What is Spermidine?
Spermidine is a vital, natural substance that is found in the human organism as well as in foods such as wheat germ, soybeans and nuts. In our Cell Boost formula, spermidine is derived from high-quality wheat germ extract. The manufacturing process makes it gluten-free.

How does Spermidine promote healthy aging?
Increased intake of spermidine protects against cardiovascular disease, cancer, and metabolic disease, and preserves memory. This is because spermidine stimulates autophagy. Autophagy is the body's cell rejuvenation and clean-up process that breaks down or repairs damaged components of the cell. This keeps cells healthy and protects them from disease. Autophagy can also be stimulated through fasting. Both supplements with spermidine and regular periods of fasting are therefore particularly relevant with advancing age, as autophagy declines over time(S, S). In addition, supplementation with spermidine has been shown to prevent hair loss and strengthen hair growth(S, S).

What is the potential of spermidine to increase life expectancy?
A population study in humans has shown that a diet rich in spermidine is associated with increased life expectancy(S, S).
A study in mice found that increased spermidine intake from advanced age (70% of life expectancy) increased life expectancy by about 7% on average and from young age (16% of life expectancy) increased life expectancy by about 11%(S).

What is the dosage of spermidine in Zell Boost?
Our Zell Boost contains an optimally adjusted daily dose of 1mg of spermidine from high-quality wheat germ extract, for both men and women.

What are the side effects of spermidine?
The EFSA has classified a daily dose of up to 6 mg as safe. There are no known side effects from ingesting spermidine. Spermidine is a naturally occurring substance in the body.

What is niacinamide?

The essential vitamin B3 derivative for cellular energy and longevity Niacinamide, also known as nicotinamide, is a water-soluble form of vitamin B3 and an essential precursor of the molecule NAD+ (nicotinamide adenine dinucleotide). NAD+ is present in every cell of the human body and plays a central role in numerous biological processes.

How does niacinamide promote healthy aging?

NAD+ is the fuel of mitochondria, the power plants of our cells. NAD+ is essential in converting food into energy and plays a critical role in maintaining DNA integrity. The molecule thereby ensures healthy cellular function to protect our bodies from aging and disease and to enhance our muscle strength(S, S). For maximum effectiveness, niacinamide should be combined with TMG (trimethylglycine), as both act synergistically as NAD+ boosters(S).

What is the potential of niacinamide to increase longevity?

Without adequate NAD+ levels, our cells are unable to produce energy. As we age, NAD+ in the body declines (at age 50, levels are still about 50%; at age 80, levels are only about 1-10% compared to young adults).

Supplementation with a NAD+ precursor such as niacinamide, which is converted to NAD+ by the body, helps maintain NAD+ levels in the body and decelerate the cellular aging process(S, S).

In mammalian studies, NAD+ boosters have been associated with increased longevity(S). For example, even in older mice, a 5% increase in life expectancy was shown when NAD+ boosters were taken only in the last eighth of their lives(S).

What is the dosage of niacinamide in Zell Boost?

Zell Boost for women contains 240 mg of niacinamide.

Zell Boost for men contains 300 mg of niacinamide.

What are the side effects of niacinamide?

EFSA has classified a daily dose of up to 900 mg as safe. Studies show that up to 3 g per day does not cause side effects. Unlike other forms of vitamin B3, niacinamide does not trigger the unpleasant flush reaction.

What is betaine?

Trimethylglycine, also betaine or TMG for short, is a molecule produced by the body. However, it is also found in foods such as broccoli, beet and spinach.

How does betaine promote healthy aging?

Betaine plays an essential role as a methyl group donor that is instrumental in controlling gene expression. Considering that our DNA contains the blueprint for all cells in our organism, the targeted deactivation of certain functions becomes more important. In this way, a cell can identify whether it should be a skin cell or a brain cell(S).
Another significant aspect of betaine is its ability to effectively lower homocysteine levels in blood plasma. This reduction is highly relevant, as elevated homocysteine levels are considered a trigger for cardiovascular disease and stroke(S, S).

Research also illustrates that betaine may exert a beneficial effect on various chronic diseases, including obesity, diabetes, cancer, and Alzheimer's disease, due to its anti-inflammatory properties(S).

It should be noted that NAD+ boosters such as niacinamide should always be taken in combination with betaine, as these boosters cause consumption of methyl groups(S).

What is the dosage of betaine in Zell Boost?

Zell Boost for women contains 120 mg of betaine.

Zell Boost for men contains 150 mg of betaine.

What are the side effects of betaine?

EFSA has classified a daily dose of up to 400 mg as safe. Betaine is a naturally occurring molecule in the body.

What is hyaluronic acid?

Hyaluronic acid is a naturally occurring molecule that is essential for keeping your skin hydrated and your joints supple. Although hyaluronic acid is often found in anti-aging cosmetic products, studies show that it also has impressive effects from the inside out as a dietary supplement.

How does hyaluronic acid promote healthy aging?

Taking oral hyaluronic acid has been shown to minimize skin wrinkles and improve overall skin condition(S). In addition, hyaluronic acid has a protective effect on your joints. It is an important component of synovial fluid, which acts as a natural shock absorber and reduces joint wear and tear. As we age, natural levels of hyaluronic acid in the body decrease, which can lead to joint problems and skin aging. A dietary supplement containing hyaluronic acid may be an effective solution(S).

What is the dosage of hyaluronic acid in Zell Boost?

Zell Boost for women contains 250 mg of hyaluronic acid.

Zell Boost for men contains 150 mg of hyaluronic acid.

What are the side effects of hyaluronic acid?

The European Food Safety Authority (EFSA) has found a daily dose of up to 430 mg of hyaluronic acid to be safe. As a naturally occurring polysaccharide in the human body, hyaluronic acid is generally very well tolerated.

What Vitamin D3?

Vitamin D3 is also known as the sun vitamin. This is because the vitamin is synthesized in our skin when it is exposed to the sun. Unfortunately, however, sun exposure increases the risk of skin cancer. Although the vitamin is also found in some foods, such as salmon, tuna or some mushrooms, it is only found in such small amounts that the daily requirement cannot be met through food.

How does vitamin D3 promote healthy aging?

Vitamin D3 is essential for the normal function of our immune system and contributes to the normal function of bones, teeth and muscles by absorbing and storing calcium and phosphorus.

Many organs and tissues of the body have receptors for vitamin D3, suggesting important functions beyond muscle and bone health(S).

Studies show that higher levels of vitamin D3 are associated with significantly lower rates of cancer, low risk of cardiovascular disease, and fewer negative emotions(S, S , S, S). Also, increased intake of vitamin D3 was associated with a lower risk of all-cause mortality(S).

What is the dosage of vitamin D3 in Zell Boost?

Zell Boost for men and women both contain 0.015 mg of vitamin D3. This is 100% of the EFSA recommended daily dose.

What is vitamin B12?

Vitamin B12 is an essential vitamin for the body, but it cannot be produced by the body itself. It is found in animal foods, often because pet foods themselves are supplemented with B12.

How does vitamin B12 promote healthy aging?

The risk of vitamin B12 deficiency increases with age. Vitamin B12 deficiency can lead to hematological, neuropsychological, and cardiovascular diseases, among others, and is also associated with a decline in cognitive performance(S). Even concentrations in the lower normal range are associated with poorer memory performance(S). Furthermore, vitamin B12 deficiency can lead to impaired DNA synthesis and genomic instability(S). An adequate supply of vitamin B12 supports nerve function, red blood cell formation, cell division, and DNA synthesis.

What is the dosage of vitamin B12 in Zell Boost?

Zell Boost for men and women both contain 0.004 mg of vitamin B12. This is 100% of the daily dose recommended by the EFSA.

What are the side effects of vitamin B12?

EFSA has classified vitamin B12 as safe and has not set a maximum daily value. Even at daily doses of up to 0.025 mg, no side effects were found(EFSA).

What is folic acid?

Folic acid or vitamin B9 is an essential vitamin from the vitamin B group. Our body can not produce folic acid itself, so our need must be covered by the diet. In addition to dietary supplements, folic acid is contained, for example, in intestines, Brussels sprouts or sprouts.

How does folic acid promote healthy aging?

Folic acid functions as a coenzyme in single-carbon transfers in the synthesis of nucleic acids (DNA and RNA) and in the metabolism of amino acids. One of the most important folate-dependent reactions is the conversion of homocysteine to methionine in the synthesis of S-adenosyl-methionine, an important methyl donor. Folic acid is further necessary for the methylation of deoxyuridylate to thymidylate in the formation of DNA. This process is essential for proper cell division(S).

Low levels of folic acid in the blood are associated with poor mental function and increased risk of dementia. Even a technically normal but low folic acid level may increase the risk of mental impairment in older adults(S). Adequate folic acid intake may also protect against Alzheimer's disease(S). Folic acid also supports our immune system and reduces fatigue(EFSA).

What is the dosage of folic acid in Zell Boost?

Zell Boost for men and women both contain 0.02 mg of biologically active folic acid (folate: L-5-MTHF). This is 100% of the EFSA recommended daily dose.

What are the side effects of folic acid?

EFSA has set a maximum daily value of 1mg for folic acid supplements(EFSA). No side effects have been observed up to a daily value of 5mg.

What is Biotin?

Biotin, also known as vitamin H or vitamin B7, is an essential vitamin from the group of B vitamins. The word "biotin" comes from the ancient Greek word "biotos", which means "life" or "food".

How does biotin promote healthy aging?

Biotin works synergistically with other B vitamins, such as B12 and B9, which are also included in Zell Boost. Biotin is involved in energy production through the metabolism of carbohydrates, proteins and fats. Biotin is essential for the production of RNA and DNA.
