Indications & Clinical Uses

Oligosol provides selenium, a trace element involved in antioxidant and thyroid pathways.

  • Selenium deficiency: helps restore normal selenium levels in individuals with inadequate dietary intake.
  • Oxidative stress: supports activity of antioxidant enzymes such as glutathione peroxidase.
  • Thyroid function: contributes to the conversion of thyroid hormones by providing necessary cofactor.

How It Works

  • Sodium selenite is reduced intracellularly to selenide, which is incorporated as selenocysteine during translation of selenoproteins. These selenoproteins—including glutathione peroxidases, thioredoxin reductases and iodothyronine deiodinases—play essential roles in antioxidant defense, redox regulation and thyroid hormone metabolism, thereby supporting cellular protection and endocrine balance.

Side Effects

Sodium selenite may cause adverse reactions, which are generally dose‑dependent.

Common Side Effects

  • Nausea: mild gastrointestinal upset.
  • Metallic taste: transient oral sensation.
  • Diarrhea: loose stools.
  • Headache: mild cranial discomfort.

Serious or Rare Side Effects

  • Selenosis: chronic excess leading to hair loss, nail brittleness, and skin lesions.
  • Allergic reaction: rash, itching, or swelling.
  • Severe gastrointestinal irritation: vomiting, abdominal pain.

Precautions & Warnings

When using Oligosol, consider the following precautions to ensure safe administration.

  • Dosage adjustment: tailor dose based on individual selenium status and dietary intake.
  • Renal impairment: monitor because reduced clearance may increase exposure.
  • Pregnancy and lactation: use only if benefits outweigh potential risks.
  • Concurrent antioxidant therapy: assess for possible additive effects.
  • Avoid excessive intake: do not exceed recommended dietary allowance without medical supervision.
  • Store at ambient temperature: keep below 25 °C, protect from moisture and direct sunlight.

Avoid Interactions

Sodium selenite can interact with certain medicines and nutrients.

Major Interactions (Avoid)

  • Anticoagulants (e.g., warfarin): selenium may potentiate anticoagulant effect, increasing bleeding risk.
  • Chemotherapy agents (e.g., cisplatin): high selenium may interfere with drug efficacy.

Moderate Interactions (Monitor Closely)

  • Vitamin C: high doses may reduce selenium absorption.
  • Zinc supplements: competitive absorption may alter selenium status.
  • Thyroid hormone replacement (levothyroxine): selenium can affect hormone conversion, requiring monitoring.

Frequently Asked Questions

Oligosol is a nutritional supplement that provides the trace element selenium. It is used to correct selenium deficiency, support antioxidant enzyme activity, and aid normal thyroid hormone metabolism in the general population.

Sodium selenite is converted to selenide inside cells, which is then incorporated into selenocysteine during the synthesis of selenoproteins. These proteins, such as glutathione peroxidase and iodothyronine deiodinases, protect cells from oxidative damage and help convert thyroid hormones to their active forms.

The appropriate dose of Oligosol is determined by a qualified health professional based on individual selenium status, dietary intake, age and health condition. The prescriber will set the exact amount and frequency for each patient.

Safety in pregnancy and lactation has not been fully established. Oligosol should only be used if a health professional judges that the potential benefit outweighs any possible risk to the mother or infant.

To place an order, submit an enquiry on the Oligosol product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Oligosol delivers selenium as sodium selenite, an inorganic form that is readily reduced to active selenide. Other supplements may use organic forms such as selenomethionine. Inorganic selenium is often chosen for its predictable conversion to selenoproteins, while organic forms may have different absorption characteristics.

Store Oligosol at ambient temperature, preferably below 25 °C. Keep the product in its original container, protect it from moisture, direct sunlight and extreme heat to maintain stability and potency.

Oligosol is intended for oral or sublingual administration. The product is typically taken with water, following the dosage instructions provided by the prescribing health professional.

The most serious risks include selenosis from chronic excess intake, which can cause hair loss, nail brittleness, skin lesions, and severe gastrointestinal irritation. Allergic reactions such as rash, itching or swelling may also occur and require immediate medical attention.

Individuals with known hypersensitivity to selenium or any component of the formulation should avoid Oligosol. Patients with uncontrolled thyroid disease, severe renal impairment, or those already receiving high‑dose selenium from other sources should consult a health professional before use.
