Essential nutrients, minerals and vitamins

Magnesium

Magnesium is crucial for energy production, muscle function, and hormonal balance, yet deficiencies are often undiagnosed, particularly in women. Factors such as menstrual cycles, pregnancy, menopause, and stress can deplete magnesium levels, leading to fatigue, cramps, hormonal imbalances, and even mood disorders.

Our magnesium blood test uses a precise serum analysis to measure your magnesium status, providing accurate insights into deficiencies that may not show in routine health checks.

By understanding your unique magnesium needs, you can take proactive steps to optimise energy, support hormonal health, and enhance overall well-being. Pair your results with tailored supplementation for targeted support.

Vitamin D

Vitamin D3 plays a critical role in bone health, immune support, and hormonal balance, yet deficiencies are common, especially in women. Factors such as limited sun exposure, dietary restrictions, and hormonal changes during pregnancy or menopause often exacerbate low levels, leading to fatigue, weakened immunity, and mood disturbances.

Our vegan vitamin D3 blood test offers precise serum analysis, measuring your levels to detect deficiencies that standard checks may miss.

With accurate insights into your vitamin D status, you can take targeted steps to support bone health, immunity, and hormonal function. Pair your results with our vegan D3 supplement for optimal care.

Omega

Omega-3 is essential for brain health, heart function, and hormonal balance, making it particularly important for women. While omega-6 and omega-9 are vital, they are more easily obtained through diet, whereas omega-3 deficiencies are common, especially among women following plant-based diets or during pregnancy and menopause.

Our omega-3 blood test measures levels of EPA and DHA, providing precise insights into your fatty acid balance and helping identify deficiencies that may impact cognitive function, cardiovascular health, and hormonal regulation.

By understanding your omega-3 status, you can take targeted action to optimise well-being. Pair your results with our vegan omega supplement for tailored support.

Ferritin

Ferritin testing measures your stored iron levels, offering vital insights into energy, immune function, and general health. Women, especially those of darker complexions, are more likely to experience deficiencies due to menstruation, pregnancy, or diet, often resulting in fatigue, hair thinning, or reduced vitality.

Our ferritin blood test provides a detailed analysis to help identify and address potential deficiencies early, supporting better long-term health outcomes.

With your results, you can consult our nutritionist for guidance on dietary and lifestyle adjustments that may help improve your ferritin levels and overall wellness.
