HOW IT WORKS

Vitamin D comes in two forms: D2 and D3.
Of the two, D3 is more bioactive. The body synthesizes vitamin D3 from cholesterol and sunlight; which makes it difficult to obtain adequate amounts of vitamin D during cloudy or winter months. In the body, vitamin D is responsible for maintaining normal blood levels of calcium and phosphorus, and helping to build strong bones.
It works with other vitamins, minerals and hormones to promote bone mineralization. Research shows that vitamin D may help support a healthy immune system by regulating lymphocyte function, cytokine production and macrophage activity.
Studies also show that Vitamin D may improve mood.

WHY VITAMIN D3

Vitamin D3 offers a host of health benefits.
It supports both the innate and adaptive branches of the immune system. 
It influences mood, and, along with calcium and other minerals, it supports bone health. 
On top of all these gains, Nature’s Sunshine’s Vitamin D3 partner supplies us with a super-clean nutrient; one that is proudly allergen-free and non-GMO project verified.

THE STORY BEHIND VITAMIN D3

Vitamin D was discovered as researchers worked to end rickets, a bone disease in children, in the early 20th century. Sir Edward Mellanby discovered that cod liver oil—a source of vitamin A—could alleviate symptoms of rickets. Later, Professor Elmer McCollum tested cod liver oil without vitamin A.
When it still prevented rickets, he assumed that a yet-undiscovered nutrient was responsible. He named this nutrient vitamin D.
In 1937, vitamin D3 was identified by former Nobel-prize-winner Adolph Windaus and his associate. They found that vitamin D3 formed in the skin after it was exposed to sunlight.
In 1952, a team of researchers discovered that vitamin D did not actually put minerals into the bone, but rather mobilized calcium from the bone into the plasma. This led to the understanding of vitamin D’s role in maintaining serum calcium, which affects both skeletal strength and neuromuscular function.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
