If you add a few cups of water to the orange juice, it'll be much healthier. Because there would be no orange juice left, and thus way less sugar.
OJ isn't a health food, it's junk. Eat an orange if you must, or just drink water and pop a multivitamin if you're worried about that. But don't drink OJ. Certainly not every morning. Your gut and teeth will both be better off without it.
The supplements industry is mostly a sham. You don't need any fancy chemicals to function well. Just eat enough, but not too much, of a relatively balanced diet. Supplement it with a cheap multivitamin if you're worried. That's all you need. Get some exercise, minimize stress, and you'll be way healthier than any supplement addict.
