The cost is a whopping $150.80 average retail cost for a month supply with a dose of 2-grams daily (double that for the recommended 4-grams per day regiment). Consider similar pharmaceutical grade fish-oil n-3FA products such as Vita Sanus Opti-EFA where a 2-gram/d regiment would only cost $39.00/month.
From the Lovaza Site http://www.lovaza.com/benefits-of-lovaza/prescription.html :
- LOVAZA uses a 5-step purification process that helps remove mercury and other environmental toxins that can be present in fish oil and ensures reliable concentration of EPA and DHA in every capsule
- The FDA-approved dose of LOVAZA is 4 capsules per day. It could take up to 14 capsules per day of an omega-3 supplement to provide the same amount of EPA and DHA found in 4 capsules of LOVAZA
By definition pharmaceutical grade:
Pharmaceutical grade fish oil has the following characteristics:
|•||Concentration of EPA and DHA > 60%|
|•||Ratio of EPA/AA > 25:1|
|•||Concentration of PCBs <>|
Furthermore given that Lovaza advertises that one gram (one gel cap) has 1 gram of n-3FA and 465 mg of EPA and 375 mg of DHA, the VS Opti-EFA trumps its EFA & DHA content with an equivalent one gram (2-gel caps) equivalent dose having 600 mg of EPA and 400 mg of DHA. All at a much more comfortable cost. You will spend over $150/month for Lovaza when you can spend under $40/month for Opti-EFA or similar brands and get a bigger bang for your buck on DHA/EPA content. Do the math, it is a no brainer.

Is it safe for patients taking thyroxine to have a low but not suppressed serum TSH concentration?
Graham Leese & Robert Flynn
University of Dundee, Tayside, UK.
For patients taking thyroxine replacement guidelines generally recommend aiming for a target TSH within the laboratory reference range. The evidence for this guidance is generally based on an extrapolation of data from patients with endogenous subclinical thyroid disease. We aimed to examine the safety of having a TSH which was either suppressed (≤0.03 mU/l), low (0.04–0.4 mU/l), ‘normal’ (0.4–4.0 mU/l) or raised (>4.0 mU/l) in a population-based cohort of patients all of whom were treated with thyroxine.
We used a population-based thyroid register (TEARS) linked to outcomes data from hospitalisation records, death certification data and other datasets between 1993 and 2001. The endpoints of cardiovascular disease, dysrhythmias and fractures were assessed. Patients were categorised, using a time weighted mean of all TSH recordings.
There were a total of 16 426 patients on thyroxine replacement (86% female, mean age 60 years) with a total follow-up of 74 586 years. Cardiovascular disease, dysrhythmias and fractures were increased in patients with a high TSH (adjusted hazards ratio 1.95 (1.73–2.21), 1.80 (1.33–2.44) and 1.83 (1.41–2.37) respectively), and patients with a suppressed TSH (1.37 (1.17–1.6), 1.6 (1.1–2.33) and 2.02 (1.55–2.62) respectively), when compared to patients with a TSH in the laboratory reference range. Patients with a low TSH did not have an increased risk of any of these outcomes (HR: 1.1 (0.99–1.123), 1.13 (0.88–1.47) and 1.13 (0.92–1.39) respectively.
People on long-term thyroxine with a high or suppressed TSH are at increased risk of cardiovascular disease, dysrhythmias and fractures. People with a low but not suppressed TSH did not have an increased risk of these outcomes in this study. It may be safe for patients treated with thyroxine to have a low but not suppressed serum TSH concentration.

A thousand years ago, chia was prized by the ancient Aztecs as a food for energy, endurance, strength and good health. For many generations, natives of the southwestern deserts of what is now part of the United States depended on wild chia seed as a staple food and a source of remedies. According to a book by James Scheer (a nutritionist/writer), historian Harrison Doyle, who, in the early 20th century lived with various tribes in the Americas, wrote that "it was nothing for tribesmen to run for 24 hours on a tablespoon of chia seed and a gourd of water." Unfortunately, is really nothing more than testimonial and anecdotal evidence to date on chia and stamina. More research is required. The real research findings are with adaptogen and other eastern and western herbs. While chia has the potential, more research (double blinded studies) are needed to "prove" its worth in stamina and endurance and fatigue fighting properties.
I have researched and formulated two products for a niche market (Mixed Martial Arts fighters). It was developed as a me-too supplement already in use by endurance cyclists but with a focus on MMA and a very unique formulation never before seen on the market. Besides strength, these fighters rely on endurance, to outlast their opponents should a match go beyond 2 rounds. I developed two products one called CardioFactor and the other PreFight. Both products were very well researched with quite a substantial backing of evidence via scientific study and not just "hear say" or subjective testimonials.
If you are interested in learning more, the products are manufactured in the USA by AdapTx Labs and can be purchased online. I will disclose that my financial interest with this product was in the research and formulation of these products. https://www.adaptxlabs.com for more information.

Niacin may be one of the most potent agents out there for elevating HDL-C. However, once myocardial muscle (heart muscle) is damaged it goes through changes as all damaged tissue does, resulting in fibrosis and loss of elasticity, etc. and this cannot be reversed. Once heart muscle is damaged it cannot be repaired, hence the formation of scar tissue which hinders wall motion (as seen on ECHO) and in severe cases aneurysm formation. Prevention by plaque formation, stabilization of plaques, and reduction with the use of natural or synthetic statins (extract of fermented yeast of red rice or pravostatin for example) to reduce LDL-C is proven effective.
Raising HDL-C as a scavenger lipid is also proven and may be more beneficial to lowering LDL-C. If an ECG shows myocardial damage then it is wise to see a cardiologist to be studied further (Cath, ECHO, stress test) to determine the extent of you Coronary Artery Disease (CAD), as lipids are only one risk factor. You may have small coronaries, stable and/or unstable plaque formation (genetically predisposed), or other processes (hypercoagulable state) that may need specific attention and therapeutics. I recommend a daily dose of Aspirin (ASA 81mg) to all my patients over 45 if they are able to tolerate. For more on CADz, read my blog at www.DocSaleeby.blogspot.com
In good health,

Researchers have identified that the isoflavones in soy act as potent anti-thyroid agents, and are capable of suppressing thyroid function, and causing or worsening hypothyroidism. Soy is a phytoestrogen, and therefore acts in the body much like a hormone, no surprise that it interacts with the balance of the thyroid's hormonal systems. High consumption of soy products (either by high dose soy supplements or a high concentration of soy and soy-products) in our diet can be detrimental. Very high doses have been proven to cause goiter. I would suggest limits on soy and soy-based foods. In adults, just 30 mg of soy isoflavones per day is the amount found to have a negative impact on thyroid function. This amount of soy isoflavones is found in just 5-8 ounces of soy milk, or 1.5 ounces of miso. So use these products sparingly and definitely NOT daily.
Of course Iodine is very important to thyroid function. Low iodine intake can cause goiter and low thyroid hormones, but in America we have iodinated (iodized) salt to help obliterate this cause of hypothyroid. Make sure you use occasional iodinated salt in you cooking (most processed foods with salt in them don't use iodinated salt). And also a good source of Iodine is sea food (cod, sea bass and shellfish). Kelp is a vegetarian source of iodine.
Additionally, the lauric acid in coconut oil has a stimulant affect on thyroid function. This was discovered in the 1940's, so using coconut oil in your cooking or taking it as a daily supplement may help stimulate higher levels of T4 and T3 naturally.
With fluoridation of water (and fluoride toothpaste) we can see an impact on iodine. Fluoride displaces iodine in the body, so intake of iodine (by iod. salt and seafood) is important to counter the unavoidable fluoridation of municipal water systems and toothpaste.
Some herbals that have a history of increasing thyroid function are: bladderwrack, iceland moss, oat straw, saw palmetto berries, calamus root. There are preparations out there that have these as single or grouped supplements for thyroid health.
A 1/4 teaspoon of iodized table salt provides 95 micrograms of iodine. A 6-ounce portion of ocean fish provides 650 micrograms of iodine. Most people are able to meet the daily recommendations by eating seafood, iodized salt, and plants grown in iodine-rich soil. Recommendations for females age 14 and older: 150 mcg/day of iodine.
