It happens all too often — stress, poor diet, and other factors can cause our immune systems to weaken, leaving us vulnerable to colds, the flu, and other viruses. The new TravelTime bar from ResVez, Inc. makes boosting immunity as easy as having an afternoon snack. Being unveiled at the Fancy Foods show in San Francisco this month, the TravelTime bar is touted as the first gourmet nutrition bar to contain Wellmune WGP, a natural ingredient derived from a proprietary strain of baker’s yeast that is clinically proven to activate key immune cells. In the TravelTime bar it is partnered with 99 percent pure Resveratrol, the powerful antioxidant found in the skin of red grapes known to prevent free radical damage, contain anti-aging benefits, and improve heart health. TravelTime bars contain no trans fat, hydrogenated oils, high fructose corn syrup, artificial flavors, sweeteners, colors, or preservatives. They are also cholesterol-free, gluten-free, dairy-free, kosher, and vegan.

ResVez, Inc. is headed by Rancho Santa Fe-based husband and wife entrepreneurs, Malcolm and Sandy Nicholl. Malcolm, president and CEO, notes, “Whether you are a frequent traveler, parent with germy young children, stressed-out professional, or a health enthusiast, TravelTime bars make a healthy and delicious snack any time of day. They can provide everyday protection everywhere for everybody.” The company’s first product, the WineTime Bar, packs more Resveratrol than 50 glasses of red wine.
