Seem to cause nausea and stomach pain.Also take sublingual B-12 once a wk. and D every day. I'd also like to know if anyone has trouble with constapation and if so what are some recommendations..I have really enjoyed some of comments and am very proud of everyone. Lets keep up the good work..Thanks
