Vitamin D3 Review
Vitamin D3 is a potent vitamin supplement to overcome the deficiency of vitamin D. It’s one of several products sold by California company Sports Research. They distribute 19 popular supplements which sometimes sell out. The company is best known for the workout cream Sweet Sweat, originally developed in 1977. They seem to be greatly concerned with overall health and making sure people exercise properly. For this product, in particular, it doesn’t seem aimed at general use. It’s for people who need a supplement of very very high potency.
Vitamin D3 contains the following ingredients: Vitamin D3, Organic Extra Virgin Coconut Oil, Softgel Capsule (kosher gelatin, kosher vegetable glycerin, purified water)
People should not take more than the serving size (one capsule) listed on each bottle of this product. One capsule a day is the absolute maximum you should have. Any more than that, and you risk vitamin D toxicity. Sometimes there’s too much of a good thing. The coconut oil in this product also alleges that it increases absorption of D into the body, making abuse a possibility.
Vitamin D is necessary for healthy bones. It promotes calcium absorption and maintains levels. Without sufficient amounts of this vitamin, your bones could become thin and brittle. It’s an important part of preventing osteoporosis. It also reduces inflammation and modulates cell growth while helping neuromuscular and immune function. The Food and Nutrition Board at the Institute of Medicine of The National Academies recommends that most people take in 600 IU of vitamin D daily. You can get away with less, but many Americans have a massive deficiency of vitamin D. Up to 50 percent of the population is thought to need more D. The less sunlight you see, the more you need. Even an average person may need 1000 IU a day.
- 5000 IU of vitamin D, which is highly effective for people with deficiencies. Prescription pills of vitamin D are often 3000 IU, and much more expensive than this product.
- Includes extra virgin coconut oil for extra taste and health benefits. Capsules are also Kosher.
- Some people think the capsules are too large. 5000 IU of vitamin D might be more than most people want, since taking even 2000 IU a day can bring your D levels up to normal.
- Many people will prefer a smaller bottle, as 360 capsules is a lot. Most won’t need that much to combat a vitamin D deficiency.
This is one of the top 10 vitamin D3 supplements on Amazon with only 3 percent of the reviews being negative. It’s easy to see why, because for the quality and value, there are few products which can match this one. It’s high potency, with bottles giving you almost an entire year’s supply for a low price. You only need one capsule a day, and there’s coconut oil to help with absorption and taste. Do note that cloudy capsules is normal, simply because of the coconut. To eliminate a vitamin D deficiency fast, look no further than this product from Sports Research.

Is Vitamin D3 Right For You?
Vitamin D3 is a high potency vitamin D supplement. It’s distributed by Sports Research, a company from San Pedro, California. They appear to have been founded in 1980. Their products ship with special numbers that allow you to check results of third party testing and certificates of analysis. This creates a lot of transparency with the company, as you can be assured of quality and content of your supplement orders. Anyone facing a deficiency of vitamin D should look into this product instead of getting a prescription for D3.
Ingredients of Vitamin D3
Vitamin D3 includes the following ingredients: Vitamin D3, Organic Extra Virgin Coconut Oil, Softgel Capsule (kosher gelatin, kosher vegetable glycerin, purified water)
Effectiveness of Vitamin D3
Vitamin D, “the sunshine vitamin,” is supposed to be effective for calcium absorption and maintaining strong bones and teeth. It’s an essential vitamin most people don’t get enough of. This product contains 5000 IU of vitamin D3 (as cholecalciferol from Lanolin). The Tolerable Upper Intake Level (ULs) for anyone over the age of 9 is 4000 IU a day, so this product is only for people with severe deficiencies of vitamin D.
There are health risks from excessive vitamin D, unlike water soluble vitamins like B12. Vitamin D toxicity can cause various symptoms that change from person to person. This includes anorexia, weight loss, polyuria, heart arrhythmias, and kidney stones. Too much vitamin D can inflate the amount of calcium in your blood, which can cause internal damage. Specifically the heart, blood vessels, and kidneys. It is very unlikely you’ll experience vitamin D toxicity when taking less than 10,000 IU a day, but the research isn’t too clear. When in doubt, ask your doctor how much vitamin D you need daily. Long term overuse of D increases health risks and may cause interactions with medications like weight loss drugs and steroids.
Vitamin D3 Price
There are 360 capsules in each bottle, making this amazingly cheap. You only need one capsule a day at most, although your doctor will tell you much vitamin D you need to start taking. If you need 5000 IU a day, this is inexpensive, and will often be a first choice. Sports Research does offer a 90 day money back guarantee. They’re confident in the level of satisfaction people will have with their supplement. The price is reasonable, especially on sale, and there’s a good chance you can get free shipping. Even if shipping isn’t free, this price is almost unbeatable for a one year supply.
Does Vitamin D3 Work?
One capsule of this supplement gives you enough vitamin D to catch up with your dietary needs quickly. It’s slightly above the maximum recommended amount of vitamin D people should have on a daily basis. Reviews are overwhelmingly positive and this is definitely a great product. It’s high quality and low priced, sold by a company with a decent reputation. Regular supplementation of vitamin D can increase bone health, lift your mood, and more. This is one of the best products to look at if you need something to eliminate vitamin D deficiencies.
