How long does it take to reduce ast and alt levels? Mine are high. I started taking iron supplements recently and have been doing much exercise. It appears that these things may result in higher levels. Also, we are craft beer afficianados. I tend to binge on this, maybe 2, 3, or 4 on a weekend evening and then none for a week or two. Do I really need to quit doing this. My husband of 35 years really enjoys it and we have super active, generally healthy lifestyle? It is almost a quality of life thing.
