From Chronic Fatigue to Renewed Energy
This anonymised case study shows how a client who had been told by their GP that "everything looks fine" was actually living with four key deficiencies silently draining their energy. A comprehensive blood panel revealed the truth, and targeted IV therapy and vitamin injections helped restore their vitality within weeks.
Client Profile
Age / Gender
Female, 38
Primary Complaint
Persistent fatigue, brain fog
Duration of Symptoms
18+ months
GP Diagnosis
"All blood tests normal"
This client had been experiencing persistent tiredness, difficulty concentrating, poor sleep quality, and low motivation for over 18 months. Their GP had run a basic blood panel and told them everything was normal. They came to Brighton Bio Labs looking for answers.

72% of biomarkers were in range, but the ones that weren't are the exact markers that drive energy production and mental clarity.
The Hidden Gap: "Normal" vs. Optimal for Energy
A standard GP blood test checks whether your results fall within a very broad "normal" range. But "normal" does not mean "optimal." This client's ferritin, vitamin D, B12, and thyroid function were all technically in range, but every single one was at the bottom end, well below the levels needed for sustained energy, mental clarity, and good sleep. This is exactly why a comprehensive panel with optimal range analysis makes such a difference.
Ferritin
Below Optimal Range18
ug/l
At 18 ug/l, this client's ferritin was technically 'in range' by standard lab criteria (15-150), but far below the optimal level of 50-100 needed for sustained energy. Low ferritin is one of the most common causes of unexplained fatigue, particularly in women.
Our recommendation:
Iron infusion recommended to rapidly restore levels, followed by maintenance with dietary changes.
Vitamin D
Below Optimal Range31
nmol/l
At 31 nmol/l, this is classified as 'insufficient' even by standard measures, and well below the optimal range of 75-125 for energy and immune function. Low vitamin D is strongly linked to fatigue, low mood, and weakened immunity.
Our recommendation:
High-dose Vitamin D injection to rapidly restore levels, followed by ongoing supplementation.
Vitamin B12
Suboptimal245
ng/l
At 245 ng/l, this is 'in range' by standard criteria but only at 49% of the optimal minimum of 500. B12 is essential for energy production, nerve function, and red blood cell formation. Suboptimal levels cause persistent fatigue and brain fog.
Our recommendation:
Vitamin B12 injection for immediate absorption, bypassing any gut absorption issues.
TSH (Thyroid)
Suboptimal3.8
mIU/l
At 3.8 mIU/l, this is within the standard lab range but at the higher end, suggesting the thyroid may be underperforming. Subclinical hypothyroidism is a common and often missed cause of fatigue, weight gain, and brain fog.
Our recommendation:
Monitored with repeat testing. Nutritional support with selenium and iodine to optimise thyroid function.

The Treatment Journey
Blood Diagnostics
Comprehensive Wellness & Energy Screen (40+ biomarkers) revealed four key areas below optimal despite being 'in range' by standard criteria.
Results Consultation
Personalised results review identified ferritin, vitamin D, B12, and thyroid function as the root causes of chronic fatigue. Treatment plan created.
IV Therapy & Injections
Energy IV Drip to restore B vitamins and minerals. Vitamin B12 injection and high-dose Vitamin D injection for rapid absorption.
Follow-up & Results
Repeat blood panel showed significant improvement across all markers. Client reported noticeably higher energy, better sleep, and improved mental clarity.

Client Feedback
"I cannot believe the difference. After months of being told I was fine, Brighton Bio Labs actually found what was wrong. The IV drip and injections gave me a noticeable boost within the first week, and by week six I felt like a completely different person. I have energy again, I am sleeping properly, and the brain fog has lifted. I wish I had done this a year ago."
