How to take

Herbalist tips

Now featuring a bioactive plant-based source of iron from Curry
Leaf. Our Iron Tonic has been reformulated to include a naturally
occurring, plant-derived form of iron sourced from Curry Leaf. This provides gentle, bioactive support for maintaining healthy iron levels, making it an ideal option for individuals seeking a more
natural approach to iron supplementation.

Supports:

• Healthy iron status
• Energy production and vitality
• Gentle daily mineral support

Take your dose with a snack or meal that includes Vitamin C such as kiwifruit, citrus fruits, broccoli or tomatoes. Vitamin C helps iron absorption.

Best to avoid coffee, caffeinated drinks and foods high in calcium such as dairy products for at least an hour after taking Iron Tonic - these are iron inhibitors.

Phytates in raw beans, seeds and grains as well as raw legumes such as chickpeas can also inhibit iron absorption. Cook these ones before eating.


Monitor your iron levels closely if you're following a vegan diet or getting all your iron from plants - it's more difficult for your body to absorb iron solely from plant sources.

This is an original Malcolm Harker tonic. Malcolm recommended:

  • taking this tonic straight, or added to 50 ml of boiled water as a tea
  • avoiding mucus forming foods such as gluten, egg-white, chocolate, dairy, polyunsaturated oils and regular table salt
  • adopting gluten-free grain foods, whole foods (greens, fruits nuts, seeds), unprocessed coconut oil and Celtic & NZ Sea Salt with Kelp

    With all his tonics, Malcolm Harker recommended using Intestinal Cleanse for 1-2 weeks to reduce parasite populations. By reducing the load on the body of parasites, the body is able to use nutrients from food and the active ingredients in his tonics more efficiently.

Benefits

Iron is an essential mineral that is required to help transport oxygen around the body. It is a key component of haemoglobin, a protein found in red blood cells that binds to oxygen in the lungs and carries it to tissues and organs around the body. Without enough iron, the body can't produce enough haemoglobin, leading to fatigue, weakness and decreased oxygen delivered around the body.

Iron is also involved in producing adenosine triphosphate (ATP), the primary energy currency in cells. Iron-containing enzymes play a crucial role in ATP synthesis, which is essential for various cellular processes, including metabolism and enery production.

Iron is required for the synthesis and repair of DNA and also plays a role in immune function by supporting the growth and activity of immune cells.

Iron Tonic combines blackberry concentrate with mineral-rich botanicals including horsetail, oat straw, yellow dock, kelp and Irish moss, alongside ginger and licorice. The blend provides a traditional liquid format for people looking to complement everyday nutritional and iron-focused routines without tablets or capsules.

Not to be taken while pregnant or breastfeeding.

Always read the label and use only as directed. If taking prescribed medication, consult your health professional before taking this product. If symptoms persist, seek professional medical advice.

Iron

Iron

Iron amino acid chelate glycinate

Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen from the lungs around the body. Insufficient healthy red blood cells means your body can’t get enough oxygen which can affect energy levels, brain function and immunity. The body’s requirement for iron more than doubles during pregnancy. The chelated form of iron we use is non-constipating.

Licorice

Licorice

Glycyrrhiza glabra

One of the most widely used and trusted herbs in traditional medicine, licorice is also available in Germany as an over-the-counter medicine. It contains glycyrrhizin, reported to have anti-inflammatory and antimicrobial activities as well as being up to 50 times sweeter than cane sugar. It is also reported to promote a healthy adrenal response to stress. Used for respiratory infections, digestion and healthy mood.

Yellow Dock

Yellow Dock

Rumex crispus

The anthraquinones in yellow dock have mild laxative effects, promoting bowel movements. Research has also shown yellow dock stimulates bile production, supporting liver function and digestion. Bile is essential for digesting fats and detoxifying the liver, and improved bile flow can enhance digestion and nutrient absorption. Yellow dock is considered a blood purifier in traditional medicine. By supporting liver detoxification and enhancing elimination of waste through the bowels, it helps to cleanse the blood of toxins and waste products.
