[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] A porphyrin iron formula milk powder, which is composed of the following components by weight: 50-60 parts of raw cow's milk, 1-2 parts of calcium, 1.6-3 parts of porphyrin iron, 2-6 parts of fruit and vegetable extracts, 4-6 parts of red date extracts, 1.5-2 parts of donkey-hide gelatin extracts, 0.5-1 parts of glucose, 0.3-0.6 parts of vitamin E, 1-2 parts of coenzyme Q10, 1.5-3 parts of motherwort extract and 0.3-0.5 parts of chuanxiong extract;

[0027] Among them, raw cow's milk contains whey protein, casein and lactose. Whey protein is rich in 8 essential amino acids for the human body, and the ratio is reasonable, close to the human body's demand ratio. It has high nutritional value and is easy to digest and absorb. Casein is a phosphorus-calcium binding protein. It is relatively slow to digest and absorb in the human intestine. Under the action of gastric acid, it will form curds, which makes the milk stay in the stomach for a longer time, increase satiety, and help the absorption of minerals such as calcium. It is of great significance for the protection of bones. Lactose can regulate intestinal flora in the intestine, promote the growth of beneficial bacteria such as bifidobacteria, inhibit the reproduction of harmful bacteria, and help to establish a healthy intestinal environment. Lactose can also promote the absorption of minerals such as calcium, iron, and zinc, which is beneficial to maintain bone health;

[0028] Calcium is an essential mineral for the human body. It is important for maintaining the health of bones and teeth. It is also involved in physiological functions such as muscle contraction and nerve conduction.

[0029] Porphyrin iron is an organic iron compound, which is composed of a porphyrin ring and an iron ion. This structure makes porphyrin iron easily absorbed by the human body, and it is an ideal iron supplement. Compared with other iron supplements, porphyrin iron generally does not produce rusty taste, nor does it cause great irritation to the stomach and intestines. It plays an important role in the treatment of iron deficiency anemia. It can supplement iron for the human body, and iron is a key raw material for the production of hemoglobin, which helps to increase the level of hemoglobin.

[0030] Fruit and vegetable extracts are substances extracted from fruits and vegetables through physical, chemical or biological techniques. In terms of extracted ingredients, they contain a variety of nutrients, such as vitamins (such as vitamin C extracted from citrus fruits), minerals, flavonoids (existing in apples and other fruits and vegetables, with antioxidant effects), polyphenols (resveratrol in grape skins is a polyphenol) and other bioactive ingredients. They can provide concentrated nutrients and play a health-care role;

[0031] Red dates are a good product for replenishing qi and blood. They are sweet, warm in nature, and enter the spleen, stomach, and heart meridians. In terms of nutrients, red dates are rich in protein, fat, sugar, carotene, B vitamins, vitamin C, vitamin P, calcium, phosphorus, iron and other nutrients, among which iron plays an important role in replenishing blood.

[0032] Donkey hide gelatin extract retains many effective ingredients of donkey hide gelatin, mainly collagen, which is beneficial to skin health, can increase skin elasticity and reduce wrinkles. It also contains a variety of amino acids, such as glycine and proline, which can play a role in replenishing blood to a certain extent and help improve anemia symptoms. In addition, trace elements and other ingredients in it also have the potential to help enhance the body's immunity;

[0033] Glucose is a monosaccharide and an important energy source for the human body. In the human body, glucose can be directly absorbed and utilized for physiological activities such as metabolism and exercise.

[0034] Vitamin E has antioxidant function, which can protect human cells and tissues from damage by free radicals, especially red blood cells and nerve cells, and also has certain benefits for skin health.

[0035] Coenzyme Q10 is a fat-soluble quinone compound with antioxidant properties. It can remove free radicals, reduce the damage of free radicals to cells, protect cell health, and thus help slow down the aging process. It is also important in maintaining heart health, assisting the energy metabolism of heart cells and improving myocardial function.

[0036] Motherwort extract is an active ingredient extracted from the plant Motherwort, which can increase coronary flow and slow down heart rate, and has certain benefits for the cardiovascular system. At the same time, Motherwort extract also has certain anti-inflammatory effects, can reduce inflammatory reactions, and may play an auxiliary role in the treatment of some gynecological inflammations;

[0037] Chuanxiong extract is extracted from the Chinese herbal medicine Chuanxiong. Chuanxiong is often used to promote blood circulation and qi, and has a significant effect of dilating blood vessels. It can effectively improve blood circulation in the brain, for example, it can be used to relieve headaches caused by vasospasm. In terms of cardiovascular, it has a protective effect on the heart. By increasing coronary blood flow, reducing myocardial oxygen consumption, and reducing the scope of myocardial infarction, it has a certain auxiliary value in the treatment of cardiovascular diseases such as coronary heart disease. In addition, Chuanxiong extract also has a certain anti-platelet aggregation effect, which can reduce blood viscosity and reduce the risk of thrombosis.
