The extracellular glutamate ratio in the brain is primarily controlled by excitatory amino acid transporters and vesicular glutamate transporters [41]
The RA, characterized by synovial inflammation, leads to cartilage and bone destruction, significantly impairing quality of life and increasing mortality risk by 1.5 - 2-fold compared to the general population (3)
4 Iron chelation therapies for CNS disorders via different routes Delivering therapeutic agents to the CNS requires the delivery system to be capable of penetrating the brain to reach target disease sites, facing the challenge of two barriers between blood and the brainthe BBB and the blood-cerebrospinal fluid (CSF) barrier

Here, we will discuss the role of ferroptosis in different autoimmune diseases and highlight the emerging therapeutic opportunities and associated challenges with future prospects ( Figure 2 )

A 2021 review and meta-analysis on the effects of betaine on cardiovascular markers describes a lower dose as under 4g per day, and the examined trials used daily doses ranging from 1.5g all the way up to 20g.40 Coenzyme Q10 (60mg) Coenzyme Q10 (more commonly known as CoQ10) is an antioxidant that helps the body convert food into energy and fight against free radicals.41 Too many free radicals and not enough antioxidants in the body can lead to oxidative stress, which may play a role in chronic conditions like cancer, cardiovascular disease, kidney disease, Alzheimers disease, and more.15 Though most studies use higher doses of CoQ10 (100-200mg), a dose of 60mg has shown some success in research.42 An older 2006 study, for example, found that 60mg led to a significant improvement in functional status, symptoms, and quality of life in heart transplant candidates.43 And a more recent 2024 trial found that 300mg CoQ10 phytosome equivalent to 60mg CoQ10 significantly enhanced the physical performance of older adults with statin-associated asthenia (generalized weakness).44 Its worth mentioning that, even though the doses of betaine and CoQ10 are on the lower end, the liposomal delivery method may improve their bioavailability
