What can you buy on iHerb Singapore?

iHerb is probably best known for vitamins and supplements, but there’s much more available online. You can add skincare and beauty products to the same basket as protein powders, pantry staples and snacks.

Parents can stock up on baby puffs, fruit and veggie pouches and toddler snacks; gym-goers can browse protein bars, electrolytes, creatine and pre-workout products; and the beauty section covers everything from Korean skincare to haircare.

There are plenty of familiar international names on iHerb Singapore too, such as NOW Foods and Nordic Naturals for supplements, Vital Proteins for collagen, Mielle for haircare and Bob’s Red Mill for pantry staples.

So, what’s making its way into Singapore carts?

Magnesium, probiotics, omega-3s and B vitamins are all popular additions to the supplement cupboard, covering everything from everyday nutrition to gut health. Here are six options you’ll find on iHerb Singapore.

#1 Doctor’s Best High Absorption Magnesium

Sleep, mood, muscles and nerves – magnesium has quite a few jobs to do. In fact, it’s essential to 600 enzyme systems that support biochemical functions in the body. Available on iHerb Singapore, Doctor’s Best uses 100% chelated magnesium lysinate glycinate for high absorption, with each tablet providing 100mg of magnesium. The formula is also non-GMO, vegan and free from gluten and soy.

#2 California Gold Nutrition LactoBif Probiotics

These probiotics from iHerb Singapore combine eight active strains – five Lactobacilli and three Bifidobacteria – with 30 billion CFU in each capsule. Aimed at supporting digestive and gut health, the capsules are individually double-foil blister sealed to help keep the probiotics protected.

#3 California Gold Nutrition Omega-3 Premium Fish Oil

Not getting enough omega-3s through your diet? This fish oil adds EPA and DHA to your daily routine, with 180mg of EPA and 120mg of DHA in each softgel. These omega-3 fatty acids support normal heart function, while DHA also supports normal brain function and vision.

#4 Life Extension BioActive Complete B-Complex

For days when there never seem to be enough hours, this formula brings together the B-vitamin family, including B1, B2, B6 and B12. The vitamins come in biologically active forms that are easier for the body to use, helping to support energy production and a healthy metabolism.

#5 California Gold Nutrition Kids Liquid Calcium

There are options for younger members of the family on iHerb Singapore too. For kids who want to be as strong as their favourite superhero, this liquid supplement combines calcium with magnesium, vitamin D and zinc to support bone health. Suitable from age four, it has a natural orange flavour and can be taken directly or mixed into a drink. 

#6 k2o by Kylie Jenner

Got Kylie Jenner’s k2o on your wish list? The Advanced Skin Hydration Mix comes in individual drink-mix sticks in flavours like Watermelon Lime and Strawberry Lychee. Each combines electrolytes with hyaluronic acid and collagen peptides to support skin hydration and elasticity. iHerb is the exclusive international retailer, so it’s the only place to buy the brand outside the US.

How does iHerb check product quality?

Buying vitamins and supplements online can involve a fair bit of label-reading and research. iHerb does some of that legwork for you, with a three-stage quality process that checks the raw ingredients, manufacturers and, finally, the finished products. These are independently tested in the US, giving you a little more reassurance about what you’re buying.

So, how long will your order take and will you get hit with extra charges?

Orders are shipped directly from iHerb warehouses, helping the company manage freshness and quality from storage through to delivery. You’ll see an estimated delivery date at checkout, and iHerb offers free shipping on Singapore orders over $30.

As for extra charges, Singapore’s 9% GST is already included in iHerb’s prices for orders of $400 or less, so there’s no extra GST added at checkout. Customs duties may still apply depending on what you order.

How much can you save on iHerb Singapore during Golden Week?
