How are we different?

Folic acid does not actually occur in nature, strictly speaking. Conventional folic acid, which is still used in many food supplements, is an artificial, synthetic product which cannot be used directly by the body; it must first be converted into folate in order to be bioactive. Critically, this conversion cannot always proceed in the body without issue, as a number of cofactors and enzymes are necessary for it to occur.

Our plant-based folate contains the full spectrum of natural folates from lemon peel, supplying this essential vitamin in the same forms and proportions as found in nature. The natural folates are extracted from the peels of nutrient-rich Indian lemons (grown without the use of plant protection products), ensuring that the natural purity of the raw material are preserved in the nutrient extraction: the folates are dissolved from the lemon peels via a particularly gentle water extraction and are thus guaranteed to be free from further solvents and other chemical additives.

The only other ingredient is premium acacia fibre, cultivated without the use of plant protection products. In contrast to microcrystalline cellulose, a widely used synthetic filler often mixed with nanoparticles, gum arabic is a natural, fibre-rich food. Our fair trade acacia gum is climate neutral and is sustainably cultivated to conserve resources.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.

Vitamin B9: Folate (Folic Acid)

Folate, also known as vitamin B9, is involved in a variety of important body functions. This essential vitamin fulfils numerous important tasks in cell metabolism. It also contributes to the functioning of energy metabolism, can reduce fatigue and tiredness and supports the immune system as well as mental functioning. It is needed for haematosis, cell division, homocysteine metabolism and forming amino acids. Folate also plays a role in the growth of maternal tissue during pregnancy. Folic acid is important for all cell division processes.

Natural, Bioactive Folic Acid: L-Methylfolate from Lemon Peel

The optimal, biologically active form of folate is called L-methylfolate (or, more precisely, L-5-methyltetrahydrofolate, or L-5-MTHF). L-methylfolate is an important methyl donor and an essential component of the methylation cycle.

Many active ingredients are a mixture of L-methylfolate and R-methylfolate, as these two geometric variants occur together in most manufacturing processes. However, R-methylfolate cannot be utilised by the body. Unfortunately, conventional forms of methylfolate can contain up to 50% of this ineffective variant.

Our plant-based folate provides biologically active folic acid from Indian lemon peel, primarily in the form of natural L-methylfolate. This form of folate is characterised by optimal effectiveness and particularly high bioavailability. Found in many different forms in nature, lemon peel provides the full range of active folates.

Health Benefits of Folate (Vitamin B9)

According to the European Food Safety Authority (EFSA), folate contributes to:

  • The growth of maternal tissue during pregnancy
  • Normal amino acid synthesis
  • Normal haematosis
  • Normal homocysteine metabolism
  • Normal mental function
  • Normal functioning of the immune system
  • Reducing tiredness and fatigue
  • Cell division


Recommended Dosage

Take 1 capsule daily (400µg folate) with 200ml water one hour before a meal.

Daily Requirements

According to European authorities, the official daily folic acid requirement for adults is 200µg. The German Nutrition Society (DGE), however, recommends a daily average of 300µg for adults. The DGE notes an increased requirement for individuals who are pregnant (550µg) or breastfeeding (450µg).

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children.


Store in a cool, dry place away from direct sunlight and heat.

All eight essential B vitamins work together. Numerous metabolic processes in the body require them; they can only achieve optimal functionality if each vitamin is in sufficient supply. Therefore, in many cases, it makes sense to supplement these vitamins together.
