Palmitoylethanolamide (PEA) in Glaucoma: A Review of Clinical Evidence Glaucoma is an eye disease marked by optic nerve damage, often linked to high intraocular pressure (IOP). Standard glaucoma treatments focus on lowering IOP, but researchers are exploring neuroprotective supplements as add-ons. One promising compound is palmitoylethanolamide (PEA), a naturally occurring fatty acid amide with an...
A nutraceutical is a product made from food sources that is used to support health or help prevent disease. The name combines ideas from nutrition and medicine to describe concentrated nutrients, herbal extracts, probiotics, fortified foods, and other bioactive compounds that go beyond ordinary eating. These products are usually sold as supplements, powders, functional foods, or concentrated extracts rather than prescription drugs. People use them to boost general wellness, manage specific symptoms, or try to reduce risks for chronic conditions like heart disease, inflammation, or age-related decline. Because many come from food, people often view them as a more natural alternative to pharmaceutical medications. However, “natural” does not automatically mean safe or effective, so care and knowledge are important before using them. The scientific support for nutraceuticals varies widely: some have strong clinical evidence while others rely mainly on tradition or small studies. Regulation often differs from that for medicines, so product quality, purity, and potency can vary between brands and regions. That variability means consumers should choose reliable manufacturers, look for third-party testing, and read labels carefully, paying attention to doses and ingredients. It’s also important to be aware of possible side effects and interactions with prescription drugs. A healthcare professional can help determine whether a particular product might be useful and ensure it won’t interfere with existing treatments. Used thoughtfully, these products can be a helpful part of a preventive or supportive health plan, but they should not replace conventional medical care for serious conditions.
