After testing thousands of patients at Nutrition Connection Balance for Vitamin D3, we see the same thing over and over:
👉 Without a supplement, almost everyone is below optimal levels.
And “normal” lab ranges? Often set way too low.
Where we see people feel their best:
• Women: 75–100 ng/mL
• Men: 65–100 ng/mL
• Never below 50
Why it matters: optimal Vitamin D supports your mood, metabolism, immune system, brain health, bones, and muscle strength.
But don’t guess your levels. Test them.
Use a quick at-home finger prick or a standard blood test, supplement with high-quality Vitamin D3, and retest every 6–12 months.
