Vitamin D: More than a vitamin.
☀️ Vitamin D isn’t actually a vitamin.
It’s a hormone your body creates, and it plays a role in far more than bone health.
Vitamin D receptors are found throughout the body, and research shows vitamin D is involved in 300+ biological processes, including:
• Immune resilience
• Bone density & muscle function
• Cardiovascular health
• Mood regulation & mental health
• Cognitive performance & brain health
• Thyroid and metabolic signaling
Yet here’s where most conversations stop short 👇
Having vitamin D present doesn’t always mean your body can use it effectively.
🧬 Genetics matter.
Variations (SNPs) in the Vitamin D Receptor (VDR) genes can impair how well your cells respond to vitamin D — even if blood levels look “normal.”
This means someone can:
• Get sun exposure
• Take supplements
• Show a “normal” lab value
…and still experience symptoms tied to functional vitamin D insufficiency.
This is why we often pair vitamin D testing with genetic insight and symptom patterns — numbers alone don’t tell the whole story.
🔍 That’s why at Bedrock Nutrition, we don’t aim for minimum adequacy.
We aim for optimized terrain.
📊 Our clinical target:
Vitamin D (25-OH D3): 60–100 ng/mL
Compare that to the conventional “normal” cutoff of ~30 ng/mL — a level that may still be associated with:
• Low mood & depressive symptoms
• Increased anxiety
• Poor immune signaling
• Thyroid dysfunction
• Higher inflammatory burden
This aligns with what leaders in brain health continue to emphasize.
Dr. Daniel Amen recently highlighted that vitamin D deficiency is linked to hundreds of conditions, including depression, cognitive decline, autoimmune disease, and dementia — and that 3 out of 4 Americans now fall below optimal levels.
📌 Testing matters.
We don’t guess. We measure — and we interpret in context.
👉 Take our functional health assessment:
When levels are low or utilization is impaired, D3 paired with K2 becomes foundational for absorption, transport, and safety.
☀️ Sunlight is powerful.
🧬 Genetics influence response.
📊 Testing guides strategy.
This is what building health on bedrock looks like.
