I usually take this little cocktail at night all at once because this is the only time I remember, but it is probably better to take at least 1 or 2 capsules of the calcium in the morning and a fish oil in the morning and the other capsules and vitamin at night. I'm sure as long as long as you are getting the amounts in your system though, it is better than not at all.
I also recommend an extra folic acid pill if you are trying to conceive. They are finding more neural tube defects and perhaps if we get people taking closer to 1 gm of folic acid prior to conception this rate might be lower. Folic acid is water soluble so don't worry about overdosing on this if you are taking it with a multivitamin.
There are other herbs, etc available too that I take at times including garlic, and echinacea. These are not FDA approved but I think in small amounts can have some reasonable benefits. Well, happy vitamin taking!
