最佳维生素C补充剂:买方指南

维生素C与大量健康益处有关,例如提高抗氧化剂含量,支持健康血压和增强免疫力。Unfortunately, humans do not naturally produce vitamin C like other mammals, and it’s water-soluble, so it has to constantly be replenished. Luckily, there are options!

If you need more C in your life, but have a hard time consuming enough vitamin C-rich foods in your diet, we’ve chosen some of the best vitamin C supplements on the market. 

Vitamin C Benefits

Vitamin C is an essential vitamin and strong antioxidant that can strengthen your body’s natural defenses and its need to produce your natural killer cells. It can help protect against oxidative stress put on the body and neutralize free radicals (1). This can help your immune system overall.

Vitamin C can help promote a healthy inflammation response. Studies show that consuming more vitamin C may increase your blood antioxidant levels by up to 30 percent (2, 3).

Vitamin C can help support normal blood pressure levels by relaxing the blood vessels that carry blood from the heart (4).

Vitamin C can help support the skin’s healthy aging by promoting collagen product, an important protein for the skin and joints. Both topically, and internally, research has shown it can help the skin’s overall appearance and with wound healing (5, 6, 7).

Vitamin C is great for heart health as well by helping protect against damage to the cells in blood vessel walls that can lead to cholesterol issues (8). It can also help with lung function (9) and help with gastric issues caused by acid or bacteria problems (10).

Many sources suggest for optimal levels to try and get 1,000 mg a day for optimal overall benefits (11, 12). Always make sure to check with your doctor before taking any new supplements.

Signs of a Vitamin C Deficiency 

There can be many different signs of a vitamin C deficiency. Some of the signs include, but are not limited too, impaired wound healing, bleeding gums, weight gain, dry skin, malaise and fatigue or lethargy, weakened immune system, irritability, chronic inflammation and oxidative stress, scurvy, gingivitis, internal bleeding and more (13, 14).

It’s also good to note that deficiencies in bioflavonoids, which are usually found together in vitamin C supplements, may cause easy bruising, varicose veins, circulation issues, and hemorrhoids (15).

How to Choose a Vitamin C Supplement

When looking for a vitamin C supplement, there are a few different kinds out there depending on what your needs are. The most basic version of vitamin C is ascorbic acid by itself, which would be your best value.

Vitamin C and bioflavonoids are found together in nature, such as citrus fruits, so it’s always good to have bioflavonoids in a blend because they help with the assimilation of vitamin C, and they help with the integrity of your veins and capillaries. Most people are deficient, especially females or those who do not eat citrus. Look for bioflavonoids such as hesperidin, rutin, rose hips, acerola, diosmin, quercetin, lemon, and general citrus bioflavonoids added.

For those with sensitive stomachs to citrus, acidic foods, ascorbic acid, or who have acid reflux, upset stomach or diarrhea, I would go with a buffered form of vitamin C such such as calcium ascorbate (trademarks such as Ester-C), sodium ascorbate, or magnesium and/or zinc ascorbate. These buffered forms add a mineral molecule to make the vitamin C non-acidic and easier on the stomach. Some conflicting research shows that these forms may be absorbed better, although more research is needed, because some studies show it has the same absorption as ascorbic acid (16).

If you are looking for better absorption into the cells, or if you have malabsorption issues (or severe immune issues), I would go with a liposomal vitamin C or ascorbyl palmitate, a fat soluble vitamin C ester. Liposomal vitamin C is encapsulated in a lipid base that makes the vitamin C fat soluble instead of water soluble, for better absorption into the cells. It usually comes in a capsule or high dosage liquid form (17).
