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.

Advanced ashwagandha complex with L-Theanine & magnesium

Stress can have a range of negative physiological effects on the body. This includes increased cortisol levels, which may disrupt the body's hormonal balance and suppress the immune system. Nervous system imbalances can also occur which may affect the balance of neurotransmitters leading to an imbalanced mood. Stress also creates a higher demand for a number of vitamins and minerals, particularly magnesium, zinc, and B vitamins which are collectively essential for nervous system function, energy metabolism, and immune function.

This advanced multi-action formula delivers a unique blend to provide comprehensive support for times of stress. Ashwagandha supports relaxation and calmness and helps the body to deal with stress. Zinc contributes to normal cognitive function. Vitamin B6, B12 and folate contribute to normal homocysteine metabolism.

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.

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.
