Haroutine

It is safe but more than most people need. The adult RDA is 75–90 mg and the tolerable upper limit is 2,000 mg, so 500 mg sits comfortably in between. The catch is that the body's fractional absorption of vitamin C drops sharply above roughly 200 mg in a single dose, with the excess excreted in urine. That means the practical difference between this and a 200–250 mg product is smaller than the price gap suggests, liposomal delivery or not.

Check with your doctor first. Vitamin C is metabolised to oxalate, and intakes of 1,000 mg or more daily have been associated with an increased risk of calcium oxalate kidney stones, particularly in men. At 500 mg the risk is lower, but if you have a personal history of oxalate stones this is worth raising with your GP or urologist before taking it daily. The page carries no warning on this.

No — speak to your doctor. Vitamin C substantially increases the absorption of non-haem iron from food, which is useful for most people but is exactly the wrong effect if you have haemochromatosis, thalassaemia or any iron-loading condition. High-dose vitamin C is generally avoided in those circumstances, and the page does not mention it.

Not quite. It is genuinely sugar-free — stevia-sweetened, zero sugars, 5 g carbohydrate of which 4 g is fibre, so the blood-glucose impact is minimal. But the page omits something directly relevant: high-dose vitamin C can interfere with readings on some blood glucose meters and continuous monitors, producing falsely high or low results depending on the system. Mention it to your diabetes nurse or team, and check your meter manufacturer's guidance before taking 500 mg daily.

It might. Each serving contains 4 g of fibre from organic agave inulin and chicory root fibre. Both are prebiotic fructans and both are FODMAPs, which commonly cause bloating, wind and abdominal discomfort — and are a frequent trigger in IBS. If you are sensitive, start with one gummy rather than two, or choose a format without an inulin base.

The ascorbic acid is encapsulated in a lipid structure built from sunflower lecithin and rice bran wax, intended to protect it through digestion and improve uptake. Cryo-TEM verification, which the page cites, is a legitimate way to confirm the liposomes have genuinely formed. The absorption evidence, however, is limited: a randomised but open-label single-dose study in 20 healthy fasting men, sampled over 24 hours, run by BioRadius Therapeutic Research and Wooree Green Science in 2024 — and, as Haroutine states itself, conducted on 704.2 mg delivered as two capsules rather than on these gummies. The 3x, 1.7x and 1.9x figures appear in a comparison table with no underlying data shown.

Rather a lot. Disclosing that the study used a different dosage form, that it was open-label, that the participants were 20 healthy males, and that dosing was single and fasted gives a reader everything needed to judge the claim's limits. Most supplement pages would simply print "3x absorption" and stop. The research sponsors and year are also named, which allows the study to be looked up.

Third-party testing and Cryo-TEM verification are claimed and a certificate of analysis is shown as an image, but no laboratory is named and no results appear in text. Ask for the readable COA for the batch you receive, confirming the 500 mg vitamin C content per serving. The Cryo-TEM images would also be worth requesting, since they are the evidence that the liposomes exist.

The page contradicts itself: the product states "Made in USA" while the site tagline says "Made in South Korea". One of those is wrong, or they refer to different stages (formulation versus manufacture). Ask the company to clarify before ordering if origin matters to you.

Reviewers consistently describe the strawberry guava flavour as good but quite sour, which is what you would expect from 500 mg of ascorbic acid with no sugar to mask it. Several also report the gummies sticking together — a common issue with pectin gummies in warm conditions. The single-serving packets help, but store them somewhere cool.

A "30-day Guarantee" is stated without terms, so check the linked refund policy for whether opened packets qualify and who pays return postage. Free shipping applies over $40, which a single $28.98 bottle does not reach. Subscription pricing, frequency and the contents of the first-shipment welcome kit are all unstated — clarify before signing up to a recurring order.

At the time of review this product was shown as sold out, as were the Liposomal Vitamin D3 + K2 gummies and the Liposomal Vitamin C powder packets. If you want the same dose in a different format, the powder packets are the alternative — check availability before planning around either.

Yes. Every Haroutine code listed on smartstorereview is tested before publication and rechecked regularly. Since a single bottle at $28.98 falls below the $40 free-shipping threshold, check whether a code plus a second item works out better than a code alone — and confirm whether codes apply to subscription orders.
