GLOSSARY

Cobalt is an element with an established role in cobalamin, not a salt-based route to vitamin synthesis or safe energy enhancement.

For example, record cobalt from foods and cobalamin products using actual portions; a source name without serving size does not establish daily adequacy.

Cobalt has an established role within vitamin B12, but humans do not synthesize the needed cobalamin by eating cobalt salts. Free cobalt is therefore not a vitamin replacement or an energy aid. Excess exposure to some cobalt compounds can affect the heart, thyroid or other organs. Vitamin requirements and safety must be distinguished from free-element toxicity and industrial exposure rather than treating all cobalt forms as interchangeable.

Major and trace classifications concern quantity, not relative importance. A trace element can be indispensable to an enzyme and harmful in excess. Ultratrace is likewise a quantitative description rather than evidence that every listed element has an established human requirement. Consider the evidence and reference framework instead of assigning a separate essential need from the category name alone.

Intake, absorption and body status are distinct. An apparently adequate food record can coexist with poor uptake from intestinal disease or medicines, while one low-intake day does not establish clinical deficiency. Interpret repeated food records, longer-term patterns, symptoms and suitable markers together. Fatigue after one training session is not a specific diagnostic test for an individual mineral.
