About iHerb
iHerb is an online health and wellness retailer carrying vitamins, supplements, sports nutrition, beauty, and natural grocery products from international brands. For Singapore shoppers, it is one of the more accessible ways to find supplement labels that are not widely stocked locally, often at prices more competitive than pharmacies or health stores here. GST is included in the listed price, so there are no surprise charges at checkout. The range covers everyday vitamins and fish oil through to more specific supplements like magnesium glycinate, collagen peptides, probiotics, and adaptogen herbs. Shop iHerb via ShopBack to earn cashback on your purchases.
Frequently asked questions
iHerb carries international supplement brands that aren't widely stocked in local pharmacies or health stores. Pricing tends to be more competitive, particularly for high-frequency items like magnesium, omega-3, vitamin D3, probiotics, and collagen. Buying a few months' supply at once works out cheaper per unit than buying locally each time. For supplements you take regularly, the difference adds up. Shop iHerb via ShopBack to earn cashback on eligible purchases.
Popular categories include magnesium (glycinate and bisglycinate forms are widely searched), omega-3 fish oil, marine collagen, vitamin D3, probiotics, multivitamins, and vitamin C. Skincare-adjacent supplements like collagen with hyaluronic acid are also frequently purchased. iHerb carries multiple brands per category at different price points, which makes it practical to compare options before committing to a specific product.
iHerb has been shipping to Singapore for years and is widely used here. GST is factored into the listed price at checkout, so there are no surprise fees on delivery. Orders are tracked end-to-end. As with any supplement retailer, it's worth verifying that the specific products you're ordering are not on Singapore's Health Sciences Authority (HSA) restricted import list before placing an order.
iHerb ships directly to Singapore addresses. Delivery typically takes around five to ten business days for standard shipping, with expedited options available for faster turnaround. GST is included in the checkout price, so there are no additional fees on arrival. Ordering above the free shipping threshold reduces the per-unit cost further. For regular supplement shoppers, consolidating into fewer, larger orders tends to be the most cost-effective approach.
iHerb's pricing is generally more competitive than local health stores for international supplement brands, particularly when buying in bulk or stocking up on a few months' supply at once. Ordering above the free shipping threshold reduces costs further. For additional savings on every order, check ShopBack before purchasing. Cashback is tracked automatically on eligible purchases, and for regular supplement shoppers, the cashback on quarterly top-ups adds up meaningfully over time.
