Zinc And Thyroid Function

For years, mariners have depended on sacrificial anodes as a means to counter corrosion. Zinc anodes have ranked as the most popular ones in this category. Typically, an anode will corrode as it protects another metal that is lower than itself in the galvanic series of metals and alloys. This will continue as long as both form a part of an electrical circuit. That s the reason these anodes are referred to as sacrificial anodes. They can be attached to your boat s underwater metals and they start working at once. It is important to install sacrificial anodes in order to keep your other expensive boat metals from corroding in water.While purchasing zinc anodes (also known as boat zincs), do remember to check if they conform to MIL-A-18001 standards. Such anodes comprise 99% zinc and the remaining balance comprises of very minute quantities of metals such as lead, iron, cadmium, aluminum and copper. It needs to be noted here that anodes are essentially a disposable piece of metal. Once they are eaten up by the effects of corrosion, they need to be disposed off and replaced with new anodes. This ensures that your corrosion protection cycle continues as intended and your marine vessels are protected for years to come. How do sacrificial anodes work?If two dissimilar metals (such as a stainless steel drive and bronze propeller) come into contact underwater a constantly occurring stream of electricity passes from one metal to another through water. Subsequently, the metal that is more active among the two will corrode first. Thus, when you install a sacrificial anode to the hull or propeller, the anode is the active metal in this circuit and hence it corrodes before your expensive boat metals. However, it must be noted that once the anode reaches around half of its original size or dimensions, it needs to be replaced with a fresh anode to keep the corrosion cycle on.For a long time, zinc anodes have been the most popular ones. But in the recent past, magnesium and aluminum anodes have also been much preferred. To know more about which type of anodes you should install, it is advisable to take the professional opinion of an anode dealer, marine electrician or boat manufacturer.Following are some quick pointers to help you know which anodes suit different water applications: Salt water: Zinc and aluminum anodes are the best options for sea water applications. It is advisable to use these anodes along with a galvanic isolator to control the rapid consumption rate of anodes. Brackish water: This comprises a mixture of salt and sea water. In such conditions as well, zinc anodes or aluminum anodes are used. As the water starts getting slightly fresh, the amount of electrical current that passes between two metals is less. In this case, aluminum anodes should be used because they are more active. Fresh water: Only magnesium anodes should be used for fresh water applications.

Frequently Asked Questions

    For women: how do i naturally balance or cure hormone imbalance?
    I am 25.. I feel that i have had a hormonal imbalance since i started puberty.. It got mistaken for years as a chemical imbalance and i was prescribed to horrible horrible medication from anti depressants to anti psychotics that did nothing but make things much much worse. I recently had my hormones tested and 3 major ones were off balance. I had high testosterone (which explains my moodiness and unwanted hair) and low thyroid function.. I forgot the other.. I am scared and extremely unhappy. Right now I am getting acupuncture but of course it hasn't worked quite yet.. I feel a little bit better but i'm hoping that someone with knowledge of this can help point me in the right direction.. One thing did help for me for a short time but it is no longer working :( When I first started the nuva ring i felt AMAZING!!! It worked for months, and i can't tell you how great it was.. I am still on it, but for some reason it is no longer working for me.. I just want to feel good again.. My hormone imbalance has effected every aspect of my life.. It is hard to lose weight, I have no energy, I have extreme unpleasant moodiness and thoughts.. I have unwanted hair everywhere.. It's even hard to get out of bed in the morning.. I feel horrible about myself.. All I want is to feel good. I'm continuing acupuncture, and taking a chinese herb vitamin called gentiana complex, and it has started helping in some ways.. Please if you have ANY information.. I would love to hear your responses. Thank you.

    • ANSWER:
      Sounds like you have PCOS & hypothyroidism & probably vitD deficiency.

      Are you taking thyroid hormones - most folks recommend a natural thyroid hormone (like Armour) over synthetic hormones.

      I believe symptoms can be managed & alleviated if you bring your body back to a state of balance with proper low carb diet & careful monitoring of everything you put in your mouth (including fluoridated water, drugs, toothpaste with fluoride, etc.).

      I suggest -

      1. optimizing vit.D levels with a *minimum* of 10,000iu per day to the highest level of normal >80 ng/ml (200 nmol/L),
      2. Take vitD test to see if you are deficient & require higher supplementation
      3. If you are using artificial sweeteners or foods with chemicals - stop immediately
      4. Optimize thyroid function
      5. consider getting a fluoride filter for your water - I recommend reverse osmosis or Berkey but Zerowater will do also
      6. researching iodine supplementation - adding seaweed, especially kelp to the diet
      7. immediately starting Atkins low carb way of eating to normalize blood sugar, insulin & other hormones (discuss with doctor lowering or eliminating any meds for blood sugar, blood pressure or cholesterol - doing these with low carb will lower levels dangerously so)

      People think low carb is for weight loss when it's actually for normalizing hormones & bringing the body to a state of homeostasis (being normal) & is just as good for the underweight. A normally functioning body does not go into the disease state & excess fat storage. The body is a self healing unit if provided proper nutrition.

      Carbohydrates greater than 9grams per hour trigger insulin. Insulin is considered the "bully" hormone - when it dominates the bloodstream, it does not allow other hormones to fully function


      They don't know if insulin resistance creates PCOS or if PCOS creates insulin resistance. I believe it's just another side effect of insulin dysfunction. Long term ingestion of refined carbs "burn out" the insulin receptors on muscle cells, so calories go directly to fat cells, leaving muscle cells screaming for nutrition.

      Most people get overweight because their bodies just can't process carbs any more. They become insulin resistant & carbs go straight to fat cells. Fat storage is a symptom of the disease state. When your muscles become insulin resistant, then calories go directly to fat cells instead of to glycogen stores & you become overweight fast. It's nearly impossible to lose weight at this point without minimizing carbs because the body no longer is able to process carbs. The body won't release fat stores until the blood stream is free of insulin. In someone insulin resistant, the insulin response is too sensitive & produces too much insulin.

      I highly recommend 1 oz. (about 4) canned (or fresh) oysters every day for the naturally occurring zinc (170% DV) & 90% DV of vitamin B12 as well as getting 1g a week in Omega 3 fatty acids, EPA/DHA. Animal studies show that zinc deficiency is associated with decreased serum T3 levels. Zinc may play a role in thyroid hormone metabolism in patients with low T3 and may contribute to conversion of T4 to T3 in humans.

      I recommend optimizing vit.D levels & starting a low carb lifeplan.

      PCOS forum -


      Vitamin D deficiency may contribute to the wide set of disorders associated with metabolic syndrome (syndrome X), as well as to PCOS. In a study published in 2004, the authors saw a 60% improvement in insulin sensitivity in healthy, vitamin D replete adults

      Symptoms of acute vitD deficiency can include -

      Hair Loss
      Weakness, Sadness, Listlessness, Tiredness, Muscle-Pain,
      Circulation problems,
      Twitching, (Eyelid, Arm, or Legs)
      fingernails have small white spots,
      Standing causes back, hip, groin, and/or leg pain.

      83% of people with low back pain were vitamin D deficient
      95% of people with chronic pain had the pain go away with vitamin D

      My theory is that since vitD is a mucolytic agent, it keeps lymph fluid thin & flowing. When the lymph fluids get thick &the fluids pool around nerves putting pressure on the nerves & triggering pain. Lymph fluids have no "pump" like the heart & works on gravity & movement to flow & fluids drain away relieving pressure on the nerves.

    How does one get hypo thyroid and are there any natural CURES?
    I know someone who was diagnosed with hypo thyroid. Of course she was given a prescription for the diagnosis, but she wants some natural cures. Any ideas?

    • ANSWER:
      Hi Raynpetal

      Here are some ideas to heal your friends condition. Also be sure to do colon and liver cleanse to clean out the toxins in the blood.

      Cause: Hypothyroidism can be caused by food allergies, excess stress, environmental toxins, insufficient exercise, B vitamin deficiencies, lack of iron, lack of digestive enzymes, liver disease, hormone imbalances, and/or parasites. All of these factors need to be screened for and addressed before lasting relief can be achieved.

      Sulfa drugs, lithium, synthetic estrogen, and antihistamines can exacerbate hypothyroidism symptoms. In addition, if you are on thyroid medication, increase calcium supplementation to reduce the risk of bone loss.

      Low thyroid function may also be due to Hashimoto`s disease, a condition in which the body becomes allergic to its own thyroid gland and forms antibodies that attack it, thus lowering thyroid hormone output.


      Natural Cures

      Diet: Eat an organic, whole foods diet, emphasizing foods that are naturally high in iodine such as fish, kelp, vegetables, and root vegetables (such as potatoes). Also, increase your daily consumption of foods rich in vitamin B complex, such as whole grains and raw nuts and seeds, and foods rich in vitamin A, such as dark green and yellow vegetables. But avoid foods that slow down production of thyroid hormone, such as cabbage, Brussels sprouts, mustard greens, broccoli, turnips, kale, spinach, peaches, and pears.

      Herbs: Mild cases of hypothyroidism can be helped by herbal bitters such as gentian or mugwort, while constipation due to low thyroid function can be improved by yellowdock, butternut, or cascara sagrada. St. John`s wort can also be helpful.

      Homeopathy: Calc carb. in a dose of 1M once a day is very useful for treating hypothyroidism and improving overall thyroid function.

      Hydrotherapy: Hydrotherapy is the application of water, ice, steam and hot and cold temperatures to maintain and restore health. Treatments include full body immersion, steam baths, saunas, sitz baths, colonic irrigation and the application of hot and/or cold compresses. Hydrotherapy is effective for treating a wide range of conditions and can easily be used in the home as part of a self-care program. Many Naturopathic Physicians, Physical Therapists and Day Spas use Hydrotherapy as part of treatment. I suggest several at-home hydrotherapy treatments.

      Lifestyle: Regular aerobic exercise can play an important role in helping to regulate thyroid hormone production.

      Nutritional Supplementation: Organic thyroid glandular extracts can help restore normal thyroid function, but should only be used under the supervision of your physician. Other useful nutrients include vitamin A, vitamin B complex, essential fatty acids, iodine, kelp, calcium, magnesium, and zinc.

      Alternative Professional Care: If your symptoms persist despite the above measures, seek the help of a qualified health professional. The following professional care therapies have all been shown to be useful for treating hypothyroidism include: Acupuncture, Biofeedback Training, Cell Therapy, Detoxification Therapy, Environmental Medicine, Homeopathy, Magnetic Field Therapy, Naturopathic Medicine, Osteopathy, Qigong, Traditional Chinese Medicine and Yoga.

      Best of health to both of you

    What can i do to boost the effects of my thyroid? And its metaolism boosting ability?
    Actually, i want to know anything that boosts my metabolism as much as i possibly can. And i know that the thyroid boosts metabolism. So what can i do to boost the effect of my thyroid or anything else that boosts metabolism.

    • ANSWER:
      to support thyroid gland functions, you'll need vitamins and minerals.

      First of all, you need a good source of iodine to help your thyroid gland make the hormones.

      Most of us get enough iodine through salt table (iodized salt), but most of us don't know that our thyroid gland can be a little slow ! Look into eating more fresh seafood also.

      More foods containing iodine :

      * carrots
      * kelp
      * fruits
      * nuts
      * rice
      * flaxseed oil
      * linseed oil

      and also support your adrenal function to process the iodine with

      * vitamin C
      * Zinc
      * Selenium
      * vitamin B

      a good thyroid supplement can take care of that

      and also :

      * coffee
      * ginger
      * cinnamon

    Does anyone know any vitamins or natural apart from exercise to increase the efficiency of the thyroid gland?
    Does anyone know any vitamins or natural apart from exercise to increase the efficiency of the thyroid gland?
    My cousin has a thyroid issue and was wondering if anyone knew any vitamins or natural herbs apart from exercise and prescribed medications tht would help?

    • ANSWER:

      * An all-purpose mineral supplement from a health food store,
      * Ascorbic acid (C),
      * Choline.
      * Copper is necessary for the production of the TSH.
      * Copper and Zinc for the peripheral cellular mechanism of T4.
      * Iodine; 100 to 180 mcg per day is the suggested dose.
      * Kelp,
      * Thiamine (B1),
      * Vitamin B complex,
      * Zinc.

      2) AVOID CERTAIN FOODS: The following foods, if eaten frequently, could interfere with iodine uptake, and cause poor thyroid function:

      * Almonds have a suppressive effect.
      * Broccoli,
      * Brussels sprouts,
      * Cabbage,
      * Cashews have a suppressive effect,
      * Cauliflower,
      * Garden cress could do the same,
      * Kale,
      * Kohlrabi,
      * Milk of cows grazing on these foods,
      * Mustard -- brown/Indian, black, or white,
      * Nitrates interfere with the tyrosine-iodine linkage.
      * Peanuts are OK; only the SKINS of peanuts need to be avoided.
      * Radish,
      * Rapeseed,
      * Rutabaga,
      * Soybeans, and
      * Turnips.

    is there any natural remedies to help a slow thyroid?
    I exercise 5-6 days a week, eat a bundle of vegies,meat and little carbs.Meanwhile my energy is decreasing and I cant seem to tone up. Is there any natural solutions to a slow thyroid?

    • ANSWER:
      Yes definately.
      Iodine and tyrosine are essential # nutrients required for the production of thyroid hormones.
      Selenium is required for the conversion of thyroxine (T4) to triiodothyronine (T3)
      Zinc is involved in the transcription of thyroid hormone and as an enzyme co-factor in T4 to T3 conversion.
      Vitamin A is involved in the formation of thyroid hormone receptors, and in the binding of thyroid hormones to cellular receptors.
      As an electron donor, vitamin C is involved in tyrosine metabolism and thyroid hormone synthesis.
      Vitamin D is required for the maintenance of a normal healthy immune system and healthy cell development.
      Cysteine, methionine and taurine which help support Phase II liver detoxification pathways.
      Bupleurum falcatum has been traditionally used to aid in the maintenance of healthy liver metabolism and provide support for healthy liver function.
      Antioxidants zinc, selenium, vitamin C and vitamin E that help reduce the harmful effects of free radicals.

      Also, there are certain foods that actually suppress thyroid function.
      Goitrogens can induce hypothyroidism and goiter. In sufferers of hypothyroidism, goitrogens can further depress thyroidal function and stimulate the growth of the thyroid (goiter).
      Many goitrogens are generally members of the brassica family. These include:
      Brussel Sprouts
      Rape seed (Canola Oil)
      Other goitrogens include:
      Pine nuts

      Also, avoiding dairy and gluten products is ideal as there is a high connection to autoimmune disorders and gluten intolerance, same with dairy, and also flouride.
      Flouride suppresses the thyroid hormone. Infact it was used by doctors till the 70s for overactive thyroids!
      But before you jump to conclusions that its your thyroid, go get your TSH levels checked by your doctor. Its a simple blood test, and for peace of mind, its always good to have a definate diagnosis.
