I only open the bottle to get a pill, then i close it. but i noticed that theyve changed color since i cracked the bottle open the first time. does this mean they are less vitaminy? should i buy them in smaller quantities? I bought the big 250 pill bottle from costco of one-a-day. should I buy some coated ones instead?
sorry if this has been brought up before.
