Below is general information about the safety of the known ingredients contained in the product Vanadium-250. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally and appropriately. Vanadium is safe when taken in amounts below the tolerable upper intake level (UL) of 1.8 mg daily (7135).
POSSIBLY UNSAFE ...when used orally in high doses. Taking more than the tolerable upper intake level (UL) of 1.8 mg daily can increase the risk of gastrointestinal side effects and theoretically, kidney toxicity (7135). In some cases, patients with diabetes have used very high doses (100 mg daily) safely for up to 4 weeks (3055,3056,3057). However, there is concern that prolonged use of high doses might cause serious side effects including kidney damage (7135). Doses of 22.5 mg daily for five months can cause cramps and diarrhea (3012).
CHILDREN: LIKELY SAFE
when used orally in amounts found in foods (7135).
There is insufficient reliable information available about the safety of vanadium when used in amounts greater than those typically found in foods.
PREGNANCY: LIKELY SAFE
when used orally in amounts found in foods (7135).
PREGNANCY: POSSIBLY UNSAFE
when used orally in medicinal amounts.
Epidemiological research has found that increased urinary levels of vanadium are associated with an increased risk of both term and preterm premature rupture of membranes (PROM). When comparing tertiles of urinary vanadium levels, patients in the middle tertile had 1.66 times the risk of term PROM when compared with the lowest tertile, and those in the highest tertile had 3.75 times the risk. For preterm PROM (rupture prior to 37 weeks' gestation), those in the highest tertile had an 8.14 times increased risk when compared with those in the lowest tertile (99052). Epidemiological research has also found that higher prenatal serum levels of vanadium are associated with impaired fetal growth, particularly in male newborns. The risk appears greatest with vanadium exposure in the second trimester (102096).
LACTATION: LIKELY SAFE
when used orally in amounts found in foods (7135).
There is insufficient reliable information available about the safety of vanadium when used in amounts greater than those typically found in foods; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Vanadium-250. 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, vanadium might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
 Details
In vitro research shows that the sodium orthovanadate form of vanadium prolongs clotting time, likely through inhibition of thrombin and factor Xa (3054).

Theoretically, vanadium might increase the risk of hypoglycemia when taken with antidiabetes drugs.

Below is general information about the adverse effects of the known ingredients contained in the product Vanadium-250. 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, vanadium is well tolerated when taken in amounts below the tolerable upper intake level (UL) of 1.
8 mg daily. Higher doses may cause adverse effects.
Most Common Adverse Effects:
Orally: Gastrointestinal adverse effects, including abdominal discomfort, diarrhea, flatulence, and nausea, when taken at doses above the UL.
Serious Adverse Effects (Rare):
Orally: Kidney damage, when taken long-term at high doses.
Topically: Contact dermatitis and other allergic reactions in sensitive individuals.
Cardiovascular ...Higher levels of vanadium in the body have been associated with a greater risk for hypertension (107923). However, it is unclear if oral supplementation with vanadium causes elevated blood pressure.
Dermatologic ...Allergic reactions to vanadium metal have been reported (99051,102095). A 68-year-old female developed an itchy, erythematous rash, ocular pruritus, and a positive skin test to vanadium after implantation of a vanadium-containing knee prosthesis (99051). Contact dermatitis, presenting as pruritic eczema of the hand, and a positive skin patch test to vanadium was reported in a 39-year-old male who worked with vanadium-containing tools (102095).
Endocrine ...In some cases, patients with diabetes have used very high doses (100 mg daily) safely for up to 4 weeks (3055,3056,3057). However, high body levels of vanadium have been associated with an increased incidence malnutrition-related diabetes mellitus (3020).
Gastrointestinal ...Orally, vanadium most commonly causes mild gastrointestinal upset (7135). There is concern that taking doses exceeding the tolerable upper intake level (UL) of 1.8 mg per day can increase the risk of gastrointestinal side effects and possibly lead to more severe toxicity. At higher doses, vanadium frequently causes gastrointestinal effects including abdominal discomfort, diarrhea, nausea, and flatulence (3012,3055,3056,3057,12557,12558). Doses of 22.5 mg daily can also cause cramps (3012). Vanadium has also been associated with green discoloration of the tongue, which is unrelated to dose (7135).
Immunologic
...Allergic reactions to vanadium metal have been reported (99051,102095).
A 68-year-old female developed an itchy, erythematous rash, ocular pruritus, and a positive skin test to vanadium after implantation of a vanadium-containing knee prosthesis (99051). Contact dermatitis, presenting as pruritic eczema of the hand, and a positive skin patch test to vanadium was reported in a 39-year-old male who worked with vanadium-containing tools (102095).
Higher levels of vanadium in the body have been associated with a weakened immune system in children, as measured by reductions in CD3+ and CD4+ cell counts (107924). However, it is unclear if oral supplementation with vanadium causes a weakened immune system or increases the risk of infection.
Neurologic/CNS ...Orally, vanadium has been rarely associated with fatigue, lethargy, and focal neurological lesions, which are unrelated to dose (7135).
Pulmonary/Respiratory ...Severe and chronic respiratory tract disorders have been reported from occupational exposure to vanadium dusts (17).
Renal ...In some cases, patients with diabetes have used very high doses (100 mg daily) of vanadium safely for up to 4 weeks (3055,3056,3057). However, there is concern based on animal research that prolonged use of high doses might cause serious side effects including kidney damage (7135). High body levels of vanadium have also been associated with an increased incidence of kidney stones, distal renal tubular acidosis, hypokalemic periodic paralysis, and sudden unexplained nocturnal death (3020).
