Vitamin A = the optimal amount is 5,000 – 10,000 IU but no more! (High doses are actually
harmful, especially to the liver). You can also get your vitamin A as beta-carotene in which case more may be taken. FYI:
antibiotics, laxatives and some cholesterol-lowering drugs interfere with absorption of vitamin A.
(The B Vitamins generally work best together.)
Vitamin
B1 (Thiamin HCL) = RDA is only 1.5mg; ODI is at least 50mg. Thiamin HCL is the best form but you may also see B1
as Benfotiamine, which is an especially good form for diabetics.
Vitamin B2 (Riboflavin)
= RDA is only 1.7 mg; ODI at least 15 mg, but not 50 or higher over a long period of time as eye problems may develop. Riboflavin
is necessary for red blood cell formation, antibody production, and eye health including treating cataracts. It's also
great for treating carpat tunnel syndrome when used with the other B vitamins.
Vitamin
B3 (Niacin/Nicotinic Acid or Niacinamide) = RDA is 20 mg; ODI is 50 mg. Vitamin B3 as niacin lowers cholesterol but
may possibly produce a flush/rash/tingling sensation and high doses can elevate blood sugar levels. Vitamin B3 as niacinamide
doesn’t produce the flush effect but neither does it lower cholesterol.
Vitamin
B5 (Pantothenic Acid) = RDA is 10 mg; ODI is 50-100mg. Vitamin B5 is known as the anti-stress/energy booster vitamin.
Vitamin B6 (Pyridoxine) = RDA is 2 mg; RDA is 50-100 mg. Vitamin B6 is involved in more bodily functions
than any other single nutrient, effecting both physical & mental health. However, high doses (1,000mg per day or more)
can be toxic.
Vitamin B12 = RDA is 6; ODI is 200-400 mcg. Vitamin B12
as cyanocobalimin is the most common form, however, it is not used well by the body thus many using this form are deficient.
Vitamin B12 as methylcobalamin is a better form. This is an important vitamin especially as we age. It is often taken as a
separate stand alone supplement, especially sublingually (under the tongue).
Biotin
= RDA is 300 mcg; ODI is 400-800 mcg. Biotin is a good for cell growth, hair & skin vitamin. Biotin deficiency is rare.
Choline = no RDA; ODI is 50-200mg. Choline is great for all message system organs that play a part
in carrying messages throughout the body, like the endocrine system and nervous system. Its also good for the circulatory
system.
Folate (folacin/folic acid/pteroylglutamic acid-PGA) = RDA is 400 mcg;
ODI is 400-800 mcg. Folate is considered brain food and is important for DNA & RNA synthesis & healthy cell growth.
It’s the most important nutrient in regulating homocysteine levels, which is associated with hardening of the arteries
(atherosclerosis).
Inositol = no RDA; ODI 50-200mg. Inositol is vital for hair
growth. It has a calming effect (high doses may help treat depression & OCD) and it helps reduce cholesterol. Note that
large amounts of caffeine may deplete inositol in the body.
PABA (Para-Aminobenzoic
Acid) = no RDA; ODI 10-50mg. PABA is a basic constituent of already discussed folate. It helps protect against sunburn by
reducing the absorption of ultraviolet radiation and helps maintain friendly flora in intestinal tract. May restore gray hair
if caused by stress or nutritional deficiency.
Vitamin C (Ascorbic
Acid/Ester-C is a good form) = RDA is 60 mg; ODI is 1000-3000 mg; if pregnant, no more than 5000 mg. Avoid chewable forms
of Vitamin C because can damage tooth enamel. Vitamin C is such an important vitamin that most accept it as such. Works best/well
with E & beta-carotene; smoking seriously depletes this important antioxidant in the body, especially in the lungs.
Vitamin D = RDA is 400 IU as is the ODI. Cholecalciferol is the best and natural form of Vitamin
D3 made from sun on the skin. Vitamin D as D2 (ergocalciferol) comes from food sources, Vitamin D as D5 is the synthetic form.
It's best to get vitamin D by getting just 15 minutes of sun contact on skin each day, however, dark-skinned people or
anyone living in upper US in the winter may have harder time producing Vitamin D. Vitamin D must be activated by the liver
and kidneys so if you have problems with these, you may be at higher risk for Vitamin D deficiency diseases like osteoporosis,
prostate cancer, diabetes.
Vitamin E = RDA is 30 IU; ODI is 200 IU with 1500
as absolute max. Lesser amounts are required/beneficial for children. D-alpha-tocopherol is the best form of vitamin E followed
by rrr-alpha-tocopherol, d-alpha tocopherol acetate or d-alpha-tocopherol succinate. Not as good versions are dl-alpha-tocopherol
or all-rac-alpha-tocopherol, or any gamma-tocopherol forms. Vitamin E is very important antioxidant and deficiencies may result
in infertility in men & women, menstrual problems, miscarriages, uterine degeneration, retina damage, and neuromuscular
impairment.
Vitamin K = RDA is 80 mcg; ODI is 100-500 mcg. There are 3 main types
of vitamin K: K1 (phylloquinone or phytonadione), K2 or K3 (menadione – synthetic, man-made). K1 is the best. Essential
for bone formation & repair; produces prothrombin which is necessary for blood clotting; also good for the liver. Best
when received through diet, rather in a multi-vitamin. Good sources of vitamin K are asparagus, blackstrap molasses, broccoli,
cabbage, dark green leafy vegetables, alfalfa, green tea. Vitamin K is made by the friendly bacteria that live in our intestines.
Therefore, antibiotics, which kill these organisms, interfere with the process. Especially avoid large doses of K supplements
in the last few weeks of pregnancy. Again, best to get from food.
Bioflavonoids
are not true vitamins although may sometimes be referred to as Vitamin P. They are essential for the absorption of Vitamin
C, they reduce pain especially from athletic injuries or lower back & leg pain. The body does not produce them so they
must get through diet (fruits) or supplementation. There are many kinds: citrin, eriodictyol, various flavones, hesperetin,
hesperidin, quercetin (may treat & prevent asthma symptoms), guercetrin, & rutin. Biolfavonaid supplements often have
a mixture of several. ODI is 200-500 mg of a mixture.
Coenzyme Q10
is a vitamin-like substance that resembles the work of Vitamin E. It plays a critical role in production of energy in every
cell of the body, aids circulation, stimulates immune system, has vital anti-aging effects. Deficiencies linked to periodontal
disease, diabetes, and muscular dystrophy. Great to treat allergies & asthma, Alzheimer’s disease and other mental
function abnormalities. Also great to treat and prevent cardiovascular disease. The amount of CoQ10 found in the body declines
with age. ODI is 30-100 mg.
