Criteria Used for Evaluation

Effectiveness

We all know that any type of supplement can be costly. The last thing you want to do is to spend a large amount of money on a product that you think is going to be quality, only to find out that it’s subpar. The same goes for purchasing your vitamin D supplements. If this is something that you intend to use regularly, then you should make sure that it’s appropriate for your health, and that it’s going to do what it’s supposed to do. These are usually an option for people that have to work all day, or for those who work midnight shifts. There are plenty of situations that can deprive you of a healthy amount of vitamin D and it’s essential to make sure that you’re getting everything you need to stay at the top of your game.

Individuals who are over the age of 50 (and especially over the age of 70) are at an increased risk for naturally decreasing Vitamin D levels. Other signs of potential Vitamin D deficiency include overall malaise and fatigue, achy joints and bones, profuse head sweating, and gastrointestinal issues like bloating, gas, nausea, and just general stomach pain.

Some people still believe that it’s a good idea to get all the vitamin D they need from sunlight. Unfortunately, this can lead to unnecessary UV exposure that can result in skin cancer. It’s always better to try to adjust your diet to increase your vitamin D levels rather than spending an excessive amount of time in the sun. In reality, the sun provides a tiny percentage of your overall vitamin D intake. The majority of what you’re getting is coming from your diet, and this is why supplements may be a better idea. There’s no reason to go out and damage your skin when there are plenty of healthy alternatives.

Most of us work full-time or part-time jobs, go to school, have families and extracurricular activities and other priorities that take up our days. Not to mention, depending on where you live, you might not even see the sun for six months out of the year (hey there, Alaskans!) or it might be just too bitter and cold to step outside with bare skin to soak up the rays. It is where a Vitamin D supplement can come in handy, but again, if it does not boost your Vitamin D levels, then it is not going to do you any good.

When you regularly take a Vitamin D supplement, you will likely start to develop stronger bones and healthier teeth. It is because one of the main functions of Vitamin D (and thus, proof of effectiveness) is that it helps the body take in and absorb calcium that is in the intestines, which would otherwise be excreted through the kidneys. But besides bone health, Vitamin D can be one of your greatest defenses against overall fatigue and illness (especially illnesses like the common cold and the flu) and can keep serotonin levels balanced and your mental health on track. Luckily, we took all of these health benefits into consideration when we chose which Vitamin D supplements were best. The supplements included in our list will effectively help you increase and maintain healthy bone health, show off a beautiful smile, combat tiredness, and sickness even during the long winter months when everyone around you seems to be ailing, and help keep you happy!

Product Purity

As runners and athletes, we're concerned and conscious of what we put in our bodies which is why we looked at the purity of all the products on our list. It might be surprising, but the vitamin D3 in vitamin D supplements actually comes from the lanolin in sheep's wool, and sometimes from fish oil although that tends to be quite a bit more expensive. That's why you'll also find some vegan supplements. The vitamin D in these products is vitamin D2 and typically comes from lichens. Vitamin D2 and D3 are both very effective at raising your levels of vitamin D, but D3 will keep those levels elevated for a more extended amount of time than D2 and thus be much more effective. So unless you are indeed a vegan we recommend taking a vitamin D3 supplement instead of a vegan sourced vitamin D2. There are some vegan vitamin D3 supplements available, and we included one on our list, they tend to be rather expensive.

Value

When creating our list of Vitamin D supplements, we paid close attention to what each supplement costs. A daily supplement routine should not cost you a ton of money. In short, you should not have to sacrifice health just because you live on a limited budget. Our list of Vitamin D supplements run a bit of a wide range of price (mostly due to what ingredients are contained in the supplement) ranging from just eight dollars a bottle up to $32. However, more important than just total cost of each bottle of pills is the number of pills contained in each bottle because that will give an indicator of how long each bottle will last (and thus, how far you can stretch your dollar). On average, you can find around 100 capsules in each bottle, though some are as much as 200 and over.

The number of pills in each bottle will give you an idea of what the per serving cost will be (which is the REAL indicator of value). Per serving costs on our bottles range from just 2 cents per serving up to nearly 35 cents. However, the price is only one piece of the puzzle. We want you to be getting the very best VALUE for your money, which is determined by cost but also by several other factors.

Things that give value to a supplement are how long the pills will last, how much Vitamin D is contained in each tablet, the quality of ingredients used to create the supplement and how easily taking the supplement can fit into your schedule, etc. Considering all of these components of ‘value’ is what helped us narrow down our list to the ten Vitamin D supplements we have included here, so you can be sure that you are getting the best overall value for your money.

Ease of Use

Can you easily swallow pills? Some adults, and especially children, need to take medicines and drugs only in liquid or chewable forms because they cannot swallow pills – either due to a personal aversion or are very sensitive to the size and have trouble taking any pills too large. If you prefer a liquid or chewable tablet, then our list has some great options for you – particularly the Nature Made Adult gummies and the Biotics Research Bio-D-Mulsion Formula that is a liquid.

Potency

You need 600IU per day of vitamin D. This is a number though, that can vary depending on what activities you do and how much you are naturally exposed to the sun in your daily routine. You can take the supplement directly or in a formulation included in a multivitamin that you can get over the counter. For your body to absorb the most value the supplement can offer, you should take it with your most substantial meal of the day. It is best to ingest it when you have eaten a food source containing good fats, which most often, tends to be your most substantial meal of the day. Don’t take it on an empty stomach; it will be less effective.

You can be sure you are getting some of the purest vitamin D3 available. There isn’t even any preservatives or coloring to them. Pretty basic natural stuff, helping to keep you strong.
