Iron begins to absorb from the intestine into the bloodstream within a few hours of ingestion, but full effects are often only seen after weeks of regular use.
Iron infusion is recommended when iron deficiency is severe or when iron supplements have not been effective or have caused side effects.
The effects of iron can be felt as increased energy levels and reduced fatigue after a few weeks of regular use.
Iron supplements should be taken on an empty stomach, preferably in the morning, to ensure the most effective absorption. Avoid taking iron with products containing calcium.
The recommended daily intake of iron for adults varies depending on gender and age, but typically 10-18 mg per day is recommended.
