In older adults with low selenium levels, higher baseline TSH levels are linked to a 35% increased risk of dying from cardiovascular disease over 10 years. Taking selenium and coenzyme Q10 supplements appears to remove this increased risk.

Similar Assertions

In older adults with low selenium levels, taking 200 micrograms of selenium and 200 milligrams of coenzyme Q10 daily for four years is associated with an increase in free triiodothyronine and a decrease in free thyroxine, indicating a change in thyroid hormone conversion that may influence metabolic and cardiovascular health.

In older adults with low selenium levels, taking selenium and coenzyme Q10 supplements for four years results in a smaller rise in thyroid-stimulating hormone (TSH) levels compared to taking a placebo, and fewer people reach the TSH level that defines subclinical hypothyroidism.

In older adults with low selenium levels, low levels of the thyroid hormone fT3 are linked to poorer mental and physical well-being. Taking selenium and coenzyme Q10 supplements removes this link and improves energy levels, reduces bodily pain, and enhances social functioning.
