According to the National Institutes of Health, the Tolerable Upper Intake Level (UL) for manganese in adults is 11 mg per day, a stark indicator that 50mg of manganese is not just too much, but a dangerously high dose. This level of exposure dramatically increases the risk of manganese toxicity, a condition with severe and potentially irreversible health consequences.

The National Academy of Medicine states that for most adults, the safe upper limit of vitamin D is 4,000 international units (IU) per day, a crucial guideline for understanding what is the tolerable upper intake level for vitamin D. This limit, also known as the Tolerable Upper Intake Level (UL), is set to prevent toxicity from excessive supplementation.

For healthy adults aged 19 and older, the Tolerable Upper Intake Level (UL) for vitamin A is 3,000 mcg (micrograms) of preformed retinol activity equivalents (RAE) per day. This crucial safety measure prevents vitamin A toxicity, which can result from excessive supplement use.

According to the National Institutes of Health (NIH), no tolerable upper intake level has been established for vitamin B12 because of its low potential for toxicity, even at high doses. This is because the body, being water-soluble, excretes any excess, meaning that for most people, determining how much vitamin B12 is too much mcg is less of a concern than ensuring adequate intake.

For adults aged 19 to 50, the Tolerable Upper Intake Level (UL) for calcium is 2,500 mg per day, according to the National Institutes of Health. Exceeding this and other age-specific maximums is considered a high dose and can lead to adverse health effects.

The Tolerable Upper Intake Level (UL) for selenium in adults is 400 micrograms (mcg) per day, a threshold established to prevent adverse health effects from excessive intake. The FDA regulates selenium across various product categories to protect public health and ensure appropriate intake and labeling.

According to the National Institutes of Health, the Tolerable Upper Intake Level (UL) for supplemental magnesium for adults is 350 mg per day. Taking a supplement of 400 mg of magnesium is therefore over the recommended supplemental limit for a woman and could potentially cause side effects, depending on her individual health and the form of magnesium.

For healthy adults, the Tolerable Upper Intake Level (UL) for iron is 45 mg per day, according to the National Institutes of Health. Intake exceeding this level should only be considered under the guidance of a healthcare professional.

The National Institutes of Health has set the tolerable upper intake level (UL) for elemental zinc in adults at 40 mg per day. This limit is crucial for ensuring safety, as consistently exceeding it, especially through supplements, can lead to adverse health effects. Knowing how much elemental zinc is safe per day is essential for managing your health and supplementation wisely.

A Tolerable Upper Intake Level (UL) has not been established for riboflavin, or vitamin B2, because no toxic level has been observed from food or long-term high-dose supplements. This means there is no official daily limit for riboflavin.
