Vitamin D and Omega-3: Why “More” Is Not Always Better
Recent media reports have warned against unmonitored vitamin D use, while omega-3 supplements continue to be widely promoted.
The clinical reality is simple:
Supplementation should be personalised — not guessed.
Vitamin D: Essential but Easy to Overdo
Vitamin D supports:
- Bone strength
- Immune regulation
- Muscle function
However, excess vitamin D can cause:
- High calcium levels
- Kidney strain
- Cardiovascular risk
Symptoms of excess are often silent.
Omega-3: Helpful for Some, Not All
Omega-3 fatty acids may support:
- Heart health
- Inflammation balance
- Brain function
Benefits vary depending on:
- Baseline levels
- Diet
- Existing medical conditions
- Medication use
Why Blood Testing Comes First
Rather than self-supplementing, testing shows:
- True deficiency
- Optimal dosage
- When supplementation is unnecessary
MDC Nutrient Testing Options
Vitamin & Metabolic Safety Markers
| Test | Why It Matters |
|---|---|
| Vitamin D (25-OH) | Identifies deficiency or excess levels |
| Calcium | Detects risk of vitamin D over-supplementation |
| Full Blood Count | Assesses overall health and immune status |
| Inflammation Markers | Indicates chronic inflammatory burden |
| Lipid Profile | Provides cardiovascular health context |
IV Therapy: When Is It Appropriate?
IV therapy is used selectively, not routinely.
At MDC, IV therapy may be considered when:
- Oral absorption is poor
- Deficiency is clinically confirmed
- Rapid correction is needed
IV therapy does not replace diet or lifestyle.
MDC’s Evidence-Led Approach
- Measure first
- Correct safely
- Monitor outcomes
- Avoid unnecessary treatment
This protects patients from harm.
