Great for: times of stress, supporting the nervous system and the production of neurotransmitters, important for sleep and mood health

This advanced multi-action formula delivers a unique blend of ingredients to provide comprehensive support for times of stress. Ashwagandha is best known for its relaxing properties by improving the body’s resistance to stress. We provide Ashwagandha as KSM-66, the most scientifically supported form, containing a high concentration of active compounds from the root-only. Synergistic L-Theanine promotes feelings of relaxation. Stress depletes the body's nutrient stores, particularly magnesium, zinc, and B vitamins, so this complex includes these essential nutrients which also contribute to the reduction of tiredness and fatigue, a common experience of long-term stress.

Root-only extract ashwagandha KSM-66

KSM-66 is the most scientifically supported form of ashwagandha, standardised to contain a high concentration of active compounds using root-only extracts, called withanolides, at 5%. Ashwagandha improves the body's resistance to stress but has a short half-life so we recommend split dosing the 2-daily serving. This product is not recommended during pregnancy or breastfeeding.

Produced using "Green Chemistry" principles

Rather than milk extraction, the ashwagandha is extracted from root-only using a patented water process, resulting in a vegan-certified product. No alcohol or synthetic solvents are used in this process, and this supplement has been formulated without any unnecessary extra ingredients; free from artificial colours or flavours, magnesium stearate and silicon dioxide.

Plant based & bioavailable nutrient forms

Extracted from natural green tea, we add L-theanine to this complex, and our magnesium is sourced from mineral-rich seawater. This supplement also provides a full B-complex in bioactive forms, including folate as L-methylfolate instead of standard folic acid, and vitamin B12 as methylcobalamin. Highly absorbable chelated zinc bisglycinate is also added for maximum benefits.

How Ashwagandha+ L-Theanine & Magnesium compares

Not all ashwagandha are formulated the same. See how ours compares.

	Ashwagandha+ L-Theanine & Magnesium	Typical ashwagandha
Clinically studied ashwagandha	600 mg KSM-66 root extract	Varies
Standardized potency	5% withanolides	Varies
Combined with L-theanine	200mg	Often not included
Combined with magnesium	90mg marine magnesium	Often not included
Added nutritional support	Full B-complex and zinc	Rarely included
Sustained daily support	Split morning and evening dosing	Typically once daily

What to expect

Magnesium and L-theanine build steadily — here's a realistic timeline of how your family may notice the difference.

What you may notice

You may feel calmer, more emotionally balanced and better able to manage everyday pressures, without feeling drowsy.

With consistent use

Support for stress and emotional wellbeing builds over several weeks, while key nutrients support energy production and healthy nervous system function.

Good to know

The formula is designed to promote calm, but B vitamins can feel energizing for some. Splitting the daily serving between morning and later in the day can provide more balanced support.

Relaxation & sleep

Folate plays an important role in cell division, including normal maternal tissue growth during pregnancy. As low folate status is a risk factor in the development of neural tube defects, taking a folate supplement is ideal for women of childbearing age or for those planning to conceive. Folate is particularly important to take prior to conception and until the twelfth week of pregnancy.

Mental performance

Folate supplementation may help to reduce tiredness and fatigue. As folate is necessary for proliferation of cells, low folate status can negatively affect the production of red blood cells. This may result in anaemia due to insufficient numbers of red blood cells which are required for oxygen transfer. The reduced oxygen-carrying capacity of the blood leads to symptoms of weakness, fatigue, irritability, and shortness of breath.

Energy levels

Whilst initially stress may boost feelings of energy, as some of the nutrients essential for energy production are quickly depleted. When stress continues long term it can lead to fatigue. This synergistic Ashwagandha complex delivers magnesium and a full B-complex; folate, magnesium, niacin, pantothenic acid, riboflavin, vitamins B6 & B12 contribute to the reduction of tiredness and fatigue.

"After two weeks, my 6-year-old started asking for her 'calm gummy' before bed. She falls asleep faster, fewer meltdowns at dinner, and I'm sleeping better too. It's a non-negotiable in our nightly routine now."

FAQs

This depends on several factors, including your desired outcomes and why you're taking Ashwagandha+. That said, many people start to feel the relaxing effects of L-Theanine and Magnesium within a few hours. However, the full adaptogenic benefits of KSM-66® Ashwagandha for stress resilience typically build up over 2 to 8 weeks of consistent use. Consistent daily intake is highly recommended to help the nutrients replenish the body's stores and support the nervous system long-term.

Yes, you can generally take Ashwagandha+ alongside other supplements. It is commonly paired with omega-3 fish oils or magnesium supplements to support relaxation and nervous system function. However, since this complex already contains B vitamins, zinc, and magnesium, consider upper limits when combining it with a high-strength multivitamin or another B-complex to avoid exceeding tolerable upper limits for daily intake of these nutrients. Generally, you may take 1 extra capsule or tablet of magnesium daily alongside this supplement.

You can take Ashwagandha+ at any time of day, but we generally recommend splitting the daily dose: one capsule after breakfast and one after dinner. This provides balanced support throughout the day and suits those looking to feel calmer, more resilient to everyday stress and better supported during periods of tiredness or burnout.

Although ashwagandha and L-theanine promote feelings of calm, Ashwagandha+ also contains B vitamins to support energy metabolism, which some people find more suitable earlier in the day. If sleep is your only concern, we recommend trying our Pure & Essential High Strength Magnesium Glycinate first.
