3 keys to Vitamin D - vitamins, K2D3,\

Knowing is half the battle, right? Here is the science on Vitamin D.

1️⃣ Vitamin D is essential for helping the body absorb and retain calcium and phosphorus. Vitamin D is important for a healthy heart and blood vessels for normal blood pressure. Vitamin D is key to building and maintaining healthy bones, muscle movement, nerve connections in the brain, and promoting immune health. Vitamin D is important for mental health (serotonin and melatonin regulation for mood and sleep).
2️⃣ The daily RDA (recommended daily allowance) for 19 years and older is 600 IU (15 mcg) daily (unless you are older than 70, for which 800 IU [20 mcg] daily is suggested)
3️⃣ The Tolerable Upper Limit Level (maximum daily intake unlikely to cause harmful effects on health) for Vitamin D is 4,000 IU (100 mcg) [Institute of Medicine / Harvard T.H. Chan School of Public Health]

Therefore, here are the keys to using Vitamin D correctly.
1️⃣ You don’t need more than 4,000 IU per day. More than 4,000 IU per day is considered to not only be unnecessary but may be toxic (unless your doctor dictates you need more than 4,000 IUs for your situation).
2️⃣ “Most studies show that vitamin D3 is more effective than vitamin D2 at raising blood levels of calcifediol.” (“Vitamin D2 vs. D3: What’s the Difference?” Healthline.com)
3️⃣ Vitamin D works best when taken with Vitamin K2. The best form of K2 is MK-7. “…vitamin D does not fully control where the calcium in your body ends up. That’s where vitamin K steps in.” (“Is Vitamin D Harmful Without Vitamin K?” Healthline.com)

When we formulated our Vitamin D product, we put the science into the formulation.

The K2 is sourced from chickpeas.
The D3 is sourced from New Zealand lanolin.
