Why Amino Acids Matter During Perimenopause
Perimenopause is a natural transitional phase marked by fluctuating hormone levels — particularly oestrogen, progesterone, and sometimes testosterone. These shifts can result in a wide range of symptoms, including:
-
Fatigue and low energy
-
Mood swings or low mood
-
Difficulty sleeping
-
Brain fog
-
Muscle loss
-
Decreased libido
Amino acids, the building blocks of protein, play crucial roles in:
-
Neurotransmitter production (e.g. serotonin, dopamine)
-
Muscle repair and preservation
-
Immune regulation
-
Hormonal signalling and detoxification
Supplemental amino acids can be especially useful if protein intake is low, digestion is impaired, or your body is under more physiological stress.

Synergy Beyond Amino Acids
PERI isn’t just about amino acids — it’s a botanical, and probiotic blend designed to address multiple aspects of perimenopausal wellbeing.
Here’s how it supports you holistically:
-
Adaptogens like Maca Root and Siberian Ginseng to help with stress and fatigue
-
Phytoestrogens from Red Clover and Soy Isoflavones to help balance oestrogen activity
-
Cognitive & circulatory support from Ginkgo biloba, Pine Bark, and CoQ10
-
Gut health support via Lactobacillus acidophilus
-
Antioxidants like Resveratrol, Green Tea Extract, and Hesperidin
Together, these ingredients help regulate hormonal shifts, maintain energy and focus, and reduce common discomforts like brain fog, irritability, and hot flushes.
Do You Still Need Protein in Your Diet?
Absolutely. While amino acids in PERI are incredibly supportive, they work best alongside adequate dietary protein — especially for preserving muscle mass, skin elasticity, and metabolic health.
Aim for:
-
Protein-rich meals (chicken, fish, tofu, legumes)
-
Post-exercise recovery support
-
Whole foods with fibre and healthy fats
Think of PERI as your foundational support — ensuring your body gets a daily dose of targeted, bioavailable nutrients even on your busiest days.
