Properties of Vitamin D as Per Research:
- Produced naturally in the body in a reaction catalyzed by the sun's UV light. But because sunscreen is a must these days, the effective amount UV light for conversion is significantly decreased.
- Vitamin D must, therefore, be supplemented.
- Helps prevent and aid the treatment of breast cancer, colon cancer, prostate cancer, heart disease, depression, weight gain, COVID-19, and other maladies.
- Modulates the immune system and facilitates the maturation of white blood cells.
- Deficiency also results in soft bones in children and fragile bones in adults (osteomalacia/osteoporosis).
Why Vitamin D?
Vitamin D is so crucial that our bodies convert it to its potent active forn (D3) after skin exposure to sufficient sunlight. But this is a problem for people in northern climates. In the U.S., for example, only people who live south of Los Angeles up to Columbia, S.C., get enough sunlight for vitamin D3 production throughout the year. Because of the effects of pollution and other ecological damages to the environment, the ability of the atmosphere to filter out ultraviolet radiation, mainly through the ozone layer, has been severely compromised. As such, it is now recommended that we all wear sunscreen at most times of the day when exposed to the sun, which leads to an even higher incidence of vitamin D deficiency no matter where we live.
Vitamin D deficiency has been linked to breast cancer, colon cancer, prostate cancer, heart disease, depression, weight gain, and other maladies. Studies show that people with higher levels of vitamin D have a lower risk of these diseases. It is now estimated that most Americans are Vitamin D deficient. Because dark skin absorbs less sunlight when compared to light-skinned people, vitamin D deficiency is even higher in dark-skinned Latinos, African-Americans, and others. The most substantial proven benefit of vitamin D is in helping calcium build strong bones. Along with calcium, regular exercise, and a healthy diet, Vitamin D is essential in the prevention and treatment of osteoporosis.
Why Vit K 1 & 2:
Vitamin K is essential because it is involved in blood clotting. It is required to make proteins for bone, cartilage, and blood vessel health. Vitamin K is vital to keep tissues from calcifying, that is, from stiffing our arteries. New research has highlighted how vital VIT K is to optimal health. A recently published Analysis in The American Journal of Clinical Nutrition concluded that adults, especially those 60 and above, with low blood levels of vitamin K had a 19 percent higher risk of dying early from any cause. Low vitamin K has been linked to arterial calcification, also known as calcium buildup in the arteries. Atherosclerosis happens when Calcium builds up in the coronary arteries. This buildup can also occur in arteries throughout the body, causing arterial stiffening, which leads to increase risk of mortality."
There are two main types of vitamin K1 and K2. K1 is mostly found in dark green vegetables, whereas K2 (which comprises several forms) is found in animal products, such as egg yolks, beef, and fermented foods. K2 is also produced by the healthy bacteria in our gut.

Vitamin D FAQs
- What does vitamin D do?
Getting enough vitamin D is essential to keep your body healthy. Vitamin D helps build strong bones that protect you from various health conditions, such as rickets. Rickets produces soft, weak bones in children. Weak bones in adults can lead to osteoporosis and osteomalacia.
Vitamin D may prevent certain types of cancer. Vitamin D deficiency can cause pain, fatigue, muscle weakness, and depression. Look to certain foods, supplements, and regular exposure to sunlight to get enough vitamin D.
With adequate calcium in the diet and active vitamin D, dietary calcium is absorbed throughout the body. However, if calcium intake is inadequate or vitamin D is low, the parathyroid glands will withdraw calcium from the skeleton to keep calcium in the blood within the normal range.
- How much vitamin D do you need and are you getting enough?
The National Institutes of Health (NIH) recommends an average daily intake of 400–800 IU, or 10–20 mcg.
However, some studies found that your daily intake should be higher if you have darker skin tones or aren’t exposed to the sun.
One study showed that a daily intake of 1,120–1,680 IU was needed to maintain adequate blood levels.
Also in this study, people who were deficient in vitamin D required 5,000 IU to reach sufficient blood levels.
Another study revealed that postmenopausal women needed 800–2,000 IU to attain adequate blood levels.
People who are obese or overweight may also need higher amounts of vitamin D.
All things considered, a daily vitamin D intake of 1,000–4,000 IU or 25–100 mcg should be enough to ensure optimal blood levels in most people.
According to the National Institutes of Health, the safe upper limit is 4,000 IU.
- Vitamin K1 vs K2: What’s the difference?
Vitamin K is a group of fat-soluble vitamins with a common chemical structure. They are stored in the liver and fatty tissue. The two types of vitamin K that are most commonly found in our diets are vitamin K1 (also known as phylloquinone or phytonadione) and vitamin K2 (also known as menaquinones).
Vitamin K1 is found primarily in leafy green vegetables, while vitamin K2 is mostly found in certain animal products such as cheese and yogurt, and fermented foods like sauerkraut.
Our bodies absorb Vitamin K2 than vitamin K1. Some forms of vitamin K2 stay in the bloodstream longer than vitamin K1. These factors may cause vitamins K1 and K2 to have different effects on your health.
Signs of vitamin K deficiency in adults can include easy bruising, excessive bleeding from a wound or injection site, or heavy menstrual bleeding.
- Do you need sunlight to process vitamin D?
Our bodies create vitamin D from sunlight on the skin of our uncovered arms, hands, and legs when we’re outside.
Most people will make enough vitamin D from being out in the sun for short periods from late March or early April through the end of September, particularly from 11 am to 3 pm. From October to March, the sunlight doesn’t contain enough UVB radiation for us to make vitamin D, so getting enough vitamin D from food and supplements is necessary.
The exact amount of time needed in the sun to make vitamin D is unclear for several reasons, but includes the color of your skin and how much skin is exposed. People with dark skin will need to spend more time in the sun to produce the same amount of vitamin D as people with light skin.
- What are the best sources of vitamin D?
- Wild salmon has around 988 IU of vitamin D, while farmed salmon has 250 IU per serving. Respectively, that’s 124% and 32% of the daily value (DV).
- Herring has 216 IU of vitamin D per serving. Other fatty fish like halibut and mackerel are good sources of vitamin D as well.
- Cod liver oil has 448 IU of vitamin D per teaspoon or 56% of the DV.
- Canned tuna has 268 IU of vitamin D per serving.
- Eggs from commercial hens have about 37 IU of vitamin D per yolk, while eggs from hens raised outside or fed enriched feed have higher levels.
- Wild mushrooms or mushrooms illuminated with UV light are high in vitamin D.
- Cow’s milk, soy milk, orange juice, and cereals including oatmeal fortified with vitamin D are other good sources of vitamin D.
- Is Vitamin D harmful without vitamin K?
Evidence seems to support this idea:
- Vitamin D toxicity causes hypercalcemia or high blood calcium levels.
- Hypercalcemia leads to blood vessel calcification (BVC).
- BVC is associated with heart disease.
- Vitamin K deficiency is associated with BVC.
- High vitamin K intake prevented BVC in animal studies.
- Vitamin K supplements may reduce BVC in humans.
- High vitamin K intake may reduce the risk of heart disease.
Although this may seem supportive, there is still no clinical evidence to prove that moderate amounts of vitamin D are harmful without a sufficient intake of vitamin K.
The science remains unclear whether high vitamin D intake is harmful if vitamin K intake is insufficient. Evidence suggests it could be a concern, but a definite conclusion has not been reached.
