Nutrient Status & Health Markers

Four weeks on Huel improved key nutrients and lowered cholesterol, proving complete really means complete.

Summary

A four-week Huel-only intervention demonstrated improved vitamin and mineral levels and reductions in cholesterol and blood glucose. In a four-week Huel-only intervention, participants showed improvements in vitamin and mineral levels, along with reductions in cholesterol and blood glucose, demonstrating that Huel can support micronutrient intake and key cardiometabolic markers.

Key information

Trial title: A Pilot Pre and Post 4-Week Intervention Evaluating the Effect of a Proprietary, Powdered, Plant-Based Food on Micronutrient Status, Dietary Intake, and Markers of Health (read the full paper here)

Partner: Frontiers in Nutrition (2022)

Study type: Peer-reviewed, pre-/post-intervention.

Design: 30 adult participants (20 completed), 4-week Huel-only diet.

Goal: Measure impact on micronutrient levels, blood markers, and body composition.

Outcome 

Participants experienced improvements in micronutrient status and favourable changes in cardiometabolic markers.

Findings

• Vitamin B12 increased by 18%.

• Vitamin D increased by 16%.

• Selenium increased by 21%.

• Total cholesterol decreased by 22%.

• HbA1c, BMI, and waist circumference all decreased.

• Participants maintained or improved levels of key essential nutrients.

• Results showed potential improvements in metabolic health and nutrient adequacy.

Takeaway

Huel delivers science-backed, complete nutrition. In just four weeks, participants improved key vitamin levels and lowered cholesterol, showing that convenience doesn’t mean compromise.

All Huel studies were conducted with independent academic or clinical research partners. One trial was fully independent (Newcastle University), while three trials were conducted by independent organisations with Huel funding. Designs include randomized crossover trials, a peer-reviewed pre-/post-intervention, and consumer perception research. Some findings are published (including Frontiers in Nutrition, 2022); others are under academic review.
