I have been asked many times over the years by
clients, friends, and acquaintances what supplements I recommend
that they take to improve their health or improve their exercise or
sports performance. Much of the time, when people think or talk
about supplements they are referring to products that they see in
GNC, the Vitamin Shoppe, or in television commercials. In my
opinion, most of those products are a waste of money and provide
very little benefit; just because a bodybuilder or professional
athlete endorses a product does not mean it does what it is
purported to do or is worth buying. At Total Results, we recommend
that clients consume a largely whole-food diet in order to optimize
their health and get the most out of their workouts. However, even
with adherence to the best diet there may be some gaps that need to
be filled in. This is where the right supplementation can make a
huge difference.
Most of the vitamins, minerals, and trace
elements that our bodies need are best absorbed through our diet,
but some of them are very difficult to obtain through food alone. I
have narrowed it down to four (or five) supplements that I believe
most people can derive great benefit from if they take on a regular
basis.
Zinc is an essential mineral that 100
different enzymes in the body depend upon in order to bring about
biochemical reactions. It is involved in skin repair and
in making DNA (the carrier of genetic information), and protects
against cellular damage. Zinc is also critical for immune function.
Low zinc levels have been associated with increased susceptibility
to pneumonia and worse outcomes for COVID-19 patients. Zinc can be
found in beef and some seafood, but most people do not consume
enough of these foods to meet the body's requirement. Some symptoms
of a zinc deficiency include hair loss, loss of appetite, open
sores that will not heal, and a lack of alertness. The recommended
daily allowance (RDA) of zinc is 8 mg for adult women and 11 mg for
adult men, and toxicity can occur if you exceed 50 mg per day. Most
brands that you find at a grocery store will suffice (I have had a
hard time finding it on the shelves since the spring Covid wave),
but was able to order some from a company called Nature's Bounty on
Amazon. (Note: Most Zinc Supplements indicate a dosage of 50mg,
however, zinc glutonate, the form of zinc in the Nature's Bounty
product, is about 14% elemental zince (about 7mg), and similar
precentages exist for zinc sulfate and zinc acetate found in other
zinc supplements. Therefore the 50mg indicated on labels will not
come close to toxicity levels.)
Magnesium is an essential element that
plays a pivotal role in nerve cell communication, muscular
contraction, and maintaining a normal heart rhythm, which it does
by assisting movement of potassium and calcium across cell
membranes. This element is difficult to find in food,
outside of flaxseed and pumpkin seeds. As you might suspect, a
magnesium deficiency can be characterized by abnormal heart
rhythms, numbness and tingling, and general weakness. The RDA for
magnesium is 400 mg for men and 310 mg for women between the ages
of 19-30, and 420 mg for men and 310 mg for women aged 31 and up.
Magnesium toxicity is very rare, but can occur if you take more
than 5,000 mg per day, usually due to consumption of laxatives or
antacids that are high in magnesium. Nature Made and Nature's
Bounty are good brands to use if you decide to
supplement.
If I had to pick one, I would say that Vitamin C
is the least necessary of all of these vitamins and minerals to
supplement, and is the easiest to get from food. It can be found in
broccoli, strawberries, peppers, and citrus fruits, although these
fruits can be high in sugar (which should be minimized if fat loss
is a goal). This vitamin is integral in maintenance of the
immune system, as well as maintenance of the muscles, skin, bones,
and teeth. Signs of a Vitamin C deficiency, also known as
scurvy, include dry skin, anemia, nosebleeds, bleeding gums, and
severe joint pain. The RDA for Vitamin C is 65-90 mg, with an upper
limit of 2,000 mg. If you exceed the upper limit you're unlikely to
do yourself any harm, but can experience abdominal pain and some
cramping.
Vitamin D is probably the most important
vitamin or mineral to supplement, and this is because most people
are Vitamin D deficient, or at least insufficient.
Symptoms of a Vitamin D deficiency include frequent illness,
regular fatigue, depression, and digestive issues. This vitamin can
be found in some foods, such as milk, orange juice, and fish. As I
have written about in previous articles (particularly my book
review of "The Vitamin D Solution"), this vitamin functions more as
a hormone that it does as a vitamin. Vitamin D is most effectively
made by the body through exposure of the skin to sunlight, and it
is fat soluble, meaning that it can be effectively stored in fat
cells and used by the body at a later time. Most of us do not live
in the tropics or work outdoors year-round, which is why I
recommend supplementation in conjunction with regular sensible
exposure to sunlight during the months of March through October
(when the sun angle is sufficient to allow the body to produce
Vitamin D). The RDA for Vitamin D (from some sources I have seen)
is between 600 and 800 IU (international units). This is woefully
inadequate. Based on reading I have done, I would recommend no less
than supplementing with 2,000 IU per day. I have taken 5,000 IU of
Vitamin D per day (manufactured by Nature Made) for a few years
now, and have suffered no ill effects; in fact, I have noticed a
significant improvement in my energy levels, immune health, and
overall well-being since I started supplementation. It is
impossible to achieve Vitamin D toxicity through sunlight exposure;
you would experience a severe sunburn long before that happened.
Dr. Michael Holick (author of "The Vitamin D Solution") has
administered a dosage of 10,000 IU per day of Vitamin D for several
months to patients with a severe deficiency, and they did not
experience any symptoms of toxicity.
Fish oil is the final substance I would
recommend using as a supplement to your diet. It is important to
regulate your ratio of Omega 6 and Omega 3 fatty acids; too high of
a ratio of Omega 6 to Omega 3 can increase your systemic
inflammation and lead to a higher risk of the diseases of modern
civilization (diabetes, heart disease, cancer, autoimmune
disorders). Those who eat a pre-industrial diet (such as
the one we recommend) have a ratio of around 4:1 (Omega 6 to Omega
3), while those who eat a modern Western diet can have a ratio of
upwards of 15:1. Good sources of Omega 3 fatty acids include
salmon, sardines, and mackerel, but if you do not eat at least one
or two portions of fish per week you may need to supplement. We
have sold Omapure fish oil capsules at Total Results for several
years, and many of our clients swear by them. There are some side
effects if you consume fish oil in extreme excess of what your body
needs, but two capsules twice per day is the recommended safe
dosage.
A multivitamin can help but is probably not
necessary, and some of them do not work particularly well.
Multivitamins will probably not contain a high enough quantity of
the essential vitamins and minerals that you need, and are often
not well absorbed by the body. Keep in that if you decide you want
to supplement you should check with your physician. Regular
supplementation will not make up for a poor diet, but it can give
you a better margin for error if your diet is not perfect, and I
also recommend integrating some intermittent fasting to help you
get back on track if you fall off the wagon (so to speak).
Incorporate intelligent supplementation into your lifestyle and
start seeing the difference. Here's to your health!
