In my talk I will give a short introduction to the primordial 6,7Li isotopes abundance problems and then stop specifically on the 6Li abundance called the second lithium puzzle. The  primordial 6Li abundance is determined by the rate of the reaction alpha(d,gamma)6Li. I will discuss indirect measurements of this reaction using the Coulomb breakup, calculation of the astrophysical factor for this reaction using the ANC method and the recent first successful direct measurements of this reaction by LUNA.
