    Vitamin D3 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.


    How to Use

    Take 2x4 Vitamin D in the morning with food to enhance absorption. An amazing addition to a balanced breakfast.

    Pour it. Sip it. Feel Amazing.

    Consistent Excellent

    I have purchased similar products several times for the past couple years. This is the first time where I have noticed the difference in my body within a few weeks. I also noticed the content consistency in every bottle. Definitely will be a regular buyer of this brand.

    Easy Subscription

    I enjoy getting my products every month through the subscription without any hassle! They arrive at my doorstep intact every month or so. I requested my magnesium come more often and now I don’t have to think about staying on track for any of them

    I can tell

    I can definitely tell the difference of when I’m on this supplement or not. I do weight training and I also have very low blood pressure. If I didn’t take it for a few days, I felt sluggish. I’ve tried other brands but this one is by far the best!

    Just Right

    It’s a good product. Right sweetness and smooth taste with no side effects. Pretty much within my budget to maintain my health. I will definitely recommend it to family and friends.
