Products with fake reviews

Omega−3 fatty acids also called ω−3 fatty acids or n−3 fatty acids.

Omega-3 fatty acids are some of the most essential and used nutrients you can put in your body.

They help to combat inflammation and joint problems, as well as provide an important structure to our brains and nervous system.

There are 3 Main Types 

Your body’s cells need Omega-3’s to function properly. All cells are made up of cholesterol, saturated fats, and polyunsaturated fats.

The saturated fats and cholesterol help to maintain the structural integrity of the cell membrane while polyunsaturated fats allow for fluid motion.

The fluid in your body transports cell communication and other processes across cell membranes.

Nutrigenomics has shown studies that a diet rich in Omega-3’s can positively affect gene expression.

The truth about the fish oil category is that 90% of the top product listings on the major websites above are misleading, overpriced, and have not met quality standards.

1. Front-label claims 

 Many companies will write claims of 1,000 mg, 1,400 mg, 50,000 mg fish oil on the front of the bottles. The reality is most of the time these claims will not be true. It is very important for you to read the entire bottle including the back to calculate for yourself the actual true oil content in each bottle and serving.

2. Choosing brands where EPA (eicosapentaenoic acid) & DHA (docosahexaenoic acid) Content make up only 30% total EPA/DHA per serving, the rest is useless filler oil. 

If you like brands only because of popularity, and reading on the superficial advertising, it’s likely you could get stuck with very low-quality fish oil. Many popular brands do not have the adequate % EPA/DHA ratio to really ensure that you get the most amount of oil per serving.

3. Product Quality (IFOS Rated) - International Fish Oil Standards is an independent 3rd Party certification and rating agency that tests fish oil products against 5 markers of quality:

A. Purity, safety, and cleanliness (PCBs and highly toxic chemicals like dioxins and furans)

B. Heavy metal content (mercury, cadmium, lead, arsenic)

C. Accurate labeling (actual DHA & EPA levels vs. labeled claims)

D. Oxidation and stability (peroxide, anisidine levels)

E. Omega-3 concentration (>60% omega-3-to-total oil)

4. Basing Decision on big name brand recognition

Most big brands have their resources divested in a wide variety of products. Fish oil is a very specific type of Omega-3 fatty acid that requires precise attention and care to serve customers. Unfortunately, many big-name brands have profited from other sectors and do not require this attention and care to earn your trust. 

In turn, the have:

  • Instant brand name recognition & credibility (e.g. Optimum Nutrition, GNC)
  • Intentionally deceptive marketing & labeling & add on sales
  • Easily convince you through customer naivete and impulse buying

5. Confused about the cost per gram vs. cost per serving 

If you try to select the cheapest rather than the most quality based on a rating system, it’s likely you could end up with toxin-laced, farmed fish that can actually do more harm than good. Your goal for taking Omega-3 fatty acids via fish oil is to improve your health, not only generate profits for a large conglomerate company.

Take the time and care to review these ratings so you can make the best choices for you and your family.
