    > fatty acids. In addition, vitamin E (as alpha-tocopherol
    > along with other tocopherols) should be taken with any fatty

      si.. ritengo prorio che il cla se preso in certi modi sia proprio una buona cosa. già sperimentato anni fa... è che poi va un po' a periodi. certo è che non ne prendevo mai più di 3 g... ora ne ho preso un kilo e mezzo e vediamo cosa succede a 5 gr giorno

      love
