D3 - cholecalciferol 5000iu 100 softgels - 125mcg | Jarrow Formulas
Jarrow Formulas Vitamin D3 5000iu (125mcg) with cholecalciferol is the most bioavailable form of vitamin D with a high potency and prolonged retention time. It is required for enhanced absorption and proper blood levels of calcium and phosphorous, promoting the health of bones, muscles, and other organs
who benefits from vitamin D3?
The World Health Organization (WHO) recommends a daily intake of 1000 iu or more for good health. The ones to benefit from this advice are typically men and women who have office jobs, men and women over 40, men and women with a darker skin of African Arabian or African descent, men and women with skin disorders caused by vitamin D deficiency. Optimal vitamin D levels are a must for a beautiful elastic skin, a good prostate function and strong and healthy bone structure. A low vitamin D status has also been linked to low testosterone levels and vice versa.
what distinguishes Vitamin D3?
• vitamin D3 (cholecalciferol) softgels
• low levels linked to poor heart health
• free of vitamin A
• important for bone health: osteocalcin synthesis & calcium absorption
how does the active ingredient function in this product?
Fat-soluble Vitamin D3 is converted by the kidneys into the hormone calcitriol, the active form of Vitamin D3, which affects a variety of target tissues, including bone, intestine, muscle, brain, skin and immune cells. Calcitriol enhances calcium and phosphorous absorption and stimulates the synthesis of osteocalcin, an important structural protein in bone. Also, calcitriol is involved in proper cell differentiation (changing of cell function), including in prostate cells.
Vitamin D is a fat soluble vitamin that is obtained from food, sun exposure, and dietary supplements. Once vitamin D is ingested or synthesized in the skin, it undergoes two hydroxylation reactions in the body, first in the liver to calcidiol (25-hydroxycholecalciferol), and then in the kidney to calcitriol (1, 25-dihydroxycholecalciferol).
Vitamin D is critical for healthy bone development, remodeling and maintenance. It is also known to play a key roll in the maintenance of many other organ functions.
Why vitamin D3?
Two forms of vitamin D, vitamin D2 (ergocalciferol) and D3 (cholecalciferol), are available in supplements and fortified foods. Although both forms can raise available vitamin D in the body, vitamin D3 produces three times the amount of available vitamin D metabolites with a longer retention time and higher activity potential.
Jarrow Formulas Vitamin D3 utilizes only cholecalciferol, the superior kind of vitamin D, to ensure the delivery of a high quality, more bioavailable form of vitamin D.
Vitamin D deficiency in the U.S.
Obtaining sufficient vitamin D from food and daily sun exposure can be difficult for many people. The US National Health and Nutrition Examination Surveys (NHANES) have reported that the average intake of vitamin D has been declining and that many children and adults in the United States are likely to be vitamin D deficient. This trend may be due to increased body mass index (BMI), reduced dairy consumption, lactose intolerance, milk allergy, increased use of sun protection, and vegetarianism.
In breast-fed infants, human milk alone is not sufficient to provide the required amount of vitamin D. The American Academy of Pediatrics (AAP) recommends vitamin D supplementation in both infants and mothers. Women and older individuals also tend to have vitamin D levels that are lower than recommended levels. In the population above age 50 in particular, this may be caused by a slowed or compromised metabolism and poor absorption of vitamin D.
Adequate vitamin D is essential for optimal health. Supplementation of vitamin D with Jarrow Formulas Vitamin D3 can contribute to the required daily vitamin D intake and thus promote healthy bones, skeletons, immune function, and cell protection in both the young and the old.
Vitamin D plays an important role in stimulating the absorption and maintenance of proper blood levels of calcium and phosphorous, critical minerals for bone development and preservation. Numerous studies have shown that vitamin D3 supplementation may support bone strength and reduce the risk of falls, fractures, and bone loss in elderly individuals, especially those with inadequate calcium and/or vitamin D intakes, postmenopausal conditions, and difficulty exercising. Vitamin D3 supplementation can support not only healthy bone development and growth in young children and adults, but also promote balanced remodeling and rebuilding of bones in a mature population
Cell growth and differentiation
Although a precise mechanism has not been elucidated, vitamin D has been shown to support balanced cellular growth and differentiation.
Vitamin D has an ability to modulate production and stability of proteins and associated factors that are critical for healthy cell proliferation, apoptosis, and differentiation. Additional pre-clinical and clinical studies are underway to discover further benefi ts of vitamin D in sustaining well-controlled cell function and growth.
Vitamin D has been shown to regulate both immune-promoting and immune-suppressing effects of immune cells and factors. Interactions among vitamin D receptors and other molecules on the immune cells enhance the communication between various signaling pathways, resulting in efficient and appropriate immune responses. In addition, this basic vitamin may play a signifi cant role in cardiovascular health by regulating blood pressure (through balanced hormone secretion), heart and vessel muscle function, and normal immune response. A growing body of research on vitamin D also suggestes benefits of this vitamin to normal mood and blood sugar regulation, and overall mortality and well-being, although additional studies are necessary for better understanding of the modes of action.
Some supplements are suitable for both men and women of all ages as well as children. But other supplements are specifically targeted to the aging woman or man. Another supplement is especially suitable for athletes, regardless of gender.

Influence of the moon on our behaviour
For the longest time, people have felt the influence of the (full) moon on their behaviour.
Especially on cloudless nights, many of us feel an urge to go outside and enjoy watching the full moon. Some will even go so far that they will go on a nightly hike or bike ride.
If this urge still persists today, how influential must the moon it have been in the past when we only could rely on light of the sun, moon and fire?
This is why so many people believe how lunar cycles can and do influence many other aspects of our behaviour and health.
The most persistent one is about its influence on menstruation cycles, fertility and even on the gender of babies. It's not too difficult to understand where this belief comes from: after all, a lunar cycle is almost as long as the average menstruation cycle.
However, until recently, scientists haven't been able to confirm most of the claims.
Only a short while ago it was confirmed how indeed, the full moon does have an impact on the length of our sleep. Even those who live in an urbanized environment, feel the effect of the full moon on their sleep cycle, even though it is far less pronounced than for indigenous people living without artificial light.
About time to explore whether the moon cycle really affects other aspects of our health and/or behaviour.
Feeling sad and stressed due to COVID-lockdown?
Depression in winter time is quite normal, because we aren't exposed to the vitamin D-generating sunrays, which also enhances immunity levels. Fortunately, we can take vitamin D supplements to combat seasonal depression as well as enhance immunity levels.
Another way to chase sadness away is by celebrating, no matter whether that's Sinterklaas, Winter Solstice, Hanukkah, Christmas or New Year. We will decorate our houses, exchange gifts and overeat , get a bit tipsy and enjoy ourselves.
This year is different: restaurants, shops and even gyms need to close down and we are not allowed to gather together in groups. Lack of entertainment, retail therapy and exercise will make it much more difficult to overcome feelings of depression.
It gets worse when you are among those who work in the tourism or entertainment industry and have lost your job as well as most of your income.
For now it is probably best to just accept the current state of affairs and try to console yourself with non-edible goods, such as nice music with a good book, entertaining movie, and aromatherapy (perfume/room fragrances).
And, weather permitting, put on your walking shoes and go for a long walk in the forests or local park.
But perhaps you have been feeling too stressed to enjoy whatever you still can do to relax? Or you were already feeling sad before COVID-19 came along? In that case, DHEA might help.
Can vitamin D help combat infectious diseases like COVID-19?
Are white teeth healthy? Advantages and disadvantages of dental veneersOver the past few weeks, people couldn't stop talking over how a couple of famous Dutch celebrities have undergone dental surgery procedures so they could flash a truly blinding white smile. For this to happen, dental surgeons file away part of the original teeth. Apparently this procedure is becoming ever more popular with the advent of social media like Instagram and YoutTube where these semi-celebs show off their health and wealth.
Yellow teeth are stronger!Gone are the days we were happy with our natural yellowish teeth. It seems that everyone strives for bright white teeth. There are whitening agents in toothpastes which apparently don’t really do the trick, floss, mouthwash, strips, gels, and even chewing gum. Yellow teeth seem to get a bad reputation and are usually associated with poor oral hygiene. Fortunately, we have some good news for those who lack those pearly whites. Yellow teeth are actually stronger than bright white teeth!
But rest assured, yellow teeth are mostly stronger than white teeth.
The strongest teeth are natural, healthy ones and these teeth are not white. At least, not white like the colour of paper, or even the colour of piano keys. They are a couple of shades darker than that. The enamel itself is a blueish white colour, but it is also somewhat translucent so the yellow of the dentine beneath it shows through to make the overall colour of the teeth either light grey or light yellow.
Low-dose radiation therapyLast week I listened to a Dutch podcast, which in general discusses news and politics, but for once, talked about low-dose radiatian therapy as a way to treat COVID-19. This made me curious enough that I wanted to find out more about this particular treatment method.
Most of us know at least one person, whos's been treated with high-dose radiation order to get rid of a malignant tumor. It is less well known that low dosages can be used as well and is used in some countries to treat inflammation disorders such as arthritis.
In general, this is met with disbelief as the official point of view is "all radiation is harmful" .
Proof to the contrary
Yet, over 3000 scientific research papers show that low dose irradiation is stimulatory and/or beneficial in a wide variety of microbes, plants, invertebrates, and vertebrates.
Vitamin K and heart healthExperts are recommending that people do what they can to boost their immune systems to work on their immunity and strengthen their defense mechanisms to better combat infection and spread of this virus.
According to a recent study conducted in partnership with the Cardiovascular Research Institute Maastricht, foods rich in vitamin K have been helpful in the battle, and a deficiency may worsen the symptoms of COVID-19.
This virus is known to cause degradation of elastic fibers in the lungs as well as blood clots, vitamin K has been shown to be helpful in the production of proteins that regulate clotting. As such experts have linked the consumption of foods that are rich in vitamin K to blood vessels, bones, and the lungs.
Zinc and HCQ
In the past few months, nearly everyone will have become familiar with the malaria drug hydroxychloroquine (HCQ) and how it has been welcomed as a miracle drug, only to be set aside as being too dangerous to expose sick patients with underlying cardiovascular diseases to it.
Upon learning how HCQ is supposed to be used in this crisis, I was flabbergasted to read how HCQ was put to use by itself, as a drug on its own. True enough, HCQ is a malaria drug, but it was not just meant to be used as a curative medicin on its own for COVID-19 but as a messenger to transport the true miracle mineral, zinc into cells.
The now famous Zelenko protocol which uses HCQ , azithromycin and zinc as well as a number of other essential vitamins and minerals, was never meant to be used in hospital either, but for use by doctors on patients who had just fallen ill.
Now the researchers who discredited HCQ in the Lancet article have been debunked as having used fraudulous data in order to promote a much more expensive drug in which one of the authors had a vested interested, we think it is about time to explain a thing or two on why and how HCQ is used in combination with zinc.
How to prevent getting sick from the flu
You can prevent germs from making you ill in two ways: prevent entry into the body by careful hygiene, and if they do get in, make sure your body’s natural immune system is able to fight these germs, so they self-destruct before overwhelming the system.
Most flu germs are spread in two ways:
- touching such as hand-to-hand contact
- droplet spread when germs ride along on tiny water droplets that are sneezed or coughed into the air
Try these flu prevention tips to avoid person-to-person spread:
- avoid shaking hands, but bow or give a head nod
- avoid nose-picking as the nose is a breeding ground for germs
- sneeze into a disposable handkerchief and if you don't have one available, sneeze inside your elbow
- shun coughers and sneezers as much as possible.
- avoid crowded rooms
Pigmentation spots : why do we get them when we age?Do you sometimes look down onto your arms and notice they are covered with white spots that resemble freckles in reverse?
Especially when arms get tanned in summer, these white spots tend to stand out more than ever.
This led me to the idea to look up what can be a cause of this weird pigmentation.
Mine turns out to be one called idiopathic guttate hypomelanosis (IGH), in other words, an unexplained teardrop-shaped lack of pigmentation, which is apparently very common among most people of over 40 years , but may also happen at a younger age. These white spots appear on the shins, legs, arms, and other sun-exposed areas of the body like the face, neck, and shoulders.
Apparently the body experiences a gradual reduction of melanoyctes and skin cells no longer produce pigment, a similar process that causes the graying of hair. The condition is also increasingly being seen in both sexes and darker skinned individuals with a history of long-term sun exposure, which has lead scientists to believe that excessive sun exposure and sun damage is another cause of these white spots.
They are generally 1 to 3 mm in size and commonly show up on the legs before progressing to other parts of the body.
These white spots are not caused by trauma or infection, nor do they indicate an increased risk of skin cancer.
Hereditary factors may be involved because this skin problem seems to run in families.
IGH is not related to vitiligo, in which melanin-producing cells called melanocytes die or are unable to function properly and no longer form melanin.
Other common causes of skin discolorations are
