B Complex Vitamins
DESCRIPTION
The eight true B vitamins are individually involved in co-enzyme
systems necessary for the release of energy from fats, carbohydrates,
proteins and alcohol. Together with Vitamin C , B vitamins
are water-soluble, and are leached into cooking fluids. To
conserve water-soluble vitamins, utilise vegetable cooking
water in soups, gravies and sauces.
THE ROLE OF INDIVIDUAL B
VITAMINS
B1 - Thiamin
The major deficiency disease
is beri-beri, now confined to developing countries. Minor
deficiencies show as Depression, irritability, lack of concentration
and memory loss. Active people need more Thiamin than those
with a sedentary lifestyle. Involved in the release of energy
from carbohydrate.
Best sources: Pumpkin seeds,
unpolished rice and nuts. Enemies: Heat, alkali.
B2 - Riboflavin
Deficiency shows as sore,
burning lips; oily Skin around the nose; or itchy, burning
Eyes. Riboflavin is a bright yellow colour, which makes it
useful as a food colouring, but it may cause a harmless colouration
of the urine. Involved in the co-enzymes necessary for converting
proteins, fats and carbohydrates into energy. Useful for cracked
lips and other skin conditions.
Best sources: Yeast extract,
Wheatgerm, cheese.
Enemies: Heat, alkali.
B3 - Niacin (amide)
Major deficiency disease
is pellagra. Minor deficiency shows as tiredness, Depression
and loss of memory. Niacin can be produced in the body using
tryptophan, B1, B6 and biotin. Useful for helping maintain
memory function in elderly. May be used for managing blood
fats (Niacin form only), but usually at high levels under
professional guidance.
Best sources: Yeast extract,
meat, nuts. Enemies: Food processing.
B5 - Pantothenic
Acid
Adrenal gland function and
the formation of anti-bodies involve Pantothenic Acid. B5
is part of the coenzyme A, which is involved in energy release
from all foods. Deficiency is not well defined. Fatigue, Headache,
dizziness and muscle weakness are generally associated with
minor deficiency in a B vitamin. Sometimes popularly known
as ‘anti-stress’ vitamin. Sometimes also used
for arthritic Pain.
Best sources: Nuts and seeds
Enemies: Heat, acid and alkali.
B6 - Pyridoxine
Involved in the conversion
of Essential Fatty Acids to prostaglandins, which help regulate
hormone balance. May be used to reduce Depression associated
with PMS. B6 may be used for preventing travel sickness, but
success is not 100%. Helps stabilise fluid levels through
Sodium /Potassium balance. Essential for protein and fat metabolism.
Can be depleted by the contraceptive pill, HRT, alcohol and
Smoking.
Best sources: Wheat germ
and fish Enemies: Food processing.
B12 - Cobalamin
Major deficiency is pernicious
Anaemia, a condition which can be life threatening. Vitamin
B12 relies on a substance known as ‘intrinsic factor’
for absorption. Intrinsic factor is found in the gastric juice.
B12 is needed for synthesis of DNA, metabolism of fatty acids,
and maintenance of the myelin sheath around nerves. Investigated
for use by MS sufferers. B12 may be deficient in vegans, alcoholics
or people with bacterial or parasitic Infections. B12 deficiency
may be masked if Folic Acid intake is inadequate.
Best sources: Animal products,
some algae and fortified foods.
Enemies: Alkali in cooking.
Folic Acid
Deficiency causes megaloblastic
Anaemia, more commonly found during Pregnancy.
Deficiency of Folic Acid during pregnancy may also result
in birth defects, such as spina bifida. Folic Acid is needed
for synthesis of DNA and cell division. It is most likely
to be deficient in the elderly, alcoholics and expectant mothers.
Low Folic Acid intake can result in high blood levels of homocysteine,
a factor which increases the risk of Coronary Heart Disease
and Stroke. Strangely, just as B12 deficiency can be masked
by inadequate Folic Acid , high levels of Folic Acid may also
mask a B12 deficiency.
Best sources: Liver, wheat
germ, and green leafy vegetables.
Enemies: Oxygen at high temperature.
Biotin
Involved in the metabolism
of carbohydrates, energy and fats. Biotin is important in
fat manufacture, glycogen manufacture and branched chain amino
acid metabolism. Deficiency in adults is rare, but is more
common in babies and small children resulting in the Skin
conditions seborrhoeic Dermatitis and Leiner’s disease.
May sometimes be suggested for chronic cases of Candida albicans
yeast overgrowth.
Best sources: Liver, egg
yolk, soya flour, cereals and yeast.
Enemies: Cooking methods. (Note: biotin is bound to avidin
in raw egg white, but freed on cooking).
PABA
Not a B vitamin itself,
but a co-factor. Deficiency results in Skin conditions, such
as Vitiligo (loss of skin pigmentation), Eczema or irritability
and Depression. PABA appears to be involved in the metabolism
of Amino Acids and red blood cells and is part of the structure
of Folic Acid . May have protective use against UV radiation,
but only when applied to skin in sun lotions.
Best sources: Liver, eggs,
Wheatgerm and molasses.
Enemies: None known.
Choline & Inositol
Choline and Inositol are
not B vitamins but B complex factors which can be made in
the body. Choline stimulates the production of Lecithin, and
is also part of the neurotransmitter acetylcholine which is
vital to nerve impulse transmission. As an emulsifier, people
with Atherosclerosis, Angina, thrombosis, Stroke, high blood
pressure, senile dementia and Alzheimer’s disease may
benefit from a supplement.
Best sources: Liver, Lecithin,.
Enemies: Food processing
Why Choose a B Complex Supplement?
As a general supplement,
a B complex is especially useful for:-
People who are under Stress
- to replace the B vitamins used in a stress situation, for
example, increase in demand on energy release, adrenal health
and the health of the nervous system - B5 and B6.
Vitamin C complements B Vitamin A ctivity as it is involved
in the formation of corticosteroids in the adrenal gland.
The antioxidant nature of Vitamin C may also be of benefit
to help quench free radicals produced as a by-product of stress.
Active people, sportsmen
and women, body builders, cyclists etc. because the more active
a person is, then the more B vitamins they will need in the
conversion of fats, carbohydrates and protein to produce energy
- B1, B2, B3, B5 and B6.
Tired people are often slightly deficient in B vitamins. This
may be through a poor diet. Refined or processed foods are
denatured of essential nutrients, trace Elementss and B complex
vitamins. Large numbers of the population in the western world
consume processed, refined foods with poor nutrient value.
Skin, hair, Eyes and general digestive health, because of
the ‘energy’ factor, all of these will suffer
if insufficient energy is being produced in the cells. Structural
integrity of skin, thickness and colour of hair - biotin and
PABA.
Maintaining health of red blood cells - Folic Acid , B12 and
PABA.
Maintaining oral health and mucous surfaces of digestive tract
- B1, B2 and Folic Acid .
Brain function - choline, inositol, Niacin , B1, B5 and B6.
