Taking Them On An Empty Stomach

Vitamins like iron zinc and fat soluble ones irritate the stomach lining when taken without food. Always take them with a light meal. Photo Credit: Magnific

Iron Is The Biggest Culprit

Try taking it with food or switch to a gentler form like ferrous bisglycinate which is much easier on the stomach. Photo Credit: Magnific

Too High A Dose

Your Body Is Still Adjusting

The Fillers And Additives

[{"selector":"#anim-a98c0fa2-d3d3-4da0-acdf-d4a2ef838e38","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-b10b0d87-2cfb-4987-a4e0-af25e7a451a5","keyframes":{"transform":["translate3d(0px, 127.61535%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-6e99dac0-35e5-4772-96f5-cd9782b5d42c","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-d84b9871-4aa2-4d82-9511-517f99ef33a7","keyframes":{"transform":["translate3d(0px, 425.70494%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] Some supplements contain fillers or artificial ingredients your stomach does not agree with.
