Nourishing Your Brain: A Guide to Supplements for Cognitive Health & Mental Clarity

Our brains are remarkable organs — responsible for everything from memory and focus to mood and decision-making. Yet in our busy modern lives, cognitive performance is often the first thing to suffer. The good news is that a growing body of nutritional science supports the role of specific supplements in maintaining normal brain function, psychological wellbeing, and protection from oxidative stress.

At Elixir Health & Wellbeing, we’ve curated a premium range of brain health supplements from trusted, ethical brands. Here’s a guide to the key ingredients and what the science says.

1. Omega-3 (DHA & EPA)

DHA (docosahexaenoic acid) is one of the most important structural fats in the brain, making up a significant proportion of the brain’s grey matter. Importantly, DHA carries an authorised health claim: DHA contributes to the maintenance of normal brain function (at a daily intake of 250mg). EPA and DHA together also contribute to normal heart function.

Our range includes high-strength options such as Wiley’s Wild Alaskan Peak EPA (750mg EPA per capsule), easy-swallow mini softgels for those who struggle with larger capsules, and Natures Aid Fish Oil 1000mg for everyday maintenance — all from sustainably sourced fish.

Suggested use: 1–2 capsules daily with food. Look for molecularly distilled products to ensure purity from heavy metals and PCBs.

2. Lion’s Mane Mushroom

Lion’s Mane (Hericium erinaceus) is one of the most exciting functional mushrooms in the wellness world. Mushrooms For Life’s Organic Lion’s Mane uses a dual-extract method from the fruiting body — not mycelium — providing a minimum of 10% beta-glucans and 2% hericenones, the key bioactive compounds unique to this species.

Traditionally used in East Asian medicine, Lion’s Mane is increasingly studied for its potential role in supporting cognitive health, mood, and neurological function. It is also associated with digestive and immune support.

Suggested use: As directed on pack. Best taken consistently over time for cumulative benefit.

3. Ashwagandha

Ashwagandha (Withania somnifera) is one of Ayurveda’s most revered adaptogenic herbs, used for thousands of years to support mental resilience, relaxation, and vitality. Our range includes Viridian’s certified organic extract standardised to a minimum of 5% withanolides, and Solgar’s Ultimate Calm combining KSM-66® Ashwagandha with Saffron® for emotional wellbeing and a positive mood.

Adaptogens like ashwagandha are thought to help the body and mind respond more effectively to everyday stress, supporting a sense of calm and optimal mental activity.

Suggested use: 1 capsule daily. Adaptogens are typically taken in cycles of 6–8 weeks.

4. Ginkgo Biloba

Ginkgo Biloba is one of the world’s oldest living tree species and one of the most widely used botanical supplements globally. Solgar’s Ginkgo extract contains both flavonoids and terpenoids — compounds with strong antioxidant properties — and has a long traditional association with mental alertness and cognitive support.

Suggested use: As directed on pack. Not recommended during pregnancy or alongside blood-thinning medication without medical advice.

5. Viridian Peak Focus (Lemon Balm & Sage)

Peak Focus is a certified organic, caffeine-free formula combining two clinically studied botanical extracts: Bluenesse® Lemon Balm and Cognivia™ Sage. Studies on these proprietary extracts have shown benefits for concentration, attention, and memory — with effects felt within 1–2 hours of taking.

It’s an ideal option for those seeking a natural, stimulant-free focus supplement for work, study, or everyday mental performance.

Suggested use: As directed on pack. Suitable for vegans.

6. B Vitamins (B6, B12 & B-Complex)

The B vitamin family plays a central role in brain health. Key authorised health claims include:

  • Vitamin B6 contributes to normal psychological function and normal functioning of the nervous system
  • Vitamin B12 contributes to normal psychological function, normal functioning of the nervous system, and reduction of tiredness and fatigue
  • B vitamins collectively support energy-yielding metabolism and the reduction of tiredness and fatigue

Viridian’s HIGH TWELVE provides 500µg of B12 in two bioavailable forms (methylcobalamin and adenosylcobalamin), alongside a full B-complex. HIGH SIX offers elevated B6 with full B-complex support. Both contain 100% active ingredients with no artificial fillers.

Suggested use: 1 capsule daily with food.

7. Vitamin E & Vitamin C

Both Vitamin E and Vitamin C carry the authorised claim that they contribute to the protection of cells from oxidative stress — important for long-term brain health, as the brain is particularly susceptible to oxidative damage. Vitamin C also contributes to normal psychological function.

Viridian’s Natural Vitamin E 400IU is naturally sourced from soya bean oil and is better absorbed than synthetic forms. Viridian Extra C 550mg uses lipid metabolites for enhanced bioavailability and rapid absorption.

Suggested use: 1 capsule daily with food.

Building a Brain Health Routine

The most effective approach to cognitive support combines good nutrition, regular exercise, quality sleep, and stress management — with targeted supplementation as a complement, not a replacement. Start with the foundations (Omega-3 and B vitamins), then layer in botanicals like Lion’s Mane, Ashwagandha, or Peak Focus based on your specific goals.

As always, consult your GP or a qualified healthcare professional before starting new supplements, particularly if you are pregnant, breastfeeding, or taking medication.
