As I learned from various material, it seems regular consumption of turmeric approx 3 to 5 grams create an good impact to human bodies, I would like to know the amount of daily consumption of 100 % Pure curcumin which contribute an effect to improve metabolism activity and immunity power.
Assuming 5% usage of Black pepper increases the bio availability of curcumin in body.

Curcuma's powder is about 60–70% carbohydrates, 6–13% water, 6–8% protein, 5–10% fat, 3–7% dietary minerals, 3–7% essential oils, 2–7% dietary fiber, and 1–6% curcuminoids. As you see, it has a high content of carbohydrates, but not all of it are sugars, because there is a high content of dietary fiber, that is a very important way to prevent many gastrointestinal diseases. The article @Dhifaf Zeki recommended you is very interesting. You can also check Wikipedia's data about Turmeric, and if you speak Spanish use that version of Wikipedia's article, that has other details that the English version doesn't have.
From a theoretical standpoint, the assumption that curcumin can be consumed daily in a specific dosage to enhance human health ignores the fact that this claim is based on extrapolations of data collected from model animals.
Some studies have demonstrated that curcumin is a safe and effective compound that exerts anti-oxidant, anti-inflammatory, anti-proliferative, pro-apoptotic and anti-cancer effects (https://pubmed.ncbi.nlm.nih.gov/26876915/; https://pubmed.ncbi.nlm.nih.gov/30871021/).
On the other hand, (1) this compound governs multiple intracellular targets, so it can change a lot in the human body; (2) its local concentration in the body induces cellular stress which can exceed the adaptive response and can lead to cellular senescence (CS) that is triggered by time-dependent activation of several signaling pathways; (3) curcumin is bad for our cells (https://pubmed.ncbi.nlm.nih.gov/31372798/).
Although CS is believed to be a barrier to cancer development, please remember that CS also promotes cancer (https://pubmed.ncbi.nlm.nih.gov/21321098/). Curcumin seems relatively safe and has low bioavailability, so you can eat it from time to time, and low doses, i.e. a teaspoon of curcumin per day, seem safe, as high doses (> 12,000 mg/day) might be toxic or cytostatic as they can inhibit sirtuins and AMPK (https://pubmed.ncbi.nlm.nih.gov/30871021/), but if someone says that you can eat it all the time and a given dosage (e.g. 8,000 mg/day) will improve your health and will enhance your immune function, please be skeptical about these far-fetched claims as they are scientifically ungrounded. The same thing is true for other panacea such as metformin, rapamycin or resveratrol (https://pubmed.ncbi.nlm.nih.gov/31773357/; https://pubmed.ncbi.nlm.nih.gov/32193711/; https://pubmed.ncbi.nlm.nih.gov/31595371/).
Just in case you want to know why curcumin is both good and bad.

This may help. Curcumin also needs to be ingested with 'spicy' compounds such as piperine (found in black pepper) to inhibit hepatic enzyme function and increase bioavailability.
