Your thyroid is the command center for your metabolism, and when it’s not functioning properly, everything—from your energy and mood to your weight and focus—can feel “off.” It can even be the reason your hair is thinning and nails are brittle.*

Unfortunately, doctors often overlook or inadequately address thyroid issues, leaving many people struggling with nagging symptoms that could be resolved with proper support.*

Doctor-formulated, science-backed Durable THYROID targets the most common underlying causes of thyroid dysfunction with powerful, clinically proven ingredients that support healthy thyroid hormone production, proper immune balance, stress resilience and overall metabolic health to help get you feeling like yourself again.*

Created by Dr. Kevin Passero, this comprehensive formula draws on his 20+ years of clinical experience helping patients overcome fatigue, sluggish metabolism, weight gain, hair loss, mood swings, brain fog and other symptoms related to suboptimal thyroid performance.*

Durable THYROID features a clinically proven extra-strength 600 mg daily dose of KSM-66® ashwagandha—the most potent, bioavailable ashwagandha extract on the market. KSM-66® is supported by 32 gold-standard clinical trials confirming its effectiveness, purity and safety.*

KSM-66® works in synergy with ForsLean® and GuguLipid®, two other powerful, patented botanicals, to promote healthy thyroid hormone activity, stimulate metabolism and support natural energy levels—without overstimulation or side effects.*

Durable THYROID also provides critical thyroid-supporting nutrients L-tyrosine, iodine, zinc and selenium to support healthy thyroid hormone production, hormone conversion, a balanced immune response, stress resilience and metabolism.*

Why Your Thyroid Might Need Extra Support—Even If You’re Already on Thyroid Medication
Unfortunately, the standard of care most doctors follow involves waiting until thyroid hormone levels fall to critically low levels before they prescribe medication. This leaves many people with low-to-normal thyroid numbers, struggling for years with frustrating symptoms caused by an underactive thyroid, thinking they have no options for relief or even being told their symptoms are all in their head.*

If this sounds like you, Durable THYROID could be instrumental in bringing your thyroid—and your entire body—back into balance. It can also help if you’re taking thyroid meds but not experiencing the symptom relief you had hoped for. You can safely take Durable THYROID alongside your thyroid medication to help improve how well your meds work—so you can finally start feeling like yourself again.*

Traditional thyroid medications often fall short because they only supply T4—the inactive form of thyroid hormone—and rely on the body to convert it into active T3. Many people lack the nutrient reserves or enzyme activity to make this critical conversion.*

Durable THYROID is designed to support this conversion process by:*

• Supporting your adrenals and reducing cortisol with KSM-66®—critical for proper thyroid function under stress
• Enhancing enzyme activity with GuguLipid®, zinc and selenium
• Replenishing l-tyrosine and iodine needed for hormone synthesis

Durable THYROID supports your body’s ability to both produce and convert thyroid hormones effectively. It addresses the cellular-level metabolism and nutrient imbalances that medications miss—helping your medication work better and helping you feel better.*

While thyroid medications attempt to “fix the numbers,” Durable THYROID helps fix how you feel—boosting energy, sharpening focus, and supporting better mood and weight balance.*

KSM-66® Ashwagandha: Nature’s Most Powerful Natural Thyroid Balancer (600 mg)
Durable THYROID is anchored by KSM-66®, a patented, organically grown, full-spectrum extract of the Ayurvedic herb ashwagandha (Withania somnifera) that has been widely studied for its effects on thyroid health, sleep, stress, mood, sexual function, athletic performance and cognition.*

Made from sustainably harvested ashwagandha roots, this standardized extract is the most clinically studied ashwagandha extract in the world, backed by 32 gold-standard clinical trials demonstrating it safety and effectiveness—and the only one proven to boost Free T3 by 41.5%.*

In clinical trials, a 600 mg daily dose of KSM-66® was shown to:*

• Normalize TSH and Free T4
• Increase Free T3 by 18.6% in 4 weeks, and by 41.5% in 8 weeks
• Reduce cortisol levels by 28% in 60 days

KSM-66®’s proven ability to reduce levels of the stress hormone cortisol and improve stress resilience may help to explain why it’s so effective at regulating thyroid function. The hypothalamic-pituitary-thyroid (HPT) axis, which controls thyroid function, is closely linked to the stress-regulating hypothalamic-pituitary-adrenal (HPA) axis. When stress goes up, thyroid output goes down. KSM-66® helps reset this balance.*

ForsLean®: Modern Science Meets Ancient Wisdom to Rev Your Metabolism (250 mg)
ForsLean® is a patented, clinically validated extract of Coleus forskohlii, a traditional Ayurvedic herb known for its metabolism-stimulating effects. This herb has received a lot of attention over the past 40 years from medical researchers, as it is the only known plant source of forskolin, a bioactive compound with many proven metabolic benefits.*

Standardized to 10% forskolin, ForsLean® works by activating adenylate cyclase, an enzyme that increases cellular levels of cAMP—a key signaler in thyroid hormone regulation and fat metabolism.*

In clinical trials, a 250 mg daily dose of ForsLean® helped subjects reduce body fat while preserving muscle mass, supporting healthy weight loss and metabolic function—especially important for individuals with thyroid-driven weight issues.*

GuguLipid® Guggul: Ayurvedic Ally for Optimal Thyroid Function (200 mg)
GuguLipid® is a patented guggul extract standardized to 2.5% guggulsterones, the active compounds known to stimulate thyroid activity. Used for centuries in Ayurvedic medicine, guggul has been shown to promote thyroid hormone synthesis and enhance the conversion of T4 to the active T3 form—essential for those struggling with low energy, mood imbalance and weight gain.*

By improving enzyme activity at the cellular level, GuguLipid® addresses a key bottleneck in thyroid hormone activation that medications alone cannot fix.*

L-Tyrosine (300 mg): Essential Thyroid Hormone Building Block #1
L-tyrosine is an amino acid and a foundational building block of thyroid hormones. The thyroid combines l-tyrosine with iodine to create both T4 and T3. Stress and poor nutrition can deplete l-tyrosine stores, impairing hormone production and leading to further symptoms.*

Durable THYROID includes 300 mg of L-tyrosine per serving to ensure your thyroid has the raw materials it needs to operate at peak performance.*

Iodine (140 mcg): Essential Thyroid Hormone Building Block #2
Iodine is an essential mineral that the thyroid gland uses to produce T4 and T3. Despite its importance, many people—especially women—don’t get enough from diet alone. Durable THYROID provides just under the recommended daily allowance (RDA), delivering effective support within a safe, daily-use range.*

Albion® Zinc (5 mg) & Albion® Selenium (125 mcg): Important Mineral Co-Factors for Thyroid Health
Zinc and selenium are trace minerals critical to thyroid hormone synthesis, conversion and antioxidant protection. Durable THYROID features Albion® chelated forms of both, which offer superior absorption and bioavailability compared to standard mineral salts.*

Zinc supports the enzymes that convert T4 into T3, while selenium protects the thyroid gland from oxidative stress and is necessary for the activation of thyroid hormones. Selenium also helps lower antibody levels and balance autoimmune inflammation associated with suboptimal thyroid function. These ultra-pure, USA-made minerals complete this robust thyroid support formula.*

Timing of Results
Like most nutritional supplements, Durable THYROID will take time and consistent use to achieve maximum effectiveness. While individual results may vary, the clinical studies show the best results often begin around 60 days, with results that keep improving over time. Dr. Passero recommends taking Durable THYROID for at least 90 days before evaluating your progress so you can make a proper assessment.

Monitoring your thyroid lab results can be a helpful way to track how Durable THYROID is supporting your thyroid health. However, remember that improved cellular balance of thyroid hormones can greatly improve how you feel—even if your lab numbers don’t change significantly. If you’re feeling better but your lab results remain the same, trust your body and continue with your regimen.
