In this exclusive training for be levels professionals, Cristina Sánchez, an integrative oncologist and educator specializing in health and lifestyle through her digital channels—especially known on Instagram as @loquedigatuoncologa, offers a detailed vision on supplementation for oncology patients, emphasizing that it should not replace conventional treatments, but rather complement them to mitigate side effects and support key systems of the body [06:22]. The most important moments Vitamin D [10:39]: Its importance is highlighted as a hormone related to bone metabolism, cell proliferation, and immune function. The recommended dose is 4000 IU/day in case of deficiency, moving to 1000 IU/day for maintenance, always with caution in cases of hypercalcemia. Be levels' vitamin D is complemented with vitamin K2 to direct calcium to the bone [16:17]. Omega-3 [17:15]: Considered an essential anti-inflammatory, omega-3 helps break the inflammation cascades that promote tumor growth. Given the excess of omega-6 in the modern diet, supplementation is crucial. The recommended therapeutic dose is 1000-3000 mg/day of EPA and DHA, with an emphasis on the quality of the supplement to avoid oxidation and contamination [22:02]. Magnesium [24:26]: Participates in more than 300 biochemical reactions; it is crucial for muscle, nerve, and cardiac function and energy production. It is fundamental in oncology to counteract the loss of muscle mass and insulin resistance. A dose of 300-400 mg/day is recommended, preferably in the form of citrate or bisglycinate. Zinc [31:56]: Essential for immune and liver function, it helps in tissue healing and cell regeneration. Chemotherapy can reduce its levels. The recommended dose is 15-25 mg/day in the form of picolinate, with caution not to exceed this to avoid interfering with copper absorption [35:58]. Melatonin [36:36]: Its crucial role in cell regeneration and repair is highlighted, in addition to its antioxidant and antitumor properties. Usual doses are 1.9 mg to 3 mg for antioxidant effects, and higher doses (6-10 mg) can be given under medical supervision. B-complex vitamins [41:28]: They are water-soluble and unlikely to accumulate. They are vital for energy metabolism, neurological function, and DNA synthesis. B12 is especially important for blood cell formation and in cases of digestive malabsorption common in oncology patients. Antioxidants [47:32]: Caution must be taken during chemotherapy, as some antioxidants can be counterproductive. Vitamin C, selenium, NAC, and coenzyme Q10 are considered beneficial [50:00]. However, vitamin E in high doses, beta-carotene, and curcumin (due to drug interactions) should be used with caution or avoided [51:53]. Important conclusions: Supplementation should always have professional supervision [54:54]. Use must be individualized according to the patient and their treatment [55:24]. Supplements do not replace a balanced diet or a healthy lifestyle [56:07]. It is crucial to be cautious with interactions between supplements and drugs, as well as with high doses [56:37].
