Bio C® 1000


Gentle on the stomach, Blackmores Bio C®1000 reduces the severity and duration of common cold symptoms.

Why use

With over 200 viruses that can cause the common cold it’s hard to avoid catching a cold. Adults can experience an average of 2-4 colds a year.

The immune system is the body’s natural defence mechanism against germs, a healthy lifestyle is a good way to support your immune system.

Vitamin C is referred to as an essential nutrient because the body cannot make it or extensively store it and must be obtained from food.

Vitamin C helps reduce the severity and duration of common cold symptoms due to its ability to support a healthy immune function.
It is an antioxidant and helps reduce free radicals formed in the body.

To relieve tiredness and help you recover from illness why not try Blackmores Immune + Recovery

The Blackmores difference

Blackmores Bio C® 1000 is buffered with mineral ascorbates making it gentler on the stomach compared to ascorbic acid alone and contains rosehips and acerola which are sources of vitamin C.

A high potency one-a-day dose of vitamin C to help reduce the severity and duration of common cold symptoms.

Blackmores Bio C® 1000 contains no added preservatives or artificial flavours or sweeteners.

Hello, Is it the same Bio Vitamin C 1000 mg, which provides antioxidant support, supports immune system and with citrus bioflavonoids and rosehips? Kindly Confirm I need to order for myself. If not, then which one is that? Thanks Rachit
Hello. I'm wondering if this product can improve my skin concern like dull skin?
Hi, Is it safe during pregnancy?
The picture shows 150 low acid tablets 1000mg. The actual purchase is not what the picture shows. The purchase is for 62 tablets at $21.99. I would have liked to buy the larger size. I really think this is false advertising. With my last order, I found the same problem. I believed that I had ordered the larger size however I only received the smaller size. I think this problem needs to be addressed. (I have been buying your products for over 40 years). Regards Jenny
