Adding the URL for the abstract was nice.
Orange Juice first is excellent for you. The potassium from OJ is terrific, also you get magnesium but less than pottasium, don’t fear the natural sugar, it’s God’s sugar. If you want to get Vitamin D get out in the Sun. Direct sunlight, unlight what you have been taught is “GOOD” for you. It was putting on sunblock that block UVB’s (which are used to create Vitamin D) and let in UVA’s (which cause skin cancer) are what caused all the skin cancer. Or put another way, the medical community really screwed and caused untold damage by giving the worse advice they could to all of America.
If you really want to supplement I suggest Carlson’s fish oil Vitamin D, they have 400 or 2000IU and I take them sometimes. But I try to get 1 hour of direct sunglight on my skin with no sunblock.
They do make sunblocks now, in case most newer ones do (with the last two years only) that block both UVB’s and UVA’s.
