"The flavor is definitely strong—I usually add flaxseed oil to my coffee, but with this one, the taste completely overpowered my drink, so it wasn't a good fit for that method."

"I've ordered this product more than once and unfortunately, both times the oil arrived rancid. The bottle was dark and had a thick, unpleasant sediment at the bottom. It's disappointing considering how expensive it is, and I haven't received any helpful response from the seller."

FTB Score

What We Like

  • High product quality
  • Affordable price
  • Good flaxseed taste
  • Contains healthful lignans
  • Supports overall health

What We Don't Like

  • Includes sunflower oil
  • Some sediment in bottle

What Customers Say

"I've purchased this flaxseed oil several times and find the quality consistently high. The taste is pleasing, especially compared to other brands I've tried, and the price point is excellent—much more affordable than pricier options. The label notes a small amount of sunflower oil, which I learned is just used as an excipient. There's some sediment at the bottom from the flax seeds, but a good shake mixes it back in, and it actually contains beneficial lignans."

"After many years of using flaxseed oil from various sources, I was surprised by this bottle, and not in a good way. The inclusion of sunflower oil wasn't disclosed on the front label, which felt misleading. When I opened it, I found dark sediment and the oil was much darker and more bitter than expected. I was concerned by the amount of residue inside and ultimately, I wouldn't recommend this product to others."

"I've used six bottles over the past year and genuinely enjoy the flavor of this flaxseed oil—it reminds me of fresh flax seeds. While there is some sediment at the bottom, the oil itself is a beautiful light yellow and clear when poured. My only minor concern is the addition of sunflower oil, since I prefer to avoid it due to its omega ratio."

"I tried this flaxseed oil for the first time to season my Blackstone griddle after noticing some rust spots in our humid climate. While the oil tasted a bit bitter straight out of the bottle, it worked really well for seasoning. No bitter flavor carried over to the food and the griddle has stayed rust-free for months.

Frequently Asked Questions (FAQs)

1. What are the benefits of flaxseed oil capsules?

Flaxseed oil capsules offer several benefits. They can help reduce cholesterol and blood sugar levels, treat digestive conditions, and even have potential anti-inflammatory properties. Additionally, flaxseed oil is rich in phenolic compounds, which may offer protection against certain cancers. It also contains minerals and fiber that can improve gastrointestinal health and prevent constipation.

2. Is it OK to take flaxseed oil everyday?

Taking flaxseed oil capsules daily is generally considered safe for most adults. A typical dosage of 2 grams per day has been used safely for up to 6 months. However, higher doses of up to 24 grams per day may cause side effects like loose stools and diarrhea. It's important to start with a small amount and gradually increase it to allow your body to adjust to the supplement.

3. What does flaxseed oil supplements do for females?

Flaxseed oil supplements offer several benefits for females. The phenolic compounds in flaxseed oil can help protect against various cancers, while proteins can reduce the risk of heart disease. The presence of minerals like calcium, magnesium, and phosphorus, as well as fiber, can improve gastrointestinal health and prevent constipation.

4. When should I take flaxseed oil pills?

To get the most out of flaxseed oil capsules, it is recommended to take them in the morning, before breakfast. If you are new to taking flaxseed oil, start with a small amount and gradually increase it as your body gets used to the supplement.

5. Who should not take flaxseed oil capsules?

Flaxseed oil capsules may not be suitable for individuals with certain conditions, including bleeding disorders, bowel obstruction, diabetes, diverticulitis, inflammatory bowel disease, low blood pressure, and hypoglycemia. If you have any of these conditions, it's best to consult with your healthcare provider before taking flaxseed oil capsules.

6. Does flaxseed oil increase estrogen?

Contrary to popular belief, flaxseed oil does not significantly increase estrogen levels. In fact, it may slightly decrease estrogen levels. Flaxseed oil contains phytoestrogens, such as lignans, which can bind to estrogen receptors and potentially have a mild estrogen-lowering effect.

7. What are the side effects of flaxseed in females?

While flaxseed offers many health benefits, it can also have side effects in some individuals. These may include bloating, gas, constipation, stomach aches, diarrhea, intestinal obstruction, or allergies. Pregnant women should avoid flaxseed during pregnancy or breastfeeding because it can mimic the effects of estrogen on the body.

8. What are the side effects of flaxseed oil capsules?

While flaxseed oil capsules are generally safe, some individuals may experience allergic reactions, such as itching, swelling, redness, or hives. Vomiting and nausea can also be signs of an allergy. If you have a severe allergic reaction that causes your throat to tighten or difficulty breathing, seek immediate medical attention.
