When you have low sex drive it can be tempting to try and find a quick fix such as a vitamin or medication to increase your desire. While a vitamin deficiency might be part of why you have low desire, it likely isn't the whole cause. Because the thing is, desire is much more complicated than simply a biological urge - it's affected by psychological, relationship, and even cultural factors. This means sex drive isn't just a matter of your physiology, and looking to increase it through a vitamin likely won't be sufficient. For decades the medical industry has worked on developing various medications for low sex drive in females such as Flibanserin and Bremelanotide. These medications cause a lot of side effects such as headaches and nausea and are quite ineffective in increasing desire, too. For this reason alone it's important to consider other ways of getting your sex drive back such as sex therapy, alongside getting some blood work done. This will shine a light on all possible factors contributing to your low libido and ways of increasing it.
