Cordyceps Supplement 21000mg with Black Pepper & Vitamin C

What Cordyceps Research Actually Shows

This product provides a concentrated 10:1 Cordyceps sinensis extract, delivering 2100mg per daily serving (equivalent to 21,000mg of raw cordyceps powder), alongside black pepper extract (studied for a role in improving absorption of various compounds) and vitamin C. As covered in more detail in our medicinal mushroom guide, cordyceps is studied for a possible role in supporting ATP production and oxygen utilisation during exercise, with several genuine human trials exploring measures like VO2 max and exercise performance — results are mixed across studies, making this a promising rather than fully settled area of research.

It’s worth being measured about the immune claim specifically: vitamin C has an established, EU-authorised role in normal immune function, but “strengthening” the immune system through the combination with cordyceps overstates what current research establishes — cordyceps contains compounds studied for immune-modulating properties, which is a genuine area of research interest rather than a guarantee of fewer infections.

Two safety points worth knowing before regular use: cordyceps may affect blood sugar in some research, so if you’re diabetic or take blood sugar medication, it’s worth discussing regular use with your GP, since combining the two could affect glucose control. Because of its immune-modulating properties, anyone with an autoimmune condition or taking immunosuppressant medication should check with their GP before use, rather than assuming general “immune support” framing applies safely to their situation.

Claims about specific benefits for men versus women rest on more limited, preliminary research than the general energy and exercise findings above, and are worth reading as areas of interest rather than established, sex-specific effects.

This formula is manufactured in Europe, vegan, gluten-free, and lactose-free, with lab testing for purity and potency. Take 2 capsules daily with water. Speak to your GP before starting if you have diabetes, an autoimmune condition, take regular medication, or have an existing health condition.
