I was prescribed Nifediprine er 30mg for Raynaud s syndrome. I also take multiviatamins w/minerals, fish oil, curcumin, glucosamine & chondroitin, aplha lipoic acid, COQ10, garlic, and saw palmetto. Is there any significant problem with mixing these. I don t take Nifediprine at the same time as the other supplements. I separate it from the supplements by taking the Nifediprine about 9 hours later.
