A Malcolm Harker original tonic of traditional silica and iron herbs enriched with easily absorbed iron glycinate. Non-constipating and gentle on the digestive system, this tonic has a medicinal flavour and salty after taste. This tonic includes herbs and fruit juices selected to aid absorption and support healthy blood cells. Iron Tonic is useful for all low iron conditions and an effective plant-based option for those following a vegan or vegetarian diet. Not suitable to take while pregnant or breastfeeding.

How to take

Adults over 12 years: take 5-10 mls three to four times daily.

Shake well before use. Swill in the mouth for
10 seconds before swallowing if possible.

Children under 12 years and pregnant or breastfeeding women may take Harker Herbals Iron Boost.

Herbalist tips

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 50ml 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 also 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.

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.

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 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.

Rubus fruticosus
