Is iHerb a brand or a marketplace?

Both. iHerb sells third-party brands and stocks its own in-house labels — California Gold Nutrition (CGN) and Sports Research are produced for iHerb. Most listings are well-known third-party wellness brands.

What is California Gold Nutrition?

iHerb's flagship in-house brand. Covers vitamins, fish oil, collagen, protein, and daily wellness staples. In-house brands are typically priced below comparable third-party labels on the same site — actual prices vary.

What is Sports Research?

A wellness brand widely stocked on iHerb. Known for collagen peptides, omega-3, MCT oil, and vitamin D3 K2. Popular among shoppers focused on daily supplements.

What is Now Foods?

A major third-party brand on iHerb. Broad catalogue across vitamins, herbal supplements, sports nutrition, and essential oils. One of the most ordered third-party labels on the site.

Supplements vs Vitamins

Vitamins target specific micronutrients — vitamin C, D3, B-complex, multivitamins. Supplements is the broader category — covers herbal extracts, probiotics, amino acids, collagen, fish oil. Vitamins are a subset of supplements.

Sports Nutrition vs Supplements

Sports Nutrition: protein powder, pre-workout, BCAAs, creatine, recovery aids — tied to training. General supplements: daily wellness staples like omega-3, multivitamin, magnesium. Overlap on items like protein and electrolytes.

Beauty vs Personal Care

Beauty: skincare, masks, serums. Personal Care: shampoo, body wash, oral care, deodorants. iHerb covers both, with selection on clean-ingredient and natural labels.

CGN vs Now Foods

CGN: iHerb's in-house brand — tight focus on core wellness staples, often a value option in a given category on-site. Now Foods: broader catalogue and longer brand history. Both widely reviewed and frequently restocked.

Why Singapore shoppers buy from iHerb

Wider catalogue and competitive per-unit pricing on US-origin wellness brands. Direct access to brands not stocked locally is a frequent driver. Bulk pack sizes and clean-eating pantry items popular for HDB-scale households.

Does iHerb ship to Singapore?

Yes — direct from US warehouses with multiple carrier options at checkout. Delivery typically takes a few business days to about two weeks depending on carrier and order weight; express tiers available at higher cost.

GST and import treatment

Goods imported to Singapore may be subject to GST and import treatment based on prevailing rules and order value. iHerb typically displays applicable taxes and duties at checkout — final figures are subject to current import rules.

HSA-restricted items

Certain supplements, herbal products, and ingredients may be restricted under Singapore Health Sciences Authority rules. iHerb generally blocks restricted SKUs from shipping to SG addresses at checkout.

Free shipping

Free shipping thresholds vary by carrier and order weight — see current minimum at checkout. Heavier consolidated orders often unlock better per-kilo rates.

Authenticity

iHerb sources directly from brand owners or authorised distributors and ships from temperature-controlled US warehouses. Cold-chain items (probiotics, fish oil, certain liquids) use insulated packaging where applicable.

Tropical storage tips

Singapore is hot and humid year-round. Refrigerate probiotics and fridge-marked items on arrival. Keep fish oil, gummies, and softgels in a cool, dry HDB pantry away from kitchen heat and direct sunlight. Use airtight containers for opened powders to prevent humidity clumping. Check expiry on multi-pack or large-size items before stocking up.

Where to buy

iherb.com — direct online ordering. No physical iHerb stores; product is shipped from US warehouses.

iHerb's loyalty mechanic returns a percentage of order value as store credit usable on future orders. Percentage varies — see merchant. May be stackable with on-site promotions, subject to terms.

Trial Prices

Limited-time discounted first-time pricing on selected products, designed to let shoppers try a new brand or SKU at a lower entry price. Availability and pricing vary.

Weekly Specials

Is iHerb worth it for SG shoppers?

For shoppers buying US-origin wellness brands regularly, per-unit pricing is generally competitive. Direct access to brands not stocked locally is the bigger draw for many — eligibility depends on HSA rules at checkout. Rewards Credit, Trial Prices, Weekly Specials, and ShopBack cashback may be stackable subject to current terms — useful for the strongest savings on iherb.com orders shipped to Singapore.
