WLS Start helps prepare your body for surgery the right way. In the weeks before your bariatric surgery, your body needs to be well-nourished. Eating less or differently can leave you short on essential nutrients. WLS Start is designed to build up your vitamin and mineral levels — including nutrients that support your energy, immunity, and even help protect your hair. With just one easy-to-swallow capsule a day, you will give yourself the strong foundation you need for a successful surgery and recovery.
