NAC has a number of potential health benefits. It is a source of the antioxidant enzyme glutathione, which is important for protecting cells from oxidative stress and supporting immune function. It also may have anti-inflammatory effects and studies show it may support healthy brain function.
It is generally considered safe to take NAC supplements in recommended doses.
Bictegravir, Emtricitabine, Tenofovir Alafenamide Overview
-
The combination of bictegravir, emtricitabine, and tenofovir AF is used to treat human immunodeficiency virus (HIV) infection in certain adults and children weighing at least 55 pounds (25 kg) who have not received antiretroviral treatment in the past or who have been stable on other antiretroviral treatment(s). Bictegravir is in a class of medications called integrase strand transfer inhibitors (INSTIs). Emtricitabine and tenofovir AF are in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). The combination of bictegravir, emtricitabine, and tenofovir AF works by decreasing the amount of HIV in the body. Although bictegravir, emtricitabine, and tenofovir AF will not cure HIV, these medications may decrease your chance of developing acquired immunodeficiency syndrome (AIDS) and HIV-related illnesses such as serious infections or cancer. Taking these medications along with practicing safer sex and making other lifestyle changes may decrease the risk of getting or transmitting the HIV virus to other people.
