Immune, bone & whole body health
Many of us don’t get enough vitamin D from sunshine and diet alone—but we need this nutrient for healthy bones and a strong immune system. Our high-potency supplement fills in the gaps.
What Is Vitamin D3?
Basking in the sunshine is one of life’s greatest pleasures—and not only does it feel good, it’s good for us in moderation, because sunlight prompts our bodies to manufacture the essential nutrient, vitamin D. But it’s simply not possible for many of us to get enough vitamin D naturally. That’s why you need a potent vitamin D supplement.
Make sure you’re getting enough of the sunshine vitamin with this high-potency, easy-to-swallow vitamin D formula.
Vitamin D3 Benefits
- A must-have supplement for bone health and immune support
- Supports your heart, brain and more
- Potent formula in an easy-to-swallow softgel
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.
Why Should I Supplement With Vitamin D3?
Customer: To me, there's nothing better than being outside on a really nice day. Whether I'm working in my garden or taking a walk with my family, we all love the outdoors. But during my last checkup, the doctor noticed that I wasn't getting enough vitamin D.
Michael A. Smith, MD: From your brain to your heart, your bones to your immune system, vitamin D affects nearly every cell in your body and is critical for optimal health. Even if you spend a lot of time outdoors, your body may not be producing enough of this important vitamin. In fact, studies show that people are really low in vitamin D—and that's why doctors are recommending it to their patients more than ever.
Customer: So, my body needs more vitamin D, but there are all these different doses and options. How can I decide which is best for me?
Michael A. Smith, MD: Like all of our products, Life Extension’s Vitamin D3 is made with the highest quality standards. We recommend taking 5,000 international units a day, but we offer doses ranging from 1,000 to 7,000 units depending on your vitamin D blood level. Be sure to check with your doctor to see which one is right for you. We also offer Vitamins D and K with Sea-Iodine™ for a complete vitamin D formulation.
Customer: Three weeks in, and vitamin D has really made an impact on my whole life. I have more energy and overall, I feel for lack of a better word…sunnier.
Dr. Michael A. Smith, MD: Director of Education and Spokesperson for Life Extension.
Product Details
Your skin produces vitamin D when in direct sunlight, but you should not get your vitamin D from unprotected sun exposure or indoor tanning devices. Supplementing with vitamin D goes a long way towards inhibiting deficiency: we recommend about 5,000 IU–8,000 IU of vitamin D3 a day. If your multivitamin already delivers 1,000–3,000 IU of vitamin D, Vitamin D3 5,000 IU is perfect for achieving optimal vitamin D levels.
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. Vitamin D also helps 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 5,000 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.

Product Details
Your skin produces vitamin D when in direct sunlight, but you should not get your vitamin D from unprotected sun exposure or indoor tanning devices because of the potential effects on skin health.
Iodine is a trace element essential for the production of thyroid hormones, and vitamin K is an essential nutrient that promotes both arterial and bone health.
Iodine is essential for thyroid health
Iodine is a trace element necessary for the production of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). Iodine is abundant in seafood and sea vegetables, but not everyone likes or has access to marine foods, and vegan diets sometimes lack adequate iodine.
Commercial salt makers add iodine to table salt to make up for this potential deficiency. However, we now know the health risks of eating too much salt, so health-conscious people may miss out on an easy source of iodine. Vitamins D and K with Sea-Iodine™ delivers 1,000 mcg of iodine to support healthy iodine levels.
Vitamin K1 and two different types of K2
Vitamin K helps inhibit calcium buildup in your arteries while promoting healthy calcium absorption into your bone matrix. K1 is the most common form of vitamin K in the diet, coming primarily from leafy green vegetables—though vitamin K1 isn’t well absorbed from these foods.
Vitamin K2 is found in cheese, eggs and fermented soybeans. It has been shown to be more bioavailable than K1 and to remain active in the body far longer. The MK-4 and MK-7 forms of vitamin K2 also provide important benefits but have different tissue distributions and bioavailability, so it’s important to take both. This formula contains both forms of vitamin K2.
Vitamin D3 for cognitive, bone and immune health
Healthy serum vitamin D levels have been shown to correspond with better cognitive function. Vitamin D, along with vitamin K and essential minerals, is necessary for facilitating the transport of calcium into the bone matrix for strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function.
Some people may need 125 mcg (5,000 IU) to 200 mcg (8,000 IU) of vitamin D3 a day to achieve healthy blood levels of vitamin D. If your multivitamin already delivers 25-75 mcg (1,000–3,000 IU) of vitamin D, adding Vitamins D and K with Sea-Iodine™ may help achieve healthy vitamin D levels.
Vitamin D3 for heart health and blood pressure support
Vitamin D promotes a healthy inflammatory response, supports cardiovascular health and encourages healthy endothelial function. Vitamin D also helps inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.
Getting enough vitamins D and K and iodine
This vitamin D3 supplement delivers 125 mcg (5,000 IU) of vitamin D3 as cholecalciferol per capsule. 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.
Ensure you get enough of these three essential nutrients with Vitamins D and K with Sea-Iodine™.

Jarrow Formulas® Vitamin D3 (cholecalciferol) may help improve vitamin D status better than equivalent amounts of ergocalciferol (D2).* D3 is also the form produced by skin with UVB exposure (sunlight). Vitamin D3 is converted to its hormonally-active form, calcitriol, which enhances dietary calcium and phosphorous absorption, supports the production of osteocalcin (a structural protein in bone), and stimulates the vitamin D receptor in innate immune cells to support a healthy immune response.
