Kurt's TSH of 4.2 mIU/L is sufficient to increase LDL cholesterol by 20-30% and increase the (relative) risk for heart attack 3-fold.
Kurt's thyroid was also palpably enlarged. While it was just barely visible--just a minor bulge in the neck (in the shape of a bowtie), it could be clearly felt when I examined him.
I asked Kurt to add 500 mcg of iodine every day. Three months later, another thyroid panel showed:
Kurt's thyroid function normalized to nearly ideal levels just with iodine replacement. (The free T3, while improved, remains low; an issue for another day!)
I see this response with some frequency: low-grade goiter and apparent hypothyroidism (low thyroid function) that responds, at least partially, to iodine replacement. In Kurt's case, iodine replacement alone normalized his thyroid measures completely.
With improved thyroid measures, Kurt also felt better with renewed energy and a 22 mg/dl reduction in LDL cholesterol.
Make no mistake: Iodine deficiency is real. While most of my colleagues have dismissed iodine deficiency as a relic of the early 20th century and third world countries, you can also find it in your neighborhood.
At prevailing pharmacy prices, one capsule of prescription Lovaza fish oil costs $4.33 each.
Yes, you heard right: $4.33 per capsule.
What do you get for $4.33 per capsule? By omega-3 fatty acid content, you get 842 mg EPA + DHA per capsule.
I can also go to Sam's Club and buy a bottle of their Triple-Strength fish oil with 900 mg omega-3 fatty acids per capsule at $18.99 per bottle of 180 capsules. That comes to 10.5 cents per capsule. That puts the price of fish oil from Sam's Club at 97.6% less cost compared to Lovaza for an equivalent quantity of omega-3 fatty acids.
What if we repriced Sam's Club's Triple-Strength and brought it "in line" with what we pay for Lovaza? That would put the value of one bottle of Sam's Club Triple-Strength fish oil at $780 per bottle.
If you have any doubts about the value of organic foods vs. conventionally-grown foods, then take a look at the findings from a USDA--Yes, USDA--sponsored study.
In this study, the nutritional content of organic vs. conventionally-grown blueberries were compared. Ironically, these observations come from the USDA's Genetic Improvement of Fruits and Vegetables Laboratory of the Produce Quality and Safety Laboratory.
Their findings (all values expressed as weight per 100 grams fresh weight blueberries, or a bit less than 1/4 cup):
Total phenol content (e.g, flavonoids):
Organic: 319.3 mg Conventional: 190.3 mg
Organic blueberries had 68% greater phenol content.
Total anthocyanins (an important class of flavonoids):
Organic: 131.2 mg Conventional: 82.4 mg
Organic blueberries had 59% greater anthocyanin content.
Antioxidant capacity (ORAC):
Organic: 46.14 mg Conventional: 30.8
Organic blueberries had 50% greater antioxidant capacity.
Flavonoids suspected to carry unusually potent health effects--malvidin, delphinidin, myricetin, and quercetin--were all contained in greater proportions in the organically-grown blueberries, also. These flavonoids are demonstrating pharmacologic-level health effects in preliminary studies.
Why a genetics laboratory? After all , the study findings came out heavily in favor of non-genetic, organic farming methods of growing produce. It certainly must have at least given pause to the vocal group within agriculture and the USDA that have long argued that organic produce is no different. I suspect that the laboratory will now try to recreate the nutritional value of organic through genetic manipulation of cultivars grown using conventional methods.
Regardless of the motivations behind the study, we see that there is no comparison: organic blueberries are superior in nutritional value to those grown with conventional pesticides and herbicides. While the study addressed only blueberries, the dramatic difference makes it likely that similar differences exist in other fruits and vegetables.

Men and women are advised to take calcium because it has been shown to reduce blood pressure modestly. Women, in particular, can stall the deterioration of bone strength (mineralization) by taking calcium supplements, 1200-1300 mg per day, and eating calcium-rich foods like dairy products.
Is that all true?
It is true insofar as we remain vitamin D deficient. A funny thing happens when you fully replete vitamin D: Intestinal absorption of calcium as much as quadruples. That means your body will efficiently absorb the calcium in broccoli and spinach.
Is it still necessary to force-feed your body megadoses of calcium once vitamin D has been repleted? I don’t think so.
While the evidence is indirect, several observations point towards the lack of necessity of calcium once vitamin D is addressed. For instance:
Women who take calcium, 1200 mg per day, with vitamin D, 800 units per day, double their five-year risk for heart attack, according to a New Zealand study.
Men who take calcium, 1200 mg per day, with vitamin D, 800 units per day, also may substantially increase heart attack risk.
Bone density increases more with vitamin D than with calcium. Calcium may not even be necessary to increase bone mineralization, since there are data to suggest that vitamin D can accomplish this by itself.
Calcium suppresses parathyroid hormone, PTH. That is, in fact, how calcium stalls (usually does not reverse) bone mineral loss-not by adding calcium to bone, but by suppressing PTH release. (PTH causes bone demineralization.) Vitamin D suppresses PTH to a far greater degree than calcium.
What is needed is a broad reconsideration of the advice everyone is getting to take calcium. In an age when more and more people are appreciating the power of vitamin D supplementation to achieve normal blood levels, there may be danger ahead for those who fail to address their calcium overdosing.
Why would vitamin D be prescribed when vitamin D3 is available over-the-counter?
Let's review the known differences between vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol):
--D3 is the human form; D2 is the non-human form found in plants.
--Dose for dose, D3 is more effective at raising blood levels of 25-hydroxy vitamin D than D2. It requires roughly twice to 250% of the dose of D2 to match that of D3 (Trang H et al 1998).
--D2 blood levels don't yield long-term sustained levels of 25-hydroxy vitamin D as does D3. When examined as a 28-day area under the curve (AUC--a superior measure of biologic exposure), D3 yields better than a 300% increased potency compared to D2. This means that it requires around 50,000 units D2 to match the effects of 15,000 units D3 (Armas LA et al 2004).
--D2 has lower binding affinity for vitamin D-binding protein, compared to D3
--Mitochondrial vitamin D 25-hydroxylase converts D3 to the 25-hydroxylated form five times more rapidly than D2.
--As we age, the ability to metabolize D2 is dramatically reduced, while D3 is not subject to this phenomenon (Harris SS et al 2002).
While there are dissenters on this view, the bulk of evidence suggests that D2 is an inferior form of D3.
Then why is D2 prescribed by many doctors when the natural, human, and superior D3 is available over-the-counter?
You already know the answer: Much of your doctor's education did not come from scientific lectures nor from reading scientific studies. It came from the pretty drug representative in the waiting room who hands the doctor reprints of the "studies" performed by the drug industry to support the use of their drugs. There is no such nutritional supplement representative in the waiting room. This preference for the "drug" D2 over the supplement D3 also stems from the inherent preference of physicians for things they can control, whether or not there is proof of superiority.
In my view, there is absolutely no reason to take vitamin D2 over D3 except to enrich the drug industry.
