What supplements, vitamins, natural herbs, etc do you recommend for me

Hi, I am a 21 year old female, and I was looking to try some "alternative" medicines to boost my health. I have been taking a multi-vitamin everyday consistently for almost 2 months now and its seemed to really help my immunity and overall health. I've just been taking a regular "one a day" brand, and recently tried the energy enhanced one.

What I'm looking to aid/combat/boost:

-Fatigue and low energy. I am tired a lot, even though I regularly get 7-8 hours of sleep and excercise 3-4 times a week.

-I bruise easilly and have some spider veins on my thighs and face.

-I have difficulty concentrating and focusing when I'm trying to study. My mind wanders a lot.

-I get tension headaches regularly, and sometimes migraines.

-I have suffered from generalized anxiety disorder off and on for years.

Any recommendations would be appreciated- and please not anything to expensive- I'm a college student! Thanks. :)

FATIGUE: I would recommend Spirulina or Ultra Blue Green Algae. Ultra Blue Green Algae contains Spirulina. Spirulina may be more expensive. I get the Ultra Blue Green Algae from Walmart. It did not give me a BOOST of energy, but that is not always a good thing in itself. This just makes me feel better and I end up being able to do more.

ALFALFA - With all of the vitamins and minerals, it is bound to make you healthier. I use it throughout pregnancy for iron and energy. (Walmart has a 300 count bottle for under $4)
