Supplement Index

Vitamins, minerals, fatty acids, amino acids, antioxidants and botanicals: what each does, the forms that matter, orthomolecular amounts, and who should be careful.

This reference comes from the Arukah Orthomolecular Nutrition Coach Certification. It is education, not medical advice: anyone on medication, pregnant or breastfeeding, or with kidney, liver, heart, thyroid or bleeding problems should involve their doctor before taking supplements. Read the full disclaimer.

This is a desk reference for the vitamins, minerals, amino acids and other supplements in common use, including every nutrient taught in the course: what it does, the forms that matter, the amounts reported in the orthomolecular literature and research, and who should not take it without a doctor.

How to use it. Doses come from Orthomolecular.org (mainly the Orthomolecular Medicine News Service, OMNS) and DoctorYourself.com, and each row names the page it came from. Maintenance is a daily amount for staying well; therapeutic is the range these sources report for a specific condition; safe limit is the point at which these sources report side effects or toxicity. Three nutrients have a named course authority whose figures lead the row: Dr. David Brownstein for iodine, Dr. Joseph Mercola for vitamin D and Dr. Carolyn Dean for magnesium; for vitamin C the standard is Linus Pauling as published on these two sites. The RDA is shown only for comparison. Where neither site gives a figure, the row gives a common amount used in research or on labels instead. The Lesson column shows where the course teaches each one; "Index only" means it is listed for reference. Where the sources disagree (calcium, copper, sodium), both views are shown. Doses are education, not prescriptions: every client on medication, pregnant or breastfeeding, or with kidney, liver, heart, thyroid or bleeding problems involves their doctor first.

Vitamins

Nutrient and forms Main benefits Orthomolecular doses Contraindications and interactions Lesson
Vitamin A — retinol, retinyl palmitate (preformed); beta-carotene (plant) Vision and night vision, skin, gut and lung linings, immunity (WHO uses it in measles) Therapeutic: 25,000 IU a day in a cited skin-cancer prevention study. Safe limit: above 15,000 IU a day only under medical supervision; Pauling put the ceiling in good health at 50,000 IU. Beta-carotene "does not cause toxicity." RDA 2,300–3,000 IU. (Vitamin A, OMNS v04n09) Pregnancy: DoctorYourself.com notes possible harm to the baby even below 20,000 IU of retinol (pregnancy); keep retinol low and follow the midwife. Liver disease, heavy drinking. Isotretinoin or acitretin. Smokers avoid synthetic beta-carotene pills. 4
Vitamin B1 (thiamine) — thiamine HCl, mononitrate, benfotiamine Turns carbohydrate into energy; nerves, heart, brain Maintenance: 25 mg. Therapeutic: 1,000–3,000 mg a day (MS protocol); 100–500 mg injections given by a doctor. RDA 1.1–1.2 mg. (OMNS v03n10, OMNS v14n15) Very safe by mouth. Alcohol, diuretics and high-sugar diets deplete it. Start high doses low; Dr. Lonsdale described temporary "paradoxical" worsening. 3
Vitamin B2 (riboflavin) — riboflavin, riboflavin-5-phosphate Energy; activates B6 and folate; recycles glutathione Maintenance: 25 mg. Safe limit: "many times the RDA is without demonstrable toxicity"; neither site gives a therapeutic figure (400 mg a day is studied for migraine). RDA 1.1–1.3 mg. (OMNS v03n10, Riboflavin) Very safe. Turns urine bright yellow. 3
Vitamin B3 — niacin (nicotinic acid), niacinamide (nicotinamide), inositol hexanicotinate Energy (NAD); mood (Hoffer); blood fats (niacin only); joints and calm (niacinamide) Maintenance: 300 mg (OMNS); start at 25 mg three times a day and add 25 mg a day until a flush, working up to 1,000–1,500 mg a day in three doses. Therapeutic: niacin 3,000–9,000 mg a day in three doses (Hoffer's usual range); 2,000–5,000 mg for cholesterol; niacinamide 2,000–4,000 mg a day in up to 10 doses for arthritis (Kaufman). Safe limit: the amount that causes nausea; Hoffer estimated a fatal dose above 200,000 mg. RDA 14–16 mg. (Niacin Saturation, OMNS v14n20, Kaufman) Liver disease or heavy drinking; avoid sustained-release niacin; liver tests at gram doses. Niacin raises blood sugar and uric acid (diabetes, gout), irritates active ulcers, lowers blood pressure. Statins, blood pressure and diabetes drugs: doctor first. Pregnancy: doctor. 3
Vitamin B5 (pantothenic acid) — calcium pantothenate, pantethine Coenzyme A; energy; adrenal hormones; pantethine for blood fats Safe limit: diarrhea and water retention only above 10 g a day.

Can lower phenytoin and phenobarbital levels. 3, 6
Biotin (B7) Hair, skin and nails; blood-sugar metabolism Neither site gives a dose; 2,500–10,000 mcg is common for hair and nails. RDA (AI) 30 mcg. Distorts many lab tests (thyroid, troponin, hormones): stop 2–3 days before blood work and tell the doctor. Anticonvulsants deplete it. 3
Folate (B9) — methylfolate (5-MTHF), folinic acid, folic acid (synthetic) DNA; red blood cells; methylation; prevents neural tube defects Maintenance: 2,000 mcg (OMNS optimum). RDA 400 mcg (600 in pregnancy). (OMNS v03n10) Always pair with B12 (folic acid can hide B12 deficiency). Methotrexate and some anticonvulsants interact.

Avoid cyanocobalamin in Leber's hereditary optic neuropathy. High doses occasionally trigger acne. 3, 6
Choline — lecithin, choline bitartrate, citicoline, alpha-GPC Acetylcholine for memory; liver fat; cell membranes; baby's brain in pregnancy Maintenance: lecithin, three or more tablespoons a day (each gives about 1,700 mg phosphatidylcholine). Safe limit: choline 3.5 g a day. (Lecithin, Choline) Fishy body odor, nausea or low blood pressure at high doses; Orthomolecular.org notes it may trigger seizures in epilepsy. 3
Inositol — myo-inositol, D-chiro-inositol Insulin signaling; PCOS; studied for panic and OCD Supplied with lecithin (about 1,000 mg phosphatidylinositol per tablespoon). Neither site gives a separate dose; 2–4 g (PCOS) and 12–18 g (anxiety studies) are research amounts. (Lecithin) Stomach upset at high doses. May lower blood sugar with diabetes drugs. Case reports of mania in bipolar disorder. Pregnancy: doctor. 3
Vitamin C — ascorbic acid; sodium, calcium and magnesium ascorbate; liposomal; IV (sodium ascorbate) Collagen; immunity; antioxidant and antitoxin; antihistamine; adrenal and brain chemistry; iron absorption Maintenance: 2,000 mg (OMNS optimum); healthy bowel tolerance 4–15 g a day (Cathcart); Pauling recommended 6,000–18,000 mg a day, at least 3,000 mg for prevention, and took 18,000 mg himself (OMNS v14n12, v06n20). Therapeutic (oral): "8,000 to 40,000 mg per day for an adult" (Saul); bowel tolerance in grams per 24 hours: mild cold 30–60, flu 100–150, mononucleosis 150–200+ (Cathcart); 6–18 g or to bowel tolerance with lysine 5–6 g and proline up to 2 g (Pauling–Rath heart therapy, OMNS v18n27); 1 g an hour at the start of a cold (Pauling, OMNS v21n11). Therapeutic (IV, licensed practitioner only): 400–700 mg/kg per 24 hours (Cathcart); Riordan test series of 15, 25 and 50 g. Safe limit: reduce to just below loose stool; "up to 50 grams per day, infused slowly, are not toxic." Other views (the course follows Pauling and Saul): Dr. Brownstein, 3,000–5,000 mg a day when healthy, doubled or tripled when ill. Dr. Blaylock prefers buffered calcium or magnesium ascorbate, 1,000 mg three times a day between meals. RDA 75–90 mg. (Practical Notes, Titrating to Bowel Tolerance, OMNS v16n07) Kidney stones (oxalate) or kidney disease; iron overload (hemochromatosis); G6PD deficiency (screen before high or IV doses). Distorts some glucose-meter and stool-blood tests. Chewables wear enamel. Sodium ascorbate adds sodium. 2
Vitamin D3 — cholecalciferol (D2 is weaker) Immunity; bone; muscle; mood and brain; calms inflammation Course authority, Dr. Joseph Mercola: sunlight first (near solar noon, large areas of skin, never burn); test 25(OH)D and aim for 60–80 ng/mL (sufficiency starts around 40). His guideline amounts: adults 5,000 IU a day, pregnancy 8,000 IU, ages 5–10 2,500 IU, under age 5 35 IU per pound, adjusted by retesting every 3–6 months. Always with magnesium and vitamin K2 (about 100–200 mcg of K2 per 1,000 IU, citing Rhéaume-Bleue; the ratio is not settled). D3, not D2. (Mercola: Vitamin D, Vitamin D resources) OMNS: 2,000 IU for basic prevention; 4,000–6,000 IU to reach 40–70 ng/mL; 5,000–10,000 IU or 60–100 IU per kg (MS protocol); safe up to 10,000 IU a day long-term; toxicity only above 150 ng/mL or above 40,000 IU a day for long periods. Other views: Dr. Blaylock, 5,000 IU to reach 65–100 ng/mL; Grant and colleagues, about 8,000 IU a day if untested. RDA 600–800 IU. (OMNS v21n04, OMNS v14n15, Supplement limits) Test 25(OH)D periodically. High blood calcium, sarcoidosis or other granulomatous disease, parathyroid disease, kidney stones or kidney disease, lymphoma. Thiazide diuretics and digoxin: doctor first. 4
Vitamin E — d-alpha tocopherol (natural), mixed tocopherols, tocotrienols; avoid dl-alpha (synthetic) Membrane antioxidant; heart and circulation (Shutes); skin; tocotrienols in cancer research (Brownstein) Maintenance: 200–400 IU natural mixed tocopherols (at least 200, perhaps 400 IU in pregnancy). Therapeutic (Shute protocol): 450–1,600 IU for coronary disease; 600–1,600 IU for thrombophlebitis and burns; start at 200 IU and raise 200 IU every 2 weeks. Safe limit: "as high as 3200 IU per day harmlessly"; no more than 1,200 IU on anticoagulants. Dr. Brownstein: delta-tocotrienol 100–200 mg a day for prevention (alpha-tocopherol may block it); Dr. Blaylock: mixed tocopherols 400–800 IU plus about 100 mg tocotrienols. RDA 22 IU. (Shute protocol, Vitamin E, OMNS v03n10) Blood thinners (no more than 1,200 IU, and only with the doctor), bleeding disorders; stop about 2 weeks before surgery. High blood pressure or rheumatic heart disease: start at 75 IU and raise slowly (Shute). Digitalis and insulin users: doctor. Take about 9 hours apart from iron. 2

Safe limit: "at any dose tried, there was no apparent toxicity" (MK-7 study). MK-4 is used at up to 45 mg in Japanese bone studies. (OMNS v19n28, OMNS v18n22) Warfarin (Coumadin): never start or stop without the doctor. Other blood thinners: ask the doctor. 4
Multivitamin-mineral — high-potency, taken with meals A base of the B vitamins, trace minerals and some vitamin D; does not hold enough vitamin C, E, D or magnesium Common amount: as labeled, split between meals (Dr. Saul takes his twice a day with food); extra C, E, D and magnesium are taken separately. Iron-containing formulas: not for men or women past menopause unless iron is low. Retinol (preformed vitamin A) in pregnancy. Vitamin K content with warfarin. Take thyroid medication 4 hours apart. Index only

Sulfa antibiotics (blocks their action). Liver problems at high doses; low blood sugar. Pregnancy: no safety data. Index only

Minerals

Nutrient and forms Main benefits Orthomolecular doses Contraindications and interactions Lesson
Boron Bone and joints; helps vitamin D and sex hormones Maintenance: 0.5–3 mg, "with 1 mg/day commonly suggested"; Dr. Saul (Masterclass) 1–3 mg for bones. Safe limit: above 100 mg a day can cause skin rash, diarrhea, nausea and lethargy. (Osteoporosis, Boron) May raise estrogen and testosterone: hormone-sensitive conditions need the doctor. Kidney disease. 5
Calcium — citrate, carbonate, from food Bones and teeth; nerves; muscles; heart rhythm Course position: food first, about 1,000 mg a day mostly from food (Dr. Saul cites the RDA of about 1,000 mg); any supplement is paired with magnesium, D3 and K2. Dr. Blaylock: "If you take calcium supplements, you should take magnesium as well," and he puts adequate calcium at about 600 mg a day. If following Dr. Levy's protocol: "Never supplement calcium." (Osteoporosis, OMNS v19n36) Kidney stones, high blood calcium, parathyroid disease, heart disease: doctor first. Dr. Blaylock links supplemental calcium above 500 mg a day with prostate cancer risk and warns never to give calcium to someone low in magnesium. Take apart from thyroid hormone, iron, zinc, bisphosphonates and tetracycline or quinolone antibiotics. Thiazides and high-dose vitamin D raise calcium. 5
Chromium — polynicotinate, picolinate (avoid chromium chloride) Helps insulin move sugar into cells; steadies cravings and mood Maintenance: 200 mcg (OMNS optimum). Therapeutic: 200–400 mcg a day "if there is any breath of a hint of hypoglycemia." Safe limit: "way too much" may cause harmless skin irritation (no amount given). (OMNS v03n10, Diabetes) Can lower blood sugar: clients on insulin or diabetes drugs monitor closely with their doctor. Kidney or liver disease. 3, 5
Copper — glycinate, gluconate Red blood cells; collagen; nerve coverings; energy Course position (OMNS): 2 mg a day alongside zinc, at about 15 mg zinc to 1 mg copper. If following Dr. Levy's protocol: with normal hemoglobin and hematocrit, "NO iron or copper should ever be supplemented." (OMNS v18n30, OMNS v19n28, OMNS v19n36) Wilson's disease. Copper excess (Pfeiffer) with estrogen, birth control pills or copper pipes. Liver disease. 5
Iodine — Lugol's solution, Iodoral, potassium iodide, kelp Thyroid hormone; breast, ovary and prostate tissue (Farrow, Brownstein, Sircus) Course authority, Dr. David Brownstein: healthy adults 12.5–25 mg a day; thyroid or breast disease 25–50 mg; pregnancy and breastfeeding 12–25 mg; children 0.5–3 mg by weight; as Lugol's solution or Iodoral, always with selenium, magnesium, vitamin C and unrefined salt. Need is measured with Dr. Abraham's 24-hour iodine loading test (50 mg dose; about 90% excreted when sufficient). Bromide detox is eased by salt loading: ½ teaspoon of unrefined salt in water, then plain water. (Arukah Iodine lesson; Iodine: Why You Need It, Why You Can't Live Without It) OMNS: "adults need 2-5 mg of iodide daily"; "15-50 mg daily may be needed" for thyroid problems, fibrocystic breasts or cancer. Overdose signs: swollen salivary glands, metallic taste, rash, palpitations, diarrhea. RDA 150 mcg. (OMNS v13n14) Brownstein: "Iodine doesn't cause Hashimoto's—iodine deficiency does"; he uses iodine with selenium and magnesium in Hashimoto's. Clients with a thyroid condition, on thyroid medication, pregnant or breastfeeding, older adults, or with dermatitis herpetiformis work with an iodine-literate practitioner who monitors thyroid labs. Amiodarone and lithium. Potassium iodide with ACE inhibitors or potassium-sparing diuretics can raise potassium. 5
Iron — bisglycinate, ferrous sulfate, heme iron Carries oxygen in red blood cells; energy Course position (OMNS): no routine dose; supplement only for lab-confirmed anemia, with the doctor. If following Dr. Levy's protocol: no iron at all when hemoglobin and hematocrit are normal; he regards ferritin above 25 ng/mL as the start of iron excess. Safe limit: a fatal dose for a child "could be as little as 600 milligrams." (OMNS v19n28, OMNS v19n36, Iron) Never without labs (ferritin, iron panel). Hemochromatosis, thalassemia, frequent transfusions. Lock it away from children. Take apart from thyroid hormone, calcium, zinc, vitamin E and some antibiotics. 5
Lithium (low-dose) Mood stability; studied in drinking water Maintenance: "'Natural' lithium dosage - 150 micrograms daily" (Werbach). Drug doses (hundreds of milligrams) are prescription only. (Werbach) Drug-dose lithium needs blood-level testing. Kidney or thyroid disease; diuretics, NSAIDs and ACE inhibitors raise lithium levels: doctor first. Index only
Magnesium — citrate, glycinate, malate, taurate, L-threonate, chloride, sulfate (Epsom); avoid oxide Over 300 enzymes; energy; relaxed muscles and blood vessels; heart rhythm; sleep; activates vitamin D Course authority, Dr. Carolyn Dean: about 600 mg a day: "I caution you against taking less than 600 mg/day if you want real results." She favors picometer, stabilized ionic magnesium (her ReMag product), diluted in a liter of sea-salted water and sipped through the day, and finds that oxide is only about 4% absorbed and most forms loosen the bowel before a therapeutic dose. Calcium and magnesium belong at about 1:1, not 10:1, with calcium from food (about 700 mg). (There Really Is Only One Magnesium, The Dance of Calcium and Magnesium) OMNS: 500 mg optimum; start at 200 mg and rise slowly to 600 mg in divided doses; children 100–200 mg under age 12, 300–400 mg over; toxicity "extremely rare"; optimal RBC magnesium 6.0–6.5 mg/dL. Other views: Dr. Blaylock, 500 mg twice a day with food as citrate, malate, threonate or slow-release malate; avoid aspartate. RDA 310–420 mg. (OMNS v03n08, OMNS v17n10, OMNS v18n33) Kidney failure (only if a doctor directs). Heart block, bowel obstruction, myasthenia gravis. Take 2–4 hours apart from thyroid hormone, bisphosphonates and tetracycline or quinolone antibiotics. Adds to blood pressure drugs. 5
Manganese Bone; the antioxidant enzyme SOD; blood sugar and fat metabolism Maintenance: about 4–5 mg a day. Therapeutic: 15–60 mg a day as chelate for drug-induced movement disorders (1976 study, Pfeiffer era). Safe limit: above 60 mg a day caused tremor and drooling, which stopped when the dose was lowered. (JOM 1996, JOM 1976) Liver disease (builds up and can harm the brain). Iron deficiency increases its absorption. 5
Molybdenum Enzymes that clear sulfites and uric acid Maintenance: 150–500 mcg as sold. Therapeutic: "500 mcg AM and PM" to prevent sulfite reactions. (JOM 1984) High doses can cause gout-like symptoms and copper loss. Kidney disease. 5
Phosphorus — phosphates Bones and teeth; energy (ATP); cell membranes Common amount: rarely needed; meat, dairy, grains and soft drinks supply plenty. RDA 700 mg. Kidney disease. Too much phosphorus with too little calcium weakens bone; cola drinkers often get excess. Index only
Potassium — from fruits, vegetables and juices; gluconate, citrate Heart rhythm; blood pressure; nerves; muscles Maintenance: food and juices first; about 0.5 g a day as a supplement in one study. Therapeutic: 600 mg a day as gluconate for PMS (some needed 1.2 g); 1.6–4.0 g a day for deficiency, under a doctor. Over-the-counter pills are limited to 99 mg. (JOM 1998) High potassium is "generally limited to those persons with kidney failure and Addison's disease."

Selenium — selenomethionine, selenium yeast, Se-methylselenocysteine, Brazil nuts Glutathione peroxidase; thyroid hormone activation; immunity Maintenance: 200 mcg (OMNS optimum); Dr. Saul 100–300 mcg. Therapeutic: 100–300 mcg. Safe limit: "High doses of selenium (> 400 mcg/d) can be toxic and should be avoided." (OMNS v03n10, OMNS v19n28, Congestive heart failure) Selenosis above 400 mcg a day: garlic breath, brittle nails, hair loss, nerve symptoms. One Brazil nut varies widely in selenium. 5
Silica — silicon; orthosilicic acid, horsetail, bamboo extract Collagen, hair, skin, nails and bone Common amount: 5–20 mg of silicon a day. Kidney disease. Horsetail: use only thiaminase-free products, and it is a diuretic (avoid with lithium or water pills). Pregnancy: no safety data. Index only
Sodium — unrefined sea salt or Himalayan salt Fluids; nerves; stomach acid; Brownstein uses it to help clear bromide Course position (Arukah iodine lesson): use unrefined sea salt or Himalayan salt instead of refined, iodized salt; "No-salt diets are incompatible with life" (Brownstein). During iodine supplementation: salt loading, ½ teaspoon of unrefined salt dissolved in water followed by plain water, to ease bromide detox symptoms (Farrow, The Iodine Crisis). Lesson 5. High blood pressure, heart failure, kidney disease or swelling: follow the doctor's sodium limit, including for salt loading. Salt substitutes are high in potassium. 5
Strontium — strontium citrate Bone density (studied in osteoporosis) Common amount: 340–680 mg of elemental strontium a day, taken apart from calcium.

Diabetes medication (low blood sugar). Kidney disease. Stomach upset and green tongue. Not for long-term high doses or pregnancy. Index only
Zinc — picolinate, glycinate, gluconate, citrate; oxide is poorly absorbed Immunity; wound healing; skin; taste and smell; hormones; insulin; Pfeiffer's mental-health work Maintenance: 25 mg (OMNS optimum); "safe at a dose of 20 - 50 mg"; children 15 mg. Therapeutic: 50 mg a day with 2 mg copper for immune support (Dr. Saul: 50 mg as chelate, gluconate or citrate). Safe limit: "Intake of zinc should be kept to under 100 mg per day." RDA 8–11 mg. (Zinc, OMNS v03n10, OMNS v17n02) Long-term high zinc lowers copper and iron; pair with copper as above. Nausea on an empty stomach. Never use zinc nasal sprays (loss of smell). Take apart from quinolone and tetracycline antibiotics and penicillamine. 5
