These are the things i am taking, korean red ginseng, multivitamen, fish oil, vitamen c, vegetable protein and loratadine tablets (for allergies). are these alright together?

Yes: There are no adverse interactions between these things. Make sure you take a high-quality multivit. At least 1/3 of adults can't convert Folic Acid to the active form, l-5-mthf ; anxiety/high BP makes it likely you need a multivit that has the l-5-mthf form. Also most adults need 5-8000 iu of d3 in fall ; winter months to achieve optimal levels- see http://bit.Ly/1ekkvkv ; http://bit.Ly/1dc7vna.
