Lamberts Vitamin D3 1000 iu, Tabs, 120

- +

Our bodies obtain vitamin D (which, strictly speaking is a steroid hormone) from two sources, our diet and from the action of sunlight on our skin which drives the natural production within the body. If we all had plenty of sun then we would have plenty of vitamin D, but in reality we do need to obtain some from our diet, particularly during the winter months and particularly in the elderly as the body's ability to manufacture vitamin D declines with age. Indeed as many as 60 percent of the UK population is vitamin D deficient and low levels have been linked to serious health problems in later life.

This is not surprising when one considers the fact that it is involved in the expression of more than 1000 genes. So whilst it is renowned for its vital role in the maintenance of normal bone health, in reality it actually acts on cells in every organ of the body and has extremely far-reaching effects on human health.

Each capsule of Lamberts® Vitamin D provides 1000iu (in the vitamin D3 form).

Vitamin D3 (cholecalciferol) has a few health benefits, including helping the body absorb calcium. Foods such as fish, beef liver, eggs, and cheese naturally contain vitamin D3. It can also be produced in the skin following exposure to ultraviolet (UV) radiation from the sun.

Supplement forms of vitamin D3 are also available and may be used for general health, as well as the treatment or prevention of vitamin D deficiency.

Vitamin D3 is one of two types of vitamin D. It differs from vitamin D2 (ergocalciferol) in both its structure and sources.
The article explains what vitamin D supplements do and the benefits/drawbacks of vitamin D3 specifically. It also lists other important sources of vitamin D3.

Vitamin D, also referred to as calciferol, is a fat-soluble vitamin (meaning one that is broken down by fat and oils in the gut). It is commonly referred to as the "sunshine vitamin" because the D3 type can be naturally produced in the body following exposure to the sun.

Vitamin D has many functions in the body, chief of which include:

  • Bone growth
  • Bone remodeling
  • Regulation of muscle contractions
  • Conversion of blood glucose (sugar) into energy

Not getting enough vitamin D can lead to an array of health concerns, including:

  • Delayed growth in kids
  • Rickets in kikds
  • Osteomalacia (loss of bone minerals) in adults and adolescents
  • Osteoporosis (porous, thinning bones) in adults

If you do not obtain enough vitamin D to meet the body's needs you are considered to have a vitamin D deficiency. This can be diagnosed through blood testing.

However, the U.S. Preventive Services Task Force does not recommend routine vitamin D screening in adults without symptoms of deficiency.2

Not everyone who is low in vitamin D experiences symptoms. Those who do may notice:3

Muscle and/or bone pain
Muscle weakness
History of fractures
Muscle twitching
If you suspect you could be vitamin D deficient, ask your healthcare provider to test your blood levels or take an at-home test.

Causes for vitamin D deficiency are many, including diseases or conditions that limit fat absorption and the breakdown of vitamin D in the gut. As such, you are at greater risk for vitamin D deficiency if you have:1

  • Celiac disease
  • Crohn’s disease
  • Cystic fibrosis
  • Gastric bypass surgery
  • Liver disease
  • Malnutrition
  • Obesity
  • Ulcerative colitis

People who are older, are housebound, or have dark skin are also more vulnerable to vitamin D deficiency.
Vitamin D deficiency affects almost 50% of the population worldwide.4 Both vitamin D2 and D3 can be used to treat this, with vitamin D3 generally being the preferred choice.

Beyond its use in treating vitamin D deficiency, vitamin D3 may offer health benefits to certain people without such deficiency—in particular, those with high blood pressure or osteoporosis.

Hypertension, more commonly known as high blood pressure, is cardiovascular disease commonly seen in people with vitamin D deficiency.

Recent studies suggest that vitamin D3 may help lower blood pressure in people with hypertension and vitamin D deficiency as well as certain groups of people with hypertension only.

According to a 2019 review of studies in the journal Medicine involving 1,687 people, vitamin D3 was able to significantly reduce systolic ("top number") blood pressure in people over the age of 50 and those with obesity.

This is important because isolated systolic hypertension can increase the risk of stroke, heart disease, and chronic kidney disease over time.

Osteoporosis is a frequent consequence of long-term vitamin D deficiency, so common wisdom would suggest that vitamin D supplements may help prevent or slow the progression of this common, aging-related bone disease. There is some evidence to support this claim.

A 2013 study from the University of Western Australia found that the use of vitamin D3 in nursing home residents aged 70 and over significantly reduced the incidence of hip fractures. In addition, low-dose vitamin D3 (400 IU) also increased bone mass density in the femoral (thigh) bone.

Vitamin D3 is generally regarded as safe, but it can on rare occasions cause toxic effects if you take too much. This is referred to as hypervitaminosis D.

With vitamin D toxicity, the balance of minerals like calcium and potassium is upset. This can lead to a condition known as hypercalcemia, in which too much calcium builds up in the body. This can lead to symptoms like:

  • Stomach upset
  • Nausea
  • Vomiting
  • Constipation
  • Bone pain
  • Muscle weakness
  • An increased risk of bone fractures
