Tanakan is a standardized extract of Ginkgo biloba (specifically known as EGb 761) used primarily to improve peripheral and cerebral blood flow. The standard adult dosage typically involves taking a 40 mg tablet three times daily with meals, though therapeutic regimens can range up to 120 mg to 240 mg per day depending on the specific condition treated. Because it affects platelet aggregation and interacts with common prescription drugs like anticoagulants, understanding proper administration and safety boundaries is vital before starting treatment.
This medication contains strict phytochemical ratios—typically 22% to 27% flavonoid glycosides and 5.4% to 6.6% terpene lactones—which differentiate pharmaceutical-grade extracts from standard over-the-counter herbal teas or unstandardized powders. Below, we break down precise usage protocols, real-world safety considerations, and common pitfalls to avoid.
Standard Dosage and Administration Rules
Getting the dosage right depends entirely on the formulation strength and the clinical objective. Most commercial versions of Tanakan are supplied as 40 mg film-coated oral tablets.
- Standard Adult Regimen: One 40 mg tablet taken three times daily (morning, afternoon, and evening).
- Administration Tip: Swallow the tablets whole with a half-glass of water, ideally during or immediately after meals to minimize potential mild gastrointestinal upset.
- Higher Therapeutic Dosing: In clinical evaluations for peripheral arterial disease or severe cognitive decline, physicians sometimes scale total daily intake up to 120 mg or 240 mg, divided into two or three smaller doses to maintain steady plasma concentrations. Never increase your intake independently.
Consistent daily timing matters. If you miss a dose, take it as soon as you remember, unless it's almost time for your next scheduled pill. Don't double up doses to make up for a missed one.
Primary Therapeutic Uses
Medical providers prescribe or recommend standardized Ginkgo biloba extracts like Tanakan for specific vascular and neurological indications where microcirculation needs support.
- Cerebral Insufficiency: Used to address age-related cognitive deficits, including mild to moderate memory impairment, lack of concentration, and vertigo.
- Peripheral Arterial Disease: Helps mitigate intermittent claudication—pain or cramping in the legs during walking caused by narrowed arteries—by improving blood flow to the extremities.
- Tinnitus: Occasionally deployed as a supportive intervention for inner-ear disturbances such as ringing in the ears when linked to vascular issues.

Side Effects and Tolerability
Most individuals tolerate standard doses well, but adverse reactions can still occur. When side effects manifest, they're typically mild and transient.
- Digestive Discomfort: Mild nausea, abdominal discomfort, or diarrhea can happen, especially if the tablets are taken on an empty stomach.
- Neurological Signs: Occasional headaches or dizziness have been reported during the initial weeks of therapy.
- Dermatological Reactions: Hypersensitivity skin rashes, itching, or localized allergic inflammation occur rarely in sensitive users.
If persistent physical discomfort arises, discontinue use and consult a clinical professional or reference safe drug administration data via MedlinePlus.
Critical Precautions and Drug Interactions
Tanakan is a biologically active substance that alters how blood flows and how the liver processes certain compounds. Ignoring its pharmacological properties can lead to severe complications.
- Bleeding Risks: Because Ginkgo biloba inhibits platelet-activating factor, it increases the risk of bleeding. It interacts negatively with anticoagulants like warfarin or anti-platelet drugs like aspirin and clopidogrel. Always stop usage prior to scheduled surgeries.
- Metabolic Contradictions: Concomitant use with certain antiretrovirals (such as efavirenz) is discouraged due to potential drops in therapeutic drug efficacy.
- Excipient Warnings: Tanakan tablets often contain lactose monohydrate. Patients with rare hereditary problems of galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption should avoid this product.
- Pregnancy and Lactation: Safety during pregnancy hasn't been established, and it's contraindicated for expecting or breastfeeding mothers.
Frequently Asked Questions
Can I take Tanakan with my daily aspirin?
Combining Tanakan with aspirin or other non-steroidal anti-inflammatory drugs increases your risk of bruising and bleeding. You should consult a physician before combining anti-platelet therapies with ginkgo extracts.
How long does it take to notice results?
Clinical improvements aren't instantaneous. Most vascular and cognitive studies observe measurable changes only after 4 to 12 weeks of continuous, uninterrupted daily supplementation.
Should I take it on an empty stomach?
No. Taking Tanakan with meals helps reduce the likelihood of stomach upset and improves overall gastrointestinal tolerance.
Is Tanakan the same as raw ginkgo leaf supplements?
No. Tanakan is a pharmaceutical-grade, standardized extract (EGb 761) with tightly controlled active ingredient ratios. Raw leaf powders lack this precise standardization and may contain higher levels of toxic ginkgolic acids.
