when used orally and appropriately.
A specific product containing zeaxanthin (LUTEINofta, SOOFT Italia SpA) has been used with apparent safety in infants at a dose of 0.0006 mg daily for 36 weeks (91163). There is insufficient reliable information available about the safety of zeaxanthin at higher doses or in older children.
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately in amounts found in foods.
Zeaxanthin is found in breast milk and levels correlate with infant status (106365). There is insufficient reliable information available about the safety of supplemental zeaxanthin.
Below is general information about the interactions of the known ingredients contained in the product EyesAlive. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP2B6.
 Details
In vitro research shows that astaxanthin induces cytochrome CYP2B6 enzyme activity in human hepatocytes (32613). This effect has not been reported in humans.
|
Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.
Details
In vitro research shows that astaxanthin induces CYP3A4 enzyme activity in human hepatocytes (32613). This effect has not been reported in humans.
|
Theoretically, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity (1264). Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo (91507).
|
Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Details
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity (103191). This effect has not been reported in humans.
|
Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
Details
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib (97031). This interaction has not been reported in humans.
|
Theoretically, taking zeaxanthin with antidiabetes drugs might increase the risk of hypoglycemia.

Below is general information about the adverse effects of the known ingredients contained in the product EyesAlive. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, astaxanthin seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, red fecal color.
Gastrointestinal ...Orally, astaxanthin 6 mg daily has caused two cases of increased bowel movements and two cases of red fecal color (91736). A higher dose of astaxanthin (AstaCarox, AstaReal AB) 40 mg daily has caused severe stomach/abdominal pain in two patients (19165).
Ocular/Otic ...Canthaxanthin, another carotenoid substance that is chemically related to astaxanthin, has caused crystals in the retina and loss of visual acuity in one patient (8455). This effect has not been observed with astaxanthin, but patients who have visual changes while taking astaxanthin should stop taking it immediately.
General
...Orally, bilberry fruit, juice, and extracts seem to be well tolerated.
Most Common Adverse Effects:
Orally: Dark-colored stools, flatulence, and gastrointestinal discomfort.
Gastrointestinal
...In one small clinical trial, mild-to-moderate flatulence was reported in 33% of patients taking sieved bilberries and concentrated bilberry juice (91506).
However, the patients in this study had ulcerative colitis, and the study lacked a control group, limiting the validity of this finding. In another small clinical study of males with age-related cognitive impairment, temporary adverse gastrointestinal (GI) effects were reported in 13% of patients drinking a combination of bilberry and grape juice. However, the adverse GI effect rate was identical in patients drinking a placebo juice (110641). A post-marketing surveillance report of 2295 patients using bilberry extract (Tegens) found that 1% of patients complained of GI discomfort and less than 1% experienced nausea or heartburn (35500).
Theoretically, fresh bilberry fruit may have laxative effects. One clinical trial noted an increased frequency of bowel movements following the administration of a combination formulation containing aerial agrimony parts, cinnamon quills, powdered bilberry fruit, and slippery elm bark (35462). It is unclear if these effects were due to bilberry, other ingredients, or the combination.
Other ...Orally, bilberry may cause discoloration of feces and the tongue. In one study, a dark-bluish to black discoloration of both the feces and the tongue was observed following consumption of sieved bilberries and concentrated bilberry juice. In one patient, a slight discoloration of the teeth has also been observed (91506). In another study, 50% of patients reported dark green stools after taking bilberry extract 700 mg twice daily for 4 weeks (104194).
General ...Orally, dietary and supplemental lutein is generally well tolerated. Doses up to 20 mg daily have not resulted in adverse effects.
General ...Orally, dietary and supplemental zeaxanthin are generally well tolerated. No adverse effects have been reported in clinical research.
