IRON: Low iron can
cause Tiredness
Tiredness can be a symptom of many different health problems
from mild to severe. If you have unexplained tiredness the first
step is to have a complete check up with your doctor to rule out
any major health problem. Tiredness is so common in our modern
lifestyles that many people simply accept it as ‘normal’ and
continue to push themselves and ignore what their body is
telling them. It is a symptom that something is not quite right,
listen to it and do something about it!
Recurrent and frequent tiredness is a symptom that you are not
at your optimal health. Even if you have been checked medically
and nothing is ‘wrong’ this indicates you are not ‘sick’. The
term ‘not sick’ is completely different to being at your
‘optimal health’. If you have optimal health you feel energetic
(physically and mentally) not tired and lethargic.
Refer to the Nov newsletter issue Part 1 of ‘why am I so tired?’
related to magnesium deficiency. The second most common
nutritional reason is iron deficiency. Up to 40% of females of
childbearing age do not receive the RDA of iron (this includes
teenagers).
If you are tired,
pale and have any of the following; weakness, breathless on
exertion, have dizzy spells, bleeding gums, heart beats faster
or have palpations, headaches, low immunity, sore tongue,
nausea, loss of appetite, faintness then you are probably low in
iron.
Other less well know symptoms can be craving for ice or cold
drinks, spoon shaped finger nails and brittle hair.
It is more common in childbearing aged females (due to loss of
blood from menstruation), pregnancy, breastfeeding, vegans and
vegetarians also endurance athletes, young children and
teenagers (with poor nutritional habits and periods of rapid
growth) & the elderly.
Firstly have a blood
test; ask your doctor for the results of your haemoglobin and
ferritin levels.
Haemoglobin is the iron in your red blood cells and Ferritin is
the iron ‘stores’ of the body. Ferritin ranges usually above 20
(ideally you should be over 60), if you are under 60 &
experiences the above symptoms I would recommend dietary changes
and a iron supplement.
Biochemical iron deficiency may not show up on a blood test. 1
in 12 women and teenage girls in Australian has biochemical iron
deficiency but only 25% of these show up on a blood test as
‘anaemic’. Hence 75% have problems of iron metabolism but are
not classified as ‘anaemic’ medically.
It is important to consider your symptoms and results of the
blood test. If you are on the lower side of ‘normal’ ranges with
iron deficiency symptoms then you need to check you iron dietary
intake & may need an iron supplement.
Most doctors recommend iron supplements which are inorganic form
(such as ferrous sulfate form). This is one area I would
strongly advise against (& there are a number of reasons why).
These inorganic forms of iron interfere with the absorption of
Zinc and Vitamin E both of which are very important especially
in pregnancy.
The best natural form iron supplement to take is called iron
diglycinate. This form of iron is almost 100% absorbed (unlikely
many other forms of iron). It does not cause the common side
effects of constipation.
Many inorganic forms of iron AND some natural forms such as iron
chelate interfere with your body’s ability to absorb other
minerals (especially calcium & zinc). Iron diglycinate does not
interfere with other minerals and can be taken with meals
Sometime being low in iron is due to deficiency in other
nutrients (called cofactors) these are folic acid, B12, B2, B6
and Vitamin C. These nutrients improve absorption of iron and
the body’s use of iron after it has been absorbed. So it is best
to take an iron supplement with all these cofactors included.
Herbs Withania, Codonopsis & Chickweed have been clinically
tested to improve blood iron levels.
Tissue salt Ferr phos also helps improve absorption of iron from
food and supplements.
Hence I often recommend iron supplements that contain these
herbs especially if your body has difficulties absorbing iron.
