Natural Factors Vitamin D3 supports the development and maintenance of bones and teeth, while helping the body absorb calcium and phosphorus. Each drop of this easy-to-take liquid formula provides 1000 IU of vitamin D3 in a base of MCT oil from coconut and RSPO-certified palm kernel for enhanced absorption.

Natural Factors Vitamin D3 1000 IU is a potent liquid supplement carefully blended with medium chain triglyceride (MCT) and flaxseed oils. Known as the “sunshine vitamin”, vitamin D is usually synthesized by the skin through sun exposure. However, many experts recommend supplemental vitamin D as decreased sun exposure puts many at risk of vitamin D deficiency. Vitamin D3 is the preferred cholecalciferol form, which is the most biologically active form of vitamin D.

Vitamin D3 is essential for strong bones and teeth as it increases the body’s absorption of calcium and phosphorus from food. When combined with adequate calcium intake, it helps prevent the brittle, weak bones of osteoporosis. Vitamin D supplementation is important during the winter season when there is limited sunlight and the body is not able to produce its own vitamin D sufficiently. People with lactose intolerance, digestive problems, breastfed infants, individuals with darkly pigmented skin, and adults over 50 years are more likely to need additional vitamin D.

Vitamin D3 1000 IU is unflavoured and contains 500 drops per bottle. It is free from artificial colours, preservatives, sweeteners, and GMOs, making it a recommended product for vitamin D support during pregnancy and lactation.

Good! I would buy this again if needed.
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
Good! I would buy this again if needed. The best oil to use in a KIA, IMO. Keeps it clean and might help prevent oil burning. Your KIA needs the best oil you can feed it. They are known for failing engines so why not give it the best, especially if its out of warranty like mine!

USE THIS 3 yr old-10yr old cars But it is not for use for classic muscle car-flat tappet cams
Style: Restore & Protect, Size: 5 QT, Configuration: 5W-30
Valvoline has come up with a tested, amazinng engine oil for not the newest cars..but for cars say 3-10 years old that may have some varnish-sludge build up..works slowly enough over time so it doesnt suddently clog the filter, but DO change oil and filter at 3500, not more. In fact 3500 to 4K max for ANY car, any time. DO NOT go longer as some mfg or oil say you can. Tests show that sludge builds up. This oil is NOT for classic muscle cars with flat tappet cams.

A fascinating glimpse into the undoing of the Confederacy
Format: Paperback
This dense and and well-written book includes some really interesting insights into how the Confederacy was formed, but then ultimately challenged and destroyed by some of the people it excluded. In Confederate Reckoning, we get to learn about the epic political battle in which White women and slaves in the South helped to undermine the Confederacy and determine the outcome of the Civil War.

Excellent book!
Format: Paperback
I think this is a fabulous book. I have always been interested in the causes of the civil war and this book presents an interesting, almost fascinating perspective, which I havent' seen in other books. I have also been reading James Oakes fabulous "Freedom National" and the two books complement each other extremely well. McCurry's book is not of the quality that Oakes book is but not much is. I cannot understand the criticism of her writing. I find her writing to be very good...admittedly some of the sentences are too long and a few ill defined names but this is a very well written book. Although we have all studied some version of much of this material before I find it hard to believe that almost anyone won't be astonished by the magnitude of the task the confederacy was attempting to take and its inherent stupidity or maybe a better description would be craziness of these people. Good book!
