I do not suggest stopping any Dr. prescribed supplements.
Since chia and goji do not contain DHA omega-3, you can continue taking that one. Calcium will depend on your needs, however to give you reference... 1 ounce (about 2 Tbsp) of chia seeds contains only 17% of your daily calcium needs.
Thank-you. One more question please. Each time I try to make a nutri-blast using Collard Greens or Kale it tears my stomach up. Any suggestions?
