Up to 85% of women suffer from morning sickness which varies from mild nausea to severe nausea and vomiting several times a day (otherwise known as hyperemesis gravidarum). It usually starts around 6 weeks gestation and resolves by week 14-16 of pregnancy. Morning sickness is debilitating, affects a woman’s ability to work and as a result creates a significant public health issue that has a psychological, emotional and social impact on women and their families and an economic impact on society. Women need to be educated on what aggravates morning sickness and they need a solution that is not

There are a few factors that can help ease nausea and vomiting during pregnancy:
published in peer-reviewed journal articles to reduce the frequency and severity of nausea and vomiting in pregnancy and is equivalent to ginger in efficacy*. In most studies, capsules were taken 2-3 times daily.
chromium, biotin and alpha lipoic acid in particular may help ease morning sickness. Other nutrients play a role in carbohydrate metabolism including nicotinamide, pantothenic acid, riboflavin-5- phosphate, thiamine hydrochloride, pyridoxal-5- phosphate, hydroxocobalamin, magnesium, manganese and zinc.
has been shown repeatedly in studies published in peer-reviewed studies to be effective. However the longest study was only 3 weeks, therefore safety hasn’t been established for the entire first trimester although it should be noted that in the 3 week study, effectiveness increased over time. Most women will start taking ginger around 6 weeks and keep taking for at least 6-8 weeks. I find advising them to drink ginger tea and chew on crystallised ginger as needed is helpful.

About 10% of known pregnancies end in miscarriage. Most early miscarriages occur because of chromosomal abnormalities due to errors introduced during meiotic disjunction in the oocyte or sperm. A recent study showed that low total antioxidant status is associated with miscarriage (Omeljanuik et al, 2015). Zinc and selenium deficiencies can cause chromosome changes due to the fact they are an essential component of genetic material therefore a deficiency in zinc and/or selenium is associated with an increased risk of miscarriage. Alpha lipoic acid is an excellent antioxidant that recycles vitamins C, E and CoQ10 and a study has recently shown that 100mg of alpha lipoic acid with 100mg of magnesium taken daily from week 14 reduced the risk of preterm labour (Parente et al. 2014).

Hyperhomocysteinaemia is the most common thrombophilia and this thrombophilic tendency is minimised by an adequacy of folate, vitamins B2, B6 and B12. The activated forms of these B vitamins overcome any MTHFR single-nucleotide polymorphisms (SNPs). Interestingly, white Caucasians have a higher incidence of the MTHFR C677T SNP with 4-25% homozygous and 40-50% heterozygous compared to black people who only have 2% homozygous and 20% heterozygous. All B vitamins need to be at adequate levels during gestation for the child to reach its full genetic growth potential. If the mother becomes depleted of nutrients at any stage later in the pregnancy this can lead to a growth restricted baby or a small for gestational age baby and this is linked to a number of diseases later in life. If genes are not switched on or off at the right time during embryogenesis then things will go wrong – cell replication won’t happen as it should. Higher levels of serum B12 led to a higher live birth rate by 26%. Ref: Gaskins et al. 2015, American Journal of Clinical Nutrition
Folic acid needs to be converted to dihydrofolate (DHF) and then tetrahydrofolate (THF) – dihydrofolate reductase is the enzyme that metabolises DHF into THF. If a woman is heterozygous for C677T then she has a 40% reduction in the ability to metabolise folic acid into its active form. If she is homozygous she has a 70% reduction. This means that folic acid is the wrong type of folate for her – she needs 5-MTHF if she is homozygous or if she is heterozygous for both C677T and A1298C. Folate should always be combined with adequate B12 - 5-MTHF in combination with B12 (and B6 and B2) is required to convert homocysteine into methionine which is then converted into SAMe (essential for healthy neurotransmitter function). Also B12 is just as important as folate for preventing neural tube defects (Ray et al., 2007). A recent meta-analysis confirms a significantly increased ASD risk in children with C677T polymorphism and that periconceptional folate supplementation reduces the risk (Pu et al., 2013) References

Methylcobalamin and adenosylcobalamin are both active forms of B12 that have different biochemical roles. Methylcobalamin is primarily involved in the formation of blood, homocysteine metabolism and development of the brain during childhood. Adenosylcobalamin is primarily involved in carbohydrate, fat and amino-acid metabolism and a deficiency interferes with the formation
Therefore, supplementation must either be a combination of both active forms OR hydroxocobalamin which easily converts to either form and it has been shown that the

in preventing neural tube defects and it is recommended that serum B12 levels should be higher than 221pmol/L prior to pregnancy to reduce the risk (Ray, 2003, Ray et al., 2008, Molloy et al., 2009)

RANZCOG recommends that there is little evidence to support routine supplementation of the fat soluble vitamins A, betacarotene, E and K during pregnancy. However they are supportive of vitamin D supplementation and if the woman has proven cholestasis then vitamin K supplementation is required because of reduced vitamin K absorption. Vitamin K has poor placental transfer which is why babies are given vitamin K at birth. Vitamin E is easily obtained from the diet – RDI is 7mg.

milk and full fat yoghurt, eat meat, eat butter over margarine and even cook with butter, seafood, eat eggs regularly (eggs are a powerhouse of nutrients including iodine so they are fantastic in pregnancy). We all need a certain amount of saturated fat in our diets, it is trans-fats that are harmful. Cod liver oil can vary from 270mcg to 1500mcg per teaspoon (best to avoid in case of
1 cup full cream milk = 92mcg 1 cup full fat yoghurt = 83mcg Chicken breast = 36mcg 85gms mackerel = 42mcg 28 grams cheddar cheese = 90mcg 2 eggs = 186mcg 1 T butter = 130mcg ½ cup ice cream (as a special treat!) = 162.9mcg If you have a pregnant woman who is vegetarian and doesn’t eat dairy products then you should advise her to take a vitamin A supplement – no more than 800mcg or 1500iu of retinyl palmitate. Be wary of cod liver oil – many women read on the internet that this is a good thing to take during pregnancy (Weston A. Price). We commonly see betacarotene in prenatal supplements, however there are a lot of people who can’t convert beta-carotene into vitamin A – approximately 25% of white people* and one estimate is 45% of the population as a whole. Betacarotene is unstable in supplements and easily obtained through the diet. Also be aware that beta-carotene supplementation has been shown to inhibit the absorption of lutein by more than 50%*. *Reference – The Textbook of Natural Medicine, Pizzorno & Murray.
Iron deficiency anaemia affects 22% of women in the Western world compared with 52% in non-industrialised countries and the risk increases with each subsequent pregnancy. It is important to get iron supplementation right during pregnancy and blood tests for ferritin should be done at the end of each trimester to assess the requirement for
We know that iron-deficiency anaemia is associated with an increased risk of maternal mortality (especially if she has a postpartum haemorrhage), infection, premature delivery, low birthweight and may adversely affect the baby’s brain development and neurocognition (Lozoff, 2006). However we know that excess iron intake has also been associated with adverse outcomes including low birthweight and premature delivery (Casanueva, 2003). High dose iron supplementation may cause constipation and may reduce the absorption of other minerals such as zinc, copper, chromium, molybdenum, manganese and magnesium (Hambidge et al., 1987) (O’Brien, 2000) and vice versa, zinc and manganese supplementation may impair iron absorption so we need to get the balance right! We know that iron supplements cause nausea and vomiting in the first trimester, so what do we do if the woman is iron deficient? Several studies have shown intermittent iron supplementation to be just as effective as daily iron

“Normal” is 20-250ug/L, however in NZ in recent years they have changed the lower normal range to 30ug/L. I find in practice that women feel better with a ferritin over 50ug/L (pregnant or not). Preferably we need to boost ferritin prior to conception – 80ug/L or higher is ideal. Check c-reactive protein as well though because ferritin can be falsely raised with inflammation.

Zinc sufficiency is important during pregnancy. Zinc deficiency greatly affects the women’s labour as sufficient zinc is vital for an on-time, quick labour, less tearing and helps prevent postnatal depression. It has also been found that zinc deficient babies cry excessively and are difficult to console (Lazebnik et al). Zinc is required for more than 300 enzyme reactions including serotonin and GABA synthesis and in fact has the second highest concentration of all transition metals in the brain. There is a TGA warning that has to go on to all supplements containing more than 25mg of zinc that it can be harmful if taken in large doses or over a long period of time. That is because zinc antagonises copper, however you need 60mg of zinc daily before it starts affecting copper levels and treatment of high copper levels using zinc is usually 100mg daily. Oral zinc supplementation during the first trimester can cause nausea. Zinc supplementation in the absence of food at any time, pregnant or not can have an emetic
system and therefore reduces the likelihood of causing nausea.

Copper levels naturally rise during pregnancy due to rising oestrogen levels which increase hepatic caeruloplasmin synthesis therefore increasing serum copper levels and this is well documented in the literature (Crayton & Walsh, 2007). Through clinical experience I have discovered that women usually have high levels of copper in the blood and low zinc prior to pregnancy. Adding more copper during pregnancy increases the risk of high copper levels and subsequent postnatal depression (Crayton and Walsh, 2007) In pregnancy, excess copper levels (i.e. higher than 45 umol/L (micromole) – normal reference range pre-pregnancy is 11-22 umol/L) can be associated with intrauterine growth restriction, preeclampsia and neurological disease. There is also an interesting case study of a link between copper excess in pregnancy and autism in the baby (Walker et al, 2011).

Maintaining a euthyroid condition therefore requires continual access to dietary iodine, a challenge that grows during pregnancy” (Forbes, 2014). However even with daily iodine supplementation during pregnancy, T4 levels still drop in the second trimester without an increase in TSH suggesting it is a normal physiological function (Brucker-Davis et al., 2013) Soy milk and raw cruciferous vegetables are goitrogenic. Good food sources include fish, shellfish, miso soup, eggs and iodised salt (71mcg in ¼ tsp iodised salt, 100mcg in ¼ tsp of Nirvana Organics Himalayan crystal salt).

We do need to careful about not overdoing it when it comes to iodine supplementation in the first trimester. Hcg, the pregnancy hormone naturally stimulates the thyroid in the first trimester and so we see a drop in TSH. A hyperthyroid state in the first trimester is associated with increased nausea or vomiting (NVP) or hyperemesis gravidarum and in fact it has been suggested that a woman who doesn’t suffer NVP could be hypothyroid (Forbes, 2014) Also, excess iodine of more than 200mcg per day in the first half of pregnancy has been associated with an increased risk of a TSH higher than 3 and subclinical or even overt hypothyroidism later in pregnancy (Rebagliato et al., 2010) Iodine supplementation should be limited to 150mcg in the first trimester to err on the side of caution with the balance coming from her diet. The RDI of iodine in pregnancy is 220mcg daily.

Result – after 8 weeks the 4mcg group had significantly lower HbA1c compared to baseline and both supplemented groups had significantly lower fasting glucose and insulin levels compared to baseline. Biotin in high doses has been found to substantially lower fasting glucose in type II diabetics without side effects and a review article has suggested that chromium and biotin in combination may be effective in the prevention and treatment of gestational diabetes.

Antioxidants may have a beneficial effect. Alpha lipoic acid is an excellent antioxidant as well as being involved in glucose metabolism and an interesting study on rats showed that supplementation with ALA resulted in a significant reduction in congenital abnormalities and intrauterine growth restriction compared to diabetic rats who were not treated. The authors stated that the study highlighted the possible role of antioxidants in the normal processes of embryo survival, growth and development.
