Frequently Asked Questions

Why Liquid Supplements?
Liquid supplements are easier to take, fast-absorbing, and allow flexible dosing. Your body doesn’t have to break down a pill first, so the nutrients are available more quickly.
Why do I have to shake it?
Natural ingredients can settle at the bottom. A quick shake mixes everything evenly so you get the intended balance in each serving.
Why does it taste like vitamins and herbs?
That natural taste comes from real vitamins, minerals, and herbs not artificial fillers or heavy flavor masking. What you’re tasting is the function at work.
Why does the color look different?
We don’t use artificial dyes. The color comes directly from the raw nutrients and herbs, so it may look earthy or vary slightly from batch to batch.
Why do I need to refrigerate after opening?
Once opened, refrigerating helps keep the formula fresh and potent. For best quality, use within 60 days of opening.
