    Vitamin C Absorption

    Why Absorption Is Key

    Vitamins only work if your body can absorb them. The more you absorb, the more beneficial they are for you. So no matter how many mg's the bottle has listed, unless the nutrients are highly bioavailable, you're probably not reaping all their benefits. 2by4 Nutristack liquid vitamins are the most bioavailable, fast-acting supplements available.


    1 teaspoon = As much Vitamin C as 20 Oranges

    How to Use

    Take 2x4 Liposomal Vitamin C on an empty stomach for maximum absorption. Perfect for first thing in the morning alongside your morning coffee, smoothie, tea.

    Pour it. Sip it. Feel Amazing.

    Preventative Measures

    Me and my boys are very excited about this product. It is our #1 preventive measure to avoid getting sick other than staying at home and wearing a mask.

    I've been looking for a good quality vitamin C for what seems like forever. I like the fact that there’s no capsules and it’s easy to add to anything. I also like the fact that you get a decent amount of product for your money.

    Help me through Covid

    I recently had the virus. It’s good that I have been taking this liposomal Vit C a month prior. I increased my dose to 4000 mg / day for a week during that time, and I believe my symptoms slowly became mild because of your Vit C. Thanks to your brand 2by4.
