Britni Martinelli is a Functional Nutritionist specializing in the gut microbiome, mitochondria enhancement,hormones, metabolism and the founder of Nourishing Nelli.
She helps individuals improve digestion, obtain more energy, support hormone balance, manage weight, and feel confident around food through a science-based approach that turns nutrition into something simple, empowering, and sustainable — built for everyday life.
The Nourishing Nelli Method
Britni created her signature framework, Cognitive Nutrition & Wellness, to provide a clear foundation for understanding food and building habits that actually last.
Rather than rules, restriction, or perfection, this method teaches the strategies and skills that make eating feel intuitive, nourishing, and consistent — so clients can feel at ease in their body and confident in their choices.
Her approach blends:
How to obtain the foundational mechanisms for lasting health
gut digestion and microbiome support
nervous system regulation
metabolic and energy optimization
Clients learn why certain foods and habits work for their body — and how to repeat those results without overwhelm.
At Nourishing Nelli, nutrition is defined as anything that feeds you — physically or mentally.
Food is only one part of the equation. Everyday habits, stress, environment, light and mindset all influence how the body responds. Nelli helps clients create supportive structure around these elements so healthy choices feel natural — not forced or stressful.
Who This Is For
Nelli works best with individuals who:
experience bloating, digestive discomfort, or low energy
feel overwhelmed by conflicting nutrition advice
want weight loss or body recomposition support without dieting
are ready for a plan that fits real life, not perfection
want clean, supportive meal planning delivered weekly
Through personalized support, education, and practical tools, Nelli guides clients toward sustainable change that feels doable.
Nourish to Flourish.
