HelloPharmacist Scorecard of NightSight Formula by VisiVite
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
NightSight Formula has 5 active ingredients chosen for eye health. Lutein and zeaxanthin are carotenoids (plant pigments) that concentrate in the retina and may help protect aging vision.
Astaxanthin is another carotenoid with antioxidant properties. Saffron extract and European black currant fruit extract are added for their potential benefits to eye function and overall health.
The capsule also contains several inactive ingredients — vegetarian cellulose, sucrose, gum arabic, maltodextrin, stearate, silica, and medium chain triglycerides — which serve as fillers, binders, and flow agents.
Does it work?
Moderate evidence
Lutein is possibly effective for age-related macular degeneration (AMD) and cataracts, two common eye conditions as we age. Zeaxanthin is also possibly effective for AMD.
Astaxanthin and black currant extract lack enough reliable evidence to rate their effectiveness for the uses listed — the research simply isn't established yet. Saffron extract is possibly effective for chemotherapy-induced peripheral neuropathy and Alzheimer disease, though neither is related to the vision focus of this product.
How safe is it?
Well-documented data
Lutein from supplements is generally well tolerated at typical doses; doses up to 20 mg daily have not caused adverse effects in studies. Astaxanthin is generally well tolerated in short-term trials, but long-term safety data are limited — the most common side effects are abdominal pain, diarrhea, and red-colored stools.
Higher doses (40 mg daily) have caused severe stomach pain in a small number of trial participants. Saffron extract is generally well tolerated at lower doses and may cause gastrointestinal complaints, nausea, and sedation; rarely, anaphylaxis has been reported.
Zeaxanthin and black currant are generally well tolerated at typical supplement amounts — black currant caused mild diarrhea in a small number of patients in one large trial. Because astaxanthin and saffron extract lack adequate pregnancy and breastfeeding safety data, the product's safety data advise against their use during pregnancy and breastfeeding.
Lutein and zeaxanthin are rated Likely Safe in pregnancy and lactation. Black currant's pregnancy and breastfeeding data are not on file.
Meds to double-check
Moderate interaction found
Before you take NightSight Formula, double-check any blood pressure medicine you're on (Moderate risk of additive lowering), antidiabetes drugs (Moderate risk of low blood sugar from saffron and zeaxanthin), blood thinners or antiplatelet drugs like aspirin (Moderate risk of increased bleeding), sedatives and sleep aids (Moderate risk of extra drowsiness from saffron), antipsychotics including phenothiazines (Moderate risk with black currant), and medications metabolized by the CYP3A4 or CYP2B6 liver enzymes (Moderate risk from astaxanthin). Also mention caffeine — saffron may affect how quickly your body clears it.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is aimed at people concerned about age-related eye health, particularly AMD and cataracts. If you take blood pressure medicines, diabetes medications, sedatives, blood thinners, antipsychotics, or caffeine regularly, check your specific medications with us before starting — the interactions are significant.
Talk to your pharmacist or doctor if you're pregnant, breastfeeding, or taking any prescription drugs.

NightSight Formula by VisiVite Drug Interactions
HelloPharmacist Interaction Report
NightSight Formula by VisiVite contains five active ingredients, and we have documented interactions with a substantial number of medications.
The most serious concern is with saffron extract and blood pressure medicines (antihypertensive drugs); saffron can lower blood pressure on its own, and adding it to your blood pressure medication might drop it too far.
Read the full breakdown — every affected drug type, severity by severity
Astaxanthin may slow how your liver breaks down certain medications metabolized by CYP3A4 and CYP2B6 enzymes (Moderate severity), which could raise drug levels — examples include some statins, some cancer drugs, and some antihistamines. Saffron extract also interacts with antidiabetes drugs and CNS depressants like sedatives and sleep aids, raising the risk of low blood sugar (hypoglycemia) or extra drowsiness.
It may also affect how your body processes caffeine. Zeaxanthin has a documented interaction with antidiabetes drugs, again with a Moderate risk of low blood sugar.
Black currant fruit extract may increase bleeding risk if you take blood thinners (anticoagulants) or antiplatelet drugs like aspirin, and it may lower the seizure threshold in people on phenothiazines (antipsychotic medications).
Lutein and zeaxanthin have no interactions documented in our data, though this is not a guarantee none exist. Run your exact medications through the interaction checker on this page before you start.

For each ingredient in NightSight Formula with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Astaxanthin
Cytochrome P450 2B6 (Cyp2B6) Substrates
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP2B6.
In vitro research shows that astaxanthin induces cytochrome CYP2B6 enzyme activity in human hepatocytes. This effect has not been reported in humans.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.
In vitro research shows that astaxanthin induces CYP3A4 enzyme activity in human hepatocytes. This effect has not been reported in humans.
Saffron extract
Antidiabetes Drugs
Theoretically, concomitant use of saffron with antidiabetes drugs might increase the risk of hypoglycemia.
Some clinical research shows that taking saffron extract reduces fasting levels of glucose when used in addition to hypoglycemic agents. However, saffron powder itself has not been shown to reduce fasting glucose levels.
Antihypertensive Drugs
Theoretically, concomitant use of saffron with antihypertensive drugs might have additive effects.
Animal and human research suggests that saffron extract can decrease blood pressure.
Caffeine
Theoretically, saffron might inhibit the metabolism of caffeine.
A small clinical study suggests that taking saffron powder 300 mg in 150 mL water daily for 5 days and then taking caffeine 200 mg seems to reduce caffeine metabolite levels in the saliva and urine in males, but not females. Theoretically, this may be due to the inhibition of cytochrome P450 1A2 by saffron.
Cns Depressants
Theoretically, concomitant use of saffron and CNS depressants might have additive sedative effects.
Clinical research shows that taking saffron extract 60 mg orally daily for 26 weeks can cause drowsiness and sedation. Animal research suggests that adding saffron to hexobarbital further increases sleeping and slows motor activity.
European Black Currant fruit extract
Anticoagulant/Antiplatelet Drugs
Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects.
Phenothiazines
Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.
Black currant seed oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines, although there is no evidence that black currant seed oil causes seizures. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures.
Zeaxanthin
Antidiabetes Drugs
Theoretically, taking zeaxanthin with antidiabetes drugs might increase the risk of hypoglycemia.
In an animal diabetic model, zeaxanthin has hypoglycemic effects. However, population research has found that increasing intake of dietary zeaxanthin plus lutein does not decrease the risk of developing type 2 diabetes.
