methionine. It is needed for the transport of fatty acids into the
mitochondria in order to generate and produce energy. It also acts like an
antioxidant and helps protect the body against free radicals.

The highest concentrations of carnitine are found in red meat and dairy
products. It is also found in nuts, seeds, legumes, some fruits and
vegetables, cereals, brewer’s yeast, and carob.

What are the benefits of carnitine?
Carnitine is effective in improving the red blood cell count and hemoglobin
during hemodialysis in End Stage Renal Disease (ESRD). It is also been
used to improve symptoms associated with angina, CHF (congestive heart
failure), MIs (myocardial infarctions), infertility in men, and low birth
weight infants. Carnitine is also used to decrease fatigue and to treat
symptoms of hyperthyroidism. It is often taken to improve athletic
performance and is used as a weight loss supplement; however, there is
no consistent evidence to show that it works. Some studies show carnitine
reduces fat mass and increases muscle mass, which may contribute to
weight loss in some people.

Are there interactions between carnitine and  food, herbs or other supplements?
None known

Are there interactions between carnitine and  other medications?
Carnitine changes the effectiveness of Sintrom (acenocoumarol), thyroid
hormone and warfarin. Be cautious and talk to a doctor before starting carnitine
while on one of these medications.

What is Calcium?
Calcium is a mineral that is essential for living organisms. It is a structural
element in bones and shells and it serves as a necessary messenger in cell
physiology. For example, calcium is involved in muscle contraction, the electrical
conduction of the heart, and neurotransmitter release. Calcium combines with
phosphate to form hydroxylapatite, which is what is found in bones and teeth.

Where is Calcium found?
Calcium can be found in dairy products, such as milk, cheese, and yogurt. Other
good sources are seaweeds (kelp, wakame, hijiki), almonds, hazelnuts, sesame,
pistachio, blackstrap molasses, beans, figs, quinoa, okra, rutabaga, broccoli,
dandelion leaves, kale, fish with soft bones (canned salmon and sardines), and
fortified products like certain brands of orange juice.

Calcium is also sold in supplements. When taking calcium pills, no more than
600mg should be taken at a time for ideal absorption, and therefore the pills
should be taken throughout the day. Some of the different forms of calcium
supplements are: calcium carbonate (most common and least expensive),
calcium citrate, calcium phosphate (microcrystalline hydroxyapatite), coral
calcium, calcium lactate and calcium chelates.

What are the benefits of Calcium?
Calcium is used to prevent and treat hypocalcemia, osteoporosis, and rickets. It
is also effective in treating hyperkalemia (high potassium levels), renal failure,
and dyspepsia (calcium carbonate is used as an antacid). Calcium is also used to
treat hyperparathyroidism and to decrease PMS symptoms. For some, it reduces
the risk of colorectal cancer, fluorosis, hypercholesterolemia, hypertension,
stroke, pre-eclampsia, and weight loss.

Are there interactions between Calcium and  food, herbs or other supplements?
Vitamin D increases the absorption of calcium, whereas many fibers decrease
calcium absorption. Calcium supplements may decrease the absorption of dietary
iron, zinc and magnesium. High levels of caffeine and high levels of sodium
increase calcium excretion and may be linked to bone loss.

macular degeneration, albuminuria, atherosclerosis and peripheral arterial
disease, cancer, common cold, erythema, gallbladder disease,
hypertension, lead toxicity, and improved physical performance and

Are there interactions between Vitamin C and  food, herbs or other supplements?
Some data shows that vitamin C increases serum chromium absorption. It
also increases iron absorption. High doses of vitamin C have been shown
to decrease serum copper levels. Other evidence suggests that vitamin
B12 is destroyed by vitamin C supplements, so supplements should be
taken at least 2 hours after meals.

Vitamin D

Vitamin D

Vitamin D is a fat-soluble vitamin that helps your body absorb calcium and phosphorus, both very important for bone health. The active form of Vitamin D is called D3 or 1,25-dihydroxycholecalciferol. Optimal blood levels are 30-100 ng/mL. Where is it found? Vitamin D has many dietary sources including fatty fish (salmon, mackerel, sardines, tuna), fish liver oils, liver, fortified milk, fortified orange juice, egg yolks, edible mushrooms, irradiated mushrooms (with UVB light), and some brands of yogurt and ready-to-eat cereals. Besides these sources, the body can also manufacture its own Vitamin D through sunlight exposure. Ten to 15 minutes of exposure 2-3 times per week is adequate to obtain the needed UVB ray. It is harder to absorb Vitamin D from the skin as we get older because the body is less efficient.

What are the benefits?

Intake of Vitamin D is used to improve balance, increase muscle strength, prevent falls, reduce the risk of bone fractures, and improve osteoporosis and osteomalacia. It has been shown to play a role in immunity, inflammation, and may impact the performance and training of athletes. Research also suggests that Vitamin D prevents the development of chronic and autoimmune diseases – such as hypertension, diabetes, cardiovascular disease, rheumatoid arthritis, osteoarthritis, MS and certain cancers.

Are there interactions with medications?

Some drugs can deplete Vitamin D levels in the body and may require Vitamin D supplementation. These drugs include carbamazepine, cholestyramine, colestipol, corticosteroids, mineral oil, orlistat, phenobarbital, phenytoin, rifampin, stimulant laxatives, and sunscreens. However, high Vitamin D intake can also adversely impact certain medications and combination with the following drugs should be monitored: aluminum, atorvastatin, calcipotriene, cimetidine, cytochrome P450 3A4 enzymes, digoxin, diltiazem, heparin, thiazide diuretics, and verapamil. Some of the signs and symptoms of a Vitamin D deficiency are bone pain, muscle weakness and discomfort, decreased bone density and risk for bones fractures, and hyperparathyroidism. Side effects from overdosing on Vitamin D are nausea, vomiting, poor appetite, constipation, weakness, fatigue, and weight loss.
