New Costco Find - Liposomal Vitamin C #SRPartner With cold weather coming soon, I was so excited when I saw this at Costco. SportsResearch supplements have my vote of confidence. It’s clinically-researched Liposomal Vitamin C with 500 mg of Vitamin C Per Serving - plus it’s a big bottle that lasts! You won’t want to miss out, get it at Costco today! #SunkissedKitchen #CostcoVitaminC #supplements #costco #healthymom #healthylife
