warnings and cautions
Warnings and Precautions: PNV-First should be used with caution in those with known sensitivity or allergy to soy. Vitamin D supplementation should be used with caution in those with hypercalcemia or conditions that may lead to hypercalcemia such as hyperthyroidism and those who form calcium-containing kidney stones. High doses of vitamin D can lead to elevated levels of calcium that reside in the blood and soft tissues. Bone pain, high blood pressure, formation of kidney stones, renal failure and increased risk of heart disease can occur. Iodine should be used with caution in patients with an overactive thyroid. Prolonged use of iron salts may produce iron storage disease. Folic acid, especially in doses above 0.1 mg daily, may obscure pernicious anemia, in that hematologic remission may occur while neurological manifestations remain progressive. The use of folic acid doses above 1 mg daily may precipitate or exacerbate the neurological damage of vitamin B 12 deficiency. Consumption of more than 3 grams of omega-3 fatty acids per day from all sources may lead to excessive bleeding. Supplemental intake of omega-3 fatty acids such as DHA exceeding 2 grams per day is not recommended. Avoid Overdosage.
Adverse Reactions: Adverse reactions have been reported with specific vitamins and minerals, but generally at doses substantially higher than those in PNV-First. However, allergic and idiosyncratic reactions are possible at any dose. Reported adverse events include skin ailments, gastrointestinal complaints, glucose abnormalities and visual problems.
