Vitamin C is one of the most popular supplements on the planet, and for good reasons. But with so many products on the market, from regular vitamin C to liposomal vitamin C, how can you know which one to take, or if you’re absorbing what you’re taking? The short answer is… it depends on the form and amount of vitamin C you’re taking.
ARE YOU GETTING ENOUGH?
Australian research has found that a significant percentage of the population has inadequate vitamin C status. Although Australia has a year-round supply of vitamin C-rich fruit and vegetables, deficiency persists and is largely attributable to inadequate dietary intake rather than impaired absorption.
A recent scoping review concluded that the community prevalence of vitamin C deficiency and inadequacy in Australia is comparable to, and in some subgroups higher than, that reported in other high-income nations, challenging the assumption that scurvy is a disease of the past. Deficiency is consistently linked to diets low in fresh produce, which are more common among people experiencing socioeconomic disadvantage, food insecurity, restrictive or monotonous eating patterns, alcohol intake or tobacco use.
In Australian hospital settings, vitamin C deficiency is surprisingly common and frequently co-exists with protein-energy malnutrition, reflecting poor overall dietary quality in at-risk patients. Because the body cannot synthesise ascorbic acid and stores are depleted within weeks to a few months of insufficient intake, populations relying on highly processed, produce-poor diets remain vulnerable, and clinicians are encouraged to consider dietary history when deficiency is suspected.
WHAT’S THE DIFFERENCE BETWEEN LIPOSOMAL AND REGULAR VITAMIN C?
Whether they’re powders, tablets, chewables or gummies, most vitamin C supplements use ascorbic acid in a free form that is absorbed directly through the gut wall. This might sound great, but our gastrointestinal system has a limited capacity for absorbing ascorbic acid at any one time, meaning that a high proportion of a standard supplement dose of vitamin C is likely to pass through the body unused.
Liposomal vitamin C bioavailability is enhanced because it encases ascorbic acid molecules inside phospholipid ‘bubbles’, which are microscopic structures that closely resemble the body’s own cell membranes. This shell allows the vitamin C to pass through the digestive system largely intact and then deliver it directly to the cells that need it.
HOW DOES THE BODY ABSORB VITAMIN C?
Vitamin C is a water-soluble nutrient, meaning that we don’t store it and it must be replenished from food and supplementation on a daily basis. Once it’s ingested, ascorbic acid is absorbed via specific transporters in the small intestine, but these have a low maximum saturation point.
At lower doses, around 200 mg, absorption rates from free ascorbic acid-based vitamin C supplements can be sufficient. But as dosing increases, absorption decreases, and excess vitamin C is excreted rather than used by the body.
Rather than competing for intestinal transporters, liposomal particles are enveloped by cells in the gut wall directly, meaning that more of the nutrient reaches the bloodstream and, therefore, the tissues and organs that need it. Understanding how the body absorbs vitamin C helps explain why form can determine choice.
IS LIPOSOMAL VITAMIN C ABSORBED WELL?
For anyone who has wondered, “How do I know if I am absorbing my vitamin C?” Studies have shown that liposomal vitamin C raises plasma vitamin C levels more than average ascorbic acid, even when given at the same dose. Other studies have found that liposomal vitamin C supplementation resulted in higher circulating vitamin C concentrations than either ascorbic acid or intravenous forms.
DOES LIPOSOMAL VITAMIN C UPSET THE STOMACH?
Because liposomal vitamin C encases ascorbic acid in a phospholipid shell, it does not make direct contact with the gut lining. It is also more bioavailable and therefore less vitamin C is left in the digestive tract when ingested. Stomach upset is generally caused by undigested vitamin C and so liposomal forms are less likely to cause this when taken at recommended doses.
THE BENEFITS OF LIPOSOMAL VITAMIN C
Liposomal vitamin C benefits reach across many body systems, and is therefore central to health and wellbeing at many levels. In offering a highly bioavailable form of the nutrient, liposomal vitamin C offers meaningful support in many areas, including:
- Immune System Support - Vitamin C helps maintain and support healthy immune system function, contributing to the body’s natural defences and assisting in the response to fight illnesses.
- Collagen, Connective Tissue & Skin Health. In helping to maintain collagen formation, vitamin C supports healthy connective tissue, gum health, healthy teeth, bone health, blood vessel health, and wound healing.
- Antioxidant Protection. Vitamin C helps reduce the free radicals formed in the body which may be increased due to environmental pollution, UV exposure and physical stress.
- Energy Production & Nervous System Function. Vitamin C plays a role in the biosynthesis of carnitine, a compound that converts fatty acids into cellular energy, and in the synthesis of neurotransmitters, helping to maintain energy production, relieve feelings of tiredness and fatigue, and support healthy nervous system function.
Are you confused about which vitamin C to take? The form may make a difference to choice and the research on liposomal technology has demonstrated its effectiveness.
Studies have shown that liposomal vitamin C produces higher plasma concentrations than non-liposomal forms at equivalent doses, meaning more vitamin C is circulating and available to tissues.
Getting more from your vitamin C supplement is less about taking more, and more about choosing the right form.
WHO BENEFITS MOST FROM LIPOSOMAL VITAMIN C?
Liposomal vitamin C is a great choice for anyone seeking a premium form of vitamin C supplement with clinical evidence to back it up. It may be particularly well suited for:
- People with digestive sensitivities who experience discomfort from their usual vitamin C supplements.
- People who have inadequate dietary intake.
- Those focused on skin health, collagen production, or connective tissue support, where consistent, daily, well-absorbed vitamin C is required.
While vitamin C is available from fruits and vegetables like berries, citrus, kiwifruit, capsicum and broccoli, it’s one of the least stable vitamins, sensitive to heat, light, oxygen, and processing. A reliable, highly bioavailable supplement can offer a practical daily vitamin C safety net alongside a balanced diet.
HOW TO CHOOSE A HIGH-QUALITY LIPOSOMAL VITAMIN C
Not all liposomal supplements are created equal. In your search for a quality form of vitamin C supplement, look for:
- Genuine phospholipid liposomal technology (not simply a vitamin C product with added lipids).
- A clinically supported dose of ascorbic acid per serve.
- Clear labelling, third-party testing and transparent manufacturing standards.
- A reputable brand.
Ideally, a qualified practitioner will assist you to meet your individual supplement needs.
IS IT TIME TO MAKE THE SWITCH?
Are you confused about which vitamin C to take? Here’s what the research says… Liposomal technology offers a science-backed solution to the limitations of conventional forms of vitamin C and could be the obvious choice.
After all, getting more from your vitamin C supplement does not always mean taking more… It means choosing a form that your body can absorb and use.
Natural Factors® Liposomal Vitamin C is a high-quality vitamin C supplement, formulated using genuine liposomal technology. It is a good supplement choice for those seeking superior bioavailability and digestive comfort when taking vitamin C.
