If you are out in the sun often, then your body naturally will make enough Vitamin D for you. Also, most dairy products and fish have Vitamin D. Although a lack of it can be very bad, you don't really need that much of it to ward off problems like osteoparosis.
Problems with too much Vitamin D often have to do with the body absorbing too much calcium (both found in fortified milk, which I have drank lots of my whole life), and the body ends up storing the extra calcium as deposits in the body (heart, lungs, kidneys, etc.). So I guess the key is to not over do it. Unless you don't get any D from sun or dairy/fish, then don't take any extra (or take very little like in a daily vitamin).
Now the tablets I assume are some sort of cod liver oil derivitive, which is another way of getting Vitamin D, so if you are taking the cod tablets, you DON'T need to also take more Vitamin D, since you get plenty from the tablet.
Cod liver oil is a great source of omega3 along w/Vit A & D. But once again, it is not taken today as much as years ago since there are much more vitamins and minerals in our foods than they had two or three generations ago.
I'd keep taking the cod pill as a supplement, but no other Vitamin D, especially in the summer.

Chemically, they're the same, but since your body actively produces Vitamin D by itself in sunlight, you are better off using this as a source of Vitamin D as it is easier to obtain than supplements (and is not artificially produced or packaged). Your daily dose of Vitamin D can be picked up by exposing the back of your hands to sunlight for 5 to 15 minutes, so if you go for a walk during the day and your forearms are uncovered, for example, that's more than enough Vitamin D. Height is genetically determined, so having lots of Vitamin D won't help if you have already hit the height you are supposed to be (genetically), but it is very beneficial to bone structure and strength if you are still growing, as Vitamin D helps your body utilize calcium efficiently. Correcting another post - Vitamin D does not help vision, that's Vitamin A.

Neither are bad as long as you don't overdo. Balance is important. Vit D is something that your body will make if exposed to sunlight enough, but most aren't. So, supplementation is good. But, the cod liver oil tablets (which I assume is what you are taking) should also have Vit D in them as well as Vit A. So, that should cover it. The CLO tabs are not bad, unless you are getting a brand that isn't tested for mercury. You want to make sure your fish oil is tested mercury free. Carlson's is a good brand for this. There are others, they will say on the label.

Cod liver oil has 1,360 IU of Vitamin D in one tablespoon which is more than 3 times the RDA. So if you are taking in a tablespoon of Cod liver oil per day you don't need to further supplement with Vitamin D tablets. Vitamin D is a fat soluble substance so it can build up and become toxic. Here are the side affects and warning signs:
Vitamin D toxicity can cause nausea, vomiting, poor appetite, constipation, weakness, and weight loss . It can also raise blood levels of calcium, causing mental status changes such as confusion. High blood levels of calcium also can cause heart rhythm abnormalities. Calcinosis, the deposition of calcium and phosphate in the body's soft tissues such as the kidney, can also be caused by vitamin D toxicity.
Sun exposure is unlikely to result in vitamin D toxicity. Diet is also unlikely to cause vitamin D toxicity, unless large amounts of cod liver oil are consumed. Vitamin D toxicity is much more likely to occur from high intakes of vitamin D in supplements. The Food and Nutrition Board of the Institute of Medicine has set the tolerable upper intake level (UL) for vitamin D at 25 μg (1,000 IU) for infants up to 12 months of age and 50 μg (2,000 IU) for children, adults, pregnant, and lactating women. Long term intakes above the UL increase the risk of adverse health effects.

Some cod liver oil capsules are fortified with vitamin A and D and contain 4,000 IU of vitamin A and 400 IU of vitamin D, so if you take one a day you don't need a vitamin D supplement or a vitamin A supplement.

Cod liver oil contains both Vitamin D and Vitamin A, so you don't need to take both. Vitamin A can be toxic at the levels present in cod liver oil, so stop taking the oil, Vit D is not toxic at the levels present in Cod Liver Oil.
Vit D is toxic in high amounts, but you would need to be taking over 40,000 IU per day for that to happen. Up to 2,000 IU per day is safe, corrent recommendations is 1000 IU per day for those living in Northern climate in the winter.
