Yes, turmeric can potentially cause blurry vision, often as a symptom of low blood sugar (hypoglycemia) when taken with diabetes medication, or as a rare, serious side effect of high doses or allergic reactions, requiring immediate medical attention for symptoms like vision changes, severe headache, or trouble breathing. While curcumin (turmeric's active compound) shows promise for eye health, high doses or interactions can lead to adverse effects, including blurred vision.
Turmeric might help improve the flow of blood, which can send more nutrients to the eyes and make vision better. It can also lower swelling, which can ease pain from eye problems like uveitis, a condition that causes inflammation in the eye.
“Megadosing” – taking a dose that is many times higher than the recommended daily allowance – can result in a range of side effects. “The most common side effects of turmeric include nausea, upset stomach and diarrhea, but it may also cause allergic reactions, rash/hives, dizziness and kidney stones,” he said.
Don't take turmeric supplements if: You're taking aspirin, ibuprofen (Advil , Motrin ), or Acetaminophen (Tylenol ). Turmeric may lessen the effects of these medications. You're taking indomethacin (Indocin ).

There is some concern that products containing turmeric or curcumin (an active component of turmeric) may affect platelet function and clotting, increasing the risk of bleeding when combined with medications that have blood thinning effects such as rivaroxaban.
Anticoagulants or antiplatelets
The risk of bleeding might be increased because turmeric may interfere with clotting by decreasing platelet aggregation. Use caution when turmeric or curcumin are taken with medicines or supplements that have anticoagulant or antiplatelet (blood thinning) effects.
Many over-the-counter (OTC) supplements, such as garlic, fish oil, and ginkgo biloba, can also raise your bleeding risk. And St. John's wort may make your blood thinner less effective. Check with your pharmacist before taking an OTC supplement with your blood thinner.
Turmeric may help reduce inflammation and joint pain, and it may support heart and gut health. Safe intake of turmeric supplements is considered up to 8 g, but long-term effects are unknown. Possible side effects include nausea, diarrhea, liver injury and medication interactions.
Turmeric and vitamin D are safe to take together and may even have synergistic effects. However, there are a few things to keep in mind. It's important to choose high-quality supplements that are free from contaminants. Look for supplements that have been third-party tested for purity and potency.
Turmeric is a whole spice that provides a broad spectrum of natural compounds that work together for general wellness and culinary uses. Curcumin, the main active compound in turmeric, can be taken as a concentrated supplement to address health concerns such as joint pain and heart health.
Turmeric is generally safe in food amounts. However, in high doses or long-term use, it may cause stomach upset, nausea, or dizziness in some people. It may also interfere with certain medications, especially: Blood thinners.
“Some research results show that people who have osteoarthritis reported less joint pain when eating turmeric in recipes,” Brown says. “Turmeric's effect on mood disorders, depression and dementia have also been explored, but studies are small, so more research will reveal if there is a benefit.”
Turmeric typically stays in the body for 1–2 days, making daily intake potentially most effective. However, this duration can vary significantly due to individual differences in metabolism.
Vitamin A, also known as retinol, produces the pigments in the retina of the eyes. More importantly, it is a vital nutrient for the photoreceptors in your eyes, which determine vision quality in low-light conditions.
While not clinically proven, certain nutritional supplements have been known help get rid of eye floaters. Substances rich in anti-oxidants like turmeric and rose hips have provided relief to many. Rose hips are most commonly found in tea, and turmeric can be located in the spice aisle at your supermarket.

10 Medications and Supplements Not To Mix With Turmeric
Taking Vitamin D3 daily is generally safe and beneficial for bone health and immune function, but exceeding the recommended daily limit (usually 100 micrograms or 4,000 IU for adults) can lead to harmful calcium buildup (hypercalcemia), causing nausea, weakness, kidney stones, and even kidney damage over time, so moderation is key and consulting a doctor for personalized dosage is recommended.
Turmeric can interact with NSAIDs, aspirin, statins, diabetes meds, blood pressure meds, as well as blood thinners. Turmeric may also interact with supplements taken for the reduction of blood clots like garlic, ginkgo, and ginseng.
The Time of Day Does Not Matter
Your body can benefit from turmeric powder whether it's taken in the morning or at night.
Turmeric, primarily its active compound curcumin, shows promise for conditions like arthritis, depression, inflammatory bowel disease (IBD), and heart disease due to its strong anti-inflammatory and antioxidant properties, with studies suggesting benefits for skin disorders, metabolic syndrome, and even some cancers, though rigorous scientific proof is still developing, with traditional use for digestive and respiratory issues also noted.
There isn't one single "strongest" natural blood thinner, as several herbs and foods like garlic, ginger, turmeric, cayenne pepper, and ginkgo biloba have antiplatelet or anticoagulant properties, but their strength varies and research is ongoing. These natural options can slow blood clotting by affecting platelets or other factors, but they aren't a substitute for prescription blood thinners and can increase bleeding risk, especially with medications like warfarin. Always consult your doctor before using them.
Iron , magnesium, and zinc may bind with warfarin, potentially decreasing their absorption and activity. People on warfarin therapy should take warfarin and iron/magnesium/zinc-containing products at least two hours apart.
Possible interactions include:
