bolt Effectiveness for goals
Vitamin C is essential for collagen synthesis, a protein vital for skin elasticity and structure. It also acts as an antioxidant, protecting skin from environmental damage and reducing hyperpigmentation. Topical and dietary Vitamin C contribute to brighter, healthier-looking skin.
Regular Vitamin C supplementation may slightly reduce the duration or severity of the common cold in some individuals, particularly those undergoing severe physical stress. For the general population, its preventive effects are modest. High doses after cold onset typically do not show significant benefits.
Selenium is essential for proper thyroid gland function, as it is a component of selenoproteins involved in thyroid hormone metabolism. These selenoproteins help protect the thyroid from oxidative damage and regulate thyroid hormone synthesis. Adequate selenium intake is crucial for maintaining thyroid health.
Yes, Vitamin C is a powerful antioxidant that helps protect cells from damage caused by free radicals. It neutralizes reactive oxygen species, contributing to overall cellular health. This antioxidative property is one of its primary biological functions.
Yes, selenium is a key component of several antioxidant enzymes, such as glutathione peroxidases. These enzymes play a vital role in protecting cells from oxidative damage caused by free radicals. This contributes significantly to the body's overall antioxidant defense system.
schedule Dosage, timing & forms
Generally, Vitamin C and selenium can be taken together. Some older research suggested that very high doses of Vitamin C might theoretically interfere with the absorption of certain inorganic forms of selenium (like selenite) if taken simultaneously. However, this interaction is considered less significant with organic selenium forms (like selenomethionine) and with typical supplement doses.
While generally compatible, some individuals choose to take Vitamin C and selenium at different times to be cautious, especially if taking inorganic selenium forms. For most common organic selenium supplements (e.g., selenomethionine) and typical Vitamin C doses, taking them together is usually fine. Always refer to product specific guidelines for clarity.
The Recommended Dietary Allowance (RDA) for adult men is 90 mg per day and for adult women is 75 mg per day. Supplemental doses often range from 250 mg to 1000 mg daily, depending on individual needs and product formulations. It's important to consider your overall dietary intake when determining supplement amounts.
The Recommended Dietary Allowance (RDA) for adult men and women is 55 micrograms (mcg) per day. Supplemental doses typically range from 50 to 200 mcg. It is generally advised not to exceed the Tolerable Upper Intake Level (UL) of 400 mcg per day from all sources.
Vitamin C can generally be taken at any time of day, with or without food. Some individuals prefer to split larger doses throughout the day to optimize absorption and maintain consistent levels. Taking it with food may help prevent mild stomach upset in sensitive individuals.
health_and_safety Safety & interactions
High doses of Vitamin C, typically above 2,000 milligrams (mg), can cause gastrointestinal issues such as diarrhea, nausea, and abdominal cramps. It may also lead to heartburn in some individuals. These effects usually resolve upon reducing the dosage.
Vitamin C can potentially interact with some medications, such as blood thinners (warfarin), certain chemotherapy agents, and drugs that lower cholesterol (statins). It is important to discuss any supplement use with a healthcare provider, especially if taking prescription drugs. High doses might also interfere with some diagnostic tests.
Excessive selenium intake, known as selenosis, can lead to symptoms such as hair loss, brittle nails, gastrointestinal upset, and fatigue. In severe cases, it may cause nerve damage, liver damage, or heart problems. The Tolerable Upper Intake Level for adults is 400 micrograms (mcg) per day.
Yes, for adults, the Tolerable Upper Intake Level (UL) for Vitamin C is 2,000 milligrams (mg) per day. Intake above this level increases the likelihood of experiencing gastrointestinal disturbances like diarrhea. This limit helps prevent adverse effects from excess intake.
In some susceptible individuals, very high intakes of Vitamin C (typically above 2,000 mg/day) may increase urinary oxalate excretion, which is a risk factor for kidney stone formation. However, this risk is generally considered low for most healthy individuals. People with a history of kidney stones should consult a healthcare professional.
