How to combine supplements safely? When is it advisable to get blood tests?

Introduction
Our catalogue includes a wide range of supplements: to support immunity, improve concentration, aid restful sleep, care for skin, or boost overall wellbeing. With so many options, a common question arises: Can I take several supplements at the same time? This article helps you decide.

  1. Formulas designed with your safety in mind
    All our supplements are formulated to be complementary and safe when used together. We avoid duplicating nutrients at excessive doses across different products, which helps reduce the risk of vitamin or mineral overload when used sensibly.

However, that doesn’t mean every combination suits everyone. Each body is different: we have different needs, deficiencies and lifestyles. Ideally, get lab tests to understand your current nutrient levels and observe how your body responds to supplementation.

  1. Not everything can be measured in a test
    Some nutrients—such as ashwagandha, reishi or lion’s mane—cannot be reliably measured in a standard blood test. In these cases, the best way to evaluate their effects is to notice how you feel: improvements in mood, focus, resistance to infections, sleep quality or energy levels.

Remember: adaptogens and vitamins tend to act gently and gradually. It usually takes several weeks of regular use to feel their full effect.

  1. What’s worth measuring before supplementing?
    To tailor supplementation to your real needs, it’s best to run blood tests (and in some cases urine tests) to identify which nutrients are lacking and by how much.

Some supplements are generally safe at moderate doses even without exact baseline levels, because the body can excrete any excess: vitamin C, biotin, B-vitamins (B1, B2, B3, B5, B9, B12), vitamin E and certain adaptogens.

Other nutrients are commonly low in the population—especially with diets low in fresh foods, higher stress, or intense physical/mental effort: vitamin D, magnesium and several B-vitamins.

Nutrient Recommended test Optimal level / reference values
Vitamin D3 25(OH)D Ideal: 60–80 ng/mL (many labs mark 20–30 ng/mL as “normal”, but that’s a physiological minimum, not ideal)
Magnesium Serum magnesium 0.75–0.95 mmol/L (ideal > 0.85 mmol/L)
Vitamin B6 Blood B6 > 20 nmol/L
Iron & Ferritin Iron, ferritin, FBC Women: 40–150 ng/mL; Men: 50–200 ng/mL

  1. When is it worth getting bloods done?
    Testing is advisable when you:

  • Have persistent symptoms such as fatigue, hair loss, dry skin or muscle aches.

  • Follow a restrictive diet or your eating habits are unbalanced.

  • Are under significant stress or doing intense physical activity.

  • Want to optimise sports or cognitive performance.

Once you have results, it’s important to review them with a health professional to tailor supplementation and avoid potential interactions or overdosing.
