First, the herb is called turmeric. Circumin is what they've named one active compound in the plant that they think is responsible for some of what people take it for. How much you take and when depends on why you're taking it. As a spice, it's used for flavor, especially in Indian food, so for that you'd use it as you'd use any spice. I don't recommend using the powder for anything else, however. For one thing, it's a hot spice, so it burns if you use too much powder. For another, the powders used for spices are not necessarily tested for circumin concentration and probably isn't. For a third, unless you're buying organically grown spices, most commercial spices are irradiated, which can destroy beneficial properties when used for health. So to get enough of it, you want to use a supplement. Now, next, supplements vary a lot in quality and in type. The least potent is taking a capsule that just contains some powder. Next is a capsule that contains a standardized amount of circumin, which is usually recommended for health purposes. However, do know that any standardized supplement alters the natural status of it because in nature, amounts vary and the plant contains a lot of active ingredients many of which have unknown effects because they haven't been studied. In order to standardize a supplement, one marker chemical is chosen that is believed to be the reason the supplement works, but this hasn't always turned out to be the right substance. But it does seem to have held up with turmeric. Next are tablets, which are harder than capsules to absorb. Next are extracts or tinctures, which is the herb's components extracted usually with alcohol and sometimes nowadays with more expensive and better quality supplements by a combination of alcohol and what is called super critical extraction, which is better than alcohol in extracting fat soluble components. A combination of the two methods is best. An extract can be standardized or not. Historically, extracts were preferred by herbalists if they wanted a strong herb and a tea for a weaker water extraction, which is, next, using the powder to make a tea. I wouldn't recommend that with turmeric, though, nor would I recommend it taken as an extract, because again, it's a hot tasting herb that burns going down. Confused? You should be, because nobody can tell you exactly how much to take nor what form is the best. Again, it depends on the purpose you're using it for. Turmeric is used for the following purposes: as an anti-inflammatory; as a powerful antioxidant for liver protection; as a digestive bitter; as a blood thinner; as a fat burner because hot herbs heat up the body and supposedly that helps the body to burn fat -- probably doesn't. That's just five off the top of my head. You haven't said why you want to use it, but I would say it's a good herb to use for someone missing a gall bladder because that puts more stress on the liver to do its job -- the gallbladder is a storage place for liver bile so you can digest fat and without it your body has no reserve to draw on and has to rely completely on the liver. Which purpose you're using it for determines the best form and how much to take. Often with herbs, it's more important to take it several times a day, or a least twice with a hot herb like turmeric, than how much you take, but for how much you need to consult a few good herbals and see which one you like. As for when, again, it's a hot herb, so take it with a meal. That will buffer it so you don't get heartburn if hot herbs do that to you. As for your diet, I'd look into that a lot more. Without a gallbladder, eating a lot of meat isn't a great idea. You should go more toward a vegetarian diet because, remember, you don't have a gallbladder and all forms of meat other than wild game have a lot of fat and it's fat you're going to have the problems with. Saturated fat isn't bad in and of itself, it's the form that's important -- fatty fish is high in fat but the body deals with it a lot better than it does meat. Beans and nuts and seeds are good sources of vegetable protein, and the mix of fiber, fat, and healthy carbs will go down better than meat. Whole grains are a good source of energy for you. Lots of veggies and certain fruits supply valuable antioxidants that protect your liver and prevent fat from oxidizing and clogging your blood vessels. I'd advise, lastly. that you consult again a good herbal and some good books on vitamins and minerals as well so you protect that liver. Which means, stop the vaping. I know, you like the nicotine, but your body doesn't, and your liver is a big part of what protects you from toxins and again, minus a gallbladder it has to work harder. Peace and good health.
Turmeric can be taken as a supplement to complement your regular healthcare regimen. You can also take it in the form of juice. There are many supplements available in the market, you can easily get them online.
I would also recommend you to please check with your doctor first to see if turmeric is right for you.
YOu can take turmeric mixed with milk. It is something my Indian friend told me about. Mix a bit of turmeric with some hot milk and you're good to go. It might taste a bit strong but is very beneficial for you
