Vitamin D3 25 mcg (1000 IU) Softgels Life Extension

$5.25

Immune, bone & whole body health, value size

Your skin produces vitamin D when in direct sunlight or indoor tanning devices, but that’s not an ideal solution for obvious reasons. Choose a potent vitamin D3 supplement from Life Extension instead.

What Is Vitamin D3?

Supplementing with vitamin D goes a long way. Vitamin D helps preserve youthful cognitive function, supports bone and immune system health, helps maintain already-healthy blood pressure, encourages a healthy inflammatory response and promotes endothelial function. We recommend between about 125 mcg (5,000 IU) to 200 mcg (8,000 IU) of vitamin D3 a day.

Make sure you’re getting enough of vitamin D3, the sunshine vitamin. Add Vitamin D3 to your supplement regimen today.

Vitamin D3 Benefits

Helps maintain youthful, healthy cognitive function
Supports bone health & immune system function
Promotes cardiovascular & endothelial health
Helps maintain blood pressure already within the normal range

Getting Enough of the Sunshine Vitamin

Vitamin D is called the sunshine vitamin because your skin manufactures it when exposed to sunlight, but that shouldn’t be your only source. A vitamin D supplement goes a long way. We recommend about 125 mcg (5,000 IU) to 200 mcg (8,000 IU) of vitamin D3 a day. If your multivitamin already delivers 25-75 mcg (1,000–3,000 IU) of vitamin D, vitamin D3 125 mcg (5,000 IU) is perfect for achieving optimal levels.

Maintaining healthy levels of vitamin D helps preserve youthful cognitive function and offers broad-spectrum benefits for bone, immune system health and more. Here's why you should be making sure you get enough of this essential vitamin every day:

Cognitive health

Vitamin D is important for maintaining cognitive health and function as you age. Healthy serum vitamin D levels have been shown to correspond with better scores on cognitive health tests and better maintenance of cognitive ability in aging individuals.

Bone and immune health

Vitamin D (along with vitamin K and essential minerals) is essential for facilitating the transport of calcium into the bone matrix. This is an important step in maintaining strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function.

Heart health & blood pressure support

Vitamin D helps to regulate the body's calcium balance while facilitating calcium absorption into the bloodstream, promotes a healthy inflammatory response in the cardiovascular system and encourages healthy endothelial function.^7,8 Vitamin D may also help inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.

Getting enough vitamin D

This vitamin D3 supplement delivers 25 mcg (1,000 IU) of vitamin D3 as cholecalciferol per softgel. We suggest that you take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust your dosage. Your optimal blood levels should be 50–80 ng/ml year-round.

Serving Size 1 softgel
Amount Per Serving
Vitamin D3 (as cholecalciferol)	25 mcg
Other ingredients: extra virgin olive oil, gelatin, medium chain triglycerides, glycerin, purified water, rosemary extract.

Dosage and Use

Take one (1) softgel daily with food, or as recommended by a healthcare practitioner.

Caution

Individuals consuming more than 50 mcg (2000 IU)/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 10000 IU per day unless recommended by your doctor. Vitamin D supplementation is not recommended for individuals with high blood calcium levels.

Bone building and immune modulating
Easy-to-swallow mini softgels
Contains 5000 IU Vitamin D3 per softgel

Vitamin D3 is a crucial nutrient for overall health, specifically maintaining strong muscles, bones, teeth and immune system. However, millions of individuals are deficient in this life-sustaining vitamin. In addition to supporting bone health‚ research shows that D3 deficiency is linked to a host of conditions that present serious health risks. Zahler's Vitamin D3 provides all the benefits of vitamin D without the risk of unprotected exposure to UVB rays.

More about Vitamin D3
Officially known as cholecalciferol, Vitamin D’s nickname, the “sunshine vitamin,” offers insight into one of the ways humans can get the vitamin. Aside from exposure to sunlight, you can also obtain Vitamin D3 by eating certain foods, such as fish, eggs and milk fortified with the vitamin. However, many people do not have adequate levels of Vitamin D3 in their systems and therefore require supplementation.

Product FAQs

Where is your vitamin D sourced from?
The Vitamin D3 (cholecalciferol) is naturally sourced from lanolin, the wool of sheep.

What is the difference between Vitamin D2 and D3?
Vitamin D3 (cholecalciferol) is the natural form of Vitamin D that your body makes from sunlight. D3 can also be sourced from lanolin. On the other hand, Vitamin D2 (ergocalciferol) is cheaper to produce, but research shows that it is less effective in raising Vitamin D levels.

How can I know how much Vitamin D to take daily?
A typical adult can take approximately 2,000 to 3,000 IU of vitamin D3 daily. However, since D3 is a crucial vitamin which is essential for so many bodily functions, it is recommended to take blood work once in a while to ensure that the vitamin D level is within the normal range, not too high and not too low. Generally speaking, adults with low Vitamin D levels are recommended by health professionals to take 5000 IU of vitamin D daily.

Suggested use

Take 1 softgel daily with food, or as directed by a healthcare practitioner.
