Should You Take a Vitamin or Mineral Supplement?
One of the most common questions I recieveis........
Should I take a supplement?
On my last blog post one of the questions asked wasabout 'Vegan' vitamin and mineral supplements. 'Vegan' in the case of vitamins or minerals really doesn't mean a wholelot, not to say that some aren't made from animal derived ingredients, but say,vegan calcium citrate does not mean it is well absorbed, necessary, or evenbeneficial.  Different methods ofchelation of minerals have HIGHLY variable absorption rates, not to mentionthat these supplements do not have a proper balance of all other cofactorsnecessary for proper utilization of calcium anyway!  This is a highly complex balance the bodyneeds and merely taking calcium isn't going to do that for you whether vegan,chelated or whatever the case may be.  This goes for all synthetic vitamins and 'artificially' chelated minerals!  NONE of them are natural, nor are they provided in a whole complex of cofactors and regulating factors such as fiber.
I am not entirely opposed to taking a supplement fora very specific reason but in general I do NOT recommend them foreveryone.  We are meant to get all thenutrients we need in our food not from a bottle of isolated, artificiallychelated or synthetically produced vitamins and minerals.
There are many supplement companies that have gottenvery clever in their marketing, they put Whole Food supplement on thelabel.  This has fooled many consumersand in fact, all the midwives in my area recommend a specific brand of prenatalvitamins because it says whole food supplement on the label.  I cannot believe that these otherwise intelligentwomen fall for this.  The supplementincludes some dried fruits and vegetables but most or all of the actuallyvitamins and minerals do NOT come from these foods.  By including the whole food concentrates theycan call the supplement whole food, it is tricky, but an outright lie.
There are literally tens of thousands ofphytonutrients that have been discovered, and probably even more that we haveyet to discover.  All of these nutrientsincluding vitamins and minerals work synergistically together in a perfectlyorchestrated balance to promote health and wellbeing.  Whenever scientists try to make a profit byisolating or synthetically producing plant compounds in supplements we start torun into health problems.  Most peopledon't realize that Dozens of studies have found INCREASED risk of healthproblems from taking supplements.
Folic AcidI want to be very clear with this one, folic acid isa synthetically produced 'vitamin'. FOLATE is a naturally occuring vitamin compound found in green leafyvegetables and is ABUNDANT in a variety of vegetables.   We need folate and we know that in pregnancyit is critically important for preventing neural tube defects and cleft palate,however we have NO need for folic acid!
Are there risks to taking folic acid in pregnancy?
Absolutely!  Astudy published in the British Medical Journal in the December 2004 issue foundthat supplementation with folic acid increased the risk of death by 21-42% anddoubled a woman's risk of breast cancer. This study included 3487 women utilizing a trial of folic acidsupplementation, as the study unfolded researchers found higher rate of deathand cancer among women taking folic acid in about .2mg vs. 5mg. per day.
Not convinced?
Another study called the Folate After CoronaryIntervention Trial, which was conducted on 636 heart patients after thepatients had undergone placement of stents. The study reviewed health after six months of supplementation with folicacid.  The patients taking the folic acidhad significantly MORE narrowing of the arteries, increased closure of thearteries, and more major cardiac events compared to those on a placebo.
How do you ensure adequate Folate intake?
EASY!!  Greensmoothies, salads, lots of leafy green vegetables, legumes and some wholegrains are an excellent source as well!  1 Med. baked potato............12%1 cup raw spinach.................16%1 cup Romaine Lettuce.........15%1 c. broccoli...........................14%1 cup. garbanzo beans..........71%1 cup black beans...................64%1 cup quinoa cooked...............19%

What about Vitamin A?
There havebeen some organizations promoting the idea that we need preformed vitaminA.  This is absolutely not true,  the human liver cannot detoxify vitamin A andtherefore excess intake of preformed vitamin A can cause toxicity.  Are there risks to vitamin A toxicity....YES!
#1 Vitamin Atoxicity in pregnancy can cause birth defects! 
BottoLD et al. Epidemiology. 2001 Sep;12(5):491-6.
2. Research has found that supplemental vitamin A cancause calcium loss in the urine and contribute to osteoporosis.  MelhusH et al. Ann Intern Med. 1998 Nov 15;129(10):770-8.
3. A meta-analysis published in the cochrane database found increasedmortality in individuals taking Vitamin A, beta-carotene or vitamin E.  BjelakovicG et al. Cochrane Database Syst Rev. 2008 Apr 16;(2):CD007176.
The TRUTH about vitamin A, our bodies convertbeta-carotene into Vitamin A as needed! No, not ALL beta-carotene consumed is converted, we do NOT want the bodyto do that.  The body regulates theamount of vitamin A to prevent toxicity as well as prevent deficiency.  Therefore, if I consume say 8 oz. of carrotjuice which contains a lot of beta-carotene, but my body has enough vitamin Aalready, guess what?  It is NOT going toconvert it because I don't need it!!!  People misunderstand the fact that the body doesn'tconvert regular amounts of beta-carotene into vitamin A.  They believe that because at timesbeta-carotene conversion is low, this means inadequate!  This is absolutely false, the body is NOTgoing to cause itself to be deficient when sufficient beta-carotene isavailable in the diet, nor is it going to cause toxicity.  The body is highly intelligent and we mustrespect this!
Howdo you obtain enough vitamin A?
Consume lots of yellow and orange vegetables and fruits!
1 c. cubed cantaloupe.........................232%10 baby carrots.................................591%1 c. green leaf lettuce........................114%1 c. spinach........................................121%1 c. watermelon diced ........................37%1 c. butternut squash cubed................980%
Okay, do you see how this is NOT hard!  You simply eat a wide variety of fruits,vegetables, whole grains and legumes and you obtain MORE than enough nutrition!  No study has EVER found toxicity or healthproblems from consuming too much beta-carotene in foods, other than a case of anorange hue to the skin which is completely harmless at amounts of carrot juice requires ENORMOUS.
Ironsupplementation
Iron is extremely important in the body,  it is necessary to make the oxygen carryingproteins hemoglobin and myoglobin.   However, iron can also be toxic! 
A study conducted by the Department of Medicine,University of Western Ontario in Canada found that an overload of iron in thebody can produce many symptoms that may include, frequent infections, joinpain, hip pain, gastric pain, elevated liver enzymes, cessation ofmenstruation, hair loss and heart fluttering. 
Adams PC, et al.The relationship between iron overload, clinical symptoms and age in 410persons with genetic hemochromatosis. Hepatology 1997;25:162-6
A study published in Diabetes Care in 2007 evaluatedwomen with type II diabetes from 1980 through 2000 with 550 documented cases ofcoronary heart disease.  Women who hadthe highest level of heme-iron intake from red meat had  an increased risk of coronary heart diseasecompared to those with the lowest intake.  Researchers concluded that higher intake of heme-iron increase the riskof heart disease in patients with type II diabetes.  
http://www.ncbi.nlm.nih.gov/pubmed/17192341
According to a Cochrane Review excess ironsupplementation in pregnancy, or daily iron supplementation leading to highhemoglobin concentrations increased the risk of premature birth and low birth weightbabies.  It was recommended that tominimize symptoms of constipation, nausea and iron overload women supplementintermittently.  http://summaries.cochrane.org/CD009997/intermittent-regimens-of-iron-supplementation-during-pregnancy
Here again we deal with the false idea that we need toeat foods that have the highest absorption rate of iron.  This is NOT the case.  The body will regulate absorption accordingto need.  Consuming heme-iron which isonly found in red meat, chicken contains VERY little iron.  This iron CANNOT be regulated by the body andtherefore is absorbed regardless of need. Whereas in plant-based foods, non-heme iron is heavily regulated basedon iron status in the individual.  Thereare also other regulating factors such as phytic-acid, fiber and othernutrients in foods that help regulate absorption and prevent overload.  Phytic acid and fiber are NOT the enemy,phytic acid has POTENT cancer fighting properties, you can read about that inmy article on phytic acid HERE!.  Fiberalso plays a vital role in health and regulating mineral uptake is one of them.
Non-heme iron is the perfect form of iron for the humanbody, it can easily be regulated and absorbed as needed.  Can anemia develop?  Yes.  But it develops in individuals on ALL typesof diets, generally there are other factors at play rather than diet including: excessive exercise, heavy menstrual bleeding, ulcers, digestive problems, h.pylori, celiac disease, etc....
Howdo you ensure adequate Iron from Diet?
1 c. cooked spinach.......................36%1 c. lentils.......................................37%1 c. black beans.............................20%1 large baked potato......................18%1 c. raw peas.................................12%1 c. refried beans...........................21%1 c. Chard.......................................22%1/4 block tofu..................................22%1 c. tempeh......................................25%2 Tb. molasses.................................10%1 c. oatmeal........................10%

**Whatif I do become Anemic and need an iron supplement?
I recommend taking Floradix, a plant based iron that isNOT constipating and will NOT cause iron overload.

VitaminD Supplementation
Vitamin D is actually a hormone, not technically avitamin.  It is produced by the body inresponse to exposure of sunlight on the skin. In supplement form there are two types, D2 [ergocalciferol] and D3[cholecalciferol] Here we have the same idea that because something isgood, or the body needs it, more equals better! This is absolutely not true. Vitamin D's main function is to maintain blood levels of calcium andphosphorus.  Excess 
vitamin D accordingto the Mayo Clinic can cause serious side effects:

"Excess vitamin D intake may increase the risk of falls orfractures. Other potential adverse effects include increased risk of urinarytract infections, decreased appetite, weight loss, an elevated internationalnormalized ratio, hypercalcemia (increased calcium in the blood),hypercalciuria (increased calcium in the urine), hypervitaminosis D (high bloodlevels of vitamin D), elevated creatinine levels, gastrointestinal complaints,and increased cancer risk.Vitamin D toxicity can result from regular excess intake of thisvitamin and may lead to hypercalcemia, hypercalciuria, and excess bone loss.Individuals at particular risk include those with hyperparathyroidism(overactive parathyroids), kidney disease, sarcoidosis, tuberculosis, orhistoplasmosis (examples of immune disorders). Chronic hypercalcemia may leadto serious or even life-threatening complications and should be managed by aphysician. Early symptoms of hypercalcemia may include nausea, vomiting, andanorexia (appetite or weight loss), followed by polyuria (excess urination),polydipsia (excess thirst), weakness, fatigue, somnolence, headache, dry mouth,a metallic taste, vertigo (dizziness), tinnitus (ear ringing), and ataxia(unsteadiness). Kidney function may become impaired, and metastaticcalcifications (calcium deposition in organs throughout the body) may occur,particularly affecting the kidneys."
According to the Cochrane Review, Vitamin D supplementation didNOT improve bone density in healthy children in any location including the hip,lumbar spine, forearm or in the body as a whole.  http://summaries.cochrane.org/CD006944/vitamin-d-for-improving-bone-density-in-childrenOkay, so do we ALL need to take vitamin Dsupplements in the D3 form that are more highly absorbed [as some claim].  No, we do not.  IF, and only if you are truly deficient invitamin D do you really need to take any supplement of vitamin D and if you dotake D2 you may need a higher dose than if you took D3 but it really isn't abig deal in that regard.

Vitamin D production by the skin in response to sunexposure operates on a feedback loop that prevents toxicity.  We need these feedback loops and 
checks andbalances in the body in order to prevent toxicity.

Vitamin D3 or cholecalciferol is what is produced by theskin when exposed to sunlight. Vitamin D2 is produced by plants, namelymushrooms that are exposed to sunlight for 5-15 minutes produce high amounts ofvitamin D2.Technically D2 is not produced or found in the human bodynormally, however, it is converted in the body into the active forms, however,it's biological activity is about one third that of D3.

Okay, so enough of all the technical stuff, how do youobtain enough vitamin D3?   It is a goodidea to first get a blood test to determine if you even have any reason to beconcerned about your vitamin D levels.

Once you determine that you do in fact need a supplement,if you live in a climate where you can get outside even in the summer months,get outside more often!  Do not putsunscreen on until you have been in the sun for at least 7 minutes for verylight skin and up to 30 minutes for the darkest skin.    While you are striving to change your habits, you mustdecide if you want to try to bring up your D levels with D2 [vegetable source]or D3 [animal source].  I'm not going togo into an argument about which you should take as I think it is a personalchoice but make sure you determine your personal need for a supplement first.

Plantbased diets and B12
This is where the meat heads really try to discredit thathumans are physiologically herbivores and they state the vegan diet is notnatural to humans.  This is NOT the case!

We do not live in the same world we once did.  B12 is produced by bacteria, in ourgermophobic, bacteriaphobic society we have completely destroyed any abilitythe body has to obtain B12 from our natural diet.
  Research on Iranian villagerswith very little animal product intake, dairy maybe once per week and meatintake at once per month had normal B12 levels, no megaloblastic anemia amongthem and the average B12 level was 411pg.ml which is excellent consideringtheir diet.  The authors speculated thatthese remarkable results may be due to the fact that their diet is low inprotein allowing B12 producing bacteria to ascend into the ileum where it couldbe absorbed, they lived among farm animals and other areas with feces and othercontamination which could contribute to B12 levels. http://www.veganhealth.org/b12/int#fn8

We do not live in a natural environment like the Iranianvillagers, we live in a world of hand sanitizer, antibacterial soap,pesticides, herbicides, fungicides, chlorinated water, antibiotics, and thelist goes on and on and on!   In thissituation, there is no way to ensure that our own intestinal flora is capableof producing adequate B12, some individuals do not develop deficiency even on avegan diet, but some do and deficiency of B12 can cause a host of healthproblems.

I DOrecommend taking a B12 supplement!

Itabsolutely MUST be in the methylcobalamin Form!!!!

This is the only vitamin or mineral supplement that I would recommend to everyone,INCLUDING meat eaters.




Methylcbalamin can be more expensive this one at amazon is a great value and is a good quality.
Okay, basically the moral of the story is DO NOT indiscriminatelytake vitamin or mineral supplements!  Ifyou really want to take something to help you ensure adequate levels Irecommend a couple of 100% whole foods to help:
Vitamineral green
