Health supplements

You probably know by now that at SiS, we’re all about science. There is scientific evidence that health supplements work best when taken at particular times. For example, it is often recommended that you take multivitamin supplements in the morning as B Vitamins can be too stimulating for the brain before bed. Water soluble vitamins like B Vitamins and Vitamin C absorb best on an empty stomach, so you should take these around two hours prior to your meal or first thing in the morning.
