Fiber
Supplements (Guar Gum, Psyllium,
Pectin)
A high-fiber diet,
including the use of water-soluble
fiber such as guar gum (Indian
cluster bea plant fiber), pectin
(fruit fiber), and psyllium
(natural plant fiber), may
help type 2 diabetics regulate
blood glucose levels,
decrease insulin resistance, and
manage weight. [3]
Studies suggest that fiber
supplements may reduce the number
of calories and fat absorbed by
the body, help control glucose and
insulin effects, increase
post-meal satiety (sensation of
fullness), and decrease appetite.
[4-10]
One study has reported that guar
consumption reduced insulin
dosages and improved blood sugar
levels. [11]
Chromium
The trace mineral,
chromium, is often low in patients
with diabetes, hypoglycemia, and
obesity. Chromium can be
depleted by eating a diet high in
both refined sugar and white flour
products, and also by the lack of
exercise. Chromium assists in the
regulation of blood glucose
levels, aids in decreasing insulin
resistance, aids in weight loss,
and helps to stabilize the body's
metabolism. [12,
13]
Studies have shown
that chromium supplementation can
decrease fasting blood glucose
levels, improve glucose tolerance,
lower insulin levels, and decrease
total cholesterol and triglyceride
levels in patients with diabetes.
[14,
15]
Diabetic patients can supplement
their diets with different forms
of chromium, including chromium
polynicotinate, chromium
picolinate, GTF (glucose tolerance
factor) chromium, or
chromium-enriched yeasts. [16]
However, one animal
study showed that chromium
picolinate supplementation caused
chromosomal damage, therefore more
studies are needed to determine
its absolute safety in diabetics.
[17]
Changes in insulin requirements
may occur with chromium therapy.
Physician monitoring is advisable.
5-Hydroxytryptophan (5-HTP)
5-Hydroxytryptophan
(5-HTP), an amino acid precursor
to serotonin, may aid weight loss
in type 2 diabetics.
Low levels of serotonin (an
important neurotransmitter) have
been linked to carbohydrate
craving and may play an integral
role in the development of
obesity. Studies have shown
that 5-HTP supplementation
promotes weight loss and decreases
carbohydrate intake by promoting
post-meal satiety (sensation of
fullness) and reducing appetite,
thereby leading to reduced intake
of food. [18,
19]
5-HTP may help type 2 diabetics
control food intake and lose
weight. [20]
Vitamin C
Vitamin C is often
low in patients with diabetes,
since vitamin C transport into
cells is facilitated by insulin. [21,
22]
Vitamin C lowers blood glucose
levels, strengthens capillaries,
aids wound healing, protects
against free radicals, and
strengthens the immune system.
Studies have shown that vitamin C
supplementation can also reduce
sorbitol accumulation and
glycosylation of proteins. [23,
25]
This is especially significant,
since sorbitol accumulation and
glycosylation of proteins are
linked to diabetic complications
including eye and nerve diseases.
[26]
Zinc
Zinc levels are
often deficient in diabetic
patients. Zinc helps regulate
insulin metabolism and studies
have found that supplementation
improves insulin levels and poor
wound healing. [27-29]
Cyclo (his-pro)
Cyclo (his-pro)
extract may positively affect zinc
absorption in type 2 diabetics.
This is a significant finding,
since zinc levels are often
deficient in diabetic patients. [28]
Studies show that his-pro
supplementation decreases fasting
blood glucose levels, lowers
insulin levels, decreases
cholesterol, and increases zinc
levels in type 2 diabetics. [29,
30]
Magnesium
Magnesium levels
are often low in diabetic
patients. Magnesium is
involved in glucose metabolism.
Studies report that its
supplementation may prevent
diabetic complications such as
retinopathy and heart disease. [31-35]
Alpha-lipoic
acid (ALA)
Alpha-lipoic acid
(ALA) is an antioxidant that may
be beneficial in diabetic
patients. Studies have determined
that ALA supplementation improves
insulin and blood sugar levels and
may prevent diabetic complications
such as retinopathy. [36-42]
Changes in blood glucose levels
may occur with ALA
supplementation, so close
monitoring is advisable.
Vanadium
Vanadium, a trace
mineral, may be extremely
beneficial in diabetic patients.
Studies have found that vanadium
supplementation improves blood
glucose levels in type 2 diabetics,
and may help slow the destruction
of insulin-producing beta cells in
the pancreas. [43-48]
Essential Fatty
Acids (Evening primrose oil,
Borage Oil, Black Currant Oil)
Evening primrose
oil, which contains gamma-linolenic
acid (GLA), an omega-6 fatty acid,
may be beneficial in diabetic
patients. Because diabetes
is associated with a disturbance
in GLA metabolism, GLA
supplementation, in the form of
evening primrose, borage, or black
currant oils, may be beneficial
for proper nerve function.
It may also prevent diabetic
complications, like neuropathy. [49-55]
Gymnema
Gymnema sylvestre,
a native plant found in India, has
a long tradition, concerning the
treatment of those suffering from
diabetes. Studies have
found that gymnema supplementation
may improve insulin levels,
decrease blood glucose, aid in
weight loss, and help to
regenerate the insulin-producing
beta cells in the pancreas. [56-60]
Bitter Melon (Momordica
Charantia)
Bitter melon, also
known as balsam pear or karela
fruit, is a tropical fruit found
in Asia and South America.
This fruit has been traditionally
used in the treatment of
diabetes. Studies have
found that bitter melon contains
an insulin-like polypeptide that
may decrease blood glucose levels
and improve insulin levels. [61,
69]
Bilberry (Vaccinium
Myrtillus)
Bilberry has a
long-standing tradition in the
treatment of diabetes.
Bilberry flavonoids (anthocyanosides)
have potent antioxidant effects.
Anthocyanosides may provide for a
decrease in blood glucose
levels, strengthening
capillaries, and assist in the
prevention of diabetic
complications such as retinopathy.
[70,
71]
Biotin
Biotin, a vitamin
B-complex nutrient, aids in
glucose metabolism, improves
insulin sensitivity, and increases
glucokinase activity; the enzyme
responsible for the first step of
glucose utilization. [72]
Studies show that biotin
supplementation may decrease blood
glucose levels and prevent
diabetic complications such as
neuropathy. [73-76]
Due to the changes in the insulin
requirements with high dose biotin
supplementation, physician
monitoring is advisable.
N-acetyl
cysteine (NAC)
N-acetyl cysteine (NAC),
is a potent antioxidant and
precursor for the synthesis of
glutathione (a detoxifying agent).
Supplementation with NAC may have
beneficial effects for diabetics,
such as preserving beta cell
function in the pancreas. [77]
Coenzyme Q10
(CoQ10)
Coenzyme Q10
(CoQ10) is an antioxidant that
boosts cellular energy production
in the mitochondria, the cell's
energy powerhouse.
Supplementation with CoQ10 may
have beneficial effects for
diabetics, including the
preservation of beta cell function
in the pancreas and controlling of
blood glucose levels. [78,
79]
For best results, CoQ10 should be
taken with other antioxidants.
Carnosine
Carnosine, an amino
acid peptide, can reduce the toxic
glycosylation of proteins.
This is especially significant, as
the glycosylation of specific
proteins has been linked to
diabetic complications, including
occular and nervous system
diseases.[80]
Silymarin
Silymarin, an
antioxidant flavonoid derived from
the milk thistle herb, may have
beneficial effects for diabetics.
Supplementation with sylmarin has
been found to lower blood glucose
levels, improve liver function,
and reduce free-radical activity.
[81]
Niacin or
niacinamide (Vitamin B3)
Niacin, or
niacinamide (Vitamin B3),
supplementation may be beneficial
in diabetic patients.
Supplementation with niacinamide
can help prevent the development
of diabetes, slow the destruction
of insulin-producing cells in the
pancreas, and lower cholesterol
levels. [82,
83]
Due to niacin's side effects at
high doses, which include, skin
flushing, gastric irritation,
nausea, and liver damage, the
safest form of niacin is
flush-free niacin (inositol
hexanicotinate).
Vitamin E
Vitamin E may be
beneficial in diabetic patients.
Studies show that vitamin E
supplementation helps to enhance
insulin sensitivity and glucose
transport, reduces the risk of
heart failure, and prevents other
diabetic complications. [84-87]
