Did you know that when we refer to vitamin D, we’re really talking about multiple types of vitamins? We’ve got vitamin D3 (the “sunshine vitamin”, also found in animal products), D2 (vegetable origin), and the “active” forms of the molecule. You’ve probably read before that we need this nutrient to absorb calcium, explaining its importance to our bones.
The truth is: vitamin D is also key to maintaining our immune system, nervous system, and muscles. How can you increase it if your doctor warns you about a deficiency? You can get this compound through your diet, but you could also spend time in the sun or try taking supplements. And I’ll bet you didn’t know that vitamin D now exists in liposomal form. You don’t know what liposomes are? Well, keep reading!
Key Ideas
- Vitamin D is essential for helping bones absorb calcium, among many other benefits. To increase how much of it you absorb, you can try changing your diet, spending time in the sun, and taking supplements.
- The issue is that sun exposure accelerates skin aging, and very few foods in our diet contain vitamin D. The good news? Technology has brought about a genuine revolution: liposomal supplements!
- Liposomal formulas are validated by the scientific community, but that’s not all. They also reach the bloodstream far more rapidly. We suggest Sundt Nutrition supplements – once you try them out, you won’t want any other!
Advice on Increasing Your Vitamin D
Has your doctor told you that your vitamin D levels are low? They’ve probably suggested ways to increase them: diet, sunshine, supplements. But what exactly should you eat, and what type of supplement is most effective? Never fear; we’re here to explain it all!
Idea #1: Diet
Vitamin D dietary intake nowadays is, on average, far below recommended levels. This is due to the fact that very few food sources which are naturally high in vitamin D exist (1). The foods with the most vitamin D include fatty fish and cod liver oil. Take a look at this table: (2, 3)!
| Food | Vitamin D Per 100 Grams | Grams Per Serving | Vitamin D Per Serving |
| Cod Liver Oil |
210 mcg (8400 IU) |
10 | 21 mcg (840 IU) |
| Eels | 110 mcg (4400 IU) | 75 | 82 mcg (3280 IU) |
| Tuna | 25 mcg (1000 IU) | 150 | 37 mcg (1480 IU) |
| Canned/Preserved Tuna, Albacore, Mackerel, Etc. | 20 mcg (800 IU) | 80 | 16 mcg (640 IU) |
| Royal Jelly | 20 mcg (800 IU) | 10 | 2 mcg (80 IU) |
| Smoked Salmon | 20 mcg (800 IU) | 100 | 20 mcg (800 IU) |
| Prawns | 18 mcg (720 IU) | 175 | 31.5 mcg (1260 IU) |
| Mustard | 10 mcg (400 IU) | 5 | 0.5 mcg (20 IU) |
mcg: micrograms, IU: International Units
Idea #2: Sunshine
Did you know that your body naturally produces vitamin D when exposed to sunlight? It seems like the ideal way, doesn’t it? If only things were so simple! Whether or not you’ve thought about it, continued exposure to the sun speeds up cellular aging and also makes you more susceptible to cancer. Consider the following facts:
- Ultraviolet (UV) Radiation. Ultraviolet radiation is essential for our bodies because it promotes vitamin D production. However, UV rays penetrate the deepest layers of our skin. As a result, our skin gradually loses elasticity and begins to wrinkle. In other words, large doses of UV cause premature aging (4).
- Summertime. During the summer, five to fifteen minutes of sun exposure per day suffice to reach recommended vitamin D levels. Beyond that time limit, you should be using sunscreen (4). Incidentally, getting sunshine through a glass surface or window is not effective.
- The Sunscreen Problem. According to some studies, sunscreen may reduce the skin’s ability to produce vitamin D. (However, according to other experts, this decrease in production may be less than expected.) In any case, we still can’t neglect the sunscreen if we’re going to spend time in the sun. Your skin will thank you (5)!
- Vitamin D Reducing with Age. Experts’ studies have also indicated that the skin’s production of vitamin D from solar UV rays decreases with age. This is due to lifestyle change factors, such as wearing more clothing and spending less time outdoors (5).
- Pollution’s Effect on Vitamin D. Air pollution leads to increased ozone and nitrogen dioxide levels, which absorb UV rays. Consequently, pollution is a risk factor for hypovitaminosis and vitamin D deficiency (5).
Idea #3: Liposomal Supplements
Did you know that taking vitamin D supplements can reduce the risk of dying from cancer by up to 16% (6)? There are many different types of vitamin D supplements out on the market, but what if we were to tell you that liposomal supplements are by far the most effective? You’d probably ask our reasons for this claim, and we’ll explain them right now.
Liposomes are a type of capsule fabricated from organic materials. Because their composition is very similar to our own cells, they provide vitamins a protective covering which improves their absorption (7). Liposomal formulas have proven their effectiveness in the pharmaceutical world, (8) and now they constitute a revolutionary change in the dietary supplement field.
For all these reasons, we suggest Sundt Nutrition vitamin D supplements: a formula which allows truly efficient absorption of nutrients. Let’s learn more:
- Liposomal formulas are validated by scientific research. What’s more, studies show that nutrients are more bioavailable when administered through liposomes, compared to vitamins not in liposome capsules (7).
- Founded on liposomes. Liposomes keep the substances they transport from making direct contact with the intestinal environment, which allows them to move nutrients to the cells and tissues which need them most. They’ll reach their target ready to carry out their jobs, safe from breakdown and degradation (8).
- More bioavailability. In other words, a higher proportion of active ingredients actually reach our bodies when we ingest them through liposomes.
- Cost-effective. Because Sundt’s liposomal supplements offer higher bioavailability, their cost-to-performance ratio is far superior to other types of supplements.
Why Do I Need Healthy Vitamin D Levels?
Vitamin D deficiency is common and widespread around the world. It’s associated with higher risk of cancer, infectious disease, heart disease, and death (9). For all those reasons, it’s obvious that our bodies require this nutrient, but how much do we need per day? Why is it so crucial? Take notes, because we’re about to answer those questions.
What Is Vitamin D and How Much Do I Need Per Day?
Vitamin D, or calciferol, is a liposoluble vitamin (meaning it’s dissolved in fat). We generally obtain it through vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Also called the “sunshine vitamin”, dietary supplements offer a valid way to absorb it in addition to food.
The dietary origins of D2 are vegetable-based, while D3 comes from animals and can also be produced in our own skin when exposed to the sun. How much vitamin D do we need every day? As this table shows, it depends on your age (10):
| Age | Recommended Daily Intake (RDI) |
| Infants (0-12 months) | 10 mcg (400 IU)* |
| Children (1-13 years) | 15 mcg (600 IU) |
| Adolescents (14-18 years) | 15 mcg (600 IU) |
| Adults (19-70 years) | 15 mcg (600 IU) |
| Elderly (71 and up) | 20 mcg (800 IU) |
| Pregnant and breastfeeding women | 15 mcg (600 IU) |
*The RDI is expressed in micrograms (mcg) and International Units (IU)
What Is Vitamin D Used For?
In supermarkets, you’ll typically see milk and other products fortified with this particular nutrient – but why? Is it really that difficult to obtain? Keep reading, and we’ll go over the basic functions of vitamin D in the human body.
- Benefits our bones. Vitamin D is important for our bones’ normal growth and development, since it helps us absorb the calcium in food (11).
- Essential for muscles. In fact, this vitamin is key to muscle movement.
- Necessary for the immune system. Without vitamin D, our bodies cannot combat the viruses and bacteria which cause colds, flu, and infections (12).
- Prevents Osteoporosis. As we get older, our bones gradually lose density and become more fragile, causing a condition known as osteoporosis. If we lack enough vitamin D, our bodies won’t absorb calcium, hence its importance (10).
In case what you just read wasn’t enough, there are studies (13) which suggest that vitamin D deficiency contributes to high blood pressure and atherosclerosis (a disease which affects the arteries leading to the heart).
Our Conclusions
Does your immune system need strengthening? Have you not managed to include enough vitamin D in your diet? Are you not getting enough sun? We suggest Sundt Nutrition’s supplements – a genuine revolution in the dietary supplement field thanks to their use of liposomal technology. Liposomes mean higher bioavailability – in other words, the amount of nutrients which reach our bodies intact.
Plus, if you have coeliac disease, you’ll have no problem whatsoever with these gluten-free supplements. That’s not all: Sundt Nutrition products are made of completely natural, sugar-free ingredients. We’re convinced that once you try our liposomal supplements, you’ll come back for more!
