Want to improve your health? Don't buy from Swanson. I used this company's products for years. Never saw benefit. Then they double charged me for part of my order and after about 50 attempts to correct it, they didn't. It's the same inept no help every single time you try--even with a supervisor. Aside from not correcting overcharging a customer, they also do not care about customer retention. Swanson literally offers the WORST service I have seen in my life.
