Fee Steinvorth Wants to Calm Your Nervous System

The founder of neoNutritions has a new formula designed to ease chronic stress and calm cortisol.

We caught Fee on the phone from her car in LA — warm, direct, and completely certain about what she’s made. “Anxiety disorders are now the most common mental health condition globally,” she says. “Chronic stress has become so normalised that we have stopped recognising it as the emergency it actually is.” Ultimate Mood is her answer — a once-a-day nervous system nutrition rooted in Ayurveda, Traditional Chinese Medicine, and whole-food science. It supports a balanced mood, healthy cortisol levels, and a calm nervous system using 12 active botanicals, adaptogens, functional mushrooms, and organic fruits that work across multiple pathways to support; stress-hormone regulation, nervous system recovery, emotional resilience, and sleep onset. Ultimate Mood is 100% organic, vegan, and free from fillers, stevia, and synthetic additives.

The results of Ultimate Mood build slowly, which is exactly the point. In the first fortnight, most people notice a gentle softening — an easier slide into evening, less mental noise before bed. By the third and fourth week, that steadiness extends into an emotional resilience to everyday pressures. By weeks six to eight, something deeper has shifted. Recovery from demanding days feels more natural and sleep follows more readily.

The taste, Fee notes, is intentionally unprocessed — earth-forward and honest, with a mild herbal complexity balanced by black currant, fig, and rose. No stevia, no masking agents. What you taste is the formula itself.

For mornings, Fee blends the Steinvorth family shake — made to host any of the neoNutritions formulas and designed to serve three kids. Organic berries (fresh or frozen), one banana, mango if you have it, raw organic whole milk, cacao nibs, and one walnut per child. Five minutes, no fuss, and most of what growing bodies need before heading out the door.

For evenings, Fee takes her Ultimate Mood Inner Calm two hours before sleep as an intentional evening ritual that can be sustained long term. She whisks Ultimate Mood into a slightly cooled chamomile or tulsi tea with a drizzle of raw honey.

Ultimate Mood launches in collaboration with Lykke Li. Put on The Afterparty and let the evening begin.

Fee is our north star for ingredients — this is a woman who has done the work, studied the traditions, and built something with genuine care at its centre. With that in mind, we asked what she reaches for when it comes to skincare to complement the inner work of her formulas.
