Life Extension Vitamin D3: Everything You Need to Know


What is Life Extension Vitamin D3? Why is Vitamin D3 important? What do you get when you take Life Extension Vitamin D3? Discover the answers to these questions and more!

The D vitamins are fat-soluble vitamins that play a crucial role in calcium absorption and bone health, as well as immune function. Your skin produces vitamin D when exposed to sunlight, but due to the skin cancer risk, many people use sunscreen or avoid sun exposure altogether, which prevents the body from producing vitamin D. Many types of milk and dairy products are also fortified with vitamin D.

Still, many people don’t get enough vitamin D and need to take a supplement. There are two forms of vitamin D dietary supplements: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).

In this article, we focus on Vitamin D3 (cholecalciferol) and one specific supplement that provides it – Life Extension Vitamin D3. Keep reading to learn more about Vitamin D3 and Life Extension Vitamin D3 – from its product information, benefits, reviews, and more.

What is Vitamin D3?

Also known as the ‘sunshine vitamin’, Vitamin D3 provides numerous benefits throughout your body. As it circulates through your bloodstream, it aids in the absorption of phosphorus and calcium, which helps keep your bones strong. Moreover, it’s involved in a healthy immune system, and it’s beneficial to heart health, mood, and even weight loss. You can get vitamin D from food and supplements, and your skin produces D3 when it’s exposed to sunlight.

Sources.If you’d like to increase your Vitamin D levels, you can get more sunlight, increase the amount in your diet, or take supplements. However, it’s difficult to get enough Vitamin D3 through diet alone, especially if you don’t eat a diet very rich in the foods below:

Supplements. Supplements like Life Extension Vitamin D3 are the easiest way to ensure you’re getting enough vitamin D3 every day, and evidence suggests supplements are just as effective as sunlight and food sources.

Health Benefits. Vitamin D3 offers many health benefits, including, but not limited to:

  • Immune Health. Research has shown that Vitamin D can boost your immune health and may help protect against pneumonia and acute respiratory infections.
  • Bone Health. Vitamin D is known to help both the muscles and bones. Research shows that Vitamin D can help reduce fractures and improve muscle strength. Moreover, high levels of dietary vitamin D3 may be suitable for achieving a higher peak bone mass in adulthood, thus helping prevent osteoporosis.
  • Weight Loss. In one study, postmenopausal women were given Vitamin D3 supplements (compared with a placebo) for a weight loss intervention. Results revealed that the women who had adequate levels of Vitamin D3 lost more body fat, saw a greater reduction in waist circumference, and lost more weight.

When I first started taking it, my Vitamin D level was at 20. 2.5 months later of taking it every day I jumped to 67. My favorite since! I started buying it for my parents, son, and ex-husband but I tell everyone about this vit d brand.” – Azucena

“I have been having lots of brain fog, extremely tired, & anxiety and depression, which I haven’t really struggled with as an adult. A friend told me to get some vitamin D because what I described to her sounded like a deficiency. Didn’t think of that before. Immediately bought these knowing what a lack of vitamin D does to the body. I don’t have the brain fog, anxiety and depression no longer plague my life, and I have much more energy. These tiny vitamins are a lifesaver.” – Elizabeth

“As someone who was extremely low in Vit. D and suffers from ME (CFS) my doctor recommended this Vit D supplement. I started with 1,000 MG a few times a day and every week I increased my dose eventually ending up with 2-5000 MG doses daily. I usually get nauseous when taking supplements but I haven’t experienced that with this Vit D in this brand.

I make sure to take them halfway through breakfast and the same with Dinner, putting something in my stomach first but making sure I have something to eat after as well. I highly recommend this product.”

I have a rather sensitive stomach and found no aftertaste and it doesn’t repeat on me.” – Nitty

“Okay na okay tong vitamin na ‘to, and what I like best about it is walang after taste, unlike other vitamin supplements.” – Troy

My skin has always been very oily, but the oil production is greatly reduced when I take these Vitamin D soft gels. All my breakouts have stopped. My friend who is a health specialist recommended this brand to me. I swear by it now. I never get any sun because I work indoors. I have noticed my mood is better also when taking these vitamins. My husband takes them now too!” – AC
