete iron stores. Symptoms of low iron include fatigue, brain fog, and reduced exercise tolerance, all of which overlap with normal postpartum exhaustion. Thorne's iron complex includes cofactors like vitamin C to support absorption.
Higher-dose bioavailable folate to support recovery and breastfeeding demands.
The higher 5mg dose provides additional folate support during the increased demands of postpartum recovery and breastfeeding. Folate is essential for tissue repair, red blood cell production, and energy metabolism. This dose is appropriate for women with known MTHFR variants or those directed by their provider.
Supports lean muscle preservation during significant body composition changes.
Research shows that up to 40% of weight lost on GLP-1 medications can come from lean muscle mass rather than fat. Adequate protein intake (1.2 to 1.6g per kg of body weight) is one of the most effective ways to preserve muscle during weight loss. Whey isolate is fast-absorbing and well-tolerated by most.
Replenishes micronutrients that may be reduced with lower food intake.
Reduced food intake on GLP-1 medications means fewer opportunities to get essential vitamins and minerals from diet alone. Common deficiencies include B12, iron, zinc, and magnesium. A comprehensive multivitamin helps fill the gaps without requiring multiple separate supplements.
Supports recovery and sleep quality during body composition changes.
Magnesium is often under-consumed even without appetite suppression, and GLP-1 medications can compound the deficit. The bisglycinate form is gentle on the stomach, which matters when nausea is already a common medication side effect. Supports sleep, recovery, and muscle function.
Supports lean muscle and connective tissue during significant weight change.
Rapid weight loss can affect skin elasticity and connective tissue integrity. Collagen peptides provide the amino acids (glycine, proline, hydroxyproline) that support skin, joint, and tendon health. Best taken consistently over 8 to 12 weeks to see benefits.
Supports cardiovascular and inflammatory health during active weight loss.
Omega-3 fatty acids support cardiovascular health, which is relevant during periods of significant body composition change. CoQ10 is a coenzyme involved in cellular energy production and antioxidant defense. This combination supports both heart health and exercise recovery.
Sustained anti-inflammatory support for women managing chronic inflammation.
The sustained-release formulation provides consistent curcumin levels throughout the day rather than a single peak and decline. Chronic inflammatory conditions benefit from steady-state support. Thorne's phytosome technology significantly improves bioavailability compared to standard curcumin.
Supports comfort and recovery during high-symptom periods.
Magnesium supports muscle relaxation and may help with the pelvic cramping and discomfort associated with endometriosis flares. The bisglycinate form is the least likely to cause digestive issues, which is important for women already managing GI symptoms. Also supports sleep quality during high-pain periods.
Supports antioxidant status and healthy inflammatory response.
N-Acetylcysteine supports glutathione production, your body's most important endogenous antioxidant. Oxidative stress has been studied as a factor in endometriosis progression. NAC also supports liver function, which plays a role in estrogen metabolism and clearance.
Supports healthy inflammatory response for women managing endometriosis.
Omega-3 fatty acids (EPA and DHA) have been studied for their role in supporting a balanced inflammatory response. For women with endometriosis, this is particularly relevant during flare periods. The added CoQ10 supports mitochondrial energy production during times of fatigue.
Foundational micronutrient support for active women managing a chronic condition.
Managing a chronic condition places additional demands on your body's nutritional reserves. A comprehensive daily multivitamin ensures baseline micronutrient needs are covered, especially when pain or fatigue affects appetite and food quality. Formulated for active women with bioavailable mineral forms.
Core multivitamin formulated for active women.
Thorne's two-per-day multivitamin provides foundational coverage of essential vitamins and chelated minerals. Formulated without unnecessary fillers or common allergens. A solid baseline for active women before layering in condition-specific supplements.
Foundational vitamin D support for hormonal and immune health.
Vitamin D plays a role in immune regulation, bone health, and hormonal signaling. Deficiency is common, with estimates suggesting over 40% of U.S. adults have suboptimal levels. The liquid form allows flexible dosing based on your tested levels.
Supports hormonal balance and immune function in active women.
Zinc is involved in over 100 enzymatic processes including hormone production, immune function, and protein synthesis. The picolinate form is one of the most bioavailable options available. Active women lose zinc through sweat, making supplementation especially relevant for those who train regularly.
Electrolyte and hydration support for training performance.
Catalyte provides a balanced electrolyte profile (sodium, potassium, magnesium) along with B vitamins to support hydration and energy during training. Unlike many sports drinks, it's free of artificial sweeteners and excessive sugar. Particularly useful for women who train in heat or sweat heavily.
Connective tissue support for active training.
Collagen Fit is specifically formulated for active individuals, combining collagen peptides with other connective tissue nutrients. Tendons, ligaments, and cartilage rely on collagen for structural integrity. Regular supplementation supports joint health and may reduce exercise-related joint discomfort over time.
