Nature's Way Horsetail Review

Nature's Way Horsetail Grass is presented as a daily traditional beauty supplement. The page describes horsetail, also known as bottle brush, as a perennial that has been used as a remedy dating back to ancient Greek and Roman times, and says it is named for its feathery leaves, which look like a horse's tail. The product is positioned to look to nature for beauty benefits and to traditionally support healthy hair and nails. The label states that each serving contains 440 mg of horsetail (stem, leaf) for traditional nail and hair support. The listed serving size is one capsule, and adults are directed to take 1 capsule three times daily while increasing fluid intake during use. The other ingredients are listed as a plant-derived capsule made of hypromellose. The product is described as vegan, dairy-free, soy-free, and vegetarian, with no artificial colors or flavors, and the page states it does not contain salt, corn, soy, dairy, gelatin, artificial colors, flavors, or preservatives. Safety information advises that pregnant or nursing people, those with kidney dysfunction, or anyone taking medications should consult a healthcare professional before use. The bottle is described as having an inner seal, and users are told not to use it if the seal is broken or missing, to keep it tightly closed, and to store it at room temperature away from excessive heat and direct sunlight. The page explains that Nature's Way applies testing to every ingredient, covering identity, purity, potency, composition, and contaminants such as bacteria, heavy metals, and residual chemicals. The brand notes that for over fifty years it has looked to the natural world for inspiration. The page includes a transparency notice stating that its statements have not been evaluated by the Food and Drug Administration and that the product is not intended to diagnose, treat, cure, or prevent any disease. The product is backordered at the time of capture and will ship when back in stock. A one-time purchase price of $11.99 is shown, with a subscribe and save option that lists a discounted price of $10.19, and a buy three get one free promotion appears on the page. Shipping is free on orders of $49 or more, and the store offers a 45-day satisfaction guarantee.
