Eye Health

Eye health refers to the proper function of all aspects of the eye that contribute to vision and tear production including the cornea, pupil, lens, retina, optic nerves, and tear glands. Eye health is important to prevent eye diseases like macular degeneration and glaucoma.

How It Works

Eye health supplements support vision and help protect against age-related eye diseases like macular degeneration and cataracts.

KEY EYE CONDITIONS:

•Age-related macular degeneration (AMD)
•Cataracts
•Dry eye syndrome
•Glaucoma
•Diabetic retinopathy

THE AREDS FORMULA:

The Age-Related Eye Disease Studies (AREDS/AREDS2) established a specific formula for people at risk of AMD:

•Vitamin C: 500mg
•Vitamin E: 400 IU
•Zinc: 80mg (with copper 2mg)
•Lutein: 10mg
•Zeaxanthin: 2mg

LIFESTYLE FOR EYE HEALTH:

•Don't smoke (major risk factor for AMD)
•Wear sunglasses (UV protection)
•Eat leafy greens (natural lutein)
•Manage blood sugar and blood pressure
•Regular eye exams
•Take breaks from screens (20-20-20 rule)

WHO BENEFITS MOST:

•Intermediate AMD (AREDS formula most proven)
•Family history of AMD
•Smokers or former smokers
•Dry eye sufferers (omega-3)

* Lutein and zeaxanthin are the most evidence-based supplements.

* AREDS formula specifically for AMD risk.

* Regular eye exams remain essential.

Expected timeline: Macular pigment increases over 3-6 months. AREDS benefits seen over years of use.

Type 2 Diabetes

7 shared supplements · 868 outcomes

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.

Cognitive Improvement

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.

Skin Health

Overweight is characterized as having a body mass index (BMI) of 25 to 29.9. Having overweight is associated with increased risk of conditions such as cardiovascular disease. However, this may not be the case in people with increased lean mass (e.g., athletes or weight lifters).

High Blood Pressure

High blood pressure is when the force of your blood pushing against the walls of the arteries is consistently too high. High blood pressure is often caused by an unhealthy lifestyle, although it can result from other medical conditions as well.
