Many cancer survivors, after completing chemotherapy or head and neck radiotherapy, often find themselves wondering:
“The treatment is over, so why does everything I eat still taste off, bland, or even metallic — and why can’t I smell things properly anymore?”
Folic Acid (also known as Vitamin B9) is an indispensable nutrient in cancer treatment courses. It plays a core role in red blood cell production, DNA synthesis, and cell repair. During chemotherapy or radiotherapy, folic acid consumption is extremely high, and deficiency directly exacerbates anaemia, fatigue, and oral mucosal damage.
Many patients develop severe folic acid insufficiency due to treatment-induced intestinal absorption impairment, loss of appetite, and vomiting, which reduces treatment tolerance.
Folic acid is not an “anti-cancer vitamin” but serves as supportive care, helping patients maintain stable blood counts, energy supply, and mucosal repair under high-intensity treatment, allowing them to proceed more steadily and smoothly.
Helping you understand “how selenium can help maintain your immunity and antioxidant protection during treatment”
Selenium is an essential trace mineral that plays a critical role in cancer supportive care, as it is a key component of antioxidant enzymes (such as glutathione peroxidase), helping to reduce treatment-induced oxidative stress and inflammation.
Cancer patients often develop selenium deficiency due to treatment consumption and impaired intestinal absorption, leading to weakened immunity, increased fatigue, and greater cellular damage.
Selenium is not an “anti-cancer mineral” but serves as supportive care, helping patients better endure the burden of chemotherapy, radiotherapy, or targeted therapy, maintain tolerance, and improve overall quality of life.
In cancer supportive care, chemotherapy, radiotherapy, and targeted therapies target the tumour but also bring oxidative stress, chronic inflammation, neurotoxicity, and immune suppression, often leaving patients feeling fatigued, in pain, and with reduced tolerance.
Natural compounds (such as curcumin, quercetin, EGCG, resveratrol, alpha-lipoic acid, Reishi polysaccharides, etc.) play an increasingly important role in the adjunctive phase.
They not only help clear free radicals and reduce oxidative damage but also act from multiple angles — anti-inflammation, neuroprotection, immune modulation, and energy support — allowing patients to better endure the burden of treatment, maintain strength, and improve quality of life.
Alpha-Lipoic Acid (ALA) is a powerful antioxidant naturally produced in the body, and it is unique in being both water- and fat-soluble, allowing it to work effectively inside and outside cells. In cancer treatment courses, alpha-lipoic acid is increasingly recognized as a valuable supportive option. It not only directly neutralises free radicals and reactive oxygen species generated during treatment but also regenerates other antioxidants such as vitamin C, vitamin E, and glutathione, forming a robust antioxidant network. This distinctive property enables it to help patients reduce various side effects during chemotherapy, radiotherapy, or targeted therapy, while maintaining better stamina, nerve function, and overall tolerance, allowing the treatment journey to proceed more steadily and smoothly.
Systemic inflammation is a common issue in cancer treatment, often leading to fatigue, pain, reduced tolerance, and lower overall quality of life.
The RGCC Onconomics Plus® test analyzes tumour cells’ real response to over 30 natural substances, including their anti-inflammatory and systemic inflammation-suppressing effects.
Below are several natural substances commonly appearing in RGCC Onconomics Plus® reports with strong anti-inflammatory potential. Each has distinct efficacy and supportive mechanisms, helping you understand their potential value in cancer supportive care.
Helping you understand “how quercetin can gently support your treatment journey”
Quercetin, a natural flavonoid widely found in onions, apples, green tea, and red wine, has attracted increasing attention in cancer supportive care and adjunctive therapy.
It is not an “anti-cancer drug”, but rather a supportive option that helps reduce treatment side effects, boost immunity, and improve tolerance, allowing patients to better endure the burden during chemotherapy, radiotherapy, or targeted therapy while maintaining a higher quality of life.
Quercetin’s effects primarily stem from its strong antioxidant, anti-inflammatory, and anti-tumour properties, with clinical studies indicating it can offer gentle benefits for cancer patients.
Helping you understand “why you always feel drained during treatment” — and gentle ways to improve
During cancer treatment — chemotherapy, radiotherapy, or targeted therapy — the body consumes large amounts of energy and nutrients, leaving patients frequently feeling “no matter how much I sleep, I’m still exhausted”, “always low on energy”, and “my immunity is weak”.
The B vitamins (including B1, B2, B3, B5, B6, B7, B9, B12) are core co-factors in energy metabolism and the immune system.
They participate in the conversion of carbohydrates, fats, and proteins; mitochondrial energy production; nerve conduction; and red blood cell formation.
Deficiency directly exacerbates fatigue, brain fog, anaemia, and immune suppression, reducing treatment tolerance.
Helping you understand “how these antioxidants can truly support your treatment”
During cancer treatment, chemotherapy, radiotherapy, and targeted therapy target the tumour but also generate large amounts of free radicals and reactive oxygen species, causing damage to normal cells, fatigue, neurotoxicity, and immune suppression.
Natural antioxidants (such as vitamin C, glutathione, alpha-lipoic acid, curcumin, Reishi polysaccharides, quercetin, etc.) play a key role in supportive therapy.
They not only quickly neutralise free radicals and reactive oxygen species produced during treatment but also act from multiple angles — cellular energy, neuroprotection, inflammation regulation, and immune balance — helping the body stay as stable as possible under high-intensity treatment, allowing patients to endure side effects with more strength, maintain tolerance, and improve overall quality of life.
Helping you understand “how Reishi can gently support your treatment journey”
Reishi mushroom (Ganoderma lucidum), a traditional Chinese medicinal herb, has gained attention in recent years for its extracts (primarily polysaccharides and triterpenoids) in cancer supportive care.
It is not an “anti-cancer drug”, but rather a supportive option that helps reduce treatment side effects, boost immunity, and improve tolerance, allowing patients to have more strength during chemotherapy, radiotherapy, or targeted therapy.
The effects of Reishi extract mainly stem from its antioxidant, anti-inflammatory, and immunomodulatory properties, with clinical studies showing it can provide gentle benefits for cancer patients.
