Liquid Vitamin C (ascorbic acid) in low-dose, clean formulation. Designed for people whose bodies don’t tolerate the mega-dose Vitamin C products that dominate the supplement industry — and whose sensitive stomachs need a gentler approach.
What Vitamin C Does
Vitamin C is one of the most important water-soluble vitamins in the body. It functions as a powerful antioxidant, supports immune function, plays a key role in collagen synthesis (essential for skin, joints, wound healing, and blood vessel integrity), and helps the body absorb iron from plant-based foods. Unlike many animals, humans can’t produce their own Vitamin C, so we have to get it from food or supplementation.
Why Ascorbic Acid
We use ascorbic acid — the standard, well-studied form of Vitamin C. Most clinical research on Vitamin C is done with ascorbic acid, and it’s what your body absorbs and uses naturally. We’ve chosen it because it works, not because it markets well.
Why Low-Dose Liquid
Most “premium” Vitamin C supplements run 1,000 to 5,000 mg per serving — 1,100% to 5,500% of the daily value. The thinking is “more is better.” The reality is different.
First, your body can only absorb so much Vitamin C at once. Research shows absorption drops dramatically above about 200 mg per dose. Anything above that is largely excreted, not used.
Second, high-dose ascorbic acid (especially above 1,000 mg/day) commonly causes digestive upset, diarrhea, and stomach irritation — particularly in sensitive systems. For people with already-sensitive digestion, mega-dose Vitamin C is a trigger, not a benefit.
We keep ours at 500% DV or less, in a liquid format that lets you adjust your dose drop by drop. The result is a Vitamin C that supports immune and antioxidant function without overwhelming your digestive system.
Common Uses
People commonly use Vitamin C for:
– Supporting immune function (especially during seasonal changes)
– Antioxidant support and free radical defense
– Supporting collagen production for skin, joints, and connective tissue
– Supporting iron absorption from plant foods
– Supporting recovery from physical or mental stress
Often Paired With
– Vitamin E for synergistic antioxidant support
– Vitamin K for bone and cardiovascular support
– Liquid B-Complex for daily energy and nervous system support
