Mechanism

Synthesis from 1 study

How it works

Selenium and B vitamins reduce harmful molecules in the tissues behind the eyes, which calms down the immune response and decreases swelling and redness. This leads to measurable improvement in eye inflammation symptoms.

Most probable mechanism

In Simple Terms

Selenium and B vitamins work together to reduce harmful molecules called reactive oxygen species in the tissues behind the eyes. This lowers the activation of immune cells and fibroblasts, which decreases swelling, redness, and other signs of inflammation in the eye area.

Causal chain
1

Sodium selenite is absorbed and incorporated into selenoproteins, including glutathione peroxidases

Verified by multiple studies
which leads to
2

Glutathione peroxidases and vitamin B12 directly neutralize reactive oxygen species produced during autoimmune inflammation in orbital tissues

Supported by evidence
which leads to
3

Reduced reactive oxygen species levels decrease activation of orbital fibroblasts and infiltration of T cells and other immune cells

Supported by evidence
which leads to
4

Lowered immune cell activation reduces production of pro-inflammatory cytokines and autoantibodies targeting the thyroid and orbital tissues

Supported by evidence
which leads to
5

Decreased inflammation in orbital tissues reduces eyelid swelling, conjunctival redness, and tissue expansion, leading to improvement in clinical activity score

Similar Assertions

In areas where people have adequate selenium levels, taking vitamin B complex supplements for six months does not significantly improve quality of life or reduce symptoms of mild-to-moderate Graves’ ophthalmopathy.

In adults with mild-to-moderate Graves’ eye disease living in areas with adequate selenium levels, taking 200 micrograms of sodium selenite daily for six months leads to more patients showing improvement in eye symptoms than taking vitamin B complex alone.

Taking 200 micrograms of selenium daily for six months increases the percentage of adults with mild Graves’ ophthalmopathy who achieve no active inflammation, from one-third to just over six in ten, compared to those using only eye drops.

In people with mild to moderate Graves ophthalmopathy in areas where selenium levels are normal, taking 200 mcg of selenium daily along with vitamin B complex for six months does not lead to a meaningful change in quality of life compared to taking vitamin B complex alone.

In adults with mild to moderate Graves ophthalmopathy in areas where selenium levels are adequate, taking 200 mcg of selenium and vitamin B complex daily for three months is associated with a higher rate of self-reported quality of life improvement compared to no such supplementation, but this difference is not observed after six months.
