When taking β-carotene, can you take 7 capsules once a week instead of one a day?
I am not very clear about the difference between vitamin A and beta-carotene. But I gather that vitamin A is stored in the liver: enough for at least a year. Does this mean that when taking a beta-carotene supplement, you can have, say, 7 capsules once a week, instead of one a day?
I ask this because I read that, if eaten simultaneously, beta-carotene reduces lutein bioavailability, and I have to take lutein with most meals (for my eyes and skin).
