Glaucoma
Glaucoma is a group of eye conditions, the common feature of which is characteristic damage of the optic nerve which transmits light signals to the brain. Left untreated, glaucoma can cause irreversible vision loss. Currently, the only established modifiable risk factor for glaucoma is elevated pressure inside the eye.

Supplement stack ranked by research quality
Primary Stack (Tier 1)
Neuroprotective effects on retinal ganglion cells; may slow visual field deterioration
May improve ocular blood flow and have neuroprotective effects; support retinal health
Supporting Stack (Tier 2)
May improve ocular blood flow; neuroprotective and antioxidant effects
Antioxidant; may transiently reduce intraocular pressure; supports eye health
Mitochondrial support; may protect retinal ganglion cells from oxidative damage
Antioxidant with potential neuroprotective effects on retinal ganglion cells
Anthocyanins support retinal microcirculation and may protect against oxidative stress
May improve ocular blood flow through vasodilation; supports nerve function
May support optic nerve health; elevated homocysteine associated with glaucoma
How It Works
Glaucoma is a group of eye conditions that damage the optic nerve, usually due to elevated intraocular pressure (IOP). It's a leading cause of irreversible blindness worldwide. The most common types are open-angle glaucoma (develops slowly, often without symptoms until significant vision loss) and angle-closure glaucoma (can be acute emergency). Vision loss from glaucoma cannot be recovered - the goal is preventing further damage.
CRITICAL: Glaucoma requires ongoing medical management. The primary treatment is lowering intraocular pressure through eye drops, laser treatment, or surgery. Regular eye exams with pressure checks and visual field testing are essential to monitor progression. Never stop or change your glaucoma medications without consulting your ophthalmologist. These supplements may provide additional support for optic nerve health but DO NOT replace IOP-lowering treatment. Acute angle-closure glaucoma is an emergency requiring immediate treatment.
* Citicoline (CDP-Choline) has the strongest evidence among glaucoma supplements. It has neuroprotective effects on retinal ganglion cells - the cells that die in glaucoma. Clinical trials show it may help slow visual field deterioration when added to standard IOP-lowering treatment.
* Omega-3 Fatty Acids may improve ocular blood flow and have anti-inflammatory and neuroprotective effects that support retinal health.
* Ginkgo Biloba may improve blood flow to the optic nerve and has antioxidant and neuroprotective properties. Some studies show benefit for visual field progression.
* Vitamin C is an antioxidant that may have a modest IOP-lowering effect, though this is likely not clinically significant for glaucoma treatment.
* Coenzyme Q10 supports mitochondrial function in retinal ganglion cells and may protect against oxidative damage.
* Alpha-Lipoic Acid is an antioxidant that may provide neuroprotection to the optic nerve.
* Bilberry Extract contains anthocyanins that support retinal microcirculation and eye health.
* Magnesium may improve blood flow to the optic nerve through vasodilation.
* B Vitamins - elevated homocysteine is associated with glaucoma risk; B12 and folate help lower homocysteine.
Expected timeline: Citicoline effects on visual function may be seen over months of consistent use. Glaucoma management is lifelong, with the focus on preventing further vision loss.

This goal refers to people with a BMI >25 attempting to reach/maintain their ideal weight. While interventions that work for people with a BMI >25 may also work for people with a lower BMI, the context is often sufficiently different that this isn't assured.
Type 2 Diabetes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.
