· Do cats and dogs need fish oil?
· What is the use of eating fish oil?
· Why is krill oil better than fish oil?
· Are there any side effects of fish oil/krill oil supplementation in dogs and cats?
· What is the difference between krill oil 40% and 56% concentration?
Former researchers in the field of animal nutrition, combined with XX literature, explained everything about pet fish oil & krill oil in one go.
Let's start with the conclusion:
- Fish oil and krill oil are the few supplements that have been widely proven and have not been overturned;
- Giving fish oil/krill oil to cats, dogs, and even humans is to supplement the Omega-3 deficiency in the regular diet;
- In terms of nutrition and absorption, krill oil is superior;
- The supplement content and process on the market are uneven, and you need to compare them before you can place an order.
1. What is fish oil/krill oil?
Fish oil and krill oil are a class of substances extracted from deep-sea fish and shrimp and are rich in two omega-3 essential fatty acids: DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid).
DHA and EPA are involved in many life activities such as inflammatory response, skin barrier formation, blood lipid regulation, and maintenance of brain function. As "essential fatty acids", animals cannot synthesize them.
2. Is fish oil/krill oil useful?
1. Extensive clinical validation, useful
That is, publishing in high-quality journals.
Associate Professor Xu Jia has summarized the clinical studies on the additional intake of Omega-3 in dogs and cats [1] [2] [3] [4] [5] [6], and believes that its "effects on human and animal health have been widely recognized".
2. What are the manifestations of Omega-3 deficiency in dogs and cats?
According to "Nutritional Needs of Dogs and Cats", the most intuitive manifestations of dogs and cats lacking in Omega-3 are dry hair, dull coat color, increased non-seasonal hair loss, and increased skin itching.
Looking at it at a deeper level, it is more worthy of our attention.
When Grey Boy was first adopted, his nutritional status was not very good, and he suffered from feline ringworm, so I ensured that he took additional Omega-3 supplements while actively taking medication, and successfully evolved from a poor child with dry hair to a healthy boy who did not go to the hospital except for physical examinations:
Fur close state:
I've been researching small animal nutrition for many years, and the only thing I recommend for all daily supplements for dogs and cats is omega-3 supplements, including fish oil and krill oil.
3. What is the difference between fish oil and krill oil?
1. The absorption efficiency is different
The lipids of fish oil are triglycerides, which cannot be broken down in the stomach and need to be absorbed into the lymphatic system after emulsification of bile salts in the small intestine, and at the same time, the fat needs to be dissolved in the absorption process.
Most of the lipids in krill oil are phospholipid type, which can be broken down in the stomach and absorbed directly in the small intestine.
The difference in structure can reach 95-98%. [7] [8] [9]
As a result, in a 4-week randomized, double-blind placebo control in which different groups were given krill oil and fish oil with similar levels of Omega-3 content, krill oil increased the level of Omega-3 in the blood of animals significantly higher than that of fish oil. [10]
In short, krill oil is easier to absorb and more effective than fish oil.
2. Different heavy metal content
In 2015, LabDoor, a supplement quality inspection agency, tested 30 of the best-selling fish oils in the U.S. and was shocked.
The reason for this is that in recent years, marine pollution has caused heavy metals to be passed through the marine food chain, and the higher the predator, the higher the content of heavy metals in the body.
And krill, because of its weakness, has become a clean food.
For supplements, if it is risky to eat, it is better not to eat them altogether. Although the process of fish oil has been optimized, the best and most expensive process is still less reassuring than the inherently safe raw material.
3. The nutrients are different
Krill oil not only contains highly absorbable phospholipid Omega-3 fatty acids, but also high content of choline and astaxanthin.
Krill oil contains more proven beneficial ingredients than fish oil, mainly astaxanthin, choline and phospholipids.
Astaxanthin is a natural antioxidant, which also makes krill oil do not need additional preservatives to preserve, choline participates in liver metabolism, muscle contraction, brain signaling and other physiological activities, phospholipids care for blood vessels, these three types of substances are sold separately on the market, and krill oil can be supplemented in one stop, more cost-effective.
Fourth, the comparison of hot fish oil and krill oil
As a former industry insider, I firmly believe that good products are always comparative.
I have bought the best-selling Omega-3 supplements on the market in order to compare the quality and actual feeding experience.
Combined with multiple dimensions such as ingredients, content, and process, the horizontal comparison data are as follows:
1. Omega-3 content and absorption
On paper, MAG Super Concentrated Fish Oil has the highest Omega-3 content (95%) and also uses the best and most expensive rTG fish oil refining process on the market (rTG>TG>EE).
However, experiments have proven that Dolex is superior in terms of health effects.
As mentioned earlier, fish oil is lost in structure.
2. Ingredients and additives
Although safflower seed oil, oilseeds and their products are rich in Omega-3, ALA (α-linolenic acid), which is of little use to dogs and cats, has no meaning in the ingredients except to increase the book data.
Then again, due to the natural and easily absorbed structure of krill oil, dole's krill oil does not require any additives, and krill oil does not have the risk of heavy metal enrichment, so it is better than fish oil in general.
I've been supplying raw materials for a while, so I'll just say a few more words. Due to the large number of krill oil ingredients, the refining process is much more complex than fish oil, and there are only a handful of manufacturers in the world that can stably supply raw grade krill oil.
3. International certification
The most foolish way to buy an Omega-3 supplement is to look at the certification.
Internationally recognized as the highest gold content certification, fish oil is IFOS (International Fish Oil Standard), krill oil is IKOS (International Krill Oil Standards), can get these two representatives of the certification of the product is not many, the horizontal test products only Doleshi and MAG.
In addition, Dole also has the ORIVO Pure Oil certification, which is the representative of the company, which further ensures food safety.
4. Capsule shape
When supplementing cats and dogs with Omega-3, the capsule should be broken and poured into dry food or canned food, so the shape of the capsule is very important.
Many bloggers will recommend everyone to buy products for human use, saying that human grade products are safer. But in fact, high-quality pet supplements are also human-grade ingredients.
But professional pet omega-3 supplements have an advantage, they are very convenient to feed, and you don't need to use scissors to cut them to make your own hands smelly.
brief summary
Due to the natural influence of structure, food safety, and nutrients, even MAG super-concentrated fish oil, which is the ceiling of fish oil quality, cannot compete with krill oil.
The industry can also find the experimental report of Dole krill oil, after 30 days of experiments, the cat hair gloss and skin elasticity in the Dole krill oil group have been significantly improved.
Based on product performance, experimental verification and actual feeding experience, Dolex High Energy Krill Oil (56% phospholipid concentration) is undoubtedly the most worthwhile product to buy.
If you must mention the disadvantages, the feeding cost of this krill oil is about 3.3 yuan/day, which is a little higher than that of fish oil products (about 2.5 yuan/day).
However, you can't just look at the price, krill oil is 6 times more efficient than fish oil, and it can be quickly effective in the short term, so you don't have to eat it all the time like fish oil.
The feeding strategy I chose was to feed the gray boy a slightly more expensive and high-content 56% krill oil during the moulting season (spring and autumn), which could be eaten for 2 months for 199 yuan, which was just enough to cover the year's supply.
In the non-moulting season, choose another krill oil (40% concentration) of his family totaling 2.3 yuan / day, and feed one capsule every two days is safe and cost-effective.
One final thing to emphasize
Cats and dogs have brightened and supple their coats to become more supple and supple, but they are just the most likely changes we observe with Omega-3 supplementation.
Compared with this, visceral health, blood health, and nerve health deserve more attention.
As a practical supplement with a long research history + clinical verification + many safety reports, Omega-3 supplement is the only product I dare to recommend to shovelers and their pets.
For friends who have cats and dogs, enough high-quality dry food + occasional canned staple food + supplementing Omega-3 according to their ability is the "public pet ceiling". If you want to give your pet the best in terms of animal nutrition, it's actually as simple as that.
