Below is general information about the safety of the known ingredients contained in the product Vision Health. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when acerola fruit is used orally and appropriately. Acerola fruit contains an average of 2000 mg vitamin C per 100 grams of fruit, although this content varies widely. Acerola fruit should be consumed in amounts that do not provide more vitamin C than the tolerable upper intake level (UL) of 2000 mg per day for adults (4844).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using in amounts greater than found in foods.
LIKELY SAFE ...when used orally and appropriately in amounts commonly found in foods. Bilberry has Generally Recognized As Safe status (GRAS) for use in foods in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately for medicinal purposes. Bilberry fruit extracts have been used with apparent safety in clinical trials at a dose of up to 160 mg daily for up to 6 months (39,40,8139,9739,14280,35472,35510,35512,103190,104192,104195). A higher bilberry extract dose of 1.4 grams daily has been used with apparent safety for up to 4 weeks (104194). Whole bilberries or bilberry juice have also been consumed with apparent safety in quantities of 100-160 grams daily for up to 35 days (35463,91506).
POSSIBLY UNSAFE ...when the leaves are used orally in high doses or for a prolonged period. Death can occur with chronic use of 1.5 gram/kg daily (2).

Below is general information about the interactions of the known ingredients contained in the product Vision Health. 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, the antioxidant effects of acerola might reduce the effectiveness of alkylating agents.
 Details
Acerola contains vitamin C, an antioxidant. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as alkylating agents (391). In contrast, other researchers theorize that antioxidants might make alkylating chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.
|
Theoretically, concomitant use of acerola with aluminum salts might increase the amount of aluminum absorbed.
Details
Acerola contains vitamin C. It is thought that vitamin C chelates aluminum, keeping it in solution and available for absorption (10549,10550,10551). In people with normal renal function, urinary excretion of aluminum likely increases, making aluminum retention and toxicity unlikely (10549). However, patients with renal failure who take aluminum-containing compounds, such as phosphate binders, should avoid acerola in doses that provide more vitamin C than the recommended dietary allowances.

Theoretically, the antioxidant effects of acerola might reduce the effectiveness of antitumor antibiotics.
Details

In contrast, other researchers theorize that antioxidants might make antitumor antibiotic chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.

Theoretically, acerola might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Details
Acerola contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels (3046). However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion (10588,10589). The vitamin C content of acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and aspirin is unlikely.
|
Theoretically, concomitant use of acerola with estrogens might increase estrogenic effects.
Details
Acerola contains vitamin C. Increases in plasma estrogen levels of up to 55% have occurred under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products (129,130,11161). It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall (129,11161). When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements (11161).
|
Theoretically, acerola might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Details
Acerola contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption (11566). This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time (9804,9806). Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant (9805,9806,11566,11567). The vitamin C content of acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and warfarin is unlikely.

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.
|
Consuming sweet orange with celiprolol can decrease oral absorption of celiprolol.
Details
A pharmacokinetic study in healthy volunteers shows that celiprolol levels, after a single dose of 100 mg, are decreased by up to 90% in people who drink sweet orange juice 200 mL three times daily. It's not known if lower consumption of sweet orange juice will have the same effect. Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (12115,17603,17604). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).
|
Consuming sweet orange juice with fexofenadine can decrease oral absorption of fexofenadine.
Details
Clinical research shows that coadministration of sweet orange juice 1200 mL decreases bioavailability of fexofenadine by about 72% (7046,17604). In an animal model, sweet orange juice decreased bioavailability of fexofenadine by 31% (17605). Fexofenadine manufacturer data indicates that concomitant administration of sweet orange juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that sweet orange reduces the clinical response to fexofenadine (17603). Theoretically, this occurs due to short-term inhibition of organic anion transporting polypeptide (OATP) (7046). Recommend separating drug administration and consumption of sweet orange by at least 4 hours (17603,17604).
|
Consuming sweet orange juice with ivermectin can decrease the oral absorption of ivermectin.
Details
A pharmacokinetic study in healthy volunteers shows that taking ivermectin orally with sweet orange juice 750 mL over 4 hours reduces the bioavailability of ivermectin. This effect does not seem to be related to effects on P-glycoprotein. The effect on ivermectin is more pronounced in males compared to females (12154).
|
Consuming sweet orange juice can decrease oral absorption of OATP substrates. Separate administration by at least 4 hours.
Details
Clinical research shows that consuming sweet orange juice inhibits OATP, which reduces bioavailability of oral drugs that are substrates of OATP (17603,17604). For example, sweet orange juice decreases bioavailability of fexofenadine, a substrate of OATP, by about 72% and of celiprolol, another OATP substrate, by up to 90% (7046,12115). Since sweet orange juice seems to affect OATP for a short time, recommend separating drug administration and consumption of sweet orange juice by at least 4 hours (17603,17604).
|
Sweet orange juice seems to modulate P-glycoprotein (P-gp), which might affect the blood levels of P-gp substrates.
Details
Animal and in vitro research suggest that orange juice extract inhibits drug efflux by P-gp, increasing absorption and levels of P-gp substrates (12116,15327). In contrast, pharmacokinetic research in humans shows that drinking large amounts of sweet orange juice decreases absorption and levels of the P-gp substrate celiprolol. This suggests that orange juice actually induces drug efflux by P-gp or affects drug levels by another mechanism such as inhibiting the gut drug transporter called organic anion transporting polypeptide (OATP) (7046,12115). Until more is known, sweet orange juice should be used cautiously in people taking P-gp substrates.
|
Consuming sweet orange juice with pravastatin can increase the absorption of pravastatin.
Details
A small pharmacokinetic study in healthy volunteers shows that consuming sweet orange juice 800 mL over 3 hours, including before, during, and after taking pravastatin 10 mg, increases pravastatin levels by about 149%, without affecting pravastatin elimination. Theoretically this effect might be due to modulation of organic anion transporting polypeptides (OATPs) by sweet orange juice (14348). Sweet orange juice does not seem to affect simvastatin levels, but it is not known if sweet orange affects any of the other statins.

Below is general information about the adverse effects of the known ingredients contained in the product Vision Health. 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, acerola seems to be well tolerated.
However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Acerola has been linked with one case of anaphylaxis and one case of rectal obstruction.
Gastrointestinal ...Osmotic diarrhea and gastrointestinal upset have been reported with doses of vitamin C greater than the tolerable upper intake level (UL) of 2000 mg daily (4844). Theoretically this could occur with large doses of oral acerola. A case report describes rectal obstruction with mass consisting of partially digested acerola fruits in a 5-year-old child who had ingested an unknown quantity of fruits daily for 7 days. The child presented with vomiting, abdominal pain and distension, tenesmus, constipation, and dehydration, and required surgical disimpaction (93205).
Immunologic ...There is a case report of a 37 year old man who developed a pruritic rash, dyspnea, and tachycardia 5 minutes after drinking a mixture of apple and acerola juices. He had a history of hay fever, oral allergy symptoms with avocado, celery, walnut, and curry, and contact urticaria with latex, but tolerated apples and apple juice. IgE antibodies to acerola were identified in the patient's serum. Ultimately, cross-reactivity between a latex protein and acerola was determined (93206).
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, ornamental marigold is well tolerated in amounts found in foods.
No adverse effects have been reported when used in amounts greater than those found in foods. A thorough evaluation of safety outcomes has not been conducted. Topically, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Topically: Contact dermatitis.
Dermatologic ...Topically, ornamental marigold has been reported to cause contact dermatitis (11).
Immunologic ...Ornamental marigold can cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs (11).
General ...Orally, sweet orange juice or fruit seem to be well tolerated. Large amounts of sweet orange peel may be unsafe, especially for children. When inhaled, sweet orange essential oil seems to be generally well tolerated.
Gastrointestinal ...There have been reports of intestinal colic in children following ingestion of large amounts of sweet orange peel (11).
Neurologic/CNS ...There have been reports of convulsions in children following ingestion of large amounts of sweet orange peel (11).
