Although it is not the most common vitamin that you will come across in supplements or in the food you eat, vitamin A is usually associated with benefitting eyesight. Adding more carrots to your diet can increase your vitamin A intake, but don’t count on it to lower your eyeglass prescription.
B vitamins are commonly found in leafy green vegetables. The most common B Vitamins you’ll come across in food or supplements are B-12 and folate. They assist with energy levels, so if you often find yourself fatigued, you could be suffering from a B vitamin deficiency. It is difficult to get enough B vitamins without taking a supplement, so this is one of the first to consider adding to your regimen.
When choosing a B vitamin supplement, there are two important factors to note. First, B vitamins are water soluble—meaning, if you take a dose that contains more than your body can absorb, you will simply excrete the rest. For this reason, it is important to take two smaller doses a day, rather than one large dose. You should also make sure that any B vitamin supplement you take is in a “methylated” form. If it is not, your body will not be able to absorb it at all.
Vitamin C is closely associated with citrus fruits. It plays a role in a variety of cell processes and aids in general body functioning. Typically, you cannot get enough vitamin C from eating citrus fruit alone, so if you’re going to take any supplements, C is a good one to start with. The issue with vitamin C is that because it is so well-known, there are a lot of options when it comes to choosing a supplement. It is important to look for vitamin C with bioflavinoid. If it does not contain biofalvinoid, your body will not be able to absorb it.
Vitamin D is not actually a vitamin, but, rather a hormone. It is also one of the most important hormones in the human body because it helps prevent inflammation and reduces your chances of getting sick. You can’t get it through food, so the best way to boost your vitamin D levels is to spend time in the sun. Exposing your torso to the sun is especially effective because it is where absorption happens most easily. While this sounds like an appealing addition to your daily routine, it’s probably not realistic. The good news is, vitamin D supplements are fairly standard and don’t vary much from brand to brand—so, you don’t have to worry as much about getting an ineffective supplement.
K vitamins occur in two common forms. K-1 is important for newborn babies but not particularly important for adults. K-2 is the form that is crucial for preventing osteoporosis. When taken with vitamin D, it helps the body absorb calcium and promotes bone strength. It is yet another vitamin that you’ll find in dark, leafy greens.
