Many patients feel more energetic within 24 to 72 hours after receiving a B12 shot

Medications: acid-reflux drugs (PPIs) and some diabetes medications (such as metformin) can interfere with B12 absorption

However, internal production can be slowed down by several factors

The reaction catalyzed by -ECS/GSH1 is considered the rate-controlling step of GSH synthesis, and the activity of this enzyme is regulated by cellular levels of cysteine and glutamic acid, and feedback inhibition by -EC and GSH ( Figure 1 GSH1 (EC 6.3.2.2) is exclusively present in plastids, while GSH2 (EC 6.3.2.2) has dual localization in plastids and the cytosol, both encoded by a single gene ( 2 O 2 and organic hydroperoxides, as well as their involvement in regulating cellular redox homeostasis by maintaining thiol/disulfide or NADPH/NADP+ ratios ( Deficiency in the activity of either GSH1 or GSH2 impairs GSH production, negatively impacting plant growth and development
