What does the clinical study say about Vitals⁺?

Vitals⁺ isn’t just built on science—it’s backed by it. We conducted a pilot clinical trial to explore its impact on nutritional status and mental well-being in healthy volunteers.

🔬 What was the study?

A team of researchers from Heights and King’s College London conducted a study to test how daily Vitals⁺ affects key B-vitamin levels and mood in healthy adults.

Over 8 months, participants took Vitals⁺ daily. Before and after the intervention, we measured:

• B-vitamin blood biomarkers (how much of the nutrient is readily available in the body)

• Mental well-being, using validated clinical questionnaires like the POMS, GHQ-12, and PSS

🤔 What did the study find?

Improved nutrient biomarker status
Thiamine (B1), riboflavin (B2), folate (B9), and vitamin B12 levels significantly increased.
93% reached optimal thiamine status, and 100% improved their riboflavin levels to optimal. There was also a 43% improvement in red blood cell folate levels and a 43% increase in serum B12 concentrations. 

Positive impact on mental well-being
Participants experienced significant reductions in fatigue, confusion, and tension. There were also signs of a reduction in psychological distress.

🤔 Why does it matter?

These B vitamins are essential for neurotransmitter production and energy metabolism—so topping them up can make a big difference in how you feel, especially in today’s nutrient-depleted world.

Our Head of Science and Research, Dr. Harry Jarrett, excitedly presented this Vitals⁺ data at the Nutrition Society Winter Conference in January 2025.
