Natural Factors Vitamin D3 Drops 1000 IU

Health begins with good nutrition. Different studies have demonstrated that vitamin D plays a vital role in bone health and immune function. Natural Factors Vitamin D3 provides 1000 IU of the natural form of vitamin D essential for the absorption of calcium and phosphorus. It is a potent liquid supplement carefully blended with medium-chain triglyceride (MCT) and flaxseed oils. Vitamin D is essential for the regulation of the calcium and phosphate balance in our bodies. The body makes vitamin D when it is exposed to sunlight. The body also recycles and stores the vitamin D it makes from sunlight. While we cannot make more vitamin D than we use, we can consume increased amounts of this essential nutrient through foods and nutrition supplements. It also helps maintain normal bone health and immune function and promotes healthy cell growth.

Vitamin D3 helps with the absorption and utilization of calcium

There are many ways to obtain vitamin D3 in your diets, such as through milk and salmon, but these foods do not always provide enough for you to maintain bone health. Your body needs to have the right amount of vitamin D3 to have strong bones. In one study, approximately 45~60% of people do not meet the recommended daily intake for vitamin D3.  This is why many people do not get enough vitamin D3 in their diet, which can lead to bone deficiency and bone disease.

Vitamin D3 helps with the maintenance and development of bones and teeth

Without it, multiple disorders can begin to develop. Vitamin D3 gets converted into a hormone called 1,25-dihydroxy vitamin D3, which stimulates calcium absorption from the intestine so the body can utilize it. The 1,25-dihydroxy vitamin D3 also causes osteoclasts to break down bone so new bone tissue can be created. People who have a deficiency in their vitamin D3 levels have a higher risk of getting a bone disease called rickets, which causes the bones to become soft and weak.

There are multiple ways that vitamin D3 can help you maintain healthy bones

For example, in one study with older women, when they took 300 IU/day of vitamin D3 for 3 months, this increased 1.5% in their lumbar spine bone mineral density (BMD). In another study, when adults with diabetes were given 600 IU/day of vitamin D3 for a year, it increased their BMD by 4%. In addition, a third study showed that when older women took 1000 IU/day of vitamin D3 for 8 years, there were significant decreases in their rate of hip fracture. These studies show how taking vitamin D3 can help with maintaining bone health by preventing osteoporosis or fractures.

Why is flaxseed oil essential for the human body?

Flaxseed oils can be an excellent source for your omega-3 fatty acids. Omega-3 fatty acids are essential fats that your body cannot produce on its own, which means that you should get them through your diet. There are three types of omega-3s: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). They all have very similar characteristics, but they also have different effects on human physiology. For example, ALA is mainly found in plant sources, such as flaxseed oils, chia seeds and walnuts. ALA plays a vital role in maintaining heart health because it helps reduce inflammation and blood pressure levels. It also supports brain function, which is essential for good cognitive health.
