I did Braggs apple cider vinegar. I also took a magnesium and l-arginine. I am taking a vitamin every 3 days. I also like hemp oil once a week. I figure all this stuff is good while letting the body fast and cleanse during the 23 hour of not eating.
I take flaxseed oil and fish oil for different purposes. If I have to use it externally, I use it as per the need. Hence, I could never differentiate between flaxseed oil and fish oil. Also, there are a variety of fish oils that would be essential for human body.
Both the oils have important nutrients and can be used as a good source of omega 3.
I think that there is a place for both of these foods in a healthy diet. I buy whole flax seeds and grind them in the blender before I use them so that the oil does not go rancid. Flax seeds also have a lot of good fiber, and since they have so much fiber, they can add fullness to foods without adding much of any carbohydrates.
I like to mix flax seeds and chia seeds (which are a good source of proteins as well as fiber), and you can use this as an ingredient when you are making keto bread and crackers, along with almond meal in place of regular white flour.
One of the things that most people miss on the keto diet is something that is similar to bread, which has way too many carbs to be practical on a low carb diet plan.
With the recipes that use ingredients like coconut flour, almond meal, flax and chia seeds, as well as psyllium, you can make good tasting substitutions for regular bread that are low enough in carbs to be used with a keto diet, and the flax and chia seeds also help make them much healthier than regular bread.
They are both healthy and give out body a different nutrients. I am currently taking fish oil and it is good to me. I need flaxseed oil for my chicken skin problem. I have researched that this oil could help to cure the chicken skin. I have this skin condition long time ago and it spreading to many different parts of my body. I have chicken skin in my arms,legs and in my stomach area. It is not itchy but kinda irritating because I could feel the roughness of my damaged area.
