I have bottles that were manufactured 12/12. I bet it's safe, but will the potency of the pills be reduced due to age?

Just checked online . Yes the potency could be reduced . If they were stored some where dark and cool, only a marginal decrease in potency . NAC is a great liver cleanse and all round antioxidant. Cycle on/off ( take for 5 weeks and off for a couple ) and repeat

Do these contain gluten? Has anyone with a gluten intolerance had any problems with these?

I use this product under the direction of my pulmonary doctor for the COPD that I have Had not any problem with it

Does this include any animal products and are the capsules made from gelatin?

capsules are gelatin. contains magnesium stearate, don't know if that is animal based. website: www.swansonvitamins.com. order phone 1-800-437-4148.Hmmmm. gelatin. That would come from animals, probably.
