Product Overview

An essential nutrient to support your immune system, we’ve leveled up our Vitamin C tablets by adding Bioflavonoids and Rose Hips to pack in antioxidants, support optimal immune health, and help reduce inflammation.

Historically known to improve overall health, Vitamin C boosts immunity by supporting white blood cell function.

Added Bioflavonoids from lemon, orange, grapefruit, lime, and tangerine provide an extra dose of potent antioxidants to protect against oxidative stress and support the absorption of Vitamin C.

Lastly, added Rose Hips cover all your bases by packing in additional Vitamin C, flavonoids, and antioxidants to protect your defenses and reduce inflammation.

So go on and get rid of your basic vitamin c tablets and level up with ATH Vitamin C with Bioflavonoids + Rose Hips.

Good product, but...

This is a good product, but very large tablet, which makes it difficult to swallow. Wish it came in a capsule.


Thanks for the feedback Rebecca, I'll take it back to the dev team and see what we can do.

This vitamin is HUGE! But after 3 times of taking it, I got used to it. I like that it's giving me vitamin C, as i don't always want to eat oranges :P It tastes a bit sour, and I think it's a fun way to switch up taking vitamin c, and I add it along with other supplements. This is also my first time taking vitamin C supplement.


Thanks Andrea for adding us to your daily grind!

During these tough times immune support is priority number one! And This Vitamin C is part of my daily regimen of vitamins I take from Ath as it provides a significant source of daily vitamin C.
