Hello. I was wondering if it would be ok to take Lutein supplement in combination with beta-carotene to treat the slight blurriness in my right eye. Will this be causing any interactions in the long run? I think I’ve read somewhere that 25000 IU is the maximum dosage an adult can take as a dietary supplement on a daily basis. I intend to take about half this value (10 000 IU from a beta carotene supplement and 2500 IU or so from spirulina or other whole food supplements)
What about the side effects (joints and bones pains, diarrhea, dizziness) and how accurate is the lung cancer thing? I am a very light smoker (I sometimes smoke about 2 cigarettes a day). Are there any other side-effects I should be aware of. Besides, should I supplement on zinc when taking high daily doses of copper (up to 10 mg)? Thanks!
