    TLDR Researchers made a special butter with added betasitosterol that could be healthier for the heart and stayed good for three months.
    In the 2017 study, researchers successfully created betasitosterol-loaded nanostructured lipid carriers (NLCs) to enhance the nutritional profile of butter. The NLCs had a particle size of 165 nm, a polydispersity index of 0.21, a zeta potential of -13.5 mV, and an encapsulation efficiency of 96.9%. These NLCs remained stable in butter for three months, with no significant changes in particle size or polydispersity index, and the butter's quality indicators, such as acid and peroxide values, were maintained. The antioxidant capacity of betasitosterol was also preserved when encapsulated in the NLCs. The study concluded that these NLCs could be an effective way to produce functional dairy products with potential health benefits, particularly in reducing cardiovascular risks associated with butter consumption.

      Saw palmetto can help reduce DHT levels and may work in combination with other supplements like beta sitosterol and pygume, but it's less effective than finasteride. Additional treatments like pumpkin seed extract, zinc, biotin, essential oils, scalp massages, and micro-needling can support hair health, but should not replace existing treatments like finasteride.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.
