What about Coenzyme Q10 supplements for pregnant women and breastfeeding mothers, you ask. Well, yes, that seems to be a logical question.
Coenzyme Q10 is an essential factor in the cellular process of energy production. It plays an important role in antioxidant protection of the cells. It helps to maintain good endothelial cell function [Littarru 2010].
And, pregnancy is certainly a time when women need extra energy. Ditto when they are breastfeeding.
Similarly, pregnancy and breastfeeding are times of increased oxidative stress and thus increased need for antioxidant protection. Pre-term mothers and infants, in particular, need extra antioxidant defense [Abuhandan 2015].
Coenzyme Q10 and pregnancy: the evidence
The best study we have to date – a randomized controlled study – enrolled 235 pregnant women. 118 women were randomly assigned to take 200 milligrams of CoQ10 daily from week 20 of the pregnancy until delivery. 117 women were assigned to take a matching placebo for the same period [Teran 2009].
Only 17 women in the CoQ10 treatment group developed pre-eclampsia compared with 30 women in the placebo group. The 43% reduction in the risk of developing pre-eclampsia was statistically significant.
The researchers concluded that daily supplementation with CoQ10 reduces the risk of developing pre-eclampsia [Teran 2009]. There were no adverse effects of taking 200 milligrams of CoQ10 from week 20 of the pregnancy until delivery, neither for the mother nor for the baby.
CoQ10 and a safe pregnancy
Blood pressure disorders are a major cause of pregnancy complications throughout the world.
One plausible hypothesis is that inadequate antioxidant protection leads to increased cell damage caused by free radicals. Increased endothelial cell damage leads to the development of pre-eclampsia [Palan 2004].
- Coenzyme Q10 is plays a crucial role in improving endothelial function.
- CoQ10 has a hypotensive effect [Littarru 2011].
- Accordingly, CoQ10 as a lipid-soluble antioxidant may play a significant role in prevention of pre-eclampsia.
In addition, Coenzyme Q10 supplementation can improve the cellular production of energy at a time – during pregnancy and during breastfeeding – when more energy is needed.
Talk with your physician or gynecologist about CoQ10 supplements
Women planning a pregnancy should talk with their gynecologists about taking a Coenzyme Q10 supplement during the pregnancy.
- In numerous clinical studies, oral CoQ10 supplementation has been shown to be safe, well-tolerated, and effective [Littarru 2010]. It is affordable.
- Coenzyme Q10 has very low toxicity and does not induce serious adverse effects in humans [Hidaka 2008].
- Studies have shown that there is considerable variation in the absorption and bio-availability of oral CoQ10 supplements [Lopez-Lluch 2018].
Not all Coq10 supplements equally good
The CoQ10 supplements on the market are not equally good. It is important to choose a well-formulated CoQ10 supplement with documented absorption and efficacy.
For example, the Q-Symbio study showed that daily supplementation with 300 milligrams of CoQ10 resulted in significantly improved symptoms, quality of life, and survival in chronic heart failure patients [Mortensen 2014].
In the KiSel-10 study, daily supplementation with 200 milligrams of CoQ10 and 200 micrograms of a high-selenium yeast preparation resulted in significantly reduced risk of death from heart disease, better maintained heart function, and improved quality of life in senior citizens [Alehagen 2013].
In both studies, the same CoQ10 preparation was used.
CoQ10 and fertility issues
Please note: there is a growing literature about the effects of Coenzyme Q10 supplementation on male (and female) fertility. That is an article for another day.
