Ultra Vitamin D3* 2000 IU (50µg)

Extra Strength Vitamin D3 Tablets

Ultra Vitamin D provides extra strength vitamin D, a nutrient that plays a truly remarkable role in the body and is important for many areas of health. It not only contributes to the maintenance of normal bones and teeth but is also known for its role in supporting normal function of the immune system, normal cell division and normal muscle function.

Vitamin D is synthesized by the body on exposure to sunlight. However, many areas of the world receive insufficient sunlight and even in sunny areas, many choose to limit their exposure due to the negative health effects of excessive exposure to the sun's UV rays. These factors have led to widespread low vitamin D levels in many parts of the world.

Many national governments now recommend vitamin D supplementation for the entire population, due to the many benefits of this key nutrient. The UK Department of Health recommends that everyone (including pregnant and breastfeeding women) should consider taking a daily supplement containing vitamin D especially during the autumn and winter. 

What is Vitamin D?

Vitamin D is a fat soluble vitamin found in foods such as mushrooms, oily fish, butter and egg yolk. Vitamin D has functions and benefits that are probably more wide ranging than any other vitamin.

There has been huge renewed interest in vitamin D recently, with new global research showing that the health benefits of this nutrient stretch beyond bone health. There is increasing evidence for the beneficial effects from dietary vitamin D which has shown benefits for its contribution to:

Normal function of the immune system
Maintenance of normal bones and teeth
Normal absorption and utilisation of calcium and phosphorus
Normal muscle function
Normal blood calcium levels
The process of cell division

For adults over the age of 60, it has also been shown that a daily vitamin D intake of 20µg or more from all sources helps to reduce the risk of falling associated with postural instability and muscle weakness. Falling is a risk factor for bone fractures among men and women 60 years of age and older.

Vitamin D3 The Preferred Bioactive Form

Ultra Vitamin D provides effective levels of the preferred form of vitamin D3 (cholecalciferol). Ultra Vitamin D provides British Pharmacopoeia quality vitamin D3. D3 is the preferred form of vitamin D because it is the specific form made in the human body and therefore more effective than D2 which is found in some supplements.

Vitamin D - the sunshine vitamin

While our bodies manufacture vitamin D on exposure to sunshine, the levels in many countries is so weak during the winter months that our body makes little or none at all, meaning that dietary supplements are often the best way to safeguard intakes of vitamin D. Many populations, including the majority of those in Europe, require an additional dietary source of vitamin D to achieve and maintain an adequate status of this important vitamin.

In addition, the body does not generate vitamin D when sitting behind a glass window, whether in your car or at home, because these UV rays cannot penetrate glass to generate vitamin D in the skin. Sunscreens, even weak ones, while essential to protect the skin, can affect the body's ability to generate vital vitamin D.

Vitamin D in the diet and health benefits

Vitamin D is naturally present in some foods (e.g. oily fish such as herring, sardines, fish liver oils, eggs, butter) and in a few foods that are fortified (e.g. margarine, some cereals, some yoghurts). Vitamin D is fat soluble, therefore advice to eat lower fat diets may contribute to reduced intakes from foods and hence dietary supplementation may be needed. In the UK, an average diet provides 3-4 µg of vitamin D per day and only a little more if oily fish is consumed.

There are several reasons why vitamin D supplementation may be especially recommended, including:

Government health advice to reduce sun exposure which can mean less Vitamin D is produced naturally by the body.
Reduced sun exposure in some groups of the population e.g. older people, those who cover their skin, certain occupations, medical reasons and those with darker skin tones (as greater skin melanin content can reduce the skin's production of vitamin D).
Increased requirement at certain life stages e.g. the elderly population, whose skin may not be able to synthesise vitamin D as effectively.
Those with increased dietary intolerances (e.g. lactose and dairy) or allergies.
People who are on a diet.

*Ultra Vitamin D provides D3, which is preferred form of vitamin D.

Who can live without slime great stuff and a good price. 👍
Style: 32 oz
If anyone has an outdoor anything that takes air. You should never be caught without this stuff. It seals your tires on almost anything and it lasts longer than you would expect. It’s easy to use and easy to clean up after using it. It will work well for anything that is supposed to hold air. Great product.

Title: Reliable, Easy-to-Use, and Worth Every Penny
Style: 32 oz
I’ve been using Slime tire sealant for my fat tire e-bike, and I can say with confidence that this product delivers exactly what it promises. The application is simple, the results are consistent, and the peace of mind it provides is invaluable. For anyone who rides regularly — whether for commuting, recreation, or deliveries — this is a product that pays for itself many times over. The first thing I appreciate about Slime is how easy it is to install. The bottle is well-designed, the instructions are clear, and the process takes just a few minutes. You simply deflate the tire, remove the valve core, squeeze in the recommended amount, reinstall the valve core, inflate, and spin the wheel to distribute the sealant evenly. No special tools, no mess, and no guesswork — just a straightforward, user-friendly process. Performance-wise, Slime does exactly what it’s supposed to do: seal punctures quickly and effectively. I’ve had nails, thorns, and sharp debris puncture my tires while riding, and in every case where the leak was within the tread area, Slime sealed it instantly. There’s something incredibly reassuring about hearing that faint hiss of air for a second, then watching it stop as the sealant does its job. It’s a real-time reminder that this product is actively protecting you from being stranded. What sets Slime apart from other sealants I’ve tried is its durability. Once applied, it stays active inside the tube for months, ready to respond to new punctures as they happen. It doesn’t dry out quickly, it doesn’t clump up, and it doesn’t cause balance issues with the tires. For someone who rides almost daily, that reliability is a huge plus. Another thing I respect about this product is that it’s non-toxic and environmentally friendly. If a bit of sealant escapes during a repair, I don’t have to worry about it harming the environment. It’s also water-soluble, making cleanup easy if I ever need to replace a tube or tire. That attention to safety and sustainability shows that the company isn’t just making a great product — they’re doing it responsibly. The value for the price is excellent. One bottle goes a long way, and when you factor in the cost of replacing tubes, paying for roadside repairs, or even the inconvenience of being late because of a flat, Slime is an investment in both savings and peace of mind. For delivery riders like me, it’s especially valuable — every flat avoided means another day of work uninterrupted. In short, Slime is one of those rare products that I can recommend without hesitation. It’s easy to use, effective, long-lasting, and backed by a company that clearly understands the needs of cyclists and e-bike riders. It has already saved me from countless headaches, and I plan to keep a bottle on hand at all times. If you ride regularly and haven’t tried it yet, you’re taking an unnecessary risk — this is one of the best preventative tools you can add to your maintenance kit. Verdict: Five stars for performance, ease of use, and overall value. Slime is a must-have for any serious rider who values reliability and wants to keep rolling no matter what’s on the road.

Slime is good, pump is a disaster
Style: 1 gal, Style: 1 gal
The only reason I am giving this a 4 star(not zero) rating is the slime itself. The actual pump on the 1 gallon canister is awful. It makes so much mess, so I do not know whether I pumped the slime into the tubes or it all just spilled out of the base of the pump. The bottles worked great, but this time I needed to use more slime for a bunch of tires. What a slimy mess that was. Very poor pump design. Only after I spilled who knows how much of the slime, I finally washed it and was able to see the problem. The cap at the base of the pump got unscrewed and let all the slime lose. I screwed it back up and this should fix the mess next time I use it. Just a heads if someone encounters the same issue.

Style: 1 gal
This stuff is awesome. If you have tractor tires, ATV tires, bike, tires, hell, any tires that hold air. This stuff is awesome. Awesome. Awesome. It does not work for highway vehicles, i.e. Cars and truck trucks. But anything else it’s great. Dollies, air compressors, wheelbarrows, the stuff is awesome dude.
