Natural Eye Care with Dr. Marc Grossman, Holistic Optometrist

Fish oil is a popular supplement, but the real question for your eyes is: do omega-3-rich foods protect your vision better than supplements? We dig into the science behind omega-3 fatty acids and age-related macular degeneration (AMD), using a 2026 study. It showed that people who consume more omega-3s are less likely to have macular degeneration.

We also walk through what AMD actually affects in the eye, including the macula’s role in sharp, detailed vision, and why different forms of AMD matter when you’re reading headlines. You’ll hear how dry AMD, wet AMD (with a...

As we age, the balance between free radical load, antioxidant defenses, and inflammation can shift in the wrong direction, which is one reason the retina becomes more vulnerable over time. We walk through what the retina does, why it needs constant oxygen and nutrients, and how oxidative stress and chronic inflammation may contribute to long-term retinal wear and tear. 

We also dig into why anthocyanins are getting so much attention in natural eye care and integrative optometry. These plant antioxidants found in blueberries, bilberries, and other deeply colored foods are being studied for their effects on inflammation, c...

Eye pressure is the number everyone remembers from an eye exam, but it’s not the whole glaucoma story. We dig into a question patients ask all the time: when is it actually important to lower intraocular pressure, and when is the bigger issue the health of the optic nerve itself? We use a simple picture to make it stick. Pressure is like water pushing on a basement wall, and the wall is your optic nerve. Lowering pressure can help, but strengthening and protecting the “wall” matters too. 

We walk through what “normal” eye pressure really means (often 10 to...

Aging puts real pressure on the retina, optic nerve, and tear system. We dig into a practical question many people over 60 are asking: can a daily multivitamin actually support healthy aging and day-to-day function, and does that translate into meaningful support for vision? We walk through new research on multivitamins and functional health, what the results do (and do not) prove, and why a basic supplement may help when appetite, food choices, medications, or digestion make it harder to cover nutrient needs.

From there, we connect the dots between eye health and the nervous system. We explain...

Blurry, hazy vision that feels like you are looking through a dusty windshield can be more than “just getting older.” We walk through cataract surgery in plain language, starting with what a cataract actually is: the natural lens turns cloudy as proteins clump together, making colors look muted and lights at night feel harsh. When that cloudiness starts blocking daily life, surgery becomes the real solution, and understanding the steps can take a lot of the fear out of the decision.

We explain what happens before the procedure, including the measurements used to pick the right intraocular lens...

Clues about your brain health might be sitting in plain sight at the back of your eye. Let's dig into a surprising idea with big implications for healthy aging: Alzheimer’s disease may be visible in the eyes before classic memory symptoms appear. Because the retina is neural tissue, the eye and brain are deeply connected. This makes retinal changes a promising area for early Alzheimer’s screening and prevention-focused care.

We walk through how retinal imaging works and why researchers are paying attention to amyloid beta plaque patterns in the retina. We also zoom out to the...

NAD+ (nicotinamide adenine dinucleotide) is one of those behind-the-scenes molecules that quietly runs the show and when it drops with age, your energy, inflammation levels, and even eye function can feel the impact. We dig into NMN (nicotinamide mononucleotide), the naturally occurring compound studied for longevity because it helps the body produce NAD+. If you’ve been curious about NMN supplements but want a clearer, grounded explanation, we walk through what it is, why it’s popular, and what the research is actually trying to solve.

We also bring the conversation straight to vision. As a holistic opto...

Vitamin C gets treated like a one-note “immune vitamin,” but the real story is bigger and far more relevant to healthy aging. We dig into what ascorbic acid actually does in the body, from collagen production and blood vessel support to antioxidant protection that matters for high-demand tissues like the brain and the eyes. If you care about preserving vision, protecting your lens, and supporting long-term cognitive health, this conversation reframes vitamin C as a daily essential, not a seasonal add-on.

We also walk through compelling research in older adults showing an association between lower plasma vitamin C le...

Your vision is much more than just your eyes. Dr. Grossman starta from a surprising truth: embryologically and neurologically, the eye is brain tissue. Given that the brain has neuroplasticity, visual function could be more adaptable than many people realize. This opens the door to a broader, more hopeful way to think about eye health.

We walk you through the two ways we can work together. The first step is a free 10 to 15 minute discovery call to find out whether our natural eye care and integrative optometry approach could help you protect your precious gift...

Your eye color can change your day-to-day comfort in sunlight and it can hint at different long-term risks, but the real story is melanin. I’m Dr. Mark Grossman, an integrative medical optometrist and licensed acupuncturist, and I walk through what melanin is, how it functions as a natural pigment inside the eye, and why it acts like an internal shield against harmful light.

We connect the science of eye pigment to practical outcomes: why darker eyes often block more UV and reduce internal glare, why lighter eyes can experience more light scatter and photophobia, and what th...

Your vision is constantly battling oxidative stress, and that fight gets harder with age. We dig into N-acetylcysteine (NAC), a widely studied antioxidant that helps your body produce glutathione, one of your most important internal defenses. If you’ve ever wondered why “free radicals” keep coming up in eye health, this conversation clarifies the chain of cause and effect.

We connect NAC to the eye conditions older people worry about most: cataracts, macular degeneration, and dry eye. Plus, we talk about retinitis pigmentosa, a rare genetic disorder. You’ll hear why oxidative stress can damage lens proteins in catar...

Your next meal or beverage might be a chance to help protect your eyesight. We walk through the exact spices Dr. Mark R. Grossman uses almost every day and why they matter for natural eye care, especially if you’re concerned about macular degeneration, cataracts, glaucoma, or stubborn dry eye from nonstop screen time. This is a practical, kitchen-first conversation from Dr. Grossman, the integrative medical optometrist and licensed acupuncturist with decades of clinical experience. 

We start with turmeric and its active compound, curcumin, a potent natural anti-inflammatory. Curcumin helps reduce inflammation associated with dry eye syndrome. It...

We explore coleus (Coleus forskohlii) and its active compound forskolin, including what research suggests about eye pressure and other vision-related uses. I also share practical safety cautions so you can think clearly about integrating an Ayurvedic herb with standard eye care.

• how forskolin may affect intraocular pressure and glaucoma risk 
• why I recommend combining options with your doctor’s plan 
• what the research suggests for dry eye symptoms...

Your eyes do not live in isolation. They are wired into your brain, your nervous system, your sleep, and your daily habits and that means “better vision” often starts with choices that look nothing like an eye chart.

We walk through the food and lifestyle routines Dr. Mark Grossman follows personally as an integrative medical optometrist and acupuncturist with decades of experience in natural eye care. We get specific about diet for eye health and brain health, including why absorption matters more than good intentions, how mindful eating (no distractions, slower chewing) supports digestion, and why an alka...

Astaxanthin is showing up everywhere, from eye health supplements to skin and brain formulas, but most people still can’t answer the basics: what is it, where does it come from, and what does the research actually suggest it can do. We walk through why seniors are at higher risk for macular degeneration, glaucoma, cataracts, and dry eye, then connect those real-world concerns to the bigger drivers behind aging and vision loss: oxidative stress and inflammation.

We explain astaxanthin as a marine carotenoid made primarily by microalgae and found in seafood like salmon, trout, shrimp, lobster, and kr...

Your eyes are not separate from your brain. Indeed, they are part of the same system. That is why we take nutrition seriously when we talk about protecting vision as you age, especially if you are worried about macular degeneration, glaucoma, cataracts, dry eye, or the slow creep of cognitive decline.

We dig into the MIND diet, a research-backed blend of the Mediterranean diet and the DASH diet for blood pressure, and explain why it is so compelling for both brain health and eye health. I break down what the science is really saying, including long-term data...

We connect the dots between brain health and vision, showing how diet, the gut–brain axis, and key nutrients protect memory and eyesight. We share evidence on Mediterranean and MIND diets, spotlight DHA, B vitamins, curcumin, and offer practical food swaps that lower inflammation.

• eyes as brain tissue and early detection via retinal scans
• diet’s role in synaptic plasticity and cognition
• gut–brain axis signals shaping mood and memory
• Mediterranean, green Mediterranean, and MIND diet insights

We explain why vitamin D3 matters for eye health, where research points across dry eye, glaucoma, macular degeneration, diabetic retinopathy, and cataracts, and how to make smart, test-guided choices. We share target intake ranges, personal practices, and a simple plan: don’t guess, test.

• vitamin D3 as a hormone shaping inflammation, immunity and oxidative stress
• widespread deficiency due to limited sun, diet and indoor life
• target serum 25(OH)D levels and common intake ranges for seniors
• links between low D and dry eye symptoms
• associations with glaucoma risk and optic nerve resilience
• protective sig...

We explore why cataracts form, what your lens needs to stay clear, and how diet, supplements, and habits can reduce risk and improve outcomes before and after cataract surgery. We also cover dry eye prevention around cataract procedures and how to protect the retina from increased light exposure.

• reasons cataracts develop and timing across ages
• nutrients that support glutathione and lens proteins
• role of carotenoids in filtering blue and UV light
• evidence on fruit and vegetable intake and risk
• lifestyle changes, including exercise and smoking cessation
• preparing for surgery and preventing dry eye

Vision declines quietly, long before most of us notice it. We pull back the curtain on two daily supplements—resveratrol and ubiquinol—that work at the cellular level to protect the retina, optic nerve, and lens while supporting heart health and longevity. Drawing on decades of integrative eye care, we explain how resveratrol’s antioxidant, anti-inflammatory, and neuroprotective properties help in glaucoma, cataracts, and macular degeneration, and why ubiquinol, the active form of CoQ10, is a powerhouse for mitochondrial energy and cellular resilience.

You’ll hear why statins can lower CoQ10 levels and how switching to ubiquinol can bett...

In this episode, we explore tudca, a promising neuroprotective nutrient that may help preserve photoreceptors and stabilize visual signaling across several retinal diseases.
