Phosphorus is classified as a 'major' mineral and is second only to calcium as the most abundant mineral in the body. Phosphorus combines with calcium in the bones and teeth and is part of our DNA (or genes). Phosphorus is necessary for all cell growth as well as healthy muscle function. Dietary deficiencies of phosphorus are unknown but if a person fasts, a lack of phosphorus can lead to muscular weakness and bone softening.
Recommended Daily Intake (RDI) for phosphorus is about 1000 mgs. Phosphorus is readily available through a normal and vegetarian diet.
Overdosing. Phosphorus can only become toxic when calcium levels are extremely low (which is rare). Low phosphorous diets are usually recommended for people with kidney failure. Phosphorus intakes should not exceed 4000mg per day.
Conception, pregnancy and breastfeeding. Phosphorus is essential for the overall development of your baby and to support the pregnancy and breastfeeding. Supplementing is not required as phosphorus is readily available through a normal or vegetarian diet.
Food sources. Phosphorus is part of all cells, therefore is abundantly present in all natural foods. The richest sources are in hard cheeses, milk, yoghurt, meat, fish, chicken, eggs, legumes, breads, rice, pasta, tofu, seeds, beans, fruits and vegetables. Phosphorus is also a common food additive.
