1. Clinical Overview
A fixed-dose combination supplement containing micronized Dehydroepiandrosterone (DHEA), a high-dose of Folic Acid, and a high-dose of Vitamin D3 (Cholecalciferol). This combination is primarily indicated for the management of age-related decline in DHEA levels, particularly in postmenopausal women and older men, with adjunctive support for bone health, cardiovascular health, and mood. The micronization of DHEA enhances its bioavailability. The high doses of folic acid and vitamin D3 are tailored for therapeutic correction of deficiencies and specific clinical endpoints, not general supplementation.
| Onset | Duration | Bioavailability |
|---|---|---|
| DHEA: Hormonal effects may be observed within 2-4 weeks. Folic Acid: Biochemical correction of homocysteine levels can begin within days. Vitamin D3: Serum 25(OH)D levels begin to rise within days, but clinical effects on bone may take months. | DHEA: 24-48 hours due to its conversion to active androgens/estrogens. Folic Acid: Dependent on body stores; regular dosing required. Vitamin D3: Long half-life in the body (weeks). | DHEA (Micronized): ~70-80% (oral). Folic Acid: ~85-100% (oral, on an empty stomach). Vitamin D3: ~60-90% (oral, with a fatty meal). |
2. Mechanism of Action
DHEA serves as a precursor for the synthesis of androgens (testosterone, dihydrotestosterone) and estrogens (estradiol, estrone) in peripheral tissues, exerting sex steroid-like effects. Folic Acid acts as a cofactor in one-carbon transfer reactions crucial for DNA synthesis, repair, and methylation, and for homocysteine remethylation to methionine. Vitamin D3 is converted to calcitriol, which binds to the Vitamin D Receptor (VDR), regulating gene expression for calcium/phosphate homeostasis, cell proliferation, differentiation, and immune modulation.
3. Indications & Uses
- Management of age-related decline in DHEA levels (Adrenopause) in individuals >40 years
- Adjunctive therapy for osteoporosis prevention and management in postmenopausal women and older men with concurrent DHEA and Vitamin D deficiency
- Supportive therapy in individuals with high homocysteine levels (Hyperhomocysteinemia) for cardiovascular risk reduction
4. Dosage & Administration
Adult Dosage: One tablet daily, preferably in the morning with food (especially a meal containing fat to enhance Vitamin D3 absorption). Duration as prescribed by physician, typically for 3-6 months initially, followed by re-assessment.
Administration: Take with a meal, preferably breakfast, containing some dietary fat. Swallow whole with a glass of water. Do not crush or chew. Avoid taking with high-fiber meals or bran, which can reduce folic acid absorption.
5. Side Effects
Common side effects may include:
- Mild gastrointestinal upset (nausea, bloating)
- Headache
- Acne or oily skin (DHEA effect)
- Mild hair loss or increased facial/body hair in women (androgenic effects of DHEA)
- Insomnia or restlessness (if taken late in the day)
6. Drug Interactions
| Drug | Effect | Severity |
|---|---|---|
| Antiepileptics (Phenytoin, Carbamazepine, Phenobarbital, Valproate) | Reduce serum folate levels; may decrease efficacy of antiepileptics or increase seizure risk. | Major |
| Methotrexate | Folic acid may reduce the efficacy of methotrexate in cancer chemotherapy (but can be used to reduce toxicity in rheumatoid arthritis treatment). | Major |
| 5-Fluorouracil (5-FU) | Folic acid (as leucovorin) is used to enhance 5-FU toxicity in cancer therapy; unsupervised use may alter effects. | Major |
| Tamoxifen, Aromatase Inhibitors | DHEA may counteract the estrogen-suppressing effects of these breast cancer therapies. | Contraindicated |
| Testosterone, Anabolic Steroids | Additive androgenic effects with DHEA, increasing risk of side effects. | Major |
| Thiazide Diuretics (e.g., Hydrochlorothiazide) | May increase risk of hypercalcemia by reducing calcium excretion. | Moderate |
| Corticosteroids (e.g., Prednisone) | May antagonize Vitamin D3 effects on calcium absorption and increase calcium excretion. | Moderate |
| Orlistat, Bile Acid Sequestrants (Cholestyramine) | May reduce absorption of fat-soluble Vitamin D3. | Moderate |
| Trimethoprim, Pyrimethamine | Antifolate drugs; may antagonize folic acid effects. | Moderate |
7. Patient Counselling
- DO take exactly as prescribed, once daily with a meal containing fat.
- DO inform all your doctors and pharmacists you are taking this supplement, especially before surgery or new prescriptions.
- DO attend regular follow-ups for blood tests (hormone levels, calcium, kidney/liver function, PSA if male).
- DONT take if you are pregnant, planning pregnancy, or breastfeeding.
- DONT share this medication with others, even if they have similar symptoms.
- DONT take additional vitamin D, calcium, or folic acid supplements unless advised by your doctor.
- DONT stop taking abruptly if on long-term therapy; consult your doctor.
8. Toxicology & Storage
Overdose: Acute overdose unlikely to be life-threatening from a single tablet. Chronic excessive intake can lead to: DHEA: Androgenic effects in women (hirsutism, acne, voice deepening), gynecomastia in men, hepatotoxicity. Folic Acid: Can mask neurological progression of B12 deficiency. Vitamin D3: Hypervitaminosis D leading to hypercalcemia: nausea, vomiting, anorexia, polyuria, polydipsia, weakness, nervousness, pruritus, renal failure, vascular calcification.
Storage: Store in a cool, dry place, below 30°C. Protect from light and moisture. Keep the bottle tightly closed. Keep out of reach and sight of children. Do not use after the expiry date printed on the packaging.
