Eye health supplements

The Huberman Lab has discussed the role of nutrition and supplementation in maintaining and improving eye health, particularly in relation to conditions like macular degeneration and glaucoma.

For macular degeneration, studies cited by Dr. Jeffrey Goldberg in an episode of the podcast show that a mixture of vitamin C, vitamin E, zinc, copper, and beta-carotene may help decrease the progression of dry macular degeneration in more severe cases 1.

In terms of general eye health, Andrew Huberman mentions nutrients such as lutein and astaxanthin as having potentially positive effects. He suggests that while lutein might not improve vision for those with normal eyesight or a low degree of macular degeneration, it could support vision in moderate to severe cases 2. Astaxanthin has also been shown to have positive effects on skin quality 3.

For patients at the end of treatment options for glaucoma, high dose vitamin B3, also known as nicotinic acid or nicotinamide, is discussed by Dr. Jeffrey Goldberg. It's part of the NAD synthesis pathway and has shown promise in improving retinal function in limited trials 4.

Dr. Huberman stresses consulting with an ophthalmologist or physician before taking supplements and mentions that research in this area holds promise but is ongoing. He also warns against forsaking proven prescribed treatments for unproven alternatives 2 3 4.

Andrew Huberman discusses red light and its benefits across various contexts such as neuronal function, shift work, melatonin production, cortisol levels, photophobia, and alertness. Here are some main points regarding red light requirements for your health:

1. Time of Day: The use of red light early in the day, within three hours of waking, is recommended for improving neuronal function. Red light can also be beneficial late in the day or during the night, for instance, for shift workers who need to stay alert and want to avoid disrupting melatonin production or increasing cortisol 1.

2. Inexpensive Solutions: Importantly, Dr. Huberman suggests that inexpensive red light bulbs can be effective and are readily available online; there's no need for costly specialized equipment. These can be used anytime to remain awake, especially if experiencing photophobia 2.

3. Safety and Usage: To avoid damaging the eyes, the red light source should be of low enough intensity that it's not painful to look at. If a light causes discomfort or a need to squint, it's too bright. You're responsible for your own health and should consult with an optometrist or ophthalmologist before engaging in any extensive red light protocols 3.

   Andrew explains how red light can improve neuronal function when used early in the day, and can also be beneficial for shift workers who need to stay awake at night. Red light, if sufficiently dim, does not inhibit melatonin production or increase cortisol at night, making it the preferred light source for those who need to work late.

4. Evening Routine: Using red light bulbs in the evening, particularly in rooms like the bedroom, has been suggested as a cost-effective method to dim the environment and support better sleep by minimizing stimulating blue wavelengths and reducing cortisol levels 4.

5. Specific Protocols: Some protocols that involve looking at red light panels for two to three minutes every morning for a period of two weeks or more could be beneficial for those older than 40, potentially improving vision by enhancing mitochondrial function in the photoreceptors 5.

6. Red Light for Eye Health: Early in the day, flashing red light into the eyes may help offset age-related macular degeneration through improved mitochondrial function in the photoreceptors, although it's essential to do this carefully and at a safe intensity 6.

In summary, red light therapy, when used correctly, has potential health benefits in terms of enhancing alertness, aiding shift work schedules, reducing the effects of photophobia, and promoting eye health. Safety is crucial, and it's important to consult healthcare professionals before starting any new health regimen involving light therapy.
