Heidelberger Chlorella Iron as Iron Bisglycinate Capsules
90 capsules · 1 capsule per day
Product description
This iron supplement combines 15 mg of iron as bisglycinate with 30 mg of vitamin C and glycine. The product character therefore lies in targeted iron supplementation with complementary cofactors rather than in a broad micronutrient blend. From an orthomolecular perspective, iron should generally be used according to need and ideally assessed with laboratory values, because additional iron offers no advantage when status is already adequate.

Product character
This iron supplement combines 15 mg of iron as bisglycinate with 30 mg of vitamin C and glycine. The product character therefore lies in targeted iron supplementation with complementary cofactors rather than in a broad micronutrient blend. From an orthomolecular perspective, iron should generally be used according to need and ideally assessed with laboratory values, because additional iron offers no advantage when status is already adequate. The bisglycinate form is especially relevant as a clearly defined iron compound, while vitamin C meaningfully complements the formula.

Nutrient knowledge & reference values
Nutrient knowledge & reference values
General nutrient information for interpreting the product dosage. Signs of insufficient or excessive intake are non-specific and do not replace a diagnosis.
Vitamin C
Vitamin C (ascorbic acid) is an essential water-soluble vitamin. presents physiological functions, the EU NRV, safety assessment and product-specific dosage separately.
Functions
EU-authorised health-claim functions include, among other things: vitamin C contributes to normal collagen formation for the normal function of blood vessels, bones, cartilage, gums, skin and teeth. It contributes to normal energy-yielding metabolism, normal functioning of the nervous system and immune system, and the protection of cells from oxidative stress. Vitamin C also contributes to the reduction of tiredness and fatigue and increases iron absorption.
Possible signs of insufficient intake
Severe vitamin C deficiency can lead to scurvy. Reported signs include fatigue, inflammation of the gums, pinpoint bleeding, increased capillary fragility and delayed wound healing. Such symptoms are not suitable for self-diagnosis.
Points to consider at high intake
EFSA was unable to derive a UL for vitamin C because of insufficient data. High additional intake can mainly cause gastrointestinal symptoms such as diarrhoea, nausea, bloating or abdominal cramps. With very high amounts, individual risk factors should be taken into account.
Special considerations
An increased risk of inadequate intake exists, among other situations, with a very one-sided diet, malabsorption and in smokers or people with substantial passive-smoke exposure. In haemochromatosis, particular caution is advisable with high-dose vitamin C because it increases non-haem iron absorption.
Interactions / caution
Vitamin C can increase non-haem iron absorption. High-dose supplementation in haemochromatosis should only be used after professional consultation. During chemotherapy or radiotherapy, high-dose antioxidant supplementation should be coordinated with the treating team.
