Can I take Ashwagandha and Vitamin B complex together?

It is usually safe to take ashwagandha and vitamin B complex together.

Ashwagandha is an adaptogenic herb that helps the body manage stress, while Vitamin B complex supports energy metabolism and nervous system function.

They work through different pathways in the body and do not interfere with how the other is absorbed, broken down, or used.

How to take ashwagandha and vitamin B complex safely

• Always follow the dosage instructions on the product labels.

• If you have an underlying medical condition (such as a thyroid disorder or autoimmune disease), speak with your GP or a pharmacist before starting ashwagandha.

Pregnancy

Do not use ashwagandha during pregnancy as it could cause a miscarriage.

Autoimmune diseases

Ashwagandha can stimulate the immune system, which may worsen the symptoms of autoimmune conditions such as lupus, rheumatoid arthritis, and MS.

Hyperthyroidism (overactive thyroid)

Ashwagandha can increase thyroid hormone levels. You must avoid it if you have an overactive thyroid, as it may worsen your condition or interfere with thyroid medications.

Scheduled Surgery

Stop taking ashwagandha at least 2 weeks before surgery; it can slow down the central nervous system and may dangerously increase the effect of anaesthesia.

Alcohol

It is best to avoid or strictly limit alcohol while taking ashwagandha as it has sedative properties and may enhance the effects of alcohol.

Combining them can lead to excessive drowsiness, impaired coordination, and slowed reaction times.

Dairy products

While dairy is a good source of B vitamins, taking a B complex supplement with a very large amount of dairy may slightly alter the absorption rate of Riboflavin (B2).

However, for most people, taking them together is acceptable unless specified by a doctor.
