Are Herbalife Shakes Safe During Pregnancy?
By Dogus Dilan, Herbalife Independent Wellness Coach · Last updated 10 August 2026
The honest answer is: Formula 1 isn’t formulated with pregnancy in mind, and the framing it’s built around — weight management through an energy-restricted diet — is specifically what the Royal College of Obstetricians and Gynaecologists advises against during pregnancy. This isn’t about a dangerous ingredient — it’s that a product designed for calorie control doesn’t match what a pregnant body actually needs, which is a nutrient-dense diet without intentional weight loss. If you’re pregnant and considering any Herbalife product, the right first step is a conversation with your midwife or GP, not this article alone.
This Isn’t About Ingredient Danger — It’s About the Framing
It’s worth being precise here, because the concern isn’t that Formula 1 contains something toxic. RCOG’s own guidance is direct: “trying to lose weight by dieting during pregnancy is not recommended as it may harm the health of your baby.” The British Dietetic Association says the same — “avoid intentional weight loss during pregnancy” — and recommends only pregnancy-specific multivitamin supplements, not general adult products.
There’s a telling detail in the research behind meal replacements too: the 2019 Oxford meta-analysis we cite in our general weight-loss evidence guide explicitly excluded pregnant women from its studies. The evidence base for “meal replacements work” simply doesn’t extend to pregnancy — it was never tested for it.
Nutrient Needs Change During Pregnancy — Formula 1’s Don’t
Formula 1’s 25 vitamins and minerals are calculated against the standard adult Reference Intake — the same 2,000 kcal, 50g-protein baseline used across all its labels. Pregnancy changes several of these requirements specifically: folic acid needs increase (400mcg a day is the NHS-recommended amount before and during early pregnancy, from a pregnancy-specific supplement, not a general multivitamin), and iron requirements typically rise too. A product formulated around general adult nutrition isn’t calibrated for those pregnancy-specific increases.
What About the Caffeine-Containing Products?
This is where Herbalife’s own labelling is actually explicit. Products containing caffeine — including Instant Herbal Beverage (87.5mg per serving) — carry a stated caution for pregnant or breastfeeding women, reflecting NHS guidance that pregnant women should stay under 200mg of caffeine a day from all sources combined. That’s a hard, specific limit worth knowing regardless of which product it comes from — coffee, tea, or a Herbalife shake alike.
Formula 1 itself doesn’t contain caffeine — but if you’re combining it with tea or other caffeinated products in the range, that 200mg total is the number to track, not any single product’s amount.
If You’re Considering Any Herbalife Product While Pregnant
Speak to your midwife or GP before starting, and bring the actual product label with you rather than describing it from memory — they’ll want to see the real ingredient and nutrient breakdown to give you accurate advice for your specific situation. This applies whether you’re currently using Formula 1 and have just found out you’re pregnant, or you’re considering starting it. Neither this article nor any product page is a substitute for that conversation.
