Drug Interaction Concerns: Yikukan EX vs. Vitamin B Complex and Herbal Remedies - Pharmacology

Share to:

Medication consultation


Hello Dr.
Huang: I would like to ask if there are any interactions between the dietary supplement Yigukan EX and the Japanese Koden Kōri Vitamin B complex.
Additionally, are there any potential interactions with traditional Chinese medicine (for bone health and energy replenishment)? Thank you!

Li, 20~29 year old female. Ask Date: 2020/04/12

Dr. Huang Shenggang reply Pharmacology


Hello, Ms.
Li: Thank you for your inquiry.
Upon checking, Yigukang EX contains eight herbal extracts (Astragalus, Salvia miltiorrhiza, Rhodiola rosea, Polygonatum, Red dates, Licorice, Equisetum, and Sargentodoxa cuneata) and four vitamins (B12, C, D, and E).
Additionally, the Mi Tian He Li Ta Vitamin B complex includes B1, B6, B12, E, and calcium.
Since there is overlap in the B vitamins between these two products, it is not recommended to use them concurrently.
Thank you.

More Info


When considering the potential interactions between Yikukan EX, a herbal supplement, and Vitamin B Complex, as well as other herbal remedies, it is essential to understand the components of these products and how they may affect each other.

Yikukan EX is a blend of various herbal ingredients, including Astragalus, Salvia, Rhodiola, and others, which are traditionally used in Chinese medicine to boost energy and support overall health. On the other hand, Vitamin B Complex typically includes a range of B vitamins such as B1, B6, B12, and others, which play crucial roles in energy metabolism, neurological function, and red blood cell production.

From the information provided, there is no documented interaction between Yikukan EX and Vitamin B Complex. However, it is important to note that both products may contain overlapping ingredients, particularly in the B vitamins. While this overlap does not necessarily lead to adverse effects, it is generally advisable to avoid taking multiple supplements with the same active ingredients to prevent excessive intake.

When considering herbal remedies, such as those aimed at bone health or energy replenishment, it is crucial to evaluate their specific ingredients. Many herbal supplements can interact with each other or with pharmaceutical medications, potentially altering their effectiveness or leading to side effects. For instance, some herbs may have blood-thinning properties, while others might affect liver enzymes responsible for drug metabolism.

In your case, if you are taking Yikukan EX alongside a Vitamin B Complex and other herbal remedies, it is wise to consult with a healthcare professional, such as a physician or a licensed herbalist. They can provide personalized advice based on your health status, any underlying conditions, and the specific formulations of the products you are using.

Additionally, it is essential to consider the timing of when you take these supplements. For instance, taking them at different times of the day may help minimize any potential interactions. Moreover, maintaining a balanced diet rich in vitamins and minerals can often provide the necessary nutrients without the need for excessive supplementation.

In summary, while there is no immediate concern regarding the interaction between Yikukan EX and Vitamin B Complex, it is always prudent to approach supplementation with caution. Consulting with a healthcare provider can help ensure that your regimen is safe and effective, particularly when combining multiple supplements and herbal remedies. This approach not only helps in avoiding potential interactions but also supports your overall health and wellness goals.
