Beta-carotene, an essential nutrient and potent antioxidant, has raised some concern among ex-smokers due to certain scientific studies. It is true that some studies have linked a higher chance of lung cancer with smokers and ex-smokers who take beta-carotene supplements. However, it is crucial to note that these studies typically involve beta-carotene 'megadoses', typically around 20-30 mg. At Together Health, we use only 0.5 mg of beta-carotene in our product, amounting to just 1.6% of the doses used in the studies. This reduction in dosage is a reflection of our cautious approach to nutrient levels, avoiding megadoses due to potential unforeseen consequences. Unfortunately, it's unclear where the safe level of beta-carotene lies for ex-smokers, but our lower dosage is far from the amounts used in the studies that indicated risk. Moreover, our beta-carotene is not isolated but incorporated into a whole food complex, thus mimicking more closely the natural presence of beta-carotene in foods like carrots. It is also worth noting that a diet rich in fruits and vegetables, which naturally contain beta-carotene, has been associated with a reduced risk of cancer. However, the science is still evolving, and as always, we encourage our customers to seek medical advice when necessary.
