Vitamin D3

Vitamin D is an essential fat-soluble vitamin and hormone precursor that is critical for numerous aspects of your health, including its most well-known role in supporting bone growth and bone remodeling. *

The "sunshine vitamin" also is needed for calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to support normal bone mineralization. *

Vitamin K2

Our D3 K2 supplement contains the premium, clinically-studied form of Vitamin K2 shown to be the most effective: menaquinone-7 (MK-7) as Mena-Q7. *

Vitamin K2 helps synthesize crucial bone proteins, which allows vitamin K2 to further support healthy bone metabolism. It also helps the body properly utilize calcium to build healthy, strong bone tissue. *

Research indicates that vitamin K2 may help attenuate age-related stiffening of the artery walls, enhance vascular elasticity, and Vitamin K2 also supports cardiovascular health by inhibiting calcium deposits in the arteries and blood vessels. *

Why D3+K2?

While vitamin D ensures that calcium is properly absorbed, vitamin K makes sure the calcium is integrated into bones. Without one or the other, calcium cannot do its job effectively. *

Great value: These are my go-to work from home shirt
Material Type: Recycled Polyester, Color: Blue, Size: X-Large
I’ve been pleasantly surprised by these shirts and wear them weekly for Zoom calls, since I’m still working from home these days. I figured at the price point it was worth trying them out, and now I’ve bought several in different colors. They aren’t super soft, but they are comfy and look nice. I’m 6’1” ~220 pounds, and the XL slim fit still has plenty of room. I imagine the regular cut is incredibly boxy and oversized. The difference between polyester vs recycled polyester is inconsequential. I typically buy expensive golf shirts, and these definitely aren’t as nice. They are a fraction of the cost though and a great “beater” work shirt / hang out shirt. It’s nice wearing something that looks and feels decent, but if something happens to it, you can toss and it and pick up another for the cost of a chipotle burrito.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
