We've put together a real ranking based on data about what our service's users buy on iHerb. These are the vitamins and supplements that customers add to their cart again and again and ship home — to Russia, Belarus, Kazakhstan — at special low shipping rates from iHerb.
Liposomal inositol powder with berry flavor — a product for women's reproductive health. Inositol is used for polycystic ovary syndrome and pregnancy preparation. The liposomal form — a technology in which the active substance is packaged in phospholipid vesicles and absorbed better than regular powder. Among women with PCOS and those preparing for IVF, the product is in steady demand — combined formulas of this level are practically unavailable in Russian pharmacies.
Zinc in picolinate form — one of the best forms in terms of absorption. Picolinate binds zinc to picolinic acid, providing better absorption than oxide or sulfate. Zinc is important for the immune system, wound healing, skin condition, and reproductive function in men. Thorne is an American brand with strict production standards and formula purity; its products are used by professional sports teams and integrative medicine physicians.
NAC, or N-acetylcysteine — a precursor of glutathione, the body's main antioxidant. Glutathione neutralizes toxins in the liver, protects cells from oxidative stress, and participates in the immune system. With age and under the influence of alcohol, medications, and pollution, glutathione levels decrease, and acetylcysteine helps restore it. In this formula, Doctor's Best combines NAC with other nutrients to enhance the antioxidant effect. NAC is used for liver detoxification, bronchopulmonary problems, and general antioxidant support. It is difficult to buy pure NAC without additives and fillers in Russian pharmacies, so the supplement is ordered on iHerb.
L-methylfolate — the biologically active form of folic acid. In a significant portion of the population, regular folic acid is poorly converted into active methylfolate, and standard vitamins with folic acid work poorly. Jarrow Formulas methylfolate is absorbed directly; it is especially important when planning pregnancy and in the first trimester, for cardiovascular diseases, depression, and anxiety. Vegan formula without dairy components and gluten.
Liquid liposomal vitamin C — a formula in which the vitamin is packaged in phospholipid vesicles and absorbed better than regular tablets. Citrus-vanilla flavor, sugar-free. It is practically impossible to buy liposomal vitamin C in Russian retail, so the category of liposomal supplements from iHerb is consistently in demand. Premium segment for those who need maximum bioavailability.
Large pack of magnesium from Doctor's Best — a backup format for those who take magnesium on a regular basis. Chelated form (glycinate-lysinate from Albion Minerals) — a patented combination with confirmed high bioavailability, does not cause a laxative effect, does not irritate the stomach. Magnesium in this form is suitable for cramps, sleep disorders, muscle tension, helps cope with stress, and supports the nervous system.
Liquid D3 for infants and young children based on medium-chain triglyceride (MCT) oil. Pediatricians almost universally recommend vitamin D3 for children in the first year of life: breast milk contains insufficient D3, and synthesis in the skin of infants is low. The composition is clean — without preservatives, artificial colors, flavorings, or allergens. One of the most frequent orders in the children's category through iHerb.
Concentrated omega-3 in Triple Strength format. Raw material — wild Alaskan pollock with MSC sustainable catch certificate. Molecular distillation removes mercury and heavy metals. Sports Research is an American brand from Los Angeles focused on sports nutraceuticals and a quality raw material base. Omega-3 is used to support the cardiovascular system, joints, dry eyes, and to reduce systemic inflammation.
Magnesium taurate — a combination of the mineral with the amino acid taurine. Magnesium taurate supports heart and blood vessel function and helps with anxiety and sleep disorders. The formula also includes vitamin B6, and the entire combination is packaged in liposomes for increased bioavailability. A premium product for people with hypertension, arrhythmia, anxiety, and insomnia. Magnesium taurate is difficult to find in regular retail; ordering from iHerb becomes the only reasonable option.
One of the best multivitamin complexes on iHerb in terms of quality-to-price ratio. The formula contains active forms of vitamins and minerals: methylfolate instead of regular folic acid, methylcobalamin instead of B12, P-5-P instead of B6, zinc, selenium, and chromium in chelated forms. Suitable as a basic complex for active adults, under increased loads, and on vegan and vegetarian diets.
Concentrated omega-3 from NOW Foods — one of the most in-demand products in the NOW vitamin line on iHerb. Raw material from deep-sea fish, molecular distillation from mercury and heavy metals. NOW Foods omega-3 — the optimal balance between concentration and price. It is difficult to buy NOW vitamins with such concentration in Russian retail — pharmacies usually have basic fish oils with EPA and DHA 2-3 times lower, so those who care about high quality prefer to order from iHerb.
Slow-release iron format — a technology in which iron is released gradually over several hours. This allows taking a high dose without the side effects typical of regular iron sulfate: nausea, stomach heaviness, constipation. The formula also includes B vitamins, folic acid, and vitamin C for iron absorption. Suitable for iron deficiency anemia, pronounced ferritin deficiency, heavy menstruation, and postpartum recovery.
Basic magnesium from Doctor's Best in chelated form — a patented glycinate-lysinate combination from Albion Minerals with confirmed high bioavailability. Absorbed better than oxide and carbonate, does not cause a laxative effect, does not irritate the stomach. The most budget-friendly working magnesium supplement on iHerb — an option for those who just need to cover the basic magnesium requirement without overpaying for premium formulas. Suitable for cramps, sleep disorders, and muscle tension.
Vitamin D3 in a dosage of 2000 IU — the optimal option for daily intake. D3 is needed for the immune system, bone density, muscle strength, testosterone synthesis, and affects mood and sleep quality. NOW Foods produces D3 in the form of cholecalciferol in olive oil — this form is absorbed better than D3 in tablets or powder. NOW vitamins have led this category on iHerb for many years, partly due to price — one capsule costs 3-4 times less than Russian pharmacy analogs with the same dosage.
High dosage of NOW vitamin D 5000 in a compact pack — one of the most popular formats in the category. The price on iHerb is excellent: $4.71 per pack, which translates to less than 4 rubles per capsule. The 5000 IU dosage — working for correcting pronounced vitamin D deficiency. It is convenient to buy NOW vitamins in this dosage for the whole family. The capsules are small, easy to swallow, with no taste or smell.
The same item as in 6th place, but in a large pack — 240 capsules instead of 120. At a price of $8.91, the per-capsule cost is even lower. One of the most cost-effective ways to cover the annual vitamin D3 requirement for the whole family. Vitamin D3 from NOW Foods is chosen precisely because of the honest formula at an honest price — cholecalciferol in oil capsules, without anything extra, in a dosage that works.
One of the most popular collagen powders on iHerb — and California Gold Nutrition itself consistently ranks among the site's top-selling brands. Hydrolyzed marine collagen types I and III. The formula includes hyaluronic acid and vitamin C, without which the synthesis of one's own collagen is impossible. Tasteless and odorless, dissolves in any liquid. A 2-3 month course gives a visible effect on skin, hair, and nails.
Doctor's Best patented zinc and L-carnosine complex (PepZin GI), developed in Japan to protect the stomach lining. In this combination, zinc L-carnosine works not as a regular mineral but as a local protective agent: it stays in the stomach longer, adheres to the walls, and supports mucosal integrity. According to clinical studies, zinc carnosine is used for gastritis, reflux, peptic ulcers, and recovery after prolonged NSAID use (ibuprofen, aspirin). In Russia, this item is consistently in demand — there are practically no analogs with PepZin GI in pharmacies; gastroenterologists specifically recommend this drug to those who want to add mucosal protection to their main therapy. L-carnosine gastro shows noticeable improvements after a 4-6 week course.
One of the best B-complexes on iHerb in terms of quality-to-price ratio. All B vitamins are presented in active methylated forms: folic acid as L-methylfolate, B12 as methylcobalamin. This is especially important for those whose metabolism makes it difficult to convert regular inactive forms of B vitamins into working ones. Supports energy metabolism, the nervous system, brain function, and skin condition. Suitable for chronic fatigue, anxiety, postpartum recovery, and vegan diets during periods of increased load.
The undisputed leader of the list — a complex of six forms of magnesium in one tablet (malate, succinate, citrate, fumarate, taurate, aspartate). Each form has its own action: malate increases energy levels and helps with chronic fatigue, citrate relieves muscle spasms and cramps, taurate supports heart and blood vessel function, fumarate and succinate participate in cellular energy production, aspartate affects the nervous system. The formula includes vitamin B6 for better magnesium absorption. Source Naturals is one of the oldest American manufacturers of premium supplements. On iHerb, this item has been among the sales leaders among magnesium supplements for years.
