A high-potency liposomal vitamin C enhanced with biotin and potassium in a liquid sachet - delivering dramatically superior absorption over standard tablets and capsules to support immune function, collagen production, energy metabolism, and cellular protection in a single daily dose.
Vitamin C is the most widely supplemented nutrient in the world, yet most people taking it are absorbing a fraction of what they think. Your body cannot produce or store vitamin C - every milligram must come from diet or supplementation, and any excess is rapidly excreted. This makes consistent, well-absorbed daily intake essential rather than optional.
Vitamin C is a cofactor in collagen synthesis, which means your skin, bones, cartilage, gums, teeth, and blood vessels depend on it structurally. It is required for immune cell production and function, for the regeneration of other antioxidants including vitamin E, and for the absorption of non-haem iron from plant-based foods. It contributes to normal energy metabolism and protects cells from oxidative stress. When intake is inadequate, the consequences compound quietly: slower wound healing, duller skin, weakened immunity, increased bruising, fatigue, and accelerated visible ageing.
The problem is not that people fail to supplement - it is that the supplements they take fail to deliver. Standard ascorbic acid tablets and effervescent vitamin C dissolve in the stomach, where a significant portion is degraded by gastric acid before absorption can occur. The intestinal transport system for vitamin C is saturable, meaning that beyond approximately 200 mg in a single oral dose, absorption efficiency drops sharply - at 1,000 mg, you may absorb less than half, with the remainder passing through the gut and often causing bloating, cramping, and digestive discomfort. You pay for a gram on the label and your bloodstream receives a fraction, while your stomach absorbs the consequences of the unabsorbed remainder.
Cymbiotika's Liposomal Vitamin C bypasses this limitation entirely. Each sachet encapsulates vitamin C within phospholipid spheres derived from sunflower lecithin - microscopic lipid vesicles that protect the molecule through the stomach and deliver it intact to the bloodstream via direct cellular uptake, not the saturated intestinal transport pathway. This is the same phospholipid technology used in pharmaceutical drug delivery where bioavailability is non-negotiable. The result is dramatically higher blood plasma levels of vitamin C compared to equivalent doses in tablet or capsule form, with none of the gastric side effects. The formula is enhanced with biotin, which contributes to the maintenance of normal skin, hair, and mucous membranes, and potassium, which contributes to normal muscle function and the maintenance of normal blood pressure. 30 liquid sachets per box - a full month's supply.
Vitamin C contributes to the normal function of the immune system, normal collagen formation for the normal function of skin, bones, cartilage, gums, teeth, and blood vessels, the protection of cells from oxidative stress, normal energy-yielding metabolism, and the reduction of tiredness and fatigue. Vegan, non-GMO, gluten-free, soy-free, no artificial colours or preservatives.

People who understand that the amount of vitamin C on the label is irrelevant if it never reaches the bloodstream choose liposomal delivery over conventional tablets. It reflects a precision approach to supplementation - optimising what your cells actually receive rather than what the packet claims. You gain immune resilience, which removes the vulnerability created by poorly absorbed vitamin C and enables your immune cells to function at capacity with a consistent, bioavailable daily supply You gain collagen integrity, which removes the structural decline that manifests as ageing skin, weakened gums, and slower healing and enables ongoing synthesis of the protein that holds your body together You gain cellular protection, which removes the accumulating oxidative damage from stress, pollution, and metabolic activity and enables your cells to neutralise free radicals before they cause lasting harm.
You gain sustained energy, which removes the fatigue and afternoon crashes associated with suboptimal vitamin C status and enables normal energy-yielding metabolism throughout the day.
You gain iron absorption support, which removes the barrier to non-haem iron uptake that affects plant-based and vegetarian diets and enables your body to access more iron from every meal

Sign inStandard ascorbic acid is absorbed via a saturable intestinal transporter, meaning large doses are largely excreted rather than absorbed. Liposomal vitamin C encases the ascorbate in phospholipid vesicles that may bypass this pathway, potentially delivering more to the bloodstream. The evidence for liposomal superiority is promising, though research is still developing.
Vitamin C is well known to enhance the absorption of non-haem (plant-based) iron, so taking it alongside an iron supplement or an iron-rich meal is a common and evidence-supported practice. Check with your GP or pharmacist if you are on prescribed iron therapy.
People with higher vitamin C requirements — those under frequent physical stress, recovering from illness, eating few fresh fruits and vegetables, or who smoke — are most likely to notice a benefit. It is also worth considering if standard vitamin C tablets have caused you digestive discomfort at effective doses.
Vitamin C is water-soluble and excess is generally excreted, making toxicity at typical supplemental doses uncommon. However, very high long-term intake may increase the risk of kidney stones in susceptible individuals. Check the packaging for the serving size and stay within it unless advised otherwise by a clinician.
Vitamin C works continuously as an antioxidant and immune co-factor rather than producing a noticeable acute effect in most people. Supporting adequate status over weeks is the goal. If you are taking it to support recovery from a specific deficiency or illness, a blood test before and after is the most reliable way to assess impact.
Overall

I've had issues with standard vitamin C tablets causing bloating for years, so switched to this after reading about liposomal delivery. Three weeks in and no digestive issues at all. Hard to say whether the absorption difference is measurable but I feel like it's doing its job. Taking it each morning alongside my iron supplement. Will re-order.

Does what it says. Noticeably less run-down this winter than last year — whether that's this or just luck I can't say, but I'll keep taking it.

Really rate the quality and I do think the liposomal format makes a difference compared to the cheap tablets I was using before. That said, £56.95 is a lot to maintain monthly. I'll keep buying it but would love a smaller starter size at a lower price point to make it more accessible. Minor gripe in the grand scheme of things.

Stacks well with my multivitamin — no issues mixing it into my morning routine. Texture is smooth and it doesn't have that sharp acidic hit you get from powder forms.

Was taking a standard ascorbic acid tablet for ages and kept reading that a lot of it just gets excreted. Gave this a go and genuinely think my energy and skin look better after about six weeks. I take it before bed. Not cheap but feels worth it.

Bought this on the back of a friend's recommendation after she swore by it during marathon training. I'm doing a half in spring and wanted something to support recovery. Easy to take, no aftertaste issues, and I feel like my immune system has held up well through a heavy training block.
